PROCEDURE FOR GRAIN PROCESSING IN DIRECTED AIR FLOW AND FACILITY FOR IMPLEMENTATION OF THIS PROCEDURE Russian patent published in 2010 - IPC B02B1/08 F26B5/00 

FIELD: agriculture.

SUBSTANCE: invention refers to food and agricultural branches of industry and can be implemented at processing of grain crops at preparing them to long-term storage. The essence of the procedure for grain processing in directed air flow consists in running grain through a system of stationary waves formed by means of interaction of directed in a processing vertical cylinder-conic chamber air flow whirled relative to central axis with air flow and air transported grain flow coming towards each other in this chamber. The facility for grain processing in directed air flow consists of an air duct and the vertical chamber. The vertical chamber is cylinder-conic and from above is connected with an air-transporting branch for grain loading, while beneath it is equipped with a channel for processed grain unloading and for inflow of opposite counteracting air flow. At least two air inlets are made on the vertical cylinder-conic chamber; the inlets are tangentially arranged to direct whirled air flow relative to central axis of the vertical cylinder-conic chamber. The facility is equipped with an air drive coupled with the cylinder-conic chamber by means of connecting air channels and furnished with a dust bag with and unloading hatch from beneath.

EFFECT: facilitates considerable decreased power expenditures for grain processing, also maintaining high quality of grain and eliminating successive heat treatment of grain.
