Description

The invention relates to grain processing technology and can be used to separate mineral surface contaminants and shells of grain.

A device for processing grain is known, comprising a drive, receiving and exhaust nozzles located in a housing, a rigidly fixed upper horizontal disk with a receiving hole in the center and a lower horizontal disk fixed coaxially on a vertical shaft with the possibility of simultaneous circular translational motion and rotational movement around its axis, a mechanism for regulating the gap between the disks (RF patent No. 2060823 B02B 3/02).

The disadvantage of this device is the inability to control the degree of peeling directly during operation.

Closest to the proposed is a peeling machine, consisting of a housing, a rotor with blades located therein, loading devices, devices for restricting the movement of grain in the housing, including at least two reflectors, the reflectors being movable to ensure uniform reduction of the outlet section of the housing, as well as the complete opening of the latter, while the casing is multifaceted (RF patent No. 2060825 B02B 3/08).

The disadvantage of this machine is the design complexity.

The technical task of the invention is the creation of a machine for peeling grain, in which two zones of grain processing are used to ensure the improvement of the quality of peeling products.

The technical result is achieved by the fact that in the proposed machine for peeling grain containing a rotor with blades located in it, loading and unloading nozzles installed in the deck body, a rotor drive and rotor disks with a variator, in order to improve the quality of grain peeling by reducing the amount of crushed core , it is equipped with disks of various materials - one abrasive, the other made of rubber, and the edges of the inner surfaces of the disks have slices at an angle of 15-20 °, while the disks rotate in opposite directions, and deck is lined with elastic material.

Improving the quality of peeling products is achieved as a result of peeling uniformity due to the creation of two zones of grain processing, as well as the operational regulation of the degree of peeling and the formation of a uniformly distributed grain flow at the outlet of the housing, which allows to increase the efficiency of separation of peeling products. Only the combination of essential features available in the proposed machine allows us to achieve this goal due to the fact that at the grain inlet there are movable disks with opposite rotation and sections, and at the exit there is a blade rotor with a deck lined with elastic material to ensure uniform soft peeling grain.

Figure 1 schematically shows a machine for peeling grain; figure 2 is a view aa (paddle rotor) of figure 1.

The machine for peeling grain contains a housing 1, a rotor with blades 2 located in it, a loading 3 and an unloading 4 nozzles installed in the housing 1 deck 5, lined with elastic material, a rotor drive 6 of the rotor 2 and disks 7 with a variator 8, in order to improve quality peeling of grain by reducing the amount of crushed core, it is equipped with disks 7 of various materials - one abrasive, the other made of rubber, and the edges of the inner surfaces of the disks are cut at an angle of 15-20 °, while the disks 7 rotate in opposite directions.

Machine for peeling grain works as follows. The drive 6 drives the rotor 5 and the variator 8, which rotates the disks 7 in opposite directions. When filling the grain through the loading nozzle 3, it enters the inner sections of the discs 7, which contribute to a uniform distribution of grain on the inner surface of the disc 7. The grain is peeled and evenly sprinkled on the cone of the rotor rotor 2. Due to centrifugal forces, the grain is discarded by the rotor blades 2 on deck 5 and flakes additionally. Exfoliated grain and waste are removed from the machine through the discharge pipe 4.

Thus, the working part of the disks installed at the inlet processes the grain surface with minimal pressure, then it is discarded by the rotor blades on the elastic lining of the deck at the outlet, which creates an increase in the working surface due to the creation of two grain processing zones and provides an improvement in the quality of peeling products.
