DRYING METHOD OF DISPERSE (BULK) MATERIALS INSIDE VERTICALLY INSTALLED CYLINDRICAL CAPACITY, BOTTOM OF WHICH IS HEATED FROM OUTSIDE WITH DIRECTIONALLY FOCUSED EMISSION IN NEAR-INFRARED REGION Russian patent published in 2015 - IPC F26B3/20 F26B3/30 F26B11/10 

FIELD: heating.

SUBSTANCE: bottom or the whole capacity is mesh-like or perforated, thus heating by radiation the bottom from below or/and the bottom from below, and side surface on the outside along a generatrix to the specified temperature, thus rotating the capacity relative to its axis. Material being dried is continuously filled inside a hollow fixed pipe that is installed vertically and coaxially inside the capacity with a uniform gap; material is moved downwards to the centre of the heated bottom. Then, on its surface to edges and then in an upward direction between a cylindrical wall of the rotating capacity and the external surface of the fixed pipe, and near the upper edge of the capacity the material is captured with a suction flame of a pneumatic transporting device and the dried material is continuously removed from the capacity.

EFFECT: invention is intended to implement continuous and high-efficiency drying of bulk materials.
