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

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to the agricultural machine building. Device for drying grain comprises a vertically installed cylindrical casing, outer surface of which is coated with a layer of heat-insulating material, loading hopper, 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, heating element, as well as fan and air duct. Conveying working element is made multi-sectioned with arrangement of sections above each other and possibility of rotation of each next located below flat spring in direction opposite to the previous flat spring. Between the sections of the transporting working element there is a discharge branch pipe, which is made perforated with the size of holes, which does not exceed the minimum grain size. Air duct is installed perpendicular to the discharge branch pipe. Unloading opening and discharge branch pipe of odd sections are located at the center of bottom of transporting working element, and unloading opening and discharge branch pipe of even sections are located on periphery of lower part of transporting working element.

EFFECT: invention allows to reduce duration of grain drying process.
