LOOSE GRAIN MATERIALS DRYING DEVICE Russian patent published in 2017 - IPC F26B11/14 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Grain drying device includes cylindrical casing 1, loading bin 3, discharge opening 4, air duct 6 and fan 12. Heating elements 9 are arranged on casing 1 outer surface under heat-insulating material 2 layer between loading bin 3 and discharge opening 4. Inside casing 1 coaxially with possibility of rotation transporting screw 5 is arranged with hollow shaft and perforated turns 19 with perforation diameter, not exceeding minimum grain size. Casing is made compound. Casing 1 component parts are separated by rings 8 from heat-insulating material. In air duct 6 between casing 1 and fan 12 heating element 11 is arranged. Casing 1 is installed on supports 7 with possibility of its inclination angle varying relative to horizontal line and fixation in specified position. Inside screw 5 hollow shaft there perforated cup 18 is arranged. On screw 5 hollow shaft inner surface perforated turns are made with pitch, equal to outer turns 19 pitch.

EFFECT: increasing device operation efficiency due to more complete use of its inner volume.
