The first wooden rotor is rotatably arranged at the center of the bottom wall. The first wooden rotor is transmission-connected to the driving mechanism. The second wooden rotor is transmission-connected to the first wooden rotor. The zinc powder drying bin is used to effectively store zinc powder. However, the stirring rod in the device can only stir the stored zinc powder in the horizontal direction.
