Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a drum-type tea fixing device for tea production. Background Technology

[0002] Tea fixation is a tea-making process that uses high temperatures to destroy and deactivate the oxidase activity in fresh tea leaves, inhibit the enzymatic oxidation of tea polyphenols and other substances in the fresh leaves, evaporate some of the moisture in the fresh leaves, soften the tea leaves, make them easier to roll and shape, and at the same time remove the grassy smell and promote the formation of a good aroma.

[0003] Existing tea fixation processes involve tumbling and heating the tea leaves in a heating drum. However, during tumbling, the tea leaves tend to pile up after falling, resulting in uneven heating and affecting the fixation effect. To address this, we propose a drum-type tea fixation device for tea production. Utility Model Content
