Description

technical field

[0001] The invention relates to the technical field of tea production equipment, in particular to a drum-type tea degreening device. Background technique

[0002] Tea greening is to destroy and passivate the oxidase activity in fresh tea leaves by high temperature, inhibit the enzymatic oxidation of tea polyphenols in fresh leaves, evaporate part of the water in fresh leaves, make tea soft, easy to knead and shape, and emit green odor at the same time Taste, a tea-making step that promotes the formation of a good aroma.

[0003] Traditional tea greening machines have long working hours and low work efficiency. During greening, the tea leaves are heated unevenly, and the greening effect is not ideal. For example, Chinese patent CN107774559U discloses a hot air circulation type tea greening screening device, which drives hot air through hot air circulation fan blades. Circulation is carried out so that the tea leaves in the equipment are evenly heated, but the...
