Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a processing device for tea fermentation. Background Art

[0002] Tea, a beverage made from the tender buds and leaves of the tea plant, is widely enjoyed for its rich taste and health benefits. The tea production process includes multiple steps, including picking, withering, rolling, fermentation, and drying. Fermentation is a key step in determining tea quality.

[0003] Tea fermentation is the process by which microorganisms and enzymes alter the composition of tea leaves, creating their unique aroma and flavor. The degree of fermentation directly affects the tea's final taste and quality.

[0004] In the prior art, tea fermentation typically involves placing the tea leaves directly into a fermentation vat and then heating and humidifying them. However, this method presents certain challenges: the tea leaves accumulate within the vat, resulting in uneven heat and humidity distribution, which affects the uniformity of fermentation. Furthermore, after fermentation is complete, the tea leaves are difficult to remove, increasing the complexity and labor intensity of the operation. Furthermore, due to incomplete fermentation, it can take longer to achieve the desired effect.

[0005] In order to solve these problems, there is an urgent need for a new type of fermentation device that can improve tea distribution, enhance fermentation uniformity and facilitate removal, so as to improve tea production efficiency and quality. In view of this, we propose a processing device for tea fermentation. Utility Model Content
