In autumn, the moment comes when winemakers get to work. To process a large number of grapes, you will need a special crusher. This device is used both in large production and in a private winery. After all, it saves not only time, but also energy. In this article, we will understand what a crusher is, how it works and the criteria for choosing it.

Purpose and description of the device

In the modern world, where they try to automate all work, it is not advisable to use primitive manufacturing methods. Crushers are used to make grape juice.
They are designed to grind berries and form a mixture for further distillation of wine. These devices are used for processing grapes both on an industrial scale and at home.

The grinder has a fairly simple but effective design. The simplest device consists of a loading hopper, at the bottom of which there are two parallel rollers. The bunker is mounted on a wooden frame, and the rollers rotate using a system of gears and a handle.

Some designs may also have a container for crushed berries. Although you can use a wooden vat or a plastic barrel.

How a crusher works

After harvest, the grapes must be processed as soon as possible. Berries are poured into the loading hopper. The grinding rollers are located at some distance. Thus, when the grapes fall between them, the berries are crushed, and the seeds remain intact.

Important! If the gap between the rollers is minimal, then there is a chance of crushing the grape seed. In this case, the tannins contained in it will get into the juice or wine and give them bitterness and viscosity.

By turning the handle, the rollers begin to move. The gear system is designed in such a way that when set in motion, the rollers rotate in different directions. Grapes that fall between them are crushed.

Their skin bursts and the pulp with juice is released, and the rotation of the rollers pushes them into the pulp vat.

Types and selection criteria

For large volumes, using a manual crusher will be impractical. Therefore, let's figure out what types of crushers are and the criteria for their selection.

Mechanical and electrical

Mechanical or manual, as it is also called, is widely used for home production or in industrial production of small volumes. Servicing such an installation is necessary in pairs.

So, one person rotates the handle, starting the mechanism, and the other fills the hopper.

How quickly the grapes will be processed using such a crusher depends on the effort applied to the lever, as well as the speed of loading the hopper. Most often they are used for crushing grapes with a volume of not more than 500 kg.
Unlike mechanical ones, electric ones are more convenient to use and can be serviced by one person. According to the principle of operation, they are identical, and differ only in the use of an electric motor that starts the crushing mechanism.

The advantage of such an installation is uniform crushing.

Electric crushers vary in grape processing capacity. So, there are crushers with a capacity of 500 kg / h, 700 kg / h, 1500 kg / h and 2000-2300 kg / h, which are used in small production.

The device, whose productivity does not exceed 500 kg / h, can be used in home wine production. In large wine production companies, crushing plants with a capacity of 10-15 t/h and even 40-70 t/h are used.
The power of crushing devices with an electric drive is on average 0.75 kW for a capacity of up to 2000 kg/h and 1.5 kW for processing grapes with a volume of 2000-2300 kg/h.

Types of grinders

Crushers according to their design are divided into roller and centrifugal. Rollers are most widely used, as they meet the technological requirements for the manufacture of raw materials for wines to the maximum.

The principle of operation of such shredders is based on the use of two or more rolls of various shapes. Corrugated, lobed or smooth shapes are mainly used. The use of this type of crusher allows you to get a high quality wort.

The centrifugal crusher uses a high speed rotor. In this case, the grape berries are crushed as a result of the impacts of the rotor.
Using a crusher allows you to get the maximum amount of dyes. With its help, the must is made from red grapes.

Production material

The modern market offers a variety of crushers that differ in shape, size, performance and, of course, material. So, depending on the material used, crushing plants are made of wood, plastic and made of painted or stainless steel.

Important! The main requirement for the material from which the crusher is made is resistance to oxidation, since grape juice is characterized by high acidity.

The most common for home production is a wooden chopper. And for production, entrepreneurs most often choose stainless steel crushers, which are presented in a large assortment.

Download type

On the modern market there are shredders with various types of loading. There are designs with vertical and horizontal loading hopper.

Most often, these types of loading relate to a centrifugal crusher, or, as it is also called, CCH. Roll shredders are produced with a vertical type of loading.

