Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea drying technology, specifically a tea dryer with a multi-layer drying structure. Background Technology
[0002] Tea drying machines typically involve spreading tea leaves on one or more layers of drying equipment, then turning on electric heating devices for drying. In the tea processing industry, drying is a crucial process that determines the quality of tea, and the design of the turning structure directly affects the drying effect and the integrity of the tea leaves. Traditional tea drying machines often use rigid stirring blades or scrapers to turn the tea leaves to ensure that the tea leaves are in full contact with the hot air and achieve uniform drying.
[0003] In the process of achieving the above, the inventors discovered at least the following problems with this technology: Some existing tea dryers use a rigid turning method to tumble the tea leaves during drying. This rigid turning method has certain drawbacks. During the turning process, the rigid components come into direct and frequent contact with the tea leaves, which can easily lead to the breakage, curling, and deformation of the buds and leaves, seriously affecting the appearance and commercial value of the tea. Therefore, we propose a tea dryer with a multi-layer drying structure. Utility Model Content

With the cooperation of the support rod, the lifting plate can drive the tea leaves on the drying and ventilation mesh tray to move up and down reciprocally. Due to inertia and gravity, the tea leaves will slide and roll relatively within the drying and ventilation mesh tray, thereby turning the tea leaves over and allowing them to fully contact the hot air during the drying process, thus improving the uniformity of drying.

[0025] 2. During the drying process, the temperature sensor can monitor the internal temperature of the base and transmit the signal to the controller. When the temperature exceeds the set value, the controller can control the fan to start and cool the inside of the base. Attached Figure Description
