DEVICE FOR GRAIN DRYING Russian patent published in 2017 - IPC A23B9/08 F26B17/22 

FIELD: agriculture.

SUBSTANCE: device for grain drying comprises a vertical cylindrical casing, a loading hopper, a discharge window, a transporting working member coaxially mounted within the casing with the possibility of rotation, a heating element. The outer casing surface is covered with a layer of a heat-insulating material. The transporting working member is made in the form of a flat spring. The height of the flat spring is equal to the maximum size of the grain to be dried. The loading hopper is installed above the flat spring at its outer edge. The width of the outlet window of the loading hopper is equal to the distance between the adjacent coils of the flat spring. A perforated plate of the circular shape is installed on the flat perforated spring, rigidly connected thereto and equipped with a drive. The plate radius does not exceed the distance from the center of the flat spring to the outlet window of the loading hopper. On the surface of the perforated plate coaxially with it, a box of the circular shape is installed, the diameter of which is equal to the diameter of the perforated plate. An impeller is mounted inside the box on the drive shaft. The heating element is located under the transporting working member and is made in the form of a flat ring, whose outer diameter is equal to the inner casing diameter. The inner diameter of the flat ring is equal to the diameter of the inner flat spring coil. 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 box is provided with a branch pipe.

EFFECT: improved quality of grain drying.
