APPARATUS FOR PRESOWING MICROWAVE TREATMENT OF SEEDS Russian patent published in 1997 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has base carrying loading and receiving hoppers, microwave source and belt conveyor. Microwave source has N antennas positioned along conveyor belt and connected to respective microwave generators. Conveyor has N pairs of rollers with roller axes being in parallel one with another. Axes of antennas are also in parallel one with another. Conveyor belt embraces each pair of rollers so as to define S-shaped curve. Each pair of rollers is offset relative to axis of respective antenna in the direction opposed to that of conveyor belt by value equal to 0.8+1.2 ( + h), where Di is diameter of roller of i-th pair of rollers, proximate to axis of i-th antenna; h is thickness of belt. EFFECT: increased efficiency, simplified construction and improved quality of treated seeds. 2 cl, 1 dwg
