Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a fermentation machine. Background Art

[0002] Tea fermentation is a simple oxidation process, which causes a series of biochemical changes in fresh tea leaves. Tea fermentation is actually a process of polyphenol enzyme oxidation reaction. Currently, during the tea fermentation process, a tea fermentation machine is often used to ferment tea.

[0003] For example, the Chinese utility model patent (CN217906121 U) discloses a tea fermentation machine, which records: "By setting cross-shaped paddles on the first connecting rod, the second connecting rod and the third connecting rod in the box, and the motor drives the cross-shaped paddles on the first connecting rod, the second connecting rod and the third connecting rod to rotate through gears and racks, the paddles will turn over the tea, so that the fermentation degree of the tea is uniform, preventing the tea at the bottom from being perfectly fermented and affecting people's use. And because of this device, a large amount of labor cost for turning over the pile is saved."

[0004] However, when the box body of the above fermentation machine is closed, the overall structure adopts a fixed sealing structure, which leads to insufficient oxygen during the fermentation process on the one hand, so the final product is not fresh enough; on the other hand, since there is a step of spraying fermentation water during the tea fermentation process, the fermentation water cannot flexibly enter and exit the sealed box body, affecting the tea fermentation effect. Therefore, this application proposes a fermentation machine. Summary of the Utility Model
