APPARATUS FOR TREATMENT OF SEEDS WITH ELECTROMAGNETIC FIELD (VERSIONS) Russian patent published in 2005 - IPC

FIELD: seed production, in particular, equipment for presowing treatment of seeds of different kinds of farm crops.

SUBSTANCE: according to first and second versions, apparatus has drum mounted for free rotation on rollers disposed in bearings on bed. Axes of rotation of rollers are extending in parallel with axis of rotation of drum. Drum is manufactured from radio wave transmitting material with low loss value, such as polystyrene, and has thickness multiple t_side=λ/2√ε_s. According to first version, end walls of apparatus are manufactured from current conductive material, such as aluminum alloys, or from dielectric material with plated inner surface. Inner surface of drum walls is made ribbed, with height of ribs being multiple λ/4 and width of ribs and rib spacing being substantially lower than λ/2. According to second version, end walls of drum are made from current conductive material. Grid adjoining inner side of each end wall is composed of metal conductors extending in parallel with one another and end surface of drum. Distance from grid to inner end surface of drum is multiple t_e=λ/2√ε_e.

EFFECT: reduced treatment time, increased efficiency and simplified construction.
