[0002] Tea leaf killing is a step in the tea-making process that destroys and passivates the oxidase activity in fresh tea leaves through high temperature, inhibits the enzymatic oxidation of tea polyphenols in fresh leaves, evaporates part of the moisture in fresh leaves, softens the tea leaves, and facilitates rolling and shaping. At the same time, it emits a green smell and promotes the formation of a good aroma. It is one of the primary processing steps for green tea, yellow tea, black tea, oolong tea, etc., and tea leaf killing is a key step in the formation of the shape and quality of green tea.

[0003] Most of the existing tea withering machines are of drum type. Tea leaves are put into the drum and turned over by the rotation of the drum. However, the tea leaves put into the drum are mainly concentrated at the bottom of the drum. After the tea leaves come into contact with the drum, they can receive more heat. Even if the drum rotates, the tea leaves can only move within a small part of the drum, resulting in less heat received by the tea leaves, which reduces the withering efficiency. Therefore, in order to solve the above technical problems, the utility model provides a tea withering machine for tea processing. Utility Model Content
