MICROWAVE CONVECTIVE DRYER OF RAW MATERIALS WITH TIERED TOROIDAL RESONATORS Russian patent published in 2023 - IPC F26B15/26 F26B3/347 

FIELD: agriculture.

SUBSTANCE: invention can be used for drying bulk raw materials. During the transportation of raw materials, a loading tank, three-tiered cavity resonators and a receiving tank are installed. The resonators are made in the form of straight prisms joined together by their faces, forming the toroidal and condenser parts of the resonators. A perforated ceramic tube is laid through the condenser parts of the resonators, inside which a dielectric screw with perforated turns is installed, which are made of non-ferromagnetic material under the loading tank, at the level of the prism faces joining, and above the receiving tank. Through the side faces of the prisms, dielectric air ducts from heat guns are connected to the perforated ceramic tube. On the upper faces of the prisms there are air outlets in the form of transcendental waveguides. On the side faces of the prisms there are air-cooled magnetrons with waveguides, whereas the magnetron emitters are directed into the condenser gap of the resonators.

EFFECT: increased uniformity of drying.
