[0002] Fermentation is a key process in tea processing to form quality. Fermentation is a series of chemical changes mainly involving the oxidation of polyphenol compounds in tea leaves under certain temperature and humidity conditions due to the promotion of enzymes. The existing fermentation devices have a slow fermentation speed and cannot turn over the tea leaves. Therefore, a tea fermentation device is disclosed in Chinese Patent Publication No. CN213992301U. The device drives a stirring shaft to rotate through a motor to turn over and stir the tea leaves inside, thereby improving oxidation efficiency and ensuring the adequacy of fermentation while accelerating fermentation.

[0003] However, the traditional tea fermentation temperature is generally low, and traditional equipment mostly uses electric heating plates for heating. This heating method is difficult to control the temperature and is very likely to cause overheating and damage the tea polyphenols inside the tea. Therefore, those skilled in the art provide a temperature-adjustable tea fermentation device to solve the problems raised in the above background technology. Utility Model Content
