PORTABLE MICROWAVE CONVECTION UNIT FOR DRYING AND DISINFECTING GRAIN Russian patent published in 2021 - IPC A01F25/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to drying and disinfection of grain in closed rooms, in various containers or stored in the form of a pile on open currents. The portable microwave convection installation contains a rigid tubular structure with openings in the lower part, the upper part of which is connected to a confuser having a flange connection with a blower diffuser of an electrically driven fan. The lower end of the tubular structure is made tapering and is equipped with an air baffle and a two-way screw-type screw. Inside the upper part of the rigid tubular structure made of metal, there is a magnetron with a microwave reflector and a power supply. The power supply unit and magnetron are installed in such a way that the air flow from the fan cools their cases, providing the possibility of heating the air flow supplied by the fan from the magnetron, its power supply unit and from a metal tubular structure heated by microwave radiation, as well as heating and disinfecting grain through the holes in a metal tubular structure with heated air and a microwave field.

EFFECT: invention allows increasing efficiency and speed of grain drying, ensures grain disinfection due to the use of microwave radiation from a magnetron, and to reduce post-harvest grain losses.
