Owners of orchards, vineyards and berry plantations are well aware of the problem of crop processing. Effective method her solution is cold-pressed juice. This process allows you to preserve the vitamin value of fruits and berries for a long time without building a bulk storage facility.
The main mechanism of the country “canning shop” is a press for squeezing juice. It helps to quickly and without loss process hundreds of kilograms of ripe crops.
ABOUT existing varieties We will discuss the principles of operation and cost of equipment for obtaining juice in this article. Information about the features will be useful for home craftsmen self-made powerful "juicer".
Types and principles of operation of juice presses
Installations designed for squeezing juice are divided into mechanical, hydraulic, electro-hydraulic and pneumatic.
The most common mechanism is a mechanical screw press.
Screw press for extracting juice is simple and reliable
The principle of its operation is clear at first glance: crushed fruits are placed in a container with holes, grapes or berries are poured. After this, by rotating the handle, the screw is activated, lowering the flat piston. The squeezed juice flows through holes in the casing into a tray, and from there it goes into jars or other containers.
In addition to stainless steel, solid beech wood is used to make the casing. A drainage grid is made from it. It consists of two halves connected by metal hoops.
A modernized version of such a device is manual Hydraulic Press for apples and grapes.
It does not have a perforated container to separate the juice. Instead, several wooden drainage frames are used. Bags with crushed raw materials are placed between them. A manual hydraulic jack develops a large force (from 1 to 5 tons). Thanks to this, the volume of juice obtained reaches 70% of the volume of fruit.
The original squeezing method is implemented in the Grifo hydraulic press. It does not have a hydraulic jack, but a powerful “barrel” membrane is installed. It expands under the pressure of tap water (1.5-2 atm.) and squeezes the juice through the perforated wall of the casing.
Hydropress Grifo - connected to the water supply and squeezed out the juice
A pneumatic press works on a similar principle. Only the pressure membrane in it is filled not with water, but with compressed air from the compressor.
Pneumatic press for squeezing juice. The screw piston was replaced by a rubber membrane
Since all juice presses are paired with choppers, a few words need to be said about these devices. The simplest mechanism is a steel drum-grater placed in a casing with a loading neck. By rotating the handle, the chopper is activated, turning the fruit into fine crumbs and pulp.
A more advanced option is an electrically driven device. Minimum physical effort and maximum productivity are the main arguments in its favor.
It should be noted that the productivity of mechanical presses is low (10-30 liters per hour). However, for most country farms it is quite enough.
To improve the quality and increase the yield of juice, two methods are used:
- Container bags for crushed fruits.
- Wooden drainage grates or stainless steel “pancakes”.
Both methods improve the removal of juice from the middle of the compressed volume. Without such drainage, the middle layers of crushed fruit are squeezed out worse than the top and bottom layers. An additional advantage of using bags is the release of pulp from the juice.
Large volumes of processing require the use of an electric drive. Here two types of equipment can be distinguished: a traditional screw mechanism driven by a pair of “electric motor-hydraulic jack” and a screw press operating on the principle of a meat grinder.
A screw press juicer with an electric motor is designed for processing berries, grapes and tomatoes. When crushing the raw material, the auger presses it through a sieve and produces juice with big amount pulp.
The screw press is a relative of the household juicer
Approximate prices
The cost of manual screw presses for squeezing juice directly depends on their capacity. The price for devices with a working volume of 10-15 liters ranges from 9,000 to 15,000 rubles. For a manual press that holds 25 liters of raw materials, you will have to pay at least 20,000 rubles.
Average price of home powered “juice presses” hydraulic jack, is 19,000 rubles. A pneumatic press for squeezing juice from apples can be purchased for 34,000 rubles. Behind hydraulic device membrane type, sellers ask for 94,000 rubles.
How to make a juice press with your own hands?
The most difficult part of a manual juice press is the powerful screw. It is impossible to do it without the help of a qualified turner. Moreover, every car owner has a mechanism that is perfect for squeezing juice. This is a hydraulic or mechanical jack. Using it, you can make a good homemade juice press.
The main task is to weld a strong frame from a metal profile into which the jack will rest. For this purpose, you can take trimmings square pipe(section 40x40 mm, wall thickness not less than 3 mm).
When making a drawing of the press, the height of the frame is chosen based on the height of the jack, the thickness of the linings, drainage grates and bags of raw materials. The width of the frame is made such that the juice tray can easily fit into it.
