Installation for grinding and disinfecting grain and grain products in an electromagnetic field of ultra-high frequency

摘要

Installation for grinding and disinfecting grain and grain products, characterized in that it has a vertically arranged cylindrical shielding housing with a receiving hopper and an outlet pipe, inside of which, parallel to the bases, rotor disks of different diameters are located, rotating in opposite directions, between which there are cylindrical parts volume resonators mounted on the respective rotor disks along a peripheral concentric circle, and for the drive of the rotor disks correspondingly The motor gearboxes are mounted centrally on the outer side of the bases of the shielding housing, while on the shaft of the large-diameter rotor disk there is a screw with a window on its housing for the receiving hopper, and the base of the shielding housing made of non-ferromagnetic material and the rotor disk have ring holes, moreover microwave generator blocks are placed on the opposite base of the shielding case along the above concentric circles so that their emitters are directed inside spherical segments of volume resonators, while their cylindrical parts are formed from non-ferromagnetic pins of triangular cross-section, set by a gap of less than a quarter of the wavelength and greater than the thickness of the grains, and the number of spherical segments is much smaller than the number of cylindrical parts of the volume resonators, and their diameters are equal and consistent with the length waves, while the large-diameter disk is made of non-ferromagnetic material, and the small-diameter disk is made of fluoroplastic, the discharge pipe is located on the side surface of the cylinder Cesky
