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

FIELD: agriculture.

SUBSTANCE: 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, heating member, and a cooling device consisting of a fan and an air duct. The conveying working member is made in the form of a flat spring. The height of the flat spring is equal to the maximum size of grain to be dried. The loading hopper is installed above the flat spring at its outer edge. The width of outlet window of the loading hopper is equal to the distance between adjacent coils of flat spring. A perforated plate of the circular shape, equipped with a drive, is installed on the flat perforated spring, rigidly connected thereto. The perforated plate radius does not exceed the distance from the center of flat spring to the outlet window of loading hopper. The heating member is placed under the conveying working member and is made in the form of a flat perforated ring, the outer diameter of which is equal to the inner casing diameter, and the inner diameter of flat perforated ring is equal to the inner coil diameter of flat spring. The unloading 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 flat perforated ring. The cooling device air duct is connected to the perforation of heating element.

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