Device size and weight

Various designs of shredders are offered for sale, which also differ in their dimensions.

Manufacturers offer mechanical crushers of various designs, but their dimensions are clearly standardized.
For example, a chopper with a loading hopper of 15 kg and dimensions of 650 * 470 mm has dimensions of 1000 * 390 * 490 mm and a weight of 18 kg, a chopper with a comb separator for the same volume of the hopper has a weight of 35 kg and dimensions of 1120 * 460 * 580 mm with bunker dimensions in 460*760 mm.

A mechanical crusher with a hopper of 25 kg and dimensions of 1000 * 630 mm has a weight of 29 kg and dimensions of 1210 * 620 * 400 mm, and the same chopper with a comb separator will have dimensions of 1210 * 520 * 690 mm, weight of 40 kg and a hopper size of 1000 * 500 mm.

Electric crushers also come in different sizes:

• the shredder with a capacity of 1200-1500 kg/h has dimensions of 1210*600*690 mm and a weight of 51 kg;
• chopper, processing up to 2000 kg/h, weighs 50 kg, and its dimensions are 1330*570*610 mm;
• crusher with a capacity of 2000-2300 kg / h has dimensions of 1180 * 680 * 900 mm and weighs 94 kg.

The presence of a destemmer

The taste of juice or future wine depends on the amount of tannins that it contains. They can get into the composition of the pulp when the bones are crushed or when the grape ridges are crushed.

Since the ridges ripen longer than grape berries, they contain a large amount of tannins. If they are not removed, then the wine will be more tart, and with a high content of them, it may even be bitter. To eliminate them, grinders with a comb separator are used.

The principle of operation of such crushers is to use an additional shaft, when passing through which the ridges are separated from the berries. The berries go for further processing to a pair of crushing shafts, and the ridges fall into a separate container.

Grinders of this type are used in the production of white wines. When separating the stems, it is also necessary to take into account the variety of the future wine and the grapes used.
For example, in the production of Bordeaux, only ¾ of the stems are removed from Verdot grapes, and ½ from Merlot and Malbec grapes.

Did you know? In the production of red and white wines in Argentina and Chile, crushers without destemmers are used, and since the stems are not separated, the difference between these wines differs only in the period of pulp fermentation.

In the production of muscat wines, it will not work to use a crusher with a destemmer, since the grapes are harvested when the berries are already raisined and withered, and it is difficult to separate the ridges from such berries.

How to make a simple do-it-yourself grape crusher

In order to assemble a grape chopper, you will need the following items:

• loading capacity;
• plywood case;
• rollers - 2 pcs.;
• gears - 2 pcs.;
• washers - 2 pcs.;
• metal frame;
• pen.

The loading tank is made of stainless steel, it is shaped like a cut trapezoid. For the manufacture of the bunker, steel with a thickness of 1 mm is used.

The body is made of plywood 12 mm thick, and its size depends on the size of the rollers that will be placed in it.

Plywood is fixed in such a way that one side is removable. For example, the side where the handle and gear system will be attached. The removable side allows you to easily disassemble and wash the crusher after use.

The roller drive is located inside the plywood case. They are made from glued plywood, which is turned on a machine, mounted on a 12 mm axis and sits on glue. In order for the rollers to have the shape of gears, grooves must be made on them. The diameter of the rollers is 80 mm, and their length depends on the maximum possible size that the lathe can clamp.

Install them in such a way that the gap between them is 3 mm. With this arrangement of shafts, the grape seed will remain intact. After fixing the rollers in the frame from the outside, two washers are installed on the axles, and on top of them - two gears with a diameter of 85 mm.

On one of the gears is attached a handle made of an iron pipe measuring 15 * 15 mm. For ease of use, a tube is used as a handle, which will rotate around its axis.

The crusher body is mounted on a frame of 15*15 mm pipes connected by 20*2 mm steel strips. The metal frame is made in such a way that the crusher can be installed on the pulp container.
All wooden parts of the crusher are varnished in 3 layers to protect against caustic grape juice. Such a simple design of the crusher is useful in the economy of any novice winemaker.

