DEVICE FOR SEPARATION OF GRAIN AND OTHER BULK MATERIALS Russian patent published in 2014 - IPC B07B1/46 

FIELD: agriculture.

SUBSTANCE: invention relates to the equipment of agroindustrial complex, particularly grain processing enterprises, and can be used for clearing grains from fine impurities and for preliminary stratification of the grain mixture before feeding it to the aspiration channel when cleaning the grains from the light impurities. The separating device comprises a working surface with riffles in the form of plates mounted on it, bounded by the end and two side walls, the actuator for communicating the surface of rectilinear variations, and the feeder for supplying the initial grain mixture to the working surface. The working surface is made in the form of alternating parts of the surface with riffles, the height of which decreases in the direction of movement of the grain mixture, the smooth sieve surface or the sieve surface with riffles of constant height and the surface of the riffles, the height of which increases in the direction of movement of the grain mixture along the surface.

EFFECT: improving the efficiency of separation of different grain mixtures.