In order to make the juice press with your own hands as stable as possible, three pieces of square pipe (15-20 cm long) need to be welded to the lower belt of the frame on both sides. A stand made of boards or OSB boards will rest on these “legs”.
The drainage grate should only be made from natural wood(oak, beech). The thickness of the drainage grid boards must be at least 20 mm.
For sewing bags you can take different fabric(jute burlap, linen fabric, cotton calico, synthetics). The main thing is that it is strong enough so that it will not be torn apart by the pressure of the jack.
In conclusion, let’s look at photographs of a working example of such a press. Without resorting to welding, the master decided to make a frame with bolted joints, using a powerful angle and a profile pipe.
A piece of laminated chipboard countertop was used for the bottom base plate.
But the master chose the wrong material for the drainage grid. Instead of natural wood, he used OSB board, making cuts in it for the outflow of juice. We do not advise you to repeat this mistake because particle boards toxic phenol-formaldehyde glue is present.
Drainage grate for the press - only wood, not chipboard!
In general, the homemade juice press turned out to be simple, reliable and efficient.
But more complex design DIY hydraulic press. Here the master decided to use a screw as a fastener for a fruit bookmark placed in a perforated stainless steel casing. He placed a hydraulic jack under the frame. The supporting platform is made not stationary, but sliding. The jack moves it up the frame profile.
In this press, the screw does not squeeze out the juice, but only fixes the bookmark
" Apples
Apple trees periodically provide amateur gardeners with such a large-scale harvest that there is nowhere to put the excess fruit. In addition to jam and compotes, there remains one more option for processing fruits - juice. But many people do not get involved with this type of workpiece due to the high labor intensity of the process. Ordinary household juicers simply cannot cope with large volumes of raw materials, and not everyone is ready to buy a professional machine for the season. But there is great option– quickly and efficiently squeeze juice from apples using a home-made press.
To make a standard press yourself, you do not need special skills or drawings. Anyone can measure, saw off a strip, hammer a nail or tighten a nut if desired. It is not necessary to own a welding machine; any design can be reproduced in wood using ordinary gardening tools .
To make a home press from tools, you will need a hacksaw for wood and metal (or a grinder), a welding machine, screwdrivers, pliers, and a hammer. As for materials, the following are mainly used:
- metal channel;
- wooden blocks, slats, boards;
- self-tapping screws, bolts and nuts;
- tank or barrel, steel sheet from of stainless steel;
- bench screw and nut, valve, threaded rod or jack - depending on the chosen design;
- durable fabric with good drainage properties for apple bags: calico, cotton, jute burlap, linen.
It is better to make wooden elements from oak, birch or beech, since materials from biologically active tree species (spruce, pine) can change the taste of the juice. Under no circumstances should drainage grates be made from chipboard: fine dust impregnated with phenol-formaldehyde glue will get into the product.
Types of designs: diagrams and drawings
The main thing in the press is a solid base and working mechanism.
Operating principle of the device:
- layer by layer through drainage grates prepared raw materials for pressing are stacked(chopped apples) in fabric bags;
- by means of a mechanism oppression falls from above and presses the juice.
A good press squeezes out 65-70% of the juice, leaving an almost dry pulp. It’s quite possible to make one with your own hands.
Constructions homemade press differ in the principle of operation of the main mechanism:
- Screw.
- Jack based: mechanical and hydraulic.
- Combined.
In the bulk of structures, the pressure is from above, but V combined version compression occurs in two directions: using a screw mechanism on top and a hydraulic jack on the bottom.
The juice press consists of the following parts:
- sustainable bed;
- quadrangular or cylindrical frame, inside which bags of chopped apples are folded;
- wooden gratings, with which the bags are transferred so that they do not spread;
- piston-gne t, directly exerting pressure on the cake;
- thrust bearing for a jack;
- working mechanism: screw with handle, mechanical or hydraulic jack;
- bowl-tray.
The main body can be:
- single perforated: the juice will flow through the holes along the walls and through the bottom into the pan;
- double: a solid casing with a slightly larger diameter is placed on a perforated metal cylinder;
- in the form of a solid metal body with one drain hole at the bottom;
- collected from wooden slats connected by hoops, − barrel. The walls serve as a drainage grid.
