METHOD OF MICROWAVE TREATMENT OF FEED GRAIN Russian patent published in 2015 - IPC A23L3/01 

FIELD: agriculture.

SUBSTANCE: device comprises a loading dispenser, a microwave chamber, a magnetron, a waveguide, a receiving hopper, a microprocessor. Inside the microwave chamber there is a device to move the grain from the bottom upwards, provided with a vertical screw, on the outer surface of which on the height the small guiding truncated cones are fixed, directed upwards with the small diameter. On the inner surface of the microwave chamber on the height the large guiding truncated cones are mounted, directed downwards with the small diameter. The angle of slope of the cone surface relative to the vertical axis is 42-45°. The annular gap δ₁ between the lower edge of the large guiding truncated cone and the outer conical surface of the small guiding truncated cone, and also the gap δ₂ between the lower edge of the small guiding truncated cone and the inner conical surface of the large guiding truncated cone are equal and are 25-30 mm. All parts located inside the microwave chamber are made of dielectric.

EFFECT: invention enables to improve the quality of treatment of feed grain over a wide range of agricultural processes, to reduce the metal consumption and specific energy consumption.
