GRAIN DRYING DEVICE Russian patent published in 2022 - IPC F26B17/04 F26B3/34 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly, to grain drying devices. Grain drying device comprises a casing, the surface of which is coated with a layer of heat-insulating material, inside the casing there is a transporting working element in the form of an endless chain with scrapers, loading hopper, unloading window, heating elements, box installed inside casing, as well as cooling device consisting of fan and air duct. Box is made of heat-conducting material and oval in longitudinal vertical plane. Inner surface of the casing follows the contours of the box; at that, the distance from the inner surface of the casing to the outer surface of the box is constant and equal to the height of the scrapers of the transporting working element. Height of scrapers and distance between scrapers of transporting working element are equal to maximum size of grain. Heating elements are installed on the inner side of the upper and lower parts of the box. Air duct of the cooling device is installed on the side of the casing. Casing wall located opposite to the air duct is perforated. Unloading window is located on the lower part of the casing under the loading hopper.

EFFECT: higher quality of grain drying.