There may be no body at all- simply a pyramid of wooden lattice frames in a tray with a mouth at the bottom, under which a container for juice is placed.
This design easy and quick to install. For the bottom plate, you can take a piece of countertop, for example.
Worm gear or hydraulic jack: what to choose?
The screw (worm) mechanism in the press is implemented in the form of a large screw (threaded axis) with a nut or mechanical jack. The latter option is much simpler - you can buy it at a spare parts store or take it out of the trunk of a car; you don’t need to look for, adjust, grind or weld anything.
Designs based on a hydraulic jack are much more productive(force from 1t) than mechanical ones, and require a minimum of human labor. Hydraulic bottle jacks make it possible to squeeze juice quickly and in large volumes. They fit comfortably into any design.
You can design a press with a removable mechanism, then you don’t have to buy a special jack, but you can use the one on duty in the trunk. After all, the apple harvest is not good every year.
Making a press yourself
The press needs a stable, strong support - a bed. The simplest thing is to assemble it from wooden blocks using screws. To make a metal frame you will need a welding machine and a channel.
The dimensions of the frame depend on the diameter of the working body or the parameters of the drainage grids. Therefore, if you are planning a hull structure, then you need to prepare the container in advance.
The simplest frame press with a worm mechanism
Welded stable structure. A hole is cut in the center of the upper channel for the screw nut (you can use an old bench or order it from a turner). The nut is welded into the frame.
Then Assembling a wooden drainage grate, which consists of two layers of slats packed perpendicular to each other. The thickness of the slats is not less than 20 mm. It is also necessary to install a stand made of bars. A clamp for the pressure part of the screw is attached to the top board - any suitable shape metal part(can be installed with epoxy glue).
The tray is made of stainless steel sheet, in the front part the spout-drain is arched. All that remains is to substitute a pan or other container. The result is abs.
The bed for a hydraulic press is assembled according to the same principle as for a screw press. The easiest way to use a body is to take a ready-made metal or wooden barrel. A hole is cut at the very bottom and equipped with a drain spout.
If wooden barrel not completely sealed - even good. The juice will drain in several directions at once, and in the end it will still end up in the pan. It is better to put a plastic casing on top of such a structure larger in diameter to avoid splashing.
You can make a wooden case yourself:
- Will need: several boards of equal size (can be parquet), two strips of stainless steel and self-tapping screws with an anti-corrosion coating.
- The boards are screwed on top and bottom with self-tapping screws to the stripes at a distance of approximately 10 mm.
- Strips with boards are bent in the form of a circle, the ends of the strips are bolted together.
- A plastic bowl of suitable diameter can be used as a tray. with a drain cut out at the bottom for juice.
Another important element is the jack stop.. Usually made of wood: you need to knock down the slats and cut out a circle from the resulting canvas slightly smaller than the diameter of the working body. You can use a grinder to cut out a support from a stainless steel sheet.
Drainage gaskets are made in the same way as in the description for a screw press, but they are given a round shape.
The end result should be a design similar to the one in the photo.
Preparation of raw materials
Spin principle apple juice simple - the finer the raw materials are chopped, the more product will be obtained at the exit. It is best to use a special chopper (crusher), since finely chopping several buckets of apples by hand is theoretically possible, but in fact difficult to implement. An electric meat grinder for large volumes is also not an option: it roars, howls, gets hot, and may eventually burn out. You can also make a suitable crusher yourself.
The simplest design of a homemade crusher
From moisture resistant plywood or sheet stainless steel, a deep hopper is mounted lightly on the cone. For stability, two bars are attached to it from below. IN bottom part a wooden roller (preferably made of beech) with self-tapping screws wound in a spiral is cut into the container. You can use a regular kitchen rolling pin as a drum.. The axis of rotation of the roller comes out, a drill is inserted into it and the process begins.
Some people simply crush apples in a bucket using a construction mixer.
The process of squeezing juice from apples at home
After the raw materials are prepared, they laid out in fabric bags or wrapped in pieces of fabric like an envelope. Next, the bundles are placed in a container, basket, or simply on the bottom of the structure in layers through drainage grates. Fits about 3-4 bags. The pressure is lowered from above, the juice flows into the pan. When the squeezing process is completed, the pulp is removed and the next batch is loaded.
The remaining cake after high-quality pressure is usually obtained dry and compressed into “tablets” (photo 16).
