[0002] Tea is a beverage ingredient made from the fresh leaves of the tea tree. The tea making process includes picking, withering, rolling, fermentation and baking steps, which eventually form the different types of tea we are familiar with. In the production and processing of tea, screening is an important link. It can help producers remove stems, impurities and fragments in tea leaves and improve the overall quality and taste of tea. The purpose of screening is to remove impurities and irregular particles in tea leaves, make the shape and size of tea leaves more uniform, and improve the quality and appearance of tea leaves.

[0003] Common tea screening is usually done by manually pouring the tea into the sieve and shaking the sieve for screening. In actual operation, the operator may not be able to ensure the uniform and appropriate amount of tea, resulting in uneven distribution of the tea during the screening process, making it difficult to ensure the accuracy of screening. After multiple screenings, tea residues may be blocked at the sieve opening. If they are not cleaned in time, the sieve may be blocked the next time screening is performed.

[0004] Therefore, the utility model provides a layered screening device to solve the problems raised in the above background technology. Utility Model Content
