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

FIELD: manufacturing technology.

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. Conveying working element is made multi-sectioned with arrangement of sections above each other, besides, direction of coiling of flat springs of each next section is made opposite to direction of coiling of flat spring of the previous section. Between the sections of the transporting working element there is an unloading pipe rigidly connected to flat springs, 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. Perforated plate of upper section is rigidly connected with flat spring, and perforated plates of next sections are rigidly connected to casing and covered with heat-insulating material.

EFFECT: invention ensures reduction of grain drying process duration.
