Abstract

Usage: extract juice from fruit-bearing raw materials under conditions of intensification of the process of juice separation. SUMMARY OF THE INVENTION: the device comprises a housing with a receiving hopper and a juice collector, a perforated chamber mounted in the housing, within which transporting screws are placed and a perforated cheek is hollow, swingable between them, the axis of swing of the cheek is located below the axes of the transporting screws. In the middle part of the hollow perforated cheek, channels are made connecting the pressing zones located on both sides of the cheek. 1 ill.

Description

The invention relates to the wine and canning industries of the food industry and is intended to extract juices from fruit-bearing raw materials, in particular from grapes.

A press is known for extracting must from whole bunches of grapes, which contains a case with a hopper and perforated walls, inside of which a perforated cheek is hollow in the middle, fixed to the horizontal axis with the possibility of oscillating movement from the drive mechanism, and a pulp unloading device located in the lower part (1 )

The disadvantage of this press is the low intensity of the process. The product in the pressing zone formed between the walls and the cheek, due to the ineffective organization of its movement, is not sufficiently subjected to destruction and loosening, which reduces the efficiency of the juice separation process.

These disadvantages are partially eliminated in a device comprising a housing with a receiving hopper and perforated walls, a hollow perforated cheek mounted between the walls and mounted on the shaft with the possibility of swinging under the action of the drive mechanism and the unloading device. To intensify the process of juice separation, this device is equipped with special ledges-reflectors of raw materials (2).

A disadvantage of the known device is the insufficiently high intensification of the process of juice separation, especially from difficult to destroy raw materials, which is due to the fact that the incoming raw materials are also not completely destroyed and loosened in the pressing chambers, despite the decrease in the thickness of the pressed layer, a partial change in the direction of the pressing forces and a partial change trajectories of movement of the raw material (which envelops the indicated ledges-reflectors).

A device for extracting juice from vegetable raw materials is known, comprising a housing with a loading hopper and perforated walls, mounted inside the housing with the ability to swing around a horizontal axis located below the axes of the conveying screws, a perforated cheek, hollow perforated blades connected at the upper ends to the cheek by means of flexible elements conveying augers, juice collector and drive mechanism (3).

The disadvantage of this device is the low intensity of the process of extracting juice from raw materials. The raw material, moving downward, forms a decreasing continuous stream in the form of a gradually compacting mass due to the gradually increasing pressure from the side of the cheek, which prevents the intermediate loosening of the raw material and, consequently, the intensification of the wort separation process.

The aim of the present invention is to intensify the process of juice separation.

The goal is achieved in that in a device comprising a housing with a receiving hopper and a juice collector, a perforated chamber installed in the housing, inside which transporting screws are placed and a hollow perforated cheek is placed, swingable between them, the axis of swing of the cheek is located below the axes of the transporting screws, according to the invention, in the middle part of the hollow perforated cheek, channels are made connecting the pressing zones located on both sides of the cheek.

SUMMARY OF THE INVENTION that in the pressing chambers formed between the walls and the cheek, a regime of pressing and loosening of raw materials is created, which favors the intensive destruction of juice-containing cells and the removal of juice from the layers of destroyed raw materials through the perforated surfaces of the walls and

cheeks, due to exposure to raw materials by pressing, partial destruction and intensive drainage of juice in the area of action of continuous sections of the cheek and intense

destruction and loosening of the raw material during throttling of the raw material flow through the overflow longitudinal channels from one pressing chamber to another with a swinging motion of the cheek. Device

schematically depicted in FIG. 1.

A device for extracting juice from fruit-friendly raw materials comprises a housing 1 with a receiving hopper 2, in which perforated walls 3 and hollows are placed

a perforated cheek formed from solid sections 4 and 5 and longitudinal longitudinal channels 6 is mounted on the axis 7 with the possibility of swinging from the drive mechanisms 8 and forming a pressing chamber 9 on both sides of the cheek, as well as a juice collector 10 and unloading screws 11.

The device operates as follows.

Raw materials are fed into the receiving hopper 2,

filling the pressing chamber 9 formed between the cheek and the walls 3. By means of the drive elements 8 pivotally connected to the cheek, the latter is provided with a rocking motion. As the cheeks move to the wall 3 in the pressing chamber 9, pressing zones I and III and mixing and crushing zones of the raw material II are created. In the pre-pressing zone 1 by the action of solid elements

the cheek 4 there is a partial destruction of the raw material and intensive drainage of juice through the perforated surfaces of the walls 3 and sections of the cheek 4. At the initial moment, when the cheek 4 moves to the wall 3, the raw materials

partially moves up towards the receiving hopper 2. As the cross section to the hopper decreases, static conditions are created for pressing in this zone.

In zone 11, when the cheek moves, the partially destroyed and depleted raw material under pressure in the pressing chamber 9, formed between the cheek 4 and the wall 3, towards which the cheek moves, is pressed (throttled) through transfer longitudinal channels b into the pressing chamber 9 on the other side of the cheek , where at this time only the pressure of the column of raw materials acts on the raw materials. Indicated movement of raw materials in the horizontal direction

leads to its loosening and destruction both directly in the transfer channels 6 themselves and in the press chambers due to friction between the layers of raw materials moving with different speeds.

In zone III, under the action of continuous sections of the cheek 5, the loosened and destroyed raw material is finally pressed, after which the pressed raw material is removed by unloading screws 11

The juice separated in sections I and III of the pressing chamber 9 is removed through the juice collector 10 and sent for further processing

The raw materials, when moving from the hopper 2 to the unloading screws 11, are subjected to repeated cyclic effects in each of sections I, II, and III of the pressing chambers 9, which makes it possible to intensify the process of extracting high-quality juice from fruit-bearing raw materials at a self-regulating pressing pressure depending on the nature of the structural raw material
