[0002] The fermentation of tea leaves is to destroy the tea leaves so that the chemical substances in the tea leaves will oxidize with the air, producing a certain color, taste and aroma. By controlling the degree of fermentation, the tea leaves can have different colors, aromas and flavors. In the process of tea making, from killing green leaves, indoor withering, stirring, fermentation is always in progress. According to the different degrees of fermentation, from light to heavy, they are green tea, white tea, yellow tea, oolong tea, black tea, and black tea. As for the color of the tea soup, it is because the degree of oxidation of tea polyphenols in the tea leaves is different, and the order from light to dark is the same as above.
[0003] When in use, the load-bearing bracket and the fermentation box of the existing tea fermentation device are mostly an integrated structure or fixed by bolts. Generally, when fermenting tea, it may not be necessary to process too much tea at one time, resulting in uneven distribution of the load-bearing tray inside the tea fermentation device; the existing tea fermentation room mainly uses fixed fermentation racks, which have limited space, and the preparatory work such as placing tea leaves in the early stage of tea fermentation is mainly completed manually, and it is inconvenient to take and put tea leaves, which is time-consuming and labor-intensive, and has low work efficiency. In addition, when the tea leaves are piled up, the contact area with oxygen is relatively small, resulting in a long fermentation time. Summary of the invention
