The perforations are communicated by channels with a distribution chamber. Distribution chamber communicated with a source of compressed air. The contact zone of the channels with the distribution chamber is located behind the line of interaction of adjacent rolls and is 90-120 ° C. in the course of rotation of the latter. 5 il.

Description

The invention relates to food industry equipment and can be used in the production of pectin from cotton casement flaps.

A device is known comprising drive rolls whose working surface is made with transverse cutting reefs and perforations communicated by channels with a distribution chamber.

The disadvantages of the known device are poor-quality processing of raw materials and sticking of the latter on the surface of the rolls.

The aim of the invention is to improve the cleaning of the rolls and the processing of raw materials.

The goal is achieved by the fact that in a device for processing plant raw materials containing loading and unloading trays, driven rolls whose working surface is made with transverse cutting reefs and perforations communicated by channels with a distribution chamber, perforations are made in reef declines, the distribution chamber communicates with the source compressed air, and a zone of contacting the channels with a distribution chamber, perforations are made in reef declines, a distribution chamber communicates with a source of compressed air, and contacting it with channels distribution chamber located behind the line of adjacent rollers and reaction is 90-120 ° during the rotation of the latter

Each of the swaths is hollow and its internal cavity is divided by hermetic partitions 7, forming cells 8.

In recessions dips 9, annular grooves 10 are machined and perforations 11 are made, the latter in adjacent grooves arranged in a staggered order with a shift of half a step,

A distribution chamber 12 is movably attached to the end of the roll, the slot 13 of which is 90-120 ° and communicates with the compressed air pipeline 14. The first (lower) roll is driven by the drive 6, and from the latter, the rotational motion is transmitted to the second (intermediate) and third (upper) rolls, and to create friction, the angular velocities of the rolls during the transmission of the rotational motion are reduced (ol (OQ.

 adz).

The degree of processing (deformation) of plant raw materials is governed by the size of the gap between the rollers, therefore, the axle box 15 of the intermediate roll is fixed in the frame 1 movably and connected to the mechanism 3 for adjusting the roll gap, and the axle boxes of the first and third rolls are fixed in the frame

The device works as follows.

Plant material, mainly the pre-swollen flap of the cotton box, is fed in bulk through the loading chute 4 to the upper and intermediate rolls 2. Due to the rotation of the rolls, the raw material is pulled into the space between the rolls and deformed between the reefs 9. The size of the gap between the reefs of the adjacent rolls is set and adjusted by mechanism 3 The bulk of the material, having passed the kinestatic treatment zone, is fed to the lower roll. A part of the material is removed onto the surface of the rolls after the contact line of the adjacent

rolls due to air jets flowing through the perforations 11. During the rotation of the rolls, each cell 8 is connected in series with the slot 13 of the distribution chamber 12. The chambers of all the rolls are connected to the compressed air pipeline 14. Thus, the raw material is processed through the lower pair of rolls and removed through the discharge chute 5

The contact area of the cells with the distribution chamber is an angle of 90-120 ° and is located behind the line of interaction of adjacent rolls in the course of rotation of the latter. The angle of scattering slot

13, equal to 90-120 °, and their location was chosen from the design considerations of the roller machine, taking into account the placement of the rolls, their diameter and ease of maintenance and repair

of works

The cotton case with a deformed structure, thus treated, is better hydrolyzed and extracted and the yield of extractive substances is increased, and blowing out the perforations with air flow ensures the cleaning of the roll surfaces of adhered material.
