MOBILE MICROWAVE-CONVECTIVE CONTINUOUS-FLOW HOP DRYER WITH SEMI-CYLINDRICAL RESONATORS Russian patent published in 2023 - IPC C12C3/02 F26B3/347 F26B15/04 

FIELD: agriculture.

SUBSTANCE: invention can be used in hop-growing farms for the gradual drying of freshly harvested hops in a continuous mode while maintaining consumer properties. The mobile microwave-convective continuous-flow hop dryer with semi-cylindrical resonators comprises resonators 1, 4, 7 formed by non-ferromagnetic semi-cylinders equal in size, length and diameter multiple of half the wavelength, docked with the side surfaces, and located under them through the gap of the working branches of the corresponding non-ferromagnetic mesh conveyors 11, 23, 28 of different lengths. Inside each half-cylinder, ceramic plano-convex half-disks 18, 22, 27 are attached to the facade bases, and air ducts 17, 21, 26 from heat guns are connected under idle branches of non-ferromagnetic mesh conveyors. Non-ferromagnetic air outlets 3, 6, 9 with non-ferromagnetic exhaust fans are attached to the rear bases of the half-cylinders, and magnetrons 2, 5, 8 are installed with a shift of 90 degrees along the generatrix of each resonator. Idle branches of non-ferromagnetic mesh conveyors are placed in non-ferromagnetic tray 14 with nozzle 12 for a vacuum cleaner. In the gaps between the joints of the forming semi-cylinders and the working branches of the mesh conveyors, non-ferromagnetic cellular agitators 16, 19, 24 are installed along their width with a cell depth of not more than two depths of wave penetration into hop cones. Non-ferromagnetic loading tank 10 is installed along the side surface of the first non-ferromagnetic resonator, and receiving tank 29 is installed under the last conveyor. The whole hop dryer, together with the heat guns and the control cabinet, is placed on a trolley.

EFFECT: hop dryer ensures the preservation of consumer properties of dried and disinfected hops in the process of multi-stage drying.
