UHF-STAND FOR LOOSENESS AND GRANULAR MATERIALS HEAT TREATMENT Russian patent published in 1994 - IPC

FIELD: corn and cereals treatment technology, radio and mechanical engineering. SUBSTANCE: UHF-stand has two or three vertical heating chambers which are connected by intermediate, input and output bunkers. Bunkers are blowing through by air jets heated by several UHF generators mounted at two reciprocally perpendicular walls of heating chambers. With respect to desirable treatment efficiency or time duration of heating some stands can be combined in parallel operating assembly with common feeding hopper using. It will be possible too stands consequent assembling for double-heat treatment the same product by pneumatic product guide using. Stand has rotary valve for granular product distribution and air jets dispersers in every bunker. EFFECT: higher efficiency of heating operation and wider range of operational possibilities. 7 cl, 8 dwg
