FIELD: agriculture. SUBSTANCE: this method prescribes vacuum air suction of grain from ground surface, conveying sucked-in grain under excess air pressure built up by fan, directing suck-in air flow as regularly ascending current and force flow as descending current directed at acute angle relative to horizontal plane and towards suck-in air flow, directing suck-in and force air flows as concentric and adjacent circular currents revolving in same direction, and streaming force flow in the form of jets directed at same acute angle relative to radius. EFFECT: more sophisticated technique. 1 dwg
