METHOD OF DRYING AND COOLING SEEDS AND GRAINS Russian patent published in 2003 - IPC

FIELD: methods of drying and cooling loose materials; farming; food- processing industry. SUBSTANCE: proposed method consists in drying materials in dense layer revolving around vertical axis at blowing the material with drying agent; upon reaching conditional moisture content by material, lower part of layer is unloaded and is cooled in dense layer by gas component; part of layer being unloaded is not subjected to final drying to conditional moisture content by 0.2 to 2% but is left at rest for at least one complete cycle of turn of layer, after which it is cooled by blowing with gas component for attaining conditional moisture content; material is unloaded both at continuous and periodic cyclic mode of rotation of layer; material which is not finally dried is unloaded on grate of aero-chute of cooling chamber at periodic unloading and cooled in fluidized bed of aero-chute. EFFECT: reduced power requirements. 4 cl, 3 dwg
