DEVICE FOR GRAIN DRYING Russian patent published in 2009 - IPC F26B11/14 

FIELD: agriculture.

SUBSTANCE: device for grain drying includes cylindrical casing, whose external surface is covered with the layer of heat-insulating material, heating elements, placed on external surface of casing under the layer of heat-insulating material between loading bunker and delivery opening, loading bunker, delivery opening, coaxially installed inside casing with possibility of rotation transporting working element, air duct and ventilator. Transporting working element is made in form of worm whose flights are made perforated with perforation diametre not exceeding minimal grain size. Casing is made composite, constituent parts of casing being separated with each other by means of rings made from heat-insulating material. Air duct is connected with internal cavity of casing, is located between loading bunker and delivery opening at equal distance from them and is installed perpendicular to casing. In air duct between casing and ventilator heating element is installed. Casing is installed on supports with possibility to change angle of its inclination relative to horizontal line and fixation in set position, and after ventilator installed is branch pipe with possibility to place filter inside it.

EFFECT: increase of treated grain quality, efficiency and versatility of device, reduction of energy consumption and emissions of harmful substances into environment.
