DOMESTIC DRYING MICROWAVE OVEN Russian patent published in 2014 - IPC H05B6/64 

FIELD: heating.

SUBSTANCE: domestic drying microwave oven includes a magnetron with an electric power supply and control system, a housing with a waveguide, a working chamber with raw material flanges, at least one of the walls of which has air passage perforation, an exhaust fan with a diffuser and an individual circuit breaker. Larger base of the diffuser is connected to the perforated wall of the working chamber, and surface area of perforated wall surface, which is enveloped with the diffuser, is 0.5-1.0 of the cross sectional area of the working chamber; according to the invention, at least two electrodes from non-magnetic metal are installed into the working chamber and attached by means of dielectric insulators to the working chamber. One electrode is a cathode, made from a metal mesh with small cells and located parallel to upper wall of the working chamber under a dissector, and the second electrode being an anode is made from a metal perforated plate and parallel to the working chamber lower wall.

EFFECT: intensifying a drying method of capillary-porous raw material of plant origin in microwave ovens due to electrokinetic phenomena occurring at superimposition of a DC electric field onto the drying object.
