APPARATUS FOR DISINFECTING AND SHELLING GRAIN IN SUPER-HIGH-FREQUENCY ELECTROMAGNETIC FIELD Russian patent published in 2016 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to grain processing enterprises technological equipment and is intended for disinfecting and shelling. Apparatus has vertically positioned on mounting frame cylindrical shielding housing with intake and discharge branch pipes, serving as cutoff waveguides. Inside housing coaxially located dielectric perforated cylinder and hollow shaft to make circular gap. On shaft fitted in toroidal resonators with round cross-section. Tore consists of rings and connected hollow annular disc. Between sectors rings made of non-ferromagnetic material and coated with outer side of abrasive material, there are dielectric rims. Maximum clearance between rims of less than quarter wavelength, but larger than thickness of grain. On outer side of housing are arranged evenly along height of microwave generator units with radial shift. Radiators in spherical segment are located at level of toroidal resonators and directed with their lateral side. Number of microwave generators is less than or equal to number of toroidal resonators. Hollow vertical shaft, in places of landing hollow circular discs drilled several radial holes. At bottom on shaft are installed fan blades. Shaft mounted on bearings, driven by motor located on the mounting frame. One discharge pipe to discharge finished product is connected with annular gap. Second discharge pipe to remove husks is connected with annular gap between shielding housing and dielectric perforated cylinder at level of fan blades. Intake pipe is installed on cover of shielding housing. Well head is mounted on cover connected with hollow shaft to adjust air access.

EFFECT: higher quality of the obtained product.
