PNEUMATIC SEPARATOR Russian patent published in 2010 - IPC B07B4/02 A01F12/44 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be implemented in agricultural engineering, and in flour-milling, granary and feed-mill industries for cleaning loose materials, mainly grain and grain materials from light-weight impurities with air flow. The pneumatic separator consists of pneumatically separating channel with a cross window for supply of separated material; in the channel a feeder in form of embossed roller with cells on external cylinder surface is mounted on a shaft. From the side opposite to the feeder there is made a chamber formed with a curvilinear upper wall corresponding to radius of turn of inclined surface hinged in a lower part. The upper wall is located at the level of the feeder.

EFFECT: upgraded quality of separation of grain material and reduced losses of full-value grain into wastes with light-weight impurities.
