Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to a tea withering machine for evenly withering tea leaves. Background Art

[0002] Tea withering 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 the fresh leaves, evaporates part of the moisture in the fresh leaves, softens the tea leaves, and facilitates rolling and shaping, while also emitting a green smell and promoting the formation of a good aroma.

[0003] Existing tea leaf fixing machines mostly use drum-type fixing machines, which directly heat the drum and then transfer heat to the tea leaves. The fixing machine of this method has the problem of uneven heating. When more tea leaves are put into the machine, the color and aroma of the tea leaves will be seriously affected, and the quality of tea making will be reduced. At present, steam fixing is mostly used for tea leaf fixing. Although steam fixing can maintain the color of tea leaves, a lot of water will adhere to the surface of tea leaves after fixing, which affects the quality of tea leaves. In addition, tea leaves are piled up together, resulting in insufficient fixing, uneven fixing, and different quality of tea leaves in the same batch. For this reason, those skilled in the art have proposed a fixing machine for tea leaves with uniform fixing to solve the problems raised in the above background. Summary of the invention
