CROSS-REFERENCE TO RELATED APPLICATION
This patent application claims the benefit and priority of Chinese Patent Application No. 202311329653.X, filed with the China National Intellectual Property Administration on Oct. 16, 2023, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.
TECHNICAL FIELD
The present disclosure relates to the technical field of tea leaves processing, in particular to a multi-layer fermentation tank for tea leaves, and a use method thereof.
BACKGROUND
The fermentation of tea is an important link in the process of tea processing. In the prior art, fermentation tank is mostly used to ferment tea leaves, and the tea leaves are stacked in the fermentation tank. However, the tea leaves at the lower layer are inadequately fermented due to less contact with oxygen. A multi-layer fermentation device for tea leaves as disclosed in China patent CN219422086U includes a tank body. Both inner walls of a tank body are provided with chutes, sliders are slidably connected in to both chutes, and a placement plate is fixedly connected to each of opposite surfaces of the two sliders. A support column is fixedly connected above the placement plate, and a fermentation box is fixedly connected above the support column. According to the patented technology, multiple fermentation boxes arranged up and down are arranged in the tank body, and a stirring structure for stirring tea leaves is placed in each fermentation box to solve the problem that the tea leaves at the lower layer are inadequately fermented when the tea leaves are stacked. The defects of the above patented technology are as follows: (1) the multi-layered placement plates can divide the tank body into several parts which are independent from each other up and down, making the gas mobility in the whole tank body poor. (2) Each fermentation box needs to be equipped with a stirring structure, leading to complicated overall structure and inconvenient laying of tea leaves in the fermentation box.
