GRAIN DRIER Russian patent published in 2004 - IPC

FIELD: agricultural engineering; drives. SUBSTANCE: proposed drier includes heat generator used to heat atmospheric air. Heated air is delivered through air duct, delivery channel and distributing chute into drying column into which seed material or grain is loaded by chain-bucket elevator. Hot air passing through grain extracts moisture and through outlet channel is subjected to settling in cyclone. Owing to provision and arrangement of shutters in delivery channel, distributing chute, outlet channel and chute collecting waste heat carrier, grain drier can be used for drying seed material and grain at different temperatures optimum for each grain culture. Original design of discharge mechanism provides quick and reliable unloading of required section of drying column. Making of drying plant in form of separate functional units provides possibility of equipping the plant with additional drying column. EFFECT: increased capacity of drier operating at harvesting. 8 cl, 8 dwg