It is better to dispose of the pomace in compost heap. Worms reproduce very well on such material, creating valuable fertilizer for the garden.
The resulting juice can not only be drunk fresh, but also prepared for the winter:
- pasteurized rolled juice;
- apple wine several types;
- apple cider.
Apples are a very valuable product for health.. It is extremely imprudent and wasteful to bury and give away surplus crops to neighboring pigs. By building a couple of simple devices, you can quickly and easily process all the fruits. And in winter it will be so nice to take healthy and tasty amber drinks out of the cellar or refrigerator!
The end of summer, the beginning of autumn is the time to collect fruits, vegetables, apples, and grapes. And if the harvest is large, then a regular electric juicer will not cope. In this case, the garden needs a press for squeezing juice from fruits. Now there are a lot of offers on the Internet for various presses and crushers, hydraulic, screw, pneumatic, wooden, but the biggest disadvantage of these products is high price. Making a juice press with your own hands is not difficult; you need a little skill as a mechanic or welder. And the cost of a homemade press for grapes or apples is several times lower than a purchased one.
For a winemaker, such a device will make his work easier and save a lot of time. The simplest version of a home juicer is based on squeezing juice from the pulp of fruits or vegetables. The apples are first crushed with special crushers, a grape crusher is used, and then the juice is squeezed out of this mass. With this technology, pure juice without pulp comes out, ready for fermentation, or for pasteurization and further storage.
Simple DIY grape press
A screw press for grapes consists of: a base - a frame, a basket, a pressing device (shaft or jack), and a pressing piston. Other options for manufacturing the device are also possible. When choosing a material, it is not necessary to follow the description exactly and you can make your own drawings of the Persian.
Tools and materials for the press:
- Welding machine;
- Drill;
- Bulgarian;
- Tank – 50 liters;
- Metal channel 10-12 mm – 150 mm;
- Metal corner 40-50 mm – 3200 mm;
- Oak slats 40x25x400 mm – 50 pcs;
- Fabric – 1 sq.m;
- Jack – 1 piece;
- Faucet – 1 piece;
- Line 2 mm – 3 m.
How to make a juice press
1.Frame. The foundation is one of the most important elements press, the frame must be a very strong structure; the entire load during operation falls on it. The side parts of the press are made of metal corners 85 mm high. The upper and lower parts of the frame must be made from a channel 70 cm long; the structure can be further strengthened by welding gussets between the corners and the channel. All parts are welded at all points of contact. 
If a screw press design is used, then a nut for the screw must be welded to the upper channel. In addition to the metal frame, you can use wooden boards, thickness from 5 centimeters. The boards are fastened with 10-12 mm studs and tightened with nuts. Wooden press It’s easier to make, but the design can’t withstand heavy loads; for a small harvest, it’s quite a suitable option. The finished frame must be sanded and painted with a special metal paint. 
2.Abs tank.
This design uses a 50 liter stainless steel brew tank. A hole is drilled in the lower part of the boiler tank and a stainless steel tap is installed. Instead of a tank, you can use a regular saucepan suitable size. 
A grate made of oak slats is inserted into the container. The blanks are cut from oak boards (you can use parquet board), their height is equal to the height of the pan. Along the edges at the ends of the slats, holes of 2-3 mm are drilled through them and a fishing line or stainless wire is passed through them. By connecting all the planks, you get a kind of basket. 
There should be a gap of 2-3 mm between the slats, through which fruit juice will ooze. You can do without a pan at all by connecting the boards with galvanized steel hoops and placing the basket on a tray into which the squeezed liquid will drain. 
A plastic pallet from a large one can be used as a pallet flower pot or stainless steel kitchen sink. There are designs where the grape press is framed, there is no basket, the pulp is placed in fabric between drainage grates in several layers and pressed. 
3.Piston. The piston for the press needs to be made from the remaining oak boards, folding them crosswise, use a compass to draw a circle the right size and cut electric jigsaw. Twist the slats with stainless steel screws or tie them with copper and stainless steel wire. If you have a log on your farm, you can saw off a circle of the required diameter and height. 
4.Power mechanism.
The apple press uses a jack or screw as a pressing mechanism. In the device for squeezing juice, hydraulic car jack with a lifting capacity of 3 tons. For more confident work, you can use jacks that create a force of more than 3 tons. A screw for a press is more difficult to find, but every car enthusiast has a jack. You need to cut some boards under the jack to place it during the spin cycle. 