What can replace the crusher for grapes

In the production of wine, the use of a grape crusher not only speeds up, but also facilitates the process of creating pulp. However, not every winemaker, especially a beginner, can afford to buy such a chopper, because the price of the cheapest device starts from UAH 7,000.

In this regard, let's look at other ways in which you can crush grapes and create a pulp.

The easiest option is to chop the grapes with your hands, especially if the amount is small. But if you have a large amount of grapes, then it will take you almost the whole day.
You can use the method of Adriano Celentano from the movie "The Taming of the Shrew", but in our latitudes autumn days are rainy and cold, and trampling grapes with bare feet can adversely affect your health.

There is a faster way to crush grapes without harm to health. To do this, you need to buy a new construction whisk. Using a whisk made on the basis of steel rods will easily and effectively break grape berries, while grinding the seeds will not.

To crush grapes in this way, pour a small amount of grapes into a bucket and beat with a whisk. In 2-3 minutes you will get the finished pulp. Using this method of crushing grapes is also convenient because after crushing it, you can easily remove a certain amount of scallops.
But this will have to be done manually. The prepared pulp is poured into a container where it will stand for the duration of fermentation.

A grape crusher is a quick and convenient way to harvest the pulp in the wine making process. The use of various designs allows you to process a large number of grapes and regulate the content of tannins in the future drink.

Now you know what are the criteria for choosing crushers and how to make such a product at home. Happy winemaking!

There are many nuances in home winemaking, without which it is difficult to get a good quality drink. In addition, the process of making wine is quite laborious. Experienced winemakers, who process a large number of crops per season, make various devices to facilitate their own work. From this article we will learn how a do-it-yourself grape crusher is made.

Purpose and principle of operation

Crusher for grapes- a device with a simple mechanism designed for processing berries. The design consists of a loading hopper, a tank for collecting cake and two parallel crushing rollers. Crushers for grapes are used both in the production of wine on an industrial scale, and in home winemaking.

The grapes intended for processing are poured into the loading hopper and crushed by means of crushing rollers driven in motion. The drive can be mechanical or electric. Processed raw materials are dumped from the pulp collection tank.

An important feature of the crusher for grapes is the presence of a gap between the crushing rollers. This allows you to leave intact grape seeds, which in a crushed state affect the taste of the finished product. The tannins contained in the pits add bitterness to the wine.

Varieties of grape crushers

Crushers are available with and without a destemmer. A grape crusher with a destemmer allows processing of raw materials many times faster, because the berries do not need to be picked off the branches.

Shaft crushers- this is the most commonly used type of crushers both in production and at home. The principle of operation is based on the opposite movement of two or more cylindrical shafts.

Impact centrifugal crushers can be horizontal or vertical. The principle of operation is based on the rotation of the rotor at a speed of up to 500 rpm. From his blows, the grapes are crushed.

Mechanical and electrical crushers can have exactly the same principle of operation. The difference lies only in the presence or absence of an electric drive.

How to make your own crusher

It does not make sense to purchase a factory crusher for grapes if you need to process your own crop. A fairly technological design can be done independently. The production of the unit will not require much time and serious economic costs, and the effectiveness of grape processing will not be inferior to factory equipment.

You need to start with the manufacture of the bunker. You can use any material for it, but it is preferable to take oak boards. If the tree was not at hand, we use stainless steel or plastic. The shape of the bunker is an inverted truncated pyramid.

Rollers can be taken from an old activator-type washing machine that was used to wring clothes. On the rollers we draw 6 longitudinal lines around the entire circumference. We drill holes along the length of each line at a distance of 0.5 cm. The diameter of the holes is approximately 10 mm, the depth is 0.5 cm.

In order for the rollers to rotate in the opposite direction, pulling the berries inward, you will need 2 gears. They can be removed from any mechanism or ordered from a turning shop. The main thing is that they are the same.

