[0001] The invention belongs to the technical field of tea cleaning, and in particular relates to a cleaning device for tea processing and a use method thereof. Background Art

[0002] Cleaning in tea processing refers to the process of cleaning fresh leaves or semi-finished tea leaves during the primary or refined process of tea. This is because tea leaves are prone to carry mud, dust, insect feces, residual tiny impurities (such as weed debris), etc. after being picked from the tea garden. It also contains pesticide residues. The core purpose of cleaning is to remove impurities and dirt attached to the surface of the tea leaves, and at the same time provide a clean raw material basis for subsequent processing links.

[0003] Traditionally, when cleaning tea leaves, fresh tea leaves are poured into a water tank and stirred manually to achieve the purpose of cleaning the tea leaves. However, there are many shortcomings in the cleaning process: during the tea cleaning process, manpower is consumed for stirring, and after cleaning, the tea leaves need to be picked up from the water tank by manpower, which is inefficient. If multiple cleanings are required, the water needs to be replaced, and the tea leaves need to be frequently picked up and poured in, which greatly increases the cleaning time and the workload of the staff. Therefore, improvements are needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, when cleaning tea leaves, it is necessary to use manpower to pick up the tea leaves from the water tank. If cleaning is repeated multiple times, the water needs to be replaced and the tea leaves need to be frequently picked up and poured in, which greatly increases the workload of the workers and is inefficient.