5.Filtration cloth. To filter the juice from apple fruits, you need a durable fabric that can allow moisture to pass through. The easiest option is to take a nylon sugar bag. Also suitable for filtration are nylon, lavsan, propylene, polyester, or use durable cotton material, dense flax, so as not to tear under pressure.
So, the manual fruit press is ready, how to squeeze out the juice? Insert the basket into the tank and place the filter material inside. Soft fruits, berries, citrus fruits are crushed without pre-treatment. Apples, carrots or other hard fruits must be crushed in a crusher or using pulp from a juicer, loaded into a basket, and covered with a lid.
Install the jack, substitute the receiving container, open the tap and slowly apply pressure. There is no need to try to squeeze out all the juice right away; you may damage the frame or the fabric will tear. Make three or four pumps, wait a while, then another three or four pumps, and so on. One bucket of apple pulp from a juicer yields 3-4 liters of pure juice; the crushed mass yields a little more.
Processing the harvest of berries and fruits is one of the most important tasks that not only farmers, but also owners of personal plots have to solve. TO technical devices, which greatly facilitate this process, is a juice press, which allows you to quickly and without significant physical effort turn fruits and berries into tasty juice rich in vitamins. On modern market There is a wide variety of such devices, but those home craftsmen who want to save money on their purchase can easily make such a press with their own hands.
Operating principle and types
All presses for squeezing juice from various berries and fruits can be divided into four main types:
- mechanical devices;
- hydraulic presses;
- electrohydraulic models;
- pneumatic type devices.
The most common due to its low cost and simplicity of design is a mechanical press. manual type. One of the main elements of its design is a perforated basket, into which crushed fruits (pulp) or berries are placed to extract juice. Fruits and berries are squeezed in such a device using a piston, the lowering of which (and the creation of the required pressure) is carried out by rotating the handle that drives the screw mechanism of the press. The juice formed during the pressure of the piston flows through the holes in the basket into a special tray, from where it is then poured into another container.
Stainless steel sheets or wood can be used to make a basket into which the raw materials for squeezing juice are loaded. hard rocks(for example, beech). In the second case, the design of such a basket is a drainage grid consisting of two equal parts connected to each other by metal hoops.
Modernized and, accordingly, more efficient version hand-held device is a hydraulic press that can be used to extract juice from apples and berries. Instead of a perforated container, the design of such a press uses several drainage frames made of hard wood. The crushed raw materials from which it is necessary to obtain juice are placed in fabric bags and placed between such frames, on which significant pressure (1–5 tons) is applied from above, created by a manual hydraulic jack. Using such a squeezing mechanism, you can obtain up to 70% of the juice from the total mass of the processed crop.
A hydraulic press does not necessarily involve the use of a jack as a mechanism that creates the required pressure. Thus, in one of the designs of such presses, this mechanism uses an elastic barrel-membrane, which expands under the influence of water supplied to it under a pressure of 1.5–2 atm from a regular water supply network. Expanding, such a press membrane acts on fruits and berries placed in a perforated basket, squeezing out juice from them, which flows through holes in the walls of the basket into a storage tray.
A pneumatic press for squeezing juice also works according to the principle described above. The only difference is that the expansion of the membrane barrel, also present in its design, occurs not under the influence of water filling it, but under pressure compressed air supplied from the compressor.
Since certain types of raw materials from which juice must be extracted are loaded into presses in crushed form, it is imperative to mention devices that help bring it into this state. The design of the simplest grinder is a steel drum, the walls of which are made in the form of a grater. Such a drum, which turns the raw materials loaded into it into fine crumbs, is placed in a casing with a loading neck. This simple and effective mechanism is activated by rotating a special handle. There are also more efficient and productive models of such units that are driven by an electric motor.
If we talk about the productivity of mechanical presses for squeezing juice, it is quite small and can be in the range of 10–30 l/hour. However, this performance is quite sufficient for devices used for domestic purposes.
In order to increase the percentage of juice yield from squeezed fruits and berries, as well as improve its quality, two methods are used:
- raw materials are loaded into presses in fabric bags that act as filters;
- The juice is squeezed out using drainage grates made of wood or using “pancakes” made of stainless steel.
