[0025] Referring to Figs. 1-3Specifically, a gearbox 3 is installed on the spray dryer body 1. One end of the gearbox 3 is inserted into the spray dryer body 1, and the other end of the gearbox 3 is inserted out of the spray dryer body 1. One end of the drive rod 21 is rotatably connected to the gearbox 3 inside the spray dryer body 1. A drive component 311 is installed on the gearbox 3 outside the spray dryer body 1. The output end of the drive component 311 is inserted into the gearbox 3 and connected to the drive wheel 31. A driven wheel 32 is sleeved on the drive rod 21 inside the gearbox 3. A transmission component 33 is provided between the drive wheel 31 and the driven wheel 32. The drive component 311 can drive the drive wheel 31 to rotate, and the driven wheel 32 can drive the drive rod 21 to rotate. Through the transmission of the transmission component 33, the drive wheel 31 and the driven wheel 32 can rotate synchronously, so that the drive component 311 can drive the drive rod 21 to rotate.

[0026] See Figs. 1-3 Specifically, both the driving wheel 31 and the driven wheel 32 can be sprockets, and the transmission component 33 is a chain, which improves transmission efficiency.

[0027] See Figs. 1-3 Preferably, since the dispersing mechanism 2 and the gearbox 3 are located inside the spray dryer body 1, waterproof or sealing measures should be taken for the dispersing mechanism 2, the gearbox 3, and the dispersing mechanism 2 and the gearbox 3.
