[0014] The present invention provides a tea fermentation device for tea processing, which has the following beneficial effects: (1) The tea fermentation device for tea processing makes it easier to take out tea leaves through the coordinated operation of a rotating rod, a sliding frame, a discharge frame, a fixed rod, a sleeve, a connecting plate, a U-shaped plate, a roller, a telescopic spring rod, a fixed block, a receiving plate, a receiving block, and a sleeve. The tea leaves are pushed into the device when the device starts working, which reduces the labor intensity of the operator. At the same time, the automatic entry and exit simplifies the operation process, makes it easy to disassemble and clean, and reduces the impact of residues on subsequent operations. At the same time, the discharge frame is prevented from shifting during operation, which reduces the operation accidents caused by mechanical wear due to improper position adjustment.

[0015] (2) The tea fermentation device for tea processing realizes layered fermentation of tea leaves of different sizes through the coordinated operation of the receiving tube, the scraper, the second telescopic elastic rod, the support frame, the third telescopic elastic rod, the fixed plate, the receiving tube, the round plate, the long plate, the convex block, and the fourth telescopic elastic rod, thereby ensuring that each layer of tea leaves is fermented under suitable conditions to improve the fermentation efficiency. Through layered fermentation, the fermentation degree of different tea leaves can be better controlled, thereby improving the quality of the tea leaves. At the same time, through the up and down swinging, the tea leaves of different sizes can be better layered, so that each layer of tea leaves is in uniform contact during the fermentation process. The up and down swinging can prevent the tea leaves from piling up, thereby avoiding the tea leaves from being compacted during the fermentation process and affecting the fermentation efficiency.

[0016] (3) The tea fermentation device used for tea processing realizes air circulation through the coordinated operation of the air outlet frame, the filter plate, the pressure rod, the ventilation pipe, the mobile frame, the handshake, and the ventilation port. Appropriate air circulation helps to control the fermentation temperature and humidity. Air circulation can accelerate the fermentation process and improve production efficiency. At the same time, it prevents moisture accumulation from causing the tea to mold. At the same time, when the gas generated by the tea fermentation circulates, it is absorbed by the sachet. When it is necessary to check whether the tea is well fermented, the handshake is pulled open to drive the mobile frame to be pulled open. By smelling the gas on the sachet, it can be determined whether the tea is fully fermented. The fermentation process of the tea is monitored in real time. Through odor detection, there is no need to pull out the discharge frame. Only the mobile frame needs to be pulled out to observe whether the tea is fully fermented through the sachet.
