[0003] The hot air drying machine for tea leaves in the prior art mainly heats the air through a heating furnace, and then uses a blower to directly send the hot air into the drying chamber. The tea leaves are spread flat on the screen and dried by hot air. The tea leaves are stationary, which will cause the tea leaves at different positions to be heated to different degrees. The uneven heating of the tea leaves will cause the quality of the finally dried tea leaves to be uneven, thus reducing the quality of the tea leaves.

[0004] In the existing equipment, a front or rear dispersing device is also provided to disperse the tea leaves.
