SU435269A1 - PRESS OF CONTINUOUS ACTION FOR THE EXTRACTION OF JUICE FROM FRUIT AND BERRY RAW MATERIALS - Google Patents

Description

one

The invention relates to the winemaking and canning industry, namely to continuous presses for extracting juice from a fruit-bearing raw material.

A continuous press is known for extracting juice from a fruit-bearing raw material, for example, from a unit containing a receiving hopper, a perforated cylinder, an auger located in it, a feeding-pressing device adjacent to a perforated cylinder and consisting of a half-cylinder, a rotating drum located in it, and arcuate cheeks.

The proposed press increases the yield of the wort, prevents the extrusion of the pulp through the perforation of the cylinder and improves the quality of the juice. This is achieved by the fact that the arcuate cheek is pivotally mounted, installed so that there is a wedge space between it and the drum and communicates with the hydraulic system, telling the cheek a reciprocating movement. At the same time, the cheek surface, located at a distance from the hinge, in the low pressure zone, is made perforated and provided with a juice box, and at the top of the wedge space there is a spring-loaded cleaning strap, which creates a directional flow of the pressed mass towards the screw rotation.

The spring loaded cleaning strip is located tangentially to the screw.

The surface of the drum is made in the form of a regular polyhedron formed

arcuate surfaces.

FIG. 1 shows the proposed press, a longitudinal section; in fig. 2 is a section along A-A in FIG. one.

A continuous press for extracting juice from a fruit-bearing raw material (block) contains a receiving hopper 1, a perforated cylinder 2, a screw 3 in it, a feeding-pressing device adjacent to a perforated cylinder.

2 and consisting of a semi-cylinder 4, a rotating drum 5 and an arched cheek 6 located therein.

The arcuate cheek 6 is reinforced with the help of a movable hinge 7, installed with the formation of a wedge space 8 between it and the drum 5 and communicated with the hydraulic system (with the hydraulic cylinder 9), telling the cheek 6 a reciprocating movement. The surface of the cheek 6, located in

away from the hinge 7, in the low pressure zone, is perforated, and at the top of the wedge space 8 there is a spring-loaded strap 10, which serves to create a directional flow of the pressed

mass towards the rotation of the screw 3.

The spring-loaded cleaning strip 10 is tangentially located to shchyuyku 3.

The surface of the drum 5 is made in the form of a regular polyhedron formed by arcuate surfaces. The screw 3 has a tubular perforated shaft 11.

The collection 12 serves to collect the wort, in addition, at the top of the cheek 6 there is a juice collection container 13 with a nozzle 14.

In cylinder 2 there is a baffle 15.

The press works as follows.

The raw material to be pressed is fed to the receiving hopper 1, from where it is captured by the drum 5 and fed into the wedge space 8, where it is compressed and the juice is transferred to the juice collection container 13.

Under the action of the hydraulic cylinder 9, the cheek 6 moves, increasing and decreasing alternately the wedge space 8, which makes the wort easier to separate and reduces the reduced coefficient of friction of the raw material against the cheek 6. This facilitates the movement of the raw material to high pressure zones. The absence of perforation in the lower part of the cheek 6 eliminates the pushing of the raw material through the holes and its penetration into the wort.

The pulp, partly wrung out, having increased mechanical characteristics, carried away by the friction forces on the surface of the drum 5, is pushed into the channel of the screw 3 moving towards it, in which there is pressure that promotes the further selection of the wort. Plank 10, the end of which slides along the surface of the drum 5 under the action of the spring, cleans it and guides the pulp into the screw channel of the screw 3. The pulp is caught by the auger blades, the particles of the compressible mass are moved and the direction of the pressing forces is changed. This restores the drainage channels in the pulp and contributes to the removal of the wort both into the cavity of the shaft of the screw 3 through the perforated surface and through the surface of the perforated cylinder 2. The wort enters the

collections 12, and a part of it, having separated out in the end part of the press, goes through the cone 16 nozzle. , as well as the selection of wort.
