METHOD FOR DRYING RAW MATERIALS OF VEGETABLE AND ANIMAL NATURE Russian patent published in 2003 - IPC

FIELD: woodworking and food industries. SUBSTANCE: method designed for drying timber and products of vegetable and animal nature involves drying of timber, fish, meat, cherry, carrot, and the like by exposing them to electromagnetic field of extremely low or superlow frequency band, or to electromagnetic field amplitude-modulated by waves of extremely low or superlow frequency band, or to electric field frequency-modulated by waves of extremely low or superlow frequency band, or to electric field phase-modulated by waves of extremely low or superlow frequency band; carrier frequency for all kinds of modulated electromagnetic field may be from 30 to 10¹³ Hz and intensity of each of mentioned fields is 10-1400 A/m; exposure time is 10-900 minutes. Proposed method makes it possible to reduce power consumption by down to 10³ times compared with prior art. EFFECT: reducer power requirement. 15 ex
