AERODYNAMIC DEVICE FOR DRYING AND CLEANING LOOSE MATERIALS Russian patent published in 1994 - IPC

FIELD: drying and cleaning loose materials. SUBSTANCE: aerodynamic device has housing with internal reflecting surface covered, for example, with foil and external black surface. Housing is provided with suction branch pipe with dust fan, discharge, recirculation and loading branch pipes, cyclone mounted on external surface of housing, heaters and vibratory body placed inside housing and fitted with inclined shelves arranged in zigzag and staggered order. Cyclone is connected with dust fan and recirculation branch pipe by means of air duct. Device is controlled from control panel. Loose material fed into housing moves in vibrating layer along vibrating shelves. Heaters and reflecting surface of housing heated by sun rays create radiant energy field responsible for drying moving material, which is blown through and cleaned by high speed air flow produced by fan. EFFECT: improved efficiency and high quality of material drying and cleaning. 2 cl, 1 dwg
