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

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, 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 in the longitudinal vertical plane is oval. 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. Box is divided horizontally into two equal parts. In the upper part of the box, on its inner lower side, heating elements are installed, the surface of which, which is not adjacent to the box, is covered with a layer of heat-insulating material. Air duct is connected to the lower part of the box. Lower parts of the box and the casing are perforated. Unloading window is equipped with a gate and is located on the lower part of the casing under the loading hopper.

EFFECT: higher quality of grain drying.
