DEVICE FOR GRAIN DRYING Russian patent published in 2020 - IPC A23B9/08 

FIELD: technological processes.

SUBSTANCE: device includes a vertically installed cylindrical casing, which external surface is covered with a layer of heat-insulating material, a loading hopper, an unloading window, coaxially installed inside casing with possibility of rotation transporting working element, made in form of flat spring, on which is rigidly connected to it and equipped with drive perforated plate of round shape, a heating element, as well as a fan and an air duct. Conveying working element is multi-sectional. Sections are arranged above each other so that flat springs located in underlying sections are installed with minimum clearance between their upper edge and lower edge of heating element of upper section. Branch pipe is arranged between odd and even sections in casing center. Perforated rings made of heat-conducting material are installed above heating elements. Air duct is installed from below the casing along its center, and the lower part of the casing is perforated.

EFFECT: invention ensures reduction of grain drying process duration.
