Description

Technical Field

[0002] The rainwater green tea dehumidification device is crucial to tea farmers' production, especially Wuyi rock tea. The tea picking season happens to be the plum rain season, and most of the picked tea leaves have a high moisture content. The picked tea leaves cannot be used for subsequent processing. Therefore, the rock tea rainwater green tea equipment can directly improve the production efficiency of tea farmers, and indirectly improve the quality of tea products and increase economic benefits.

[0003] Existing tea dehumidification devices are designed with the infrared dehumidification and withering principle.
