The invention relates to the grain processing industry, as well as to devices for peeling, grinding and polishing grain.

The purpose of the invention is to increase the productivity and quality of the processed grain;

In the proposed device, which contains a housing, a loading device: a treatment, radially arranged cylindrical working chambers and a communication mechanism to working chambers of a planar motion, each working chamber consists of a series of telescopic sections, installed rotatably in opposite directions with respect to the vertical axis of the working chambers,: The drawing shows a device i for peeling, grinding and polishing the grain.

The device consists of a drive shaft 1 mounted in bearings 2 and 3 of housing 4, carrying two stationary gears 5 and 6. The third stationary gear wheel 7 rests on bearings 8 mounted on the drive shaft 1 and is kept from rotating by a cross 9, laid out in to the power supply nozzle -10 and connected to the housing 4. On the drive shaft I, the carrier I1 is rigidly fixed with 12 axes of working chambers on it, formed by feed 13, intermediate 14 and output 15 by sections formed in the form of vertical, telescopic ki disposed sections. All three sections are fixed in bearings 16, 17 and 18, installed in the housings of the supporting frames of 12 working chambers, and equipped with gear rims 19, 20 and 21, respectively. The gear rims 19 and 21 of the inlet 13 and the withdrawal of the shdh 15 sections engage with the fixed gears 7 and 5. To change the direction of rotation of the intermediate sections 1, the gear rims 20 are engaged with the fixed gear 6 through the intermediate gears 22, fixed -. Lenny in bearings 23 and 24 on the bearing frames of 12 working chambers. On these cases, the feed pipes 25 and races 2 are rigidly fixed, located in the annular collection 27, equipped with 28 k.tusktym patrol,

the water shaft 1 is connected to the shaft of the electric motor 29 by a gear 30,

The device works as follows.

The motor 29 through the transmission 30 drives the drive shaft 1, the carrier 11 and the supporting frames 12 of the working chambers, to which the supply 13 is fixed, the intermediate 14 and the output 15 of the section 15 are rotated. Gear rims 19 and 21, rolling on fixed gears 7 and 5, provide rotation of the inlet 13 and outgoing 15 sections around their own axis in the direction coinciding with the direction of rotation of the drive shaft 1, Intermediate gears 22, rolling in on the fixed gear wheel 6, receive a rotation around their axes and rotate the rims 20 with intermediate sections 14 in the direction opposite to the rotation of the drive shaft 1,

The receiving rotations from the supporting frames 12 of the working chambers of the feed pipe {tubes 25 are evenly distributed and the initial grain is transferred from the feeding nozzle 10 to the feed sections 13 of the working chamber.

The incoming grain flow during the planetary movement of the working chamber is subjected to centrifugal force during rotation around the drive shaft 1 and centrifugal force during rotation of the feed section 13 around its own axis. Such loading conditions ensure the creation in the working area of a sharply changing inertial field and a differentiated force effect on the elementary volumes of the processed grain.

Similar conditions are created in the intermediate 14 and outgoing 5 sections of the working chamber; however, changing the direction of rotation around the axes of these sections to the opposite ensures the creation of oppositely directed grain flows during the transition from the upper sections to the lower sections of the working chambers. The last circumstance, causing intense mixing and mutual interaction with respect to the moving elementary volumes of the grain mass, with varying load strength.
