Owners of orchards, vineyards and berry plantations The problem of crop processing is well known. 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. For home craftsmen, information about the features of making a powerful “juicer” on your own will be useful.
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 juice press 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 a 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 pressure 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.

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. By crushing the raw material, the auger forces it through a sieve and produces juice with a large amount of 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.
The average price of home “juice squeezers” driven by a 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 squeeze press with your own hands as stable as possible, three pieces of square pipe (length 15-20 cm) must 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 be made only from natural wood (oak, beech). The thickness of the drainage grid boards must be at least 20 mm.
To sew bags, you can use different fabrics (jute burlap, linen, 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 on bolted connections using a powerful angle and 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, since particle boards contain toxic phenol-formaldehyde adhesive.
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
If you don't have electric juicer, you can quickly and easily process a large apple harvest into juice using a press. If you have basic skills in working with tools such as an angle grinder and welding machine, making an apple press with your own hands at home will not be difficult.
For the press you will need:
How to make an apple press with your own hands from scrap materials
We will give the sequence of assembling an apple press from materials that were, as they say, at hand. We’ll also tell you about the principle of operation. You can select or change the materials for making the press based on your capabilities.
Frame
We will assemble the frame using an angle grinder and a welding machine from an old channel.
Such a channel is usually used for scrap metal. We will clean it with sandpaper from rust and weld the structure: perpendicular to each 70 cm long leg, we will weld a 60 cm long channel in the middle. We will connect the channel along the top with a 40 cm channel, and at the bottom we will weld 46 cm on both sides of the channel. A hole is cut out on the upper channel. The diameter depends on the diameter of the screw. Our screw, as mentioned above, is from an old workbench. The larger the diameter of the screw, the better (ours is 25 mm). Then we place a ball from the bearing under the screw to reduce friction. We get this basis:
Stand
We make a stand from wooden blocks - a square with a side of 35 cm and a height of 10 cm. The lattice is made of two layers of boards - one layer perpendicular to the other, thickness 10 mm - 30 cm by 30 cm.
Tray
For juice you need to make a tray - a sheet of metal made of stainless steel. For convenience, you can bend the spout on the sheet. Place a pan under this spout. In the photo - old aluminum pan, the first one that came to hand. It is not recommended to use metal utensils for apple juice; it is better to replace them with plastic ones.
Next, we make a shape for the scarf: a square 25 cm and a thickness of 6 cm. Insert a fabric scarf 50 by 50 cm into the frame, where we place the prepared apples (cake), fold the edges into an envelope and place it in the mold. Then the mold is removed and the second lattice is placed on top. A mold with grated apples, etc. is placed on it. The quantity depends on the height of the press. We substitute the pan. We start turning the screw clockwise and get apple juice.
We prepare the apples as follows: wash them, cut them, grind them on a grain grinder or pass them through a vegetable cutter. To facilitate labor, a factory-type manual feed cutter was mechanized. Converted into a mechanical one, the drive and motor were taken from an old washing machine.
To enhance the juice extraction, an additional pipe was used, which was inserted into the screw handle. Thus, the press squeezes the cake until dry. Instead of a screw, you can use an automatic jack for 2-5 tons.
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 bother 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.
What materials will be needed
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 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.
Homemade press designs differ in the operating principle of the main mechanism:
- Screw.
- Jack based: mechanical and hydraulic.
- Combined.
In the bulk of structures, the pressure is from above, but in the combined version, compression occurs in two directions: using a screw mechanism at the top and a hydraulic jack at 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 a mechanical jack. Last option 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- 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 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
The principle of squeezing 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
A deep hopper is mounted lightly on the cone from moisture-resistant plywood or stainless steel sheet. 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!

TaggedIf you don’t have an electric juicer, you can quickly and easily process a large apple harvest, for example, into juice using a press.
This problem also arises among winemakers, among whom there are no people willing to process the berries manually. It is quite possible to make a juice press yourself, eliminating additional expenses for purchasing equipment, which is quite expensive today. Operating principle of a juice press
Manual type screw juicers can be made according to different technologies, in the process of this, parts are used like old containers, tanks from washing machines, as well as pots and planks.
In some cases, structures are made using a jack.
Homemade press for juice
Simple press for squeezing juice - do it yourself
There are various juice press designs. 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 Juice Press Designs
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.

Design screw juice press is clear from the pictures. 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.
1 - clamp; 2 - stand pipe; 3 - crossbar; 4 - screw; 5 - emphasis; 6 - table; 7 - bushing with a pressed nut.
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 secure a fitting with a hose in it to collect the juice.
The basket (Fig. b) is made of stainless steel sheet 2 mm thick, with bandage rings made of stainless wire with a diameter of 4 mm. 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).
Gaskets (Fig. c), which 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 (the 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. To obtain good harvest-, as well as growing strawberries at home. 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.
Processing the harvest of berries and fruits is one of the most important tasks that not only farmers, but also owners have to solve personal plots. 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.
Most common due to low cost and the simplicity of its design is a manual type mechanical press. 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.
To make a basket into which raw materials for squeezing juice are loaded, sheet metal can be used. stainless steel or hardwood (such as 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 the water filling it, but under the pressure of compressed air supplied from the compressor.
Because the individual species The raw materials from which the juice must be extracted are loaded into presses in crushed form; it is necessary 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 stainless steel “pancakes”.
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 the productivity of a hand press for obtaining 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 that will not cost special labor. 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.
The main supporting element of a homemade juice press is the 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. On top part legs, a stand made of boards or wood boards is placed 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 highly durable and the bags that are sewn from it do not tear under the influence of 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.