Now you need to make a wooden frame on which the rollers will be fixed. For the frame you will need a bar with a section of 50x50 mm. The length of the frame should be equal to the length of the rollers. The rollers are fixed at a distance of 2-3 mm on the axis in the center of the frame. The gear system is installed from the outside.

Now you need to assemble the structure. A frame with rollers is attached to a container for collecting pulp, and a bin for receiving grapes is installed on it. The handle for setting the structure in motion is mounted on one of the axes of the rollers. The simplest do-it-yourself grape processing device is ready for use.

On the basis of such a device, it is possible to manufacture a more advanced unit with an electric drive. We need an engine, you can take it from the same unnecessary washing machine, a shaft and a transmission belt. Instead of a handle, an electric control with a belt drive is mounted.

To speed up the process of processing grapes, you can install a destemmer on the fixture. For a destemmer, you will need a stainless steel mesh with 10-12 mm cells and an additional shaft with blades. The blades are made of stainless steel in the form of small blades and are welded in a spiral shaft. Berries, falling into the crusher with the help of this shaft, are separated from the ridges and enter the roller system for further pressure. The ridges remaining on the grid are dropped into an additional compartment.

Grapes are a popular crop among gardeners. A tall vine with dense greenery is often used as a shelter for a gazebo or recreation area. And when the formed clusters ripen, you can additionally receive aesthetic pleasure. It is not even worth mentioning the benefits of berries, the clusters are enriched with a large amount of minerals and vitamins that are valuable for the human body.

Why you need a grape crusher

Many summer residents grow grapes for home winemaking. The processing of berries includes the extraction of juice and the separation of cake. Manual work can only be done with small volumes. More thrifty gardeners use special crushers for this purpose. They can be purchased pre-assembled or made by hand. For self-assembly, you will first need to study the types of construction and the principles of operation of the mechanism.

Types of crushers and the principle of operation

All crushers are divided into mechanical and electrical. The principle of operation of electrically powered equipment is practically the same as the manual type design. The peculiarity of productive units is the presence of a destemmer, with the help of which the grapes are quickly and efficiently separated from the twig. Only pure juice and grapes enter the crushing compartment.

The simplest design is considered to be a wooden crusher, equipped with shafts, a container for juice, separately for cake and a handle, the rotation of which drives the mechanism. This option is available with and without a comb separator.

Roll crushers have a more complex device, which makes it possible to obtain high quality wort. The principle of operation is based on the rotation of the rolls in different directions. The distance between the moving parts is adjustable, this allows you to adjust the equipment for certain varieties of berries. The surface of the working elements can be smooth, embossed or lobed. Often preference is given to profiled rolls. The destemmer speeds up the process of grape processing, separating the berries from the stem with high quality.

Shock-centrifugal structures work with the help of shock and rotational movements of the mechanism. Under the influence of the impacts of the rotor, which at the same time rotates at a high speed (300-500 rpm), the berries are processed. This form of crushing guarantees a high quality must with a high content of natural pigments. In equipment of this type, the destemmer is an indispensable element.

Advantages and disadvantages

To assess the need and usefulness of a grape crusher, it is recommended to familiarize yourself with the advantageous qualities of the equipment:

Obtaining high-quality pulp that does not contain a large amount of components foreign to the product;

Rational use of time and effort;

Simple and durable design, which can be infinitely improved;

The possibility of using improvised means when assembling the crusher;

The use of sheet stainless material for the assembly of the unit reliably protects against the formation of rust during operation, and also prevents the formation of foreign odors in the juice.

The equipment has no significant drawbacks, except for the inability to use units with a destemmer to obtain pulp from nutmeg varieties.

How to make a crusher with your own hands

It is quite possible to assemble a very technologically advanced, but overnight simple crusher for grapes on your own. The cost of its manufacture is minimal, and in terms of efficiency it is not inferior to factory products designed for processing small volumes of raw materials.

Installation steps

1. Knock down the frame from the boards. It is preferable to use oak blanks. This element in form represents two long boards connected to each other by two short transverse elements. The parameters are determined depending on the dimensions of the rolls and the hopper, which are subsequently installed on the frame.

