[0001] The utility model relates to the technical field of screening equipment, in particular to a drying and screening device for tea leaves. Background Art

[0002] White tea is a key processed traditional Chinese tea, known for its fragrance, sweetness, and strong floral and fruity aroma. To produce high-quality processed white tea, drying is a crucial step, which can help the tea leaves to be fully exposed to the sun and reduce the growth of bacteria. In order to ensure the dryness of the tea leaves, they need to be turned every day.
