Garden press for apples. Making an apple press with your own hands. The simplest frame press with a worm mechanism

A large apple harvest sometimes becomes a problem for owners. The fruits cannot be stored for a long time; it is not always possible to sell them or prepare them for animal feed. The way out of the situation is homemade preparations in the form of jam and juices. It will be easier to prepare them if you use juicers and special homemade apple presses.

Juice presses are:

Mechanical,
Hydraulic,
Pneumatic,
Electrohydraulic.

Purchased models, regardless of type, cannot cope with large volumes of fruit.

Therefore, most gardeners prefer to make a household apple press with their own hands.

Each type has its pros and cons. Mechanical is less productive, but the easiest to manufacture. Hydraulic ones have a more complex mechanism, but are capable of producing high-quality fruit puree. A pneumatic device requires a compressor, this affects the price of the device. But it is capable of processing a large volume of fruit in a short time.

The most effective are electro-hydraulic models.

They operate on a combination of electricity and hydraulics. A person's job is only to serve fruit. The disadvantage of the device is the high cost of spare parts.

Most models provide pressure on the apple mass from above, but the combined version has its own differences:

The screw device presses the mass from top to bottom,
Hydraulic jack - from bottom to top.

To make a juice press you need to consider the following points:

Juice container. You can use a tank or a large pan, and install a tap at the bottom to drain,
If used wooden barrel, then it should be made of parquet slats,
If a housing is used washing machine, then it must be clean and sealed, free of rust and mold,
Apparatus body. The simplest option is a pyramid of wooden latticework.

To ensure uniform extraction of juice, finely chopped fruits are placed in clean bags, or transferred soft cloth. If this is not done, the DIY juice press will leave wet pulp and a large number of waste. You can cut apples using an ordinary knife or a special chopper. The device can be purchased, but more often it is made independently and built into the pressing apparatus.

Homemade screw press

A properly assembled press can squeeze up to 70% of the juice from apples. The output remains dry pulp. The screw apparatus works by rotating large blades secured with nuts or jacks. The design of the hydraulic jack is different greater productivity and does not require the use of large physical strength. Before making a press you need to prepare:

Stanin,
Housing for storing raw materials,
Wooden gratings,
Pressure piston
Circle under the jack,
Work unit,
Tray or bowl.

For production, two are taken metal pipes, to which the profile is welded. Most often it is made in the form of a crossbar. A small hole is made in it, to which a threaded head is welded for installing a screw. A clamp is welded to the pipes or supporting structure. A handle for rotation is installed on top of the screw, and a stop at the bottom. It is a wooden or metal circle. Wooden body It is made of boards about 5 mm thick, they are tightened with self-tapping screws with an anti-corrosion coating. The distance between the yards should not exceed 1 cm. The strips with the yards are bent in the form of a circle and fastened with bolts. A plastic basin with a hole for draining juice is used as a tray.

Option using a jack

It is more convenient to use jacks for cars weighing 2-3 thousand kg instead of a screw. A nut for fastening is no longer required here, and a homemade press from a jack turns out to be more powerful. The only difference in the assembly is a durable frame that can withstand pressure. The jack is installed both from below and from above - it depends on the user’s preferences.

When the apparatus is ready, apples are placed in the container and a wooden circle is placed underneath. This will maintain the integrity of the structure at high pressure.

Average productivity - 1.75 liters of juice in 5 minutes.

How to make a hydraulic press

To make it you will need:

Grinder machine,
Welding machine,
Capacity 50-60 l,
Drill,
Metal pipes with a wall thickness of 0.3 cm,
Hydropress,
Sturdy oak yards.

How to do Hydraulic Press: a hole is drilled at the bottom of the tank and a tap is installed to drain the juice. The container is inserted into a barrel assembled from boards or slats. The distance between them should not be less than 0.3 cm. It is recommended to fasten the barrel with galvanized steel. If a barrel without a casing is used, then it is placed on a pallet. It has a hole for draining juice.

The base - the metal frame - must be strong, since it bears the main pressure. It is made according to the same principle as for a screw press. A DIY hydraulic press will become more stable if you weld 2-3 metal pipe sections to the bottom of the frame.

A circle made of wood can serve as a piston. The diameter should be slightly smaller than that of the juice container. It is made from two oak boards fastened with self-tapping screws. A circle of the same diameter made of stainless metal is usually used as a stop. A hydraulic device is installed on the stop.

An elastic barrel can also be used as a press. It connects to the water supply and will expand under the pressure of water. The press presses on the apples, resulting in the release of juice.

Homemade screw press

A screw press resembles a meat grinder. It works from electric motor, which rotates the pulley using a belt drive. Raw materials are loaded into the feed chamber, the auger crushes it and presses it through a sieve. At the output, the screw press produces juice with pulp.

For homemade this is the most difficult option. To assemble it, you will need drawings and diagrams, as well as:

Durable housing made of of stainless steel,
Screw press, which is placed inside the housing,
Capacity for receiving raw materials,
Container for prepared juice,
Electric motor giving from 1500 rpm.

