The invention relates to the food industry, namely canned food.,. its wine and winemaking industry, in particular, to devices for extracting juice from the fruit-bearing raw material.

The aim of the invention is to increase the juice yield.

The drawing shows a device for extracting juice from a fruit-bearing raw material.

The device molestes the body with the loading hopper 1 and the perforated walls of 20 In the case with the formation of the pressing chamber 3 vertically there is a hollow a perforated plate 4 fixed on the horizontal axis 5 with the possibility of swinging around it Axis 5 perforated plate 4, (fixed in the guides 6 and connected to the drive mechanism 7 for its reciprocating movement in a horizontal plane. In the upper 35 parts of the pressing chamber 3, stops 8 are mounted, guides with a perforated plate 4 and limit its movement.

A discharge mechanism in the form of a screw 9 mounted in a perforated half-cylinder 10 is installed in the lower part of the chamber of the press-0. For collecting juice, the device has a juice collector 11.45

The device works as follows.

Raw materials, such as grapes, feed into the hopper 1, from where it enters the pressing chamber 3 between the perforated walls 2 and the perforated plate 4. By activating the drive 7, the axis 5 moves in the guides 6 to the plate 4 and attaches a swinging movement (about axis 5 This is due to the different density of the raw materials in the upper and lower parts of the pressing chamber 3. It captures from the mass of raw material,.

c, a volume equal to the working volume of the pressing chamber 3. Under the action of uneven pressure, the raw material is pressed and simultaneously moves along the plane of pressing in the direction to the bunker, if the angle between wall 2 and plate 4 is open, or to the discharge screw 9, after the angle between wall 2 and plate 4 is closed. Due to the rubbing of the raw material against the walls and the slab, a difference arises in the speed of moving the layers and friction between them, which leads to the destruction of the raw material. The separated juice through the perforated walls 2, the perforated plate 4 and the semicylinder 10 is removed to the collection container 11.

After plate 4 of stop 8 reaches, further movement of axis 5 leads to alignment of plate 4. As a result, the entire lower part of plate 4 presses on the previously destroyed raw material, which is located in the lower part of the pressing chamber, allowing additional extraction of juice in a static pressing mode.

Upon further movement of the lower part of the plate 4, an open angle is formed between the plate 4 and the wall 2, which contributes to the movement of raw materials, additional destruction and the elimination of dead zones in the working volume of the pressing chamber. When the extreme position is reached by the lower part of the plate 4, the drive mechanism 7 is turned on in the opposite direction. The perforated plate 4 moves in the opposite direction and interacts with the raw material in the pressing chamber 3 between the other perforated wall 2 and the plate 4, and with the stops 8, while performing the described movements and ensuring efficient extraction of the juice from the raw material. The pressed mass of raw material from the upper zone of the pressing chamber, as well as new

portions of the raw material from the bunker fall into the gap formed between the plate 4 and the wall 2. When the perforated plate 4 reaches the extreme field, the cycle is repeated. The pressed mass of raw material by the discharge screw is periodically or continuously removed from the working zone of the pressing chamber.