The use of drainage grates or “pancakes” ensures that juice is squeezed not only from the upper and lower parts, but also from the middle part of the compressed volume. The bags, as mentioned above, act as filters and allow you to immediately clear the pulp from the squeezed juice.
In cases where performance hand press To obtain juice is not enough; electrically driven devices are used. An electric drive can be seen in a screw press for squeezing juice and in screw-type units that operate on the principle of a conventional meat grinder. In the first case, the press drive is a pair of “electric motor – hydraulic jack”.
In screw presses, which are structurally reminiscent of a conventional meat grinder, the drive electric motor is directly connected to the working element - the screw. This press is used for squeezing grapes; it is also an excellent press for fruits, berries and squeezing juice from tomatoes. It works according to the following principle: the loaded raw material is crushed by means of a screw and pressed through a sieve that has a conical shape. This form of the sieve allows not only high-quality extraction of juice, but also the removal of seeds. It should be borne in mind that grape or any other juice obtained from such a press has a large amount of pulp.
Prices for serial models of juice presses depend on several factors:
- loading basket volume;
- device type;
- material of manufacture;
- press productivity in terms of juice obtained per unit of time.
Naturally, the cheapest option is a small-capacity home press operating on a screw principle. The cost of a hydraulic juicer is slightly higher. Further on price category There is a press juicer for processing apples and other raw materials, operating using compressed air. The most expensive ones on the market today are membrane-type hydraulic presses.
DIY juice presses
It is quite possible to make a juice press with your own hands, the main thing is to find operating diagrams and drawings of such homemade products, which will not be difficult. Many of those home craftsmen who already have experience in making such equipment are happy to share photos of their devices and even videos showing the process of their manufacture and the principle of operation in detail.
Most often they try to make screw-type presses with their own hands. Meanwhile, it should be borne in mind that it will not be possible to make a powerful screw for such a device without the involvement of a qualified turner. It can be made without third-party specialists if you replace the screw mechanism with a conventional jack (mechanical or hydraulic), which is in the arsenal of every car enthusiast.
Main load-bearing element a press for squeezing juice made by yourself is a frame. Its strength should be given Special attention. To make a frame into which the jack will rest and create the required pressure, you can use a square metal pipe with a cross section of 40x40 and a wall thickness of at least 3 mm. When calculating the height of the frame of your homemade press, you should take into account the total thickness of the drainage grids, pads and bags of raw materials, as well as the height of the jack. The width of the frame can be chosen arbitrarily - the main thing is that a storage tray for collecting the squeezed juice is placed in the opening created.
When creating a press for apples or grapes with your own hands, you should pay special attention to its stability. For effective solution For this purpose, three pieces of square pipe can be welded to the bottom of the frame, which will serve as legs and ensure the stability of the unit. A stand made of boards or wood board on which the pallet will be placed.
Drainage grates, complete with which your apple, grape or any other press will work, should be made only from hardwood (oak or beech). The thickness of the planks from which such gratings will be made must be at least 20 mm.
The press basket is made of oak planks (you can buy parquet planks), tightened with corners with small gaps and secured with stainless steel screws.
The bags in which apple pulp or other raw materials for squeezing juice will be placed can be made from various fabrics (the main thing is that such fabric is different high strength and the bags that are sewn from it did not burst under the influence high pressure created by the jack). As such fabrics, in particular, you can use ordinary burlap, jute, cotton and linen fabrics, chintz and synthetic materials.
Today we will talk about how to make your own press for squeezing juice from fruits, berries and vegetables or homemade juicer with your own hands. We will also consider technologies and drawings homemade presses and juicers with clear illustrations
Exist various designs presses for squeezing juice. Basic homemade designs- these are screw or using a jack. A good option when using an air jack or a rubber bladder and a compressor. There are options for using a centrifuge, for example an old washing machine. Presses or juicers should not crush seeds and ridges located in the pulp.
Depending on the expected volume of processing of raw materials into juice or wine, select the design of the juice extraction device you like. In any case, the cooking process is divided into two stages: 1. Preparation of pulp (grinding raw materials); 2. The actual extraction itself is the extraction of juice.
Screw designs juice press
Typically a press consists of a pressing mechanism, a basket, a base and a pressing board. The basket serves as a receiver for the pulp and is installed on the base of the press. There is also a tray for draining juice. The bottom and side walls of the basket are lined with a whole piece of burlap without gaps. The ends of the fabric should hang over the edges of the basket. Then the pulp is loaded into the basket and covered with the ends of the burlap. Put on top wooden circle, onto which the press head is lowered.