2. Prepare windrows. They can be taken from an old washing machine (an element for wringing clothes) or made independently from wood, giving relief to the surface. A pipe will work too. To make a relief on the surface, you need to draw several lines diagonally or along the end sides of the roll. According to the basting, holes or notches are made every 5 mm with a depth of 5 mm and a diameter of 10 mm.

After the grapes are harvested, many gardeners, especially those who cultivate technical varieties, start making homemade wine. At the first stage, of course, you will need to grind the berries, crushing them to a pulp state.

If earlier it was customary to grind berries directly with your hands or feet, then at present this not very hygienic method has been replaced by modern aggregates - crushers. They made it possible to automate labor and save time and effort in the manufacture of a large amount of an alcoholic beverage loved by many.

Purpose and principle of operation of the crusher

Almost all crushers for crushing berries have a very simple, but at the same time effective design. The units consist of a receiving hopper for loading, a pair of parallel crushing rollers and a pulp collection tank.

The volume of grapes required for processing is loaded into a special receiving container. Then, mechanically or by means of electricity, crushing rollers are brought into operation, which crush the grapes and transport them to the pulp collector.

The main features of such a unit are the presence of a gap between the teeth of the crushing rolls, as well as their rotation in different directions. The gap allows you to leave the grape seeds intact, which is very important for obtaining high-quality wine. Damaged bones give the finished drink excessive bitterness, which is due to too much tannins in them.

Types of crushers

Today it is possible to purchase wooden, plastic or stainless steel grape crushers. The main condition for a quality unit is the manufacture of parts involved in the process of grinding berries from materials that are not subject to oxidation.

The simplest option is a wood chipper. A more convenient and modern option is a manual or electric crusher equipped with a comb separator. Stainless steel crushers are characterized by high quality, which are very easy to clean and wash.

Crushers with and without destemmer

Grape combs are able to give the wine astringency and richness characteristic of high-quality drinks. However, their excess very often causes a bitter or unpleasant taste of the drink, and also negatively affects its color and transparency. And if in the manufacture of red wines it is allowed not to remove the grape ridges, then for white wines such a procedure is mandatory.

Crushers-stemmers used for grape processing are represented by two main types.

Roller destemmers

Such a unit best meets the requirements of the technology for the preparation of raw materials for wines and allows you to get high-quality must. In our country, the production of such crushers has been established. The principle of operation is based on the work of the rolls and the destemmer. A pair or more horizontal rolls are cylindrical and rotate in opposite directions. The size of the gap between the rolls is regulated by a special device. Rolls have a corrugated, smooth or bladed surface and can be four-, six- and eight-bladed. Profile rolls are predominantly used.

Impact-centrifugal crushers-destemmers

Centrifugal crushers, or CDG, can be either vertical or horizontal. The process of crushing grapes occurs as a result of the blows of the rotor, rotating at a speed of up to 500 rpm. The use of this variant of destemming crushers is characterized by the most complete wort yield with an increased amount of coloring and phenolic substances. As a rule, CDG is used in the manufacture of wine from red grapes.

Mechanical and electric crusher

The principle of operation of a standard electric crusher has minor differences from the operation of a mechanical apparatus. A special feature is the presence of a special comb separator, which is a horizontal cylinder with a shaft and helical blades. Such elements allow you to qualitatively and quickly separate the grapes from the ridges. As a result of the translational movement of the helical blades, the ridges are pushed outward. Only juice and pure grapes enter the crushing tank.

Benefits of using crushers

The grape crusher is a useful and practical unit for those involved in winemaking. The use of such a device in the manufacture of wine has a number of advantages:

• reduction in several times the technological loss of pulp;
• lack of saturation of the pulp with components undesirable for the final product;
• saving time and effort;
• obtaining higher quality pulp;
• the design of the unit is simple, reliable and very durable;
• manual, or mechanical, crusher can be used in the absence of electricity;
• high-quality stainless steel crusher is reliably protected from corrosion and does not impart extraneous odors to grape juice.

