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

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular, to devices for drying grain. The device for drying grain contains a casing, the surface of which is covered with a layer of heat-insulating material, inside the casing there is a transporting working body in the form of an endless chain with scrapers, a loading hopper, an unloading window, heating elements, a box installed inside the casing, as well as a cooling device consisting of a fan and duct. The box in the longitudinal vertical plane is made oval. The inner surface of the casing repeats the contours of the box, and 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 body. The height of the scrapers and the distance between the scrapers of the transporting working body are equal to the maximum grain size. The box is divided horizontally into two equal parts, and heating elements are installed in the upper part of the box from its inner lower side, and an air duct is attached to the lower part of the box. The lower parts of the box and casing are perforated. The unloading window is equipped with a damper and is located on the lower part of the casing under the loading hopper.

EFFECT: quality of grain drying is improved.
