[0070] Specifically, when the first driving member drives the cylinder 41 to rotate alone, the heating structure 5 can heat the cylinder 41. When the first driving structure 3 and the first driving member work together, they can drive the cylinder 41 to swing up and down and rotate. The heating structure 5 can also heat the cylinder 41, which can be beneficial to the uniform mixing of tobacco, more uniform heating, and improved drying efficiency.

[0071] The heating coil 52 is wound around the outer circumference of the barrel 41 and is located in the heating space formed between the heat preservation barrel 51 and the outer wall of the barrel 41. The heat preservation barrel 51 is provided with a heat preservation layer inside to reduce the heat loss during heating, and can protect the heating coil 52 to prevent electromagnetic leakage, thereby improving the safety of the heating coil 52 when in use.
