DEVICE FOR MICROWAVE PROCESSING OF DIELECTRIC MATERIALS Russian patent published in 1999 - IPC

FIELD: microwave processing equipment. SUBSTANCE: device has microwave oscillator, chamber, in which load unit, unload unit, fan and ballast absorber are located, waveguide, which output is connected to chamber and input is connected to output of microwave oscillator. Goal of invention is achieved by introduced emitters, additional microwave oscillators, ballast absorbers and waveguides, which outputs are connected to chamber and inputs are connected to outputs of additional microwave oscillators, which are located in plane which is perpendicular to longitudinal axis of chamber in symmetry about this axis in order to provide uniform heating of processed materials on all sides. Ballast absorbers are located on inner surface of chamber walls in opposite to output horns of emitters. In addition size of funnels of horns is reverse proportional to size of chamber walls which are located in opposite to them. Wide walls of opposite side waveguides are perpendicular to one another in points of their connection to corresponding emitters. Output horns of emitters are covered with suppressing insertions which are transparent to radio waves. In addition device has conveyor belt, which is located along its longitudinal axis. EFFECT: uniform heating of processed materials on all sides, exclusion of local overheating. 5 cl, 3 dwg
