GRAIN DRYING DEVICE Russian patent published in 2017 - IPC A23B9/08 F26B17/28 

FIELD: agriculture.

SUBSTANCE: grain drying device includes the vertical cylindrical casing, the outer surface of which is covered with a layer of the heat-insulating material, the loading hopper, the discharge window, the transporting working element coaxially mounted within the casing with the possibility to rotate, the heating element, the outer surface of which is covered with a layer of the heat insulating material. The transporting working element is made in the form of a perforated flat spring. The hopper is mounted above the flat spring at its outer edge, the loading hopper outlet window width being equal to the distance between the adjacent coils of the flat spring. A round-shaped plate equipped with a drive is mounted on the flat perforated spring. The heating element is placed under the transporting working element and is made in the form of a flat ring, the outer diameter of which is equal to the inner diameter of the casing, and the inner diameter of the flat ring is equal to the inner coil diameter of the perforated flat spring. In the flat ring perforations, bushings made of the heat-insulating material are mounted. The discharge window is made circular-shaped and is installed coaxially under the heating element. The discharge window diameter is equal to the inner diameter of the flat ring. The cooling device air duct is connected to the perforation of the heating element.

EFFECT: improving the quality of grain drying, reducing the energy consumption.