It should be remembered that crushers equipped with destemmers are not used when processing Muscat grapes.

Making a crusher with your own hands

A simple, but rather technologically advanced grape crusher is quite easy to make with your own hands. With small volumes of making homemade wine, it makes no sense to purchase a factory design, which, by the way, is quite expensive. The independent production of such a unit will take a little time, and in terms of efficiency it will almost not be inferior to the devices sold in stores.

Crusher manufacturing instructions:

1. Manufacture of the body from any material, the most preferred option is high-quality oak boards.
2. Making a drum, or beater shaft, from a pipe and equipping it with stainless steel blades 1.5 mm thick
3. Production of bearings in the form of plastic bushings with longitudinal slots, which will allow you to change the size of the gap between the drum and deck.
4. Installation of the drum using a metal rod with a diameter of 1.4 cm on bearings in the form of plastic bushings for sliding.
5. Installation under the beater shaft of a concave, or deck, the dimensions of which depend on the size of the berries. The most commonly used grid on the deck with a cell of 7.5 x 14 mm for small berries and 12.5 x 25 mm for large grapes.
6. Installation of the handle, with the help of which the beater shaft on bearings will be driven.

The manufactured manual crusher is installed on a container for collecting pulp. Almost any container can be used as a mezgopriemnik, but preference should be given to barrels or tanks made of food-grade plastic or stainless steel.

Do-it-yourself grape crusher (video)

Both a purchased and self-made unit for grinding grapes will become an indispensable tool for winemakers. It not only speeds up and facilitates the process of preparing the pulp, but also contributes to obtaining a more transparent, tasty and aromatic homemade wine.

Almost every household plot has a vine. And homemade wine is the pride of the owners. The taste characteristics of the prepared drink depend on the quality of the pulp. Manually preparing such a mass is a long and laborious process. To simplify it, a grape crusher was invented. What types are there and how to do it yourself - let's take a closer look.

What it is?

The crusher for grapes does not have a complex design and includes the following parts:

• Receiving bunker. The berry is loaded into it.
• Two parallel rollers with gears attached to them. This device produces the process of pressing grapes. In the case of a press and a centrifugal model, there are differences, which we will consider below.
• Container for collecting pulp.

The simplicity of the mechanism allows you to make it yourself from improvised materials.

Why a grape crusher?

The use of manual, foot labor is not hygienic, and it is a long process.

If you use a blender, food processor, then the wine filtration process will not be at a high level. That is, the final product will be with an unpleasant sediment that will spoil the taste of the drink. A grape crusher will allow you to filter the wine more finely. This means that the finished drink will have a beautiful color, taste and have a transparent consistency.

Kinds

The grape crusher has several classifications:

• Purchased design or homemade. The second option allows you to significantly save money by completing the unit from improvised means.
• According to the material of manufacture, there are wooden, plastic, stainless steel, combined (combine several types of materials).
• According to the principle of operation: mechanisms with rollers, centrifugal, with a destemming system.
• Mechanical and electrically driven.
• With and without comb separator.

As you can see, the models can be very different. It all depends on the availability of improvised means and the type of vine.

What is a comb?

If we consider a bunch of grapes, then it consists of the following components:

• Cluster leg. With its help, the brush is attached to the vine.
• Knot on the stem of a bunch. In its place there is a branch to separate tendrils with berries at the ends.
• The branching point of the first ridges to which the berries are attached.
• Blades.
• The top of the bunch.

This is a labor intensive process. To avoid it, a destemmer is built into the crushers. He just sorts the berries and this rubbish. A large number of ridges in the pulp will give the wine a rich herbal taste. And this is critical, especially for white wines. Consider several options for how to make a do-it-yourself grape crusher.

Mechanical roller devices

To begin with, a bunker is being run. It has the shape of a truncated pyramid. The material for its manufacture can be wood (preferably oak), plastic, stainless steel. The height of the sides can be from 100 to 500 mm. The parameter of the truncated cone must be equal to the length of the rollers.