Here is an example of another homemade juice press. The press consists of two pipe stands with a diameter of 22 mm. A U-shaped profile bent from 3 mm steel is welded to the pipes on top. The height of the profile is chosen in such a way that a screw nut pressed into a steel sleeve can be freely placed inside. A clamp is welded to the bottom of each rack. Using these two clamps, the press is attached to the window sill. A head with a hole for the handle is welded to the screw on one side, and a stop is attached to the other, which compresses the raw material.
A leaky 3-4 liter enamel pan is suitable for collecting the squeezed juice (Fig. a). You need to drill a hole in the bottom and attach a fitting with a hose to collect the juice.
The basket is made of stainless steel sheet 2 mm thick; bandage rings made of stainless wire with a diameter of 4 mm are welded to it on top and bottom. The rings allow the basket to fit “evenly” inside the pan. The walls of the pan are perforated with a drill with a diameter of 3 mm (in random order).
The spacers that separate portions of raw materials loaded into the basket consist of two 2-mm stainless steel disks connected by spot welding. Holes are drilled in the disks using a drill with a diameter of 3 mm, and gaskets 4 mm thick are provided between the disks (gaskets are also made of stainless steel). In general, all parts of the screw press are made of stainless steel; a tank from an old washing machine is quite suitable.
The work of squeezing juice occurs as follows. The body of the press is secured with clamps on the windowsill in the kitchen (you can also install the press on the table). The screw with the stop is unscrewed until it stops. A basket is placed in the pan, and a gasket is placed on the bottom of the latter and a napkin made of durable fabric is placed on it. Next, crushed raw materials (apples, fruits, herbs, berries) in an amount of 0.5...1 kg are placed on a napkin.
The napkin is folded into an envelope, the portion is covered with a drainage pad, on which another napkin is placed. There should be 3 such bags, and the top bag can rise 4...6 cm above the pan. Putting a gasket on the top bag, the pan is placed under the press screw. Yes, I completely forgot to mention the spacer (a circle of wood) that is placed under the basket (otherwise the pan may become unusable when the screw is tightened).
When creating pressure, the screw must be turned slowly and smoothly, monitoring the release of juice. Having finished squeezing the juice, unscrew the screw upward, transfer the pan to the table, and remove the pulp from the napkins. Depending on the type and quality of the raw material, in one cycle, using a homemade screw press for squeezing juice, it is possible to squeeze out 1.2...1.8 liters of juice, and in 1 hour - up to 12...15 liters.
Wedge press for squeezing fruit juice
It is necessary to arrange a wooden trestle on four legs B 1 m high. At the top these legs are connected by a thick (9-10 cm) board A, the width of which is 30 cm and the length is about 1 m. In the board we make a longitudinal slot D 10-12 cm wide and long 40 cm. Into this slot we insert two boards B (thickness 9-10 cm), hewn at the top and bottom. At the bottom, we tie both boards with an iron bracket or, even simpler, with a thick rope.
In order for the boards to hold and not fall into the slot, we pass iron pins or wooden bushings in their upper part. Then we make several wedges of different thicknesses from hard wood - and the press is ready. It works like this: spreading the boards B apart, inserting a bag of strong canvas filled with pulp between them. Then, driving wedges into the slot, we squeeze the boards. This way we compress the pulp tightly. The juice flows down into a placed tub or pot.
Making a simple juicer using the lever principle
We take two birch boards, the length of the main board is 1 m, width - 300 mm, thickness - 100 mm. The second board, which serves as a lever, is 1.5 m long, 170 mm wide and 20 mm thick. In the main board we make grooves for juice drainage (Fig. a) 10-15 mm deep and 300 mm long. We strengthen this board obliquely either on separate racks or on a special table. We attach a second lever board to it using a hinge and a spacer board. We got a lever press. We put 4-5 apples or some other fruits in the opening, press the lever, and the juice flows down the grooves into the placed container.
Nowadays, self-taught craftsmen are increasingly asking the question: “How to make a grape press with your own hands?” Grow grapes on your own garden plot simply put, the berry is unpretentious in care and grows quickly. Having built a press for it, you could store juice for the winter or cook your own Home wine.
A press with a twenty-liter basket is quite suitable for squeezing juice from overripe grapes for wine.
