[0004] Although the prior art 1 can screen tea debris by rotating the screening cylinder, the tea leaves tend to gather together to form a tea pile during its rotation. In a short period of time, only the debris on the outer side of the tea pile can be screened and removed, while it is inconvenient to screen and remove the debris on the inner side of the tea pile, which affects the screening efficiency of the tea debris.
