The invention discloses drum-type low-speed airflow tobacco material drying test equipment and a drying method thereof; the drying test equipment comprises supporting legs, wherein a box body is fixedly connected to the supporting legs; a support frame is arranged on the upper part of the box body for supporting a shred storage drum; a movable guide plate is arranged inside the lower part of the box body; the lower part of the box body is connected to one end of a heater; the other end of the heater is connected to an air duct; and an axial flow fan is arranged inside the air duct. The drum-type drying equipment is small in volume and small in occupied area, and the drying equipment is capable of replacing manual operation and is more suitable for drying materials on a small scale. The drum-type drying equipment, in coordination with a turning plate inside, is capable of drying materials with good uniformity, and the dried materials is relatively uniform in moisture. Through the design of the movable guide plate, the drying test equipment not only can guarantee the maximum airflow drying area but also can bring about benefit for cleaning the bottom of the box body. The drying test equipment is relatively wide in air drying temperature selection range, relatively low in airflow speed, relatively good in moisture uniformity of dried tobacco shred, relatively low in damage ratio and relatively good in experimental effect.
