For making various products wine industry uses each year, about 80% of the grapes are grown. He is one of the most valuable appearance of plant materials. Processing it is quite simple, and the resulting products are of high taste and nutritional qualities.

Technological stages of processing of grapes

After the crop is harvested, it is delivered to the winery for processing. This process consists of several stages:

  • Receiving, where the selection of the average sample from each batch of raw materials received;
  • Initial treatment, during which the grapes are subjected to cleaning;
  • Destemming, designed to separate the berries and ridges;
  • Fragmentation, providing processes through which the juice of the grape is released rapidly.

Features of the crushing of the grapes

This process happens in the crushing and pressing plants. Main kind of equipment that they used ‒ crusher for grapes intended for processing it into pulp and mash. Whatever the degree of crushing of the berries, it should minimize the violation of the integrity of the bones.

As the light of natural wine, champagne and cognac wine materials have a small extract, the crushing of berries for their production should be the lowest. Therefore, the crusher of the grapes in this case operate in easy mode.

As for full extractive wines, which include thick, quite heavy red wine, the berries are crushed for them more intensively.

Typically, the crushing process of the grapes combine with the separation of the ridges. This is because during the processing they can saturate the wort with substances that later will give the wine a rather unpleasant herbal flavor. An exception is the production of Kakhetian wines, when the ridges are not separated at all.

Modern businesses use crusher of grapes are of two types: centrifugal and roller. Their difference is in the intensity of crushing berries and various character effects on a bunch of grapes. Each of them has its special design and different operating characteristics. But both types have in common is that this is a crusher for grapes destemmer.

Centrifugal crusher

This type of crusher is characterized in that the crushing of the berries is due to the centrifugal force, which ensures the impact of clusters on the inner walls of the housing. The berries are quite hard mechanical stress and is largely saturated with oxygen. In the process unit crushes the berries, at the same time separating them from the crests.

press for grapes

This mechanical crusher for grapes consists of a housing equipped with a cover-drive, blade shaft, hopper and the tray, which is removed the ridges.

It Operates on the following principle:

  • Grapes entering the hopper is subjected to impacts of pests of the shaft;
  • Birds are separated from the ridges and come together with them on the surface of the cylinder is provided with a perforation;
  • Then, using the propeller blades, they wear out and fall through the holes in Mezhgosbank;
  • The ridges in this case are separated in a tray located at the top of the crusher, and get on the conveyor belt.

Roller crusher

This kind of crusher of grapes are used to separate the ridges from the grapes, followed by crushing of the berries. Design roll crusher consists of a more or less stable shaft, perforated cylinder and 4 rolls of food-grade rubber, which work in pairs.

The Principle of operation is as follows:

  • Grapes enters the unit, where the ridges under the blows of gross beat are separated from the berries and removed from the perforated cylinder;
  • After that the berries fall through the perforations on the rolls, by which the crushing.

The Unit has additional devices that regulate the distance between the rolls in the range of 3-8 mm. This gives you the ability to use the gentle crushing of the berries depending on their grades and physical performance.

The Pressing of the product

To be obtained in the process of crushing the pulp to allocate so-called the must (juice from grapes) use a special press. They are of two types-periodic and continuous action.

The Device of periodic action, in turn, are divided into basket, where the pulp is loaded into baskets, then pressed, and pneumatic. Such a press for grapes has a cylinder for loading the pulp and the pipe through which the injected air. When you extend the tube the pulp is subjected to pressing.

A continuous action press the pulp in the process of moving. They have a great performance with process automation. Such a press for grapes works by means of an auger, which moves and compresses the pulp.

Manual crusher for grapes

For those involved in the preparation of wine at homeconditions indispensable to be a hand crusher. It is a hopper with a stirrer, which pushes the berries between the rolls. By adjusting the distance between the last, it is possible to split different degrees, without damaging the seed.

With a capacity of up to 500 kg/HR can be processed in a sufficiently large volume of grapes to immediately proceed to the extraction of the pulp.
