GRAIN DRYING DEVICE Russian patent published in 2019 - IPC F26B17/26 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to grain drying devices. Grain drying device comprises a casing, the outer surface of which is covered with a layer of heat-insulating material, a loading hopper, an unloading window, a heating element, fan, air duct and transporting working body, made in the form of a tray of heat-conducting material. Tray is installed to impose vibration on elastic elements. Heating elements are installed on the lower side of the transporting working body. In the lower part of the casing, on the side opposite to the hopper, a cooling column is vertically installed, inside of which on the side walls perforated plates are located, and the size of the holes in the plates does not exceed the minimum grain size. Perforated plates are installed at an angle that is not less than the angle of natural slope of grains. Unloading window is installed in the lower part of the cooling column. Air duct is installed at the bottom of the cooling column. Lower part of the wall of the unloading window is made perforated with the size of the holes not exceeding the minimum grain size. Transporting working body is installed with a slope in the direction of the cooling column. Upper part of the casing above the cooling column is perforated.

EFFECT: technical result is the improved grain drying quality.
