GRAIN MATERIAL SEPARATOR Russian patent published in 2006 - IPC B07B4/08 B07B13/00 

FIELD: agricultural engineering, in particular, equipment for separation of difficult-to-separate grain materials.

SUBSTANCE: grain material separator has separation chamber, horizontal air duct, charging hopper positioned above horizontal air duct in upper part of separation chamber, ascending flow air duct with air distributor, and separation product receivers. Separator is equipped with two air-permeable endless drive belts arranged in parallel with one another in upper and lower parts of separation chamber, and air intake mounted above lower branch of upper belt. Ascending flow air duct is mounted under upper branch of lower belt. Air distributor is equipped with grid having air flow draft increasing in direction away from charging hopper. Heavy fraction receiver adjoins charging hopper and light fraction receiver is mounted in opposite part of separation chamber.

EFFECT: increased efficiency in separating of various grain materials, including materials other than free-flowing materials.
