Description

technical field [0001] The invention relates to a black tea fermenting device, more specifically to a fully automatic black tea fermenting device, which belongs to the field of tea processing machinery. Background technique [0002] The most important chemical change in the production of black tea is that tea polyphenols are oxidized by oxygen in the atmosphere under the catalysis of oxidase. This process is the fermentation of black tea. Therefore, fermentation is an extremely critical link in the production process of black tea. Only good fermentation can form more theaflavins and thearubigins, and more taste and aroma substances can be formed; if the fermentation process is not well mastered, it will have a great impact The quality of black tea. Humidity, temperature and oxygen content are the three elements to ensure the quality of black tea fermentation. At present, the external environment required for fermentation is mainly maintained by building a fermentation room,...
