[0002] Tea is a traditional drink. Most teas are made from fresh buds and leaves of tea trees, and are made into drinkable dry leaves through processes such as withering, rolling, and drying.

[0003] In order to separate the lightness, heaviness, thickness and thinness of tea leaves, and to remove yellow flakes, tea dust and other non-tea light inclusions in the tea leaves, most people currently use tea winnowing machines. The tea leaves are put into the machine body through the feed port, and the centrifugal fan or suction fan installed in the machine body generates wind speed to achieve the effect of separating the tea leaves.

[0004] At present, when feeding tea leaves, most people directly put a large amount of tea leaves into the machine through the feed port. Although this method is simple and quick, it is easy to cause accumulation and mutual interference between the tea leaves, making it difficult for wind to penetrate the tea layer, thus affecting the accuracy and effect of sorting.