Option one.
What does the press consist of?
We will make a screw-type press and it will consist of:
Screw. It would be good if it was rectangular, powerful and threaded.
Basket. By the way, it can be made from parquet boards. Which then needs to be tightened with stainless steel hoops.
.
Advice:
And if suddenly your local market suddenly doesn’t have a strip of stainless metal of the thickness you need, in this case, grab some corners on the way home. After all, they can also be used to fasten parquet boards together.
The design of our press will be, so to speak, self-sufficient. That is, the finished press will be without stands, on legs. A nut will be attached to the top, and the screw rod will be screwed into it. There will be a basket in the frame itself; wort with pulp or grapes will be loaded into it
Let's make a basket.
We buy a couple of dozen parquet boards: length – 320 cm, width – 50 cm and 1.5 cm thick. We buy a metal strip, 1 mm thick. Many people buy metal corners made of stainless steel. In this case, you will need a couple of them, two meters each.
We remove the grooves from the boards using a cutter. Well, this operation can even be called useless if you have Dishwasher. Since in this case, with the help of its brush, everything is washed perfectly. But if there is no machine, so that the grooves do not become dirty, it is better to cut them off.
Now you will need stainless steel screws. We attach them to the corners, the gap is no more than 12 mm. Then, using a grinder, we cut a corner between the boards. We bend the edges. We make holes in them for the bolts.
An insert will be needed; its diameter corresponds to the diameter of the basket. The piston is placed on the grape pulp.
The height of the basket is 32 cm. The diameter inside is 29 cm. The estimated volume is 21 liters exactly.
So, let's continue the topic of how to make a grape press.
Now you need to buy:
Corners 25 mm;
Drills, diameter 6.2 mm;
Several M6 bolts;
Nuts to bolts.
Assembling the frame of the press.
Please note that it is necessary (!!!) to place boards under the screw, on top of the circle.
The screw can be ordered from a turner, or you can build it yourself if you have the appropriate skills.
Screw parameters: diameter – 30 mm, pitch – 3 mm, nut, disk with holes for fastening, welded.
More details:
A small piece of plywood as a stand for the press;
Plastic bowl. We make a hole in it, put a tube in the hole.
Of course, you can do everything using welding machine, but if there is none, and if there is no experience working with this device, then the question immediately arises of how to make a grape press without welding. This is where the idea came to mind, to make a press with bolts.
You can safely cook parts using inventory, right in your apartment on the balcony.
Design flaw.
Option two.
Step one.
In order to squeeze juice from grapes right at home, to make jelly, juice, wine and other things, you will need a press. We will now tell you how to make a grape press.
You need a roller crusher. You can also make it yourself, for example, from a loading ladle. The berries will be poured into this crusher. It's better to build it from wooden frame. To the frame we add a pair of rollers, also made of wood, and a handle for rotation. We secure all elements with bearings.
Step two.
We prepare all the details. We make a frame from bars: length - 70 cm, cross-section - 4 by 10 cm. Width of the frame - look at the length of the rollers, since the width completely depends on how long your rollers will be. The optimal size is 20 cm. When constructing the structure, make sure that the distance between the blocks is the same.
Step three.
For the press, the rolls must be made corrugated, 3 cm deep. The corrugation can be made screw, in this case, we direct the shift to the side by a couple of cm. Next, we attach the rolls to the frame with bearings. They will spin on different axes and at different speeds.
Step four.
If the diameter of the wool is the same, it is necessary to make the rollers have different diameters. What does this give? The speed of movement in a circle will be different. For such a press you need wooden ladle, where the grapes will be loaded. Choose a pyramid shape.
Step five.
We place the bucket on the frame slats. Our slats should be transverse. The distance between the bucket and the roller is minimal, preferably no more than a centimeter. Ready. It's time to secure the crank for rotation. With its help, the grinding of raw materials and pressure of juice will be carried out.
Step six.
At the bottom of the structure we place a vessel to collect the juice.
We load the berries into a ladle, from there they fall onto the windrows. We rotate the handle, the berries are crushed and crushed until you get a puree.
Step seven.
We remove the berries from the bunch. Rinse thoroughly under running water. And only then load it into the press. And when the juice is ready, rinse the press with water and dry it with a soft towel or napkin. If you don't take care of it properly, the wood will simply begin to rot.
