[0004] Based on the above, when the tea leaves move in the mesh drum, some of the tea leaves will be stuck in the grid of the mesh drum, causing discharge residue, affecting the discharge effect of the dryer, and this part of the tea leaves becomes very dry after being dried for a long time. Other tea leaves will collide with these dry tea leaves when passing by, causing these dry tea leaves to be crushed and discharged together with the debris, causing a waste of tea leaves and affecting the use effect of the dryer.
