Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to a production line of Chinese cabbage Pu'er tea. Background Art

[0002] The production process of Pu'er tea is unique and complicated. Among them, the withering device is crucial in Pu'er tea production. Withering destroys the enzyme activity in tea leaves through high temperature to prevent oxidation of tea leaves and maintain the freshness and greenness of tea leaves. This link not only affects the color, aroma and taste of tea leaves, but also is related to its subsequent aging and storage.

[0003] The patent with application number CN202410713276.8 discloses a dried ginger Pu'er tea production line, including a fermentation device, the fermentation device including a fermentation chamber for storing tea leaves, the fermentation chamber is provided with: a heat dissipation ventilation mechanism, for inputting airflow into the fermentation chamber to dissipate heat from the fermentation chamber; a humidity control mechanism, the humidity control mechanism is connected to the heat dissipation ventilation mechanism, for inputting dry airflow into the heat dissipation ventilation mechanism to reduce the humidity of the fermentation chamber during the heat dissipation process of the heat dissipation ventilation mechanism, and for inputting humid airflow into the heat dissipation ventilation mechanism to increase the humidity of the fermentation chamber during the heat dissipation process of the heat dissipation ventilation mechanism.

[0004] However, traditional tea-frying equipment lacks automation mechanisms, and the turning and uniform heating of the tea leaves rely on manual operations, which is labor-intensive and difficult to ensure the consistency and effect of the tea withering. Although the drum tea withering machine has achieved a certain degree of mechanization, due to the different moisture levels of the tea leaves and the consistent passing time in the drum, some tea leaves are over- or under-withered. At the same time, in traditional tea production lines, additional drive equipment is required to cooperate with conveyor belts for transportation of the tea leaves after they are green, which increases the complexity and cost of the equipment, and there is a risk of damage or contamination of the tea leaves.
