FLUIDIZED BED GRAIN DRYING APPARATUS Russian patent published in 2001 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has drying chamber connected with feeding hopper, intermediate hopper, discharge hopper, gas supplying (delivery) box, gas discharging (suction) box, first gas distributing grid for gas supplying box, second gas distributing grid for gas discharging box, and conveyor with scrapers. Gas distributing grids also serve as tables for conveying grain by scrapers in drying chamber and in gas discharging box. Scrapers arranged in the vicinity of drying chamber outlet end and gas discharging box are enclosed in tunnels and adapted to form closures of conveyed grain. Apparatus allows power consumption for drying process in fluidized bed to be reduced due to recovery of part of heat energy by reclaiming air heat produced in the process of grain cooling. Apparatus is used for drying seed and food grain. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 2 cl, 2 dwg