The structure is assembled on a metal frame. As a housing, you can use a housing from a conventional or electric meat grinder. A screw press is installed in it, which is attached to the engine using a drive. A sieve with the desired cell diameter is mounted on the outlet. You can use jars, pans or basins as containers for the finished juice.

The screw press has greater productivity because it is driven not by manual force, but by an electric motor.

The performance of such a machine is up to 7 liters of juice in 5 minutes.

If you have experience making presses for apples and other fruits, share it in the comments to the article!

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".

Installations designed for squeezing juice are divided into mechanical, hydraulic, electro-hydraulic and pneumatic.

The most common mechanism is 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, they use hard wood beech 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 method of squeezing 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 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. Screw piston replaced by rubber diaphragm

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.

Screw press - a relative of a 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 apple juice can be bought for 34,000 rubles. For a membrane-type hydraulic device, sellers are asking 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 selected 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 with bolted joints, using a powerful angle and a profile pipe.

For the bottom base plate A piece of laminated chipboard countertop was used.

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

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. Actually the extraction itself is getting juice.

Screw structures of the press for squeezing juice

Typically a press consists of a pressing mechanism, a basket, a base and a pressing board. The basket serves as a pulp receiver and is installed on the base of the press. There is also a tray for flowing juice. Bottom and side walls the baskets 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. A wooden circle is placed on top, onto which the press head is lowered.

Frame screw press. Device: 1. Packages with crushed raw materials; 2. Screw; 3. Bed; 4 Drainage grates; 5. Juice drainage chute

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 the screw nut pressed into the steel bushing is 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 a handle is welded to the screw on one side, and on the other, a stop is attached, which compresses the raw material.

1 - clamp; 2 - stand pipe; 3 - crossbar; 4 - screw; 5 - emphasis; 6 - table; 7 - bushing with a pressed nut.

To collect the squeezed juice, a leaky 3-4 liter enamel pan is suitable (Fig. a). It is necessary to drill a hole in the bottom and fix a fitting with a hose in it to collect the juice.
The basket (fig. b) is made of stainless steel sheet 2 mm thick, bandages-rings made of stainless wire with a diameter of 4 mm are welded to it from above and below. 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 into 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.

For getting good harvest-, as well as growing strawberries at home. The work of squeezing the juice is 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 to the stop. 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 fruit juice press

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. We make a longitudinal slot D in the board, 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. Thus, the pulp is strongly compressed. The juice flows down into the substituted tub or pot.

Making a simple lever juicer

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 (Fig.b). Got 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.

" 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 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.

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 wooden version using ordinary gardening tools .

For the manufacture of home press The tools you will need are a hacksaw for wood and metal (or a grinder), welding machine, screwdrivers, pliers, hammer. As for materials, the following are mainly used:

metal channel;
wooden blocks, slats, boards;
self-tapping screws, bolts and nuts;
tank or barrel, stainless steel sheet;
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 solid foundation and working mechanism.

The principle of operation 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 descends 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.
Based on the jack: 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 lattices, 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 axle) with a nut or a mechanical jack. The latter option is much simpler - you can buy it in a spare parts store or get it out of the trunk of a car, you don’t need to look for anything, adjust, grind and weld.

Designs based on a hydraulic jack are much more productive(force from 1t) than mechanical ones, and require a minimum of labor costs on the part of a person. Bottle hydraulic 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 retainer for the pressure part of the screw is attached to the top board - any metal part of a suitable shape (can be mounted 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 a press.

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 the wooden barrel is not completely airtight, that’s 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 a support out of a stainless steel sheet.

Drainage pads are made in the same way as in the description for the screw press, but they are given a round shape.

As a result, the design should be something like in the photo.

Preparation of raw materials

The principle of pressing apple juice simple - the finer the raw material is chopped, the more product will be the output. 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. A suitable crusher can also be made independently.

The simplest design of a homemade crusher

A deep hopper is mounted lightly on the cone from moisture-resistant plywood or stainless steel sheet. Two bars are attached to it for stability from below. A wooden roller (preferably made of beech) with self-tapping screws wound in a spiral is cut into the lower part of the container. As a drum, you can use an ordinary kitchen rolling pin. The axis of rotation of the roller comes out, a drill is inserted into it and the process begins.

Some simply crush apples in a bucket with a construction mixer.

The process of squeezing juice from apples at home

After the raw material is prepared, it 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!

After the summer struggle for the harvest comes autumn struggle with the harvest. A juice press is a device that can greatly simplify this task. It is used both in summer cottages and in industrial purposes. Has several configuration options. You can even create a simple device with your own hands. IN different regions In Russia it is most often used for collecting apples, grapes, carrots, and other vegetables and fruits.

How does a juice press work?

