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

FIELD: technological processes.

SUBSTANCE: device includes vertically installed cylindrical casing, which external surface 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 the form of flat spring, on which rigidly connected to it and equipped with drive perforated plate of round shape, heating element, as well as fan and air duct. Transporting working member is multisectional with possibility of rotation in one direction and arrangement of sections one above another, note here that flat springs winding direction of every next section is opposite to that of flat spring of previous section. 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 ensures reduction of grain drying process duration.
