DEVICE FOR SUPPLY OF GRAIN MIX INTO PNEUMATIC SEPARATING CHANNEL OF WINNOWER Russian patent published in 2010 - IPC B07B4/02 B02B1/02 

FIELD: technological processes.

SUBSTANCE: invention relates to the field of pneumatic separation for treatment of loose materials, mostly grain and grain materials from light admixtures and may be used in agriculture, flour-grinding, mixed fodder and other industries. Device comprises pneumatic separating channel with a transverse window for inlet of separated material and a valve. Valve is installed upstream window of pneumatic separating channel and is arranged as double-vane with the possibility of turn towards motion of grain flow.