The device has a mechanical control type. Comprises:

Baskets for loading vegetables or fruits. Depending on the model, it can be made of metal or wood.
Press. It descends into the basket and squeezes its contents.
A filter through which the squeezed product passes, leaving behind pulp, seeds, etc. It can be made of burlap and wooden grates.
The tray into which the finished product flows out. Made from different materials, right down to the plastic.

If the juice press is manually operated, it takes a lot of effort to extract the juice. Especially when it comes to vegetables, herbaceous plants or hard fruits(). Therefore, it is better not to consider it as a gift for a woman. Only if you need a small volume for kitchen use.

How the device works:

Before starting work, the products from which it is planned to make juice are cut into small pieces (or crushed).
They are placed in a basket, distributing evenly over the entire plane (some devices use a special filter bag).
Gradually a press is lowered onto the basket, compressing the contents.
The drink is cleaned by passing through filters and ending up in the tray.

This principle is called the cold press method.

The press does not heat the products, thereby preserving everything useful material, which were laid down by nature.

Advantages and disadvantages

What are the advantages of this type of food processing:

all vitamins and minerals are preserved;
the minimum amount of waste is only 5%;
does not make noise when used;
simple design, easy to repair in case of breakdown;
long-term operation without wasting resources;
is inexpensive;
can be easily transported from place to place.

Minuses:

if the volume of products is large, then spinning will require a lot of effort and time;
you have to pre-process vegetables and fruits (for small models, in addition to cutting, you also need to peel the fruits and remove the seeds);
You can’t get a lot of juice from one serving of the product.

Before choosing, you need to decide on the criteria by which you need to evaluate the device.

Types of control of juice presses

Manual presses require direct human participation in the spinning process. Automatic devices take effect after pressing the button. The latter include hydraulic or pneumatic presses. Their purpose is to process a large volume of products; they are most often used on farms where food is collected. big harvest or in production workshops.

For ordinary suburban area an automatic press for squeezing juice is not suitable, since there is no large volume and the cost of the device is above average (about 500,000 rubles).

Types of presses

They differ in the type of mechanism and the nuances of device assembly. Mechanically controlled presses have a small production volume, up to 30 liters per hour. The units are simple, you can make them yourself. Well suited for use at home and in the country. The main structural element is a steel frame. It holds the device in place during use.

Manual screw press

This device is the simplest and very convenient. A screw press for squeezing juice has a simple design: it is driven by a screw. Under its influence, the piston lowers. Such units are inexpensive. The only negative is that they sometimes require considerable physical strength.

Models calculated hand press about 2.5 liters of vegetables or fruits.

Juice jack press

It is easier to control than a screw. Fix the device on the floor and set it in motion using a jack. Physically, this is much simpler than tightening a screw. It can be used in the country, right on the street. A jacking press costs approximately 15,000 rubles and can produce up to 3 liters of juice per full load.

Pneumatic press

Works in automatic mode. It is set in motion by the action of compressed air, which is created by a compressor. It is advisable to use it on large farms, farms or on several plots. Capable of processing large quantities of vegetables and fruits. Its price is approximately 80-90000.

The pneumatic press produces up to 14 liters of finished juice in 1 cycle.

Hydraulic

Looks like a metal basket with holes. Inside there is a rubber bag into which water is supplied under pressure. The bag fills and presses on the raw materials that are in the basket. The juice flows through the holes into the lower reservoir.

There are mechanical, automatic and electric models. The device is set in motion by fluid pressure on the piston. And it is created using controls.

There are two types of hydraulic juice presses:

Due to the complex design of the hydraulic press, its price is above average. In private households it is used less often than screw.

Belt press for juice extraction

Used in factory production. Fully automatic, performs all functions independently. The machine is powered by electricity and produces directly pressed juice.

Combined

Here the screw and jack are tried on together. Initially, the juice is produced using a screw mechanism. Afterwards, the remains are pressed down with a jack. Effective on garden plots small size, convenient and easy to use.

Differences by type of raw material

In most cases, juice presses are universal. You can squeeze any fruits and vegetables in them. Some models involve the creation of oil.

A special press is only suitable for a certain type of raw material. For example, it is used only for citrus fruits or berries. It is not recommended for use on hard products.

How to choose a juice press

For a home or a small company, a press with a volume of 3-5 liters is enough. There are special small devices with which you can prepare 1-2 glasses of juice. To give, when you want to roll up several cans of juice, use a screw or hydraulic press with a volume of 10-12 liters.

If there is a large garden, wine is produced or a press is used for apples in a large farm, you need to take a volume of up to 30 liters. Automatic or semi-automatic control. Small industrial production will require the ability to squeeze up to 200 liters of juice per hour. A pneumatic press for squeezing juice or an electric belt press is ideal here.

The harder the raw material, the more powerful the unit will be required. For juice from apples and grapes, a screw press can be used, but processing will take a long time. A hydraulic apparatus will produce more juice than a screw one.

Used to chop fruits and vegetables special devices- shredders. Any press can process whole fruits and vegetables, but the quality will be much worse, so this is not recommended.
