FIELD: heating.
SUBSTANCE: plant material drying device includes a drying chamber having a heat carrier supply channel and a drum screen located in the chamber and installed on the rotation axis. The heat carrier supply channel to the chamber is made at a tangent to side surface of the drum screen on the side opposite to the drum rotation direction, and side surface of the drum is equipped with vanes installed with inclination to that surface in the rotation direction side. The heat carrier supply channel is equipped on the inner side of the drying chamber with one or several nozzles.
EFFECT: reduction of drying time; reduction of heat energy costs and improvement of the device efficiency.
