[0002] White tea is one of the six major types of tea in China. It is a slightly fermented tea with a fermentation degree of 5%-15%. White tea is loved by people for its unique production process and quality characteristics. The production process of white tea includes the main steps of picking, withering and drying. Among them, withering is the key step in forming the quality of white tea. By controlling the speed and degree of water loss of tea leaves, the transformation of tea leaves' contents is promoted to form the unique flavor of white tea. After the tea leaves are withered, the staff needs to place the tea leaves in a drying box for drying.
[0003] For example, Chinese patent CN210809097U discloses a tea drying box, in which tea leaves that have been rolled and sorted are evenly spread on trays, horizontal boards are arranged at intervals in the oven, and then the trays are placed on the horizontal boards and stacked from the lower layer to the higher layer in the oven, thereby drying the tea leaves.
[0004] Most drying boxes store tea leaves on trays. In order to ensure that the tea leaves at the bottom of the tray can be completely dried, the staff needs to manually adjust the density and thickness of the tea leaves on the tray after placing the tea leaves, thereby avoiding the tea leaves from being piled too thick or too dense. The tea leaves at the bottom may not be completely dried because the heat cannot fully penetrate. When the amount of tea to be dried is too much, the staff needs to frequently adjust the tea leaves on the tray, which is time-consuming and laborious. When the working time is too long, the staff will inevitably become tired, which reduces work efficiency. Therefore, this utility model is proposed to solve the above problems. Utility Model Content
