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

FIELD: agriculture.

SUBSTANCE: grain drying device comprises a vertical casing made in the form of a cylinder, the outer surface of which is covered with a layer of heat-insulating material, a loading hopper, a discharge window, a conveying working member coaxially mounted within the casing with the possibility of rotation, and a cooling device consisting of a fan and an air duct. The transporting working member is made in the form of a flat perforated spring. The height of the flat perforated spring is equal to the maximum size of the grain to be dried. The loading hopper is installed above the flat perforated spring at its outer edge. The width of the discharge window of the loading hopper is equal to the distance between the adjacent coils of the multi-threaded flat perforated spring. A plate of the circular shape is installed on the multi-threaded flat perforated spring, rigidly connected thereto and equipped with a drive. The plate radius does not exceed the distance from the center of the multi-threaded flat perforated spring to the discharge window of the loading hopper. The heating element is placed under the transporting working member and is made in the form of a flat ring, the outer diameter of which is equal to the inner casing diameter, and the inner diameter of the flat ring is equal to the inner coil diameter of the multi-threaded flat perforated spring. The discharge window is made circular-shaped and is installed coaxially to the casing under the heating element. The discharge window diameter is equal to the inner diameter of the flat ring. The air duct of the cooling device is connected to the inner casing cavity from opposite lateral sides.

EFFECT: use of the invention will allow to improve the quality of grain drying and to reduce energy costs.
