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.

The purpose of the invention is the intensification of the process of juice separation and increase the reliability of the device.

The drawing schematically shows the proposed device.

The device consists of a housing with a loading hopper 1 and perforated hatches 2, two perforated hollow cheeks 3, upper axles 4 and lower axles 5. which are installed in the guides b of the housing and are interconnected by power elements of the drive 7. In the lower part of the housing 1 are installed conveyor screws 8 and juice collector 9. In the upper part of the housing 1 there is a uniform assembly

the distribution of the layer of raw materials 10 (hydraulic or mechanical). The guides 6 of the housing 1 are equipped with limit stops 1.1. .

A device for extracting juice from fruit-bearing raw materials works as follows.

The raw material is fed into the hopper 1, from where it enters between the walls of the housing 2 and the perforated cheeks 3, divided into three streams. In case of loading raw from. vehicles include a drive unit forced distribution of raw materials 10, achieving uniform distribution of raw materials over the entire surface of the housing. By turning on the drive, the power elements 7 are driven, which are driven through the upper axles 4 and lower axes 5

stupid movement along a given trajectory hollow cheeks 3.

The cycle of compression and pressing of the raw material between the cheeks 3 and the perforated walls 2 begins. Under the action of pressure, the juice passes through the perforations of the walls of the body and cheeks and is collected in a wort collector 9, from where it is diverted for further processing. The lower axes 5 are hollow and do not impede the drainage of juice from them into the muster through specially provided trays with drains.

Upon reaching the extreme position by the cheeks 3, the drive is turned on in the opposite direction and the power elements 7 tighten the cheeks together, the product is already pressed between them. At this time, the pressed mass jams between the cheeks and the walls of the body. Under the action of its own weight, the mass enters the conveyor screws 8 and part of the feed is removed from the device.

Press cycles are repeated many times until the raw materials are completely removed from the device. The passage between the elements of the device (walls 2. and cheeks 3), the raw material is pressed under conditions of reducing the cross section due to the design of the chambers in the form of wedge cavities.

To provide the necessary differential pressures in the upper and lower zones of the device (between the cheeks 3 and between them and the walls 2), by changing the degree of their deformation, adjustable limit stops 11 in the grooves of the device are provided. They control the stroke of the cheeks 3 and thus the degree of deformation of the layer

squeezing (layer thickness), obtaining the necessary pressure in it.

The implementation of the drainage surfaces wavy in the longitudinal direction prevents the departure of raw materials from the pressing zones during the process,

Claims (2)

1. A device for extracting juice from fruit-friendly raw materials, comprising a housing with a loading hopper and perforated walls, a pair of hollow perforated pressing cheeks installed therein, transporting screws, a wort collector and a drive located underneath them, and the surfaces of the walls and hollow perforated pressing cheeks are made profiled. It is important that, in order to intensify the process of juice separation and increase the reliability of operation, it is equipped with a unit for even distribution of raw materials installed in the upper part of the housing, hollow perforated pressing cheeks are interconnected and drive their reciprocating movement by means of power elements, and their upper and lower ends are installed in the guides, while the surface profile is perforated the walls and hollow perforated lounging cheeks have a wavy shape in the longitudinal direction. 2. The device according to claim 1, with the exception that it is equipped with stops-regulators of the course of the hollow cheeks, the protrusions of the corrugated surface of the hollow cheeks, are opposite the hollows of the corrugated the surface of the walls of the housing.
