UNIVERSAL MICROWAVE DRIER Russian patent published in 1998 - IPC

FIELD: agriculture, wood processing equipment, furniture manufacturing. SUBSTANCE: device is designed in two modifications: chamber and pipeline types. Chamber drier has emission system which has resonant antennas, which are designed as slotted-guide emitters which are connected to serial circuit of slotted-guide branches. Pipeline drier non-resonant slotted-guide antennas which are short-circuited at end. They are located in perpendicular to flight conveyor. Position of slots, their length and distance between them provide control over emission field with several peaks in vertical plane along flow of dried material. Said peaks are grouped along direction which is defined by Brewster angle. In addition both modifications of drier have moisture removal system, which has electric radiators and exhaust fans, system for testing and regulation of matching microwave power source and feedback circuit. EFFECT: increased functional capabilities. 8 cl, 7 dwg
