Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a black tea fermentation device with uniform stirring. Background Art

[0002] Black tea belongs to the category of fully fermented tea. It is made from the buds and leaves of tea trees through typical processes such as withering, rolling, fermentation, and drying. Because the color of its dry tea and the brewed tea soup are mainly red, it is called black tea. In the processing of black tea, fermentation is a unique stage in the production of black tea. After fermentation, the color of the leaves changes from green to red, forming the quality characteristics of red leaves and red soup of black tea. The mechanism is that under the action of rolling, the cell membrane structure of the leaves is destroyed, the permeability increases, and the polyphenols are fully in contact with the oxidase, and oxidative polymerization occurs under the action of the enzyme. Other chemical components also undergo profound changes accordingly, causing the green tea leaves to turn red, forming the color, aroma and taste quality of black tea. At present, fermentation machines are commonly used to control the temperature and time for fermentation. When the fermentation is moderate, the color of the young leaves is evenly red, the old leaves are red with a hint of green, the grass smell disappears, and it has the aroma of ripe fruit.

However, when turning and stirring, there is a gap between every two leaf levelers, and the tea leaves in the gap are difficult to be turned and stirred, which affects the turning and stirring effect. In addition, the position of the hopper is fixed, which is inconvenient to take the fermented tea leaves and is not convenient to use. In view of the shortcomings of the prior art, the utility model discloses a black tea fermentation device with uniform turning and stirring to solve the above problems. Utility Model Content
