Description

Technical Field

[0001] The invention relates to the field of tea processing, and more specifically to an all-in-one machine for fermenting black tea and yellow tea. Background Art

[0002] Yellowing is a unique process in the production of yellow tea. It refers to piling up the tea leaves after withering, rolling or initial baking, so that the tea leaves gradually turn yellow under the action of moisture and heat. According to the water content of the tea leaves, it can be divided into wet yellowing and dry yellowing. However, when the tea leaves are piled together, they tend to turn yellow unevenly.

[0003] Fermentation is an important step in the processing of black tea. However, the traditional method of tea fermentation is to pile the tea leaves together for natural fermentation. During fermentation, the tea leaves need to be turned over continuously to avoid excessive internal temperature of the tea leaves and ensure that the tea leaves can be evenly exposed to oxygen, and water needs to be sprayed in time. However, the existing fermentation device has a single function and cannot automatically roll the tea leaves repeatedly, and cannot spray the fermentation liquid on the falling tea leaves at the same time. It needs to be turned over manually, which is time-consuming and laborious, increases labor intensity, and easily leads to uneven fermentation and deterioration of tea quality. Summary of the invention

[0004] 1. Technical issues to be solved