Next, a wooden frame is made from timber. Suitable for a section of 50 x 50 mm. The frame length is 700 mm, but the width should be equal to the length of the rollers. The best option is 200 mm. The surface of the rollers must be corrugated. The distance between them is set to 2-3 mm. It is desirable to make an adjustable gap, since the berries can be of different sizes. The roller system is mounted in the middle of the frame on rods. From the outside, a gear system is installed, which will ensure the movement of the rollers in opposite directions.

The frame is mounted on a container for collecting pulp, and a hopper is attached to it for receiving grapes. The distance between the rollers and the hopper is no more than 10 mm. A handle is attached to one of the rods of the rollers. The simplest do-it-yourself grape crusher is made.

electrical device

On the basis of the previous home-made product, you can create electrical equipment, which will speed up the process of processing grapes at times. This will require an engine. You can take from an old washing machine or any other.

Transmission belt, shaft. Instead of manual control, an electric one with a belt drive is mounted.

Press

Such a manual crusher of grapes is characterized by simplicity and low cost. The device will require a stainless container with a tap, oak planks, a stainless strip (perforated can be used), a car jack, a welded frame. To begin with, an inner container is assembled from oak planks. Holes are drilled at the ends of the bars at the top and bottom, a fishing line is threaded and the frame of the future internal container is obtained. Its height must match the height of the stainless steel tank. Further, with the help of a strip, the resulting structure is fastened. A gap of 2-3 mm should be left between the bars. The next step is made for the press. It is also made from wooden bars.

Its diameter should be slightly smaller than the diameter of the inner wooden container. A metal container is fixed on the frame, the inner wooden part is installed in it, grapes are poured, support is placed under the press. As a force, you can use a screw system, or the second option is more affordable and is available to every car owner. The jack is installed on a wooden cover so that in the future the upper part of the frame becomes the second point of support. It is also necessary to prepare several bars and planks. When working with a jack, they may be needed. The faucet opens and the juice is squeezed out. Do not forget to substitute a container for juice under the stream.

centrifugal device

To do this, you need two stainless steel containers. The outer part is integral with a crane. Internal - perforated. A crushing shaft with blades in the form of blades is mounted in it. When moving with the help of centrifugal force, the berries are crushed against the wall. The resulting pulp enters the lower open part or through the perforation.

Crusher for grapes with destemmer

The above options are suitable for berries that have been previously de-stemmed. To speed up the process of processing grapes, a destemming system is mounted separately or in an existing crusher. For roller mechanisms, you can make an upper or lower version of the destemmer. To do this, you need a mesh with a cell of 10-12 mm made of stainless steel. Another shaft with blades in the form of blades arranged in a spiral on the shaft.

The work process is simple. Berries at the moment of forcing through the mesh are separated from the ridges and fall on the roller system for further pressure. And the combs with the help of a screw shaft from the grid go to the waste through additionally provided holes. For centrifugal devices, the same system is provided in the lower part of the tanks (grid and screw shaft with blades). The destemming system will help speed up the process of processing a bunch of grapes at times. We considered several options for how to make a do-it-yourself grape crusher. Below we consider the pros and cons of such mechanisms.

Advantages and disadvantages

Homemade grape crushers have several advantages:

• Speed. This is especially true for electrical devices with destemmers.
• Quality. The pulp obtained in this way has the best characteristics. In the future, straining is facilitated.
• Hygiene. Unlike crushers, hand and foot methods of processing grapes are not very clean.
• Compactness. Such devices do not take up much space.
• Ease of maintenance. The components are easy to disassemble and wash.
• Price. In the household of a zealous man, there will always be components for such units, and, accordingly, the cost of such devices is minimal. And at the same time, unnecessary, old things gain a second life.

As you can see, grape crushers have a large list of advantages.

And if you remember that the Russian people have always been easy on invention and ingenuity, then turning an old washing machine into a device for extracting grape juice will not be difficult even for a novice engineer. And if this equipment is made with adjustable mechanisms, then it will be possible to obtain not only grape juice, but also apple, pear and others. Such opportunities will increase the range and quantity of homemade products.
