FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to grain drying devices. Proposed device comprises vertically installed cylindrical casing with outer surface coated with heat-insulating material layer, loading hopper, unloading opening, heating element and transporting working element coaxially installed inside casing with possibility of rotation. Conveying working element is made in the form of a flat spring, on which a perforated plate of a round shape is rigidly connected to it and equipped with a drive. 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 are installed above heating elements. Plate of round shape made of heat-conducting material is installed between transporting working element and heating element of lower section.

EFFECT: invention usage will allow to reduce duration of grain drying process.
