Description

Technical Field

[0001] The utility model relates to the field of tea processing equipment, in particular to a black tea fermentation device which is convenient for cleaning residues. Background Art

[0002] Black tea is the young leaves or buds of the tea plant of the Theaceae family. Black tea does not grow naturally. Instead, it was made on the basis of green tea in the late Ming and early Qing dynasties. It is made from suitable new tea shoots of the tea tree as raw materials and is refined through a series of technological processes such as withering, rolling, fermentation, and drying. The fermentation process causes chemical reactions in the components of the tea leaves. When brewed with water, it not only has a pleasant aroma but also presents a unique deep red tea color, so it is called black tea.

[0003] At present, during the processing of black tea, a black tea fermentation device is needed to ferment the tea leaves. However, the traditional black tea fermentation device does not have a cleaning function. As a result, after the black tea is taken out of the black tea fermentation device after fermentation, the black tea residues remaining inside the black tea fermentation device need to be manually cleaned by the operator, which increases the workload of the operator and at the same time reduces the efficiency of the black tea fermentation device for fermenting the next batch of black tea.
