Description

Technical Field

[0001] The invention relates to the technical field of tea production, in particular to tea production equipment based on tea fermentation. Background Art

[0002] Tea fermentation is a crucial step in traditional Chinese tea-making, particularly crucial in the production of dark tea, oolong tea, black tea, and other varieties. Fermentation is essentially an oxidation process, where controlled humidity and temperature cause a series of changes in the chemical composition of the tea leaves, resulting in a unique flavor. Existing tea fermentation machines use spiral blades to transport the tea leaves, causing them to tumble within the conveyor. However, this technology does not allow for rolling the tea leaves, requiring them to be rolled after removal from the conveyor. This makes the operation more inconvenient and the fermentation process more cumbersome and complex, making it difficult to scale production.

[0003] To this end, the Chinese patent publication number "CN119279036A" discloses "a tea production device based on tea fermentation", whose main structure includes a conveying cylinder, a support shaft, a rotating member, a first sleeve, a second sleeve, and a spiral auger. The two ends of the spiral auger are respectively fixed to the periphery of the first sleeve and the second sleeve, and when the first sleeve moves toward the second sleeve, the spiral auger will produce telescopic deformation along the axial direction of the support shaft. The spiral surface of the spiral auger is fixed with ridges. By setting the second sleeve to move toward the first sleeve, the spiral auger will be compressed, thereby gathering the tea leaves between the spiral augers. The rotating member drives the support shaft to rotate, so that the spiral auger stirs the tea leaves. At the same time, the ridges set on the spiral surface of the spiral auger will produce a kneading effect on the tea leaves, and there is no need to knead the tea leaves after discharging, simplifying the operation steps and making tea processing capable of large-scale production.

[0004] However, in the actual production process, the above-mentioned tea production equipment based on tea fermentation drives the tea in a direction through a rotating spiral auger. At the same time, the spiral surface of the spiral auger will cause the tea leaves around it to move in a direction (similar to screw feeding). Since the two ends of the spiral auger are closed spaces, the tea leaves will be squeezed in a direction at this time. The squeezing will increase the torque of the equipment and crush the tea leaves. Therefore, it is easy to cause the quality of the finished tea products to decline. Summary of the Invention

When the horizontal fermentation cylinder 31 rotates, the tea inside the horizontal fermentation chamber 32 is automatically rolled up and down. Under the action of body gravity and the friction of the horizontal fermentation cylinder 31, a flipping phenomenon will occur.
