It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides a Pu'er tea fermentation production line, such as Figure 1-4As shown, the Pu'er tea fermentation production line includes: a support frame 1, on which a reciprocating motor is installed; a plurality of driving rollers 2, which are rotatably installed on the support frame 1, and any one of the driving rollers 2 is fixedly connected to the output shaft of the reciprocating motor; a conveyor belt 3, which is movably sleeved on the plurality of driving rollers 2; a fermentation barrel 4, which is placed on the top of the conveyor belt 3, and in which an isolation plate 5 is provided, on which a sewage pipe extending to the outside of the fermentation barrel 4 is installed, and a solenoid valve is provided on the sewage pipe; a temperature and humidity sensor 13, which is arranged on one side of the fermentation barrel 4, and a detection head of the temperature and humidity sensor 13 extends into the fermentation barrel 4; a humidification component, which is arranged on the support frame 1, and is used to humidify the fermenting Pu'er tea.
[0022] In this embodiment, the support frame 1 is the foundation of the entire production line. It stably carries various key components and ensures the stable operation of the production line. The driving roller 2 and the conveyor belt 3 constitute the main power transmission part of the production line. The driving roller 2 drives the conveyor belt 3 to move through the drive of the reciprocating motor, thereby realizing the continuous transportation of the fermentation barrel 4 on the production line. The fermentation barrel 4 is the main place for Pu'er tea fermentation. The isolation plate 5 inside it can divide the fermentation barrel 4 into different areas to meet different fermentation needs, and the drain pipe is used to discharge the waste liquid generated during the fermentation process. The solenoid valve can control the discharge of the waste liquid to make the operation more convenient. The temperature and humidity sensor 13 monitors the temperature and humidity environment in the fermentation barrel 4 in real time, providing the operator with accurate data reference, so that the fermentation conditions can be adjusted as needed.
[0023] In a further preferred embodiment of the utility model, the humidifying assembly includes a water tank 6, a hot water pump 7, a drain pipe 8 and a spray head 9, the water tank 6 is fixedly mounted on the support frame 1, the hot water pump 7 is arranged in the water tank 6, the drain pipe 8 is fixedly mounted at the discharge end of the hot water pump 7 and extends to the outside of the water tank 6, the spray head 9 is mounted at the discharge end of the drain pipe 8, and a liquid replenishing pipe is provided on the top of the water tank 6.
[0024] In this embodiment, the water tank 6 is used as a container for storing humidification water, and its stability and capacity are guaranteed. The hot water pump 7 draws water from the water tank 6 to provide power for the humidification process. The drain pipe 8 ensures that the water can be smoothly transported from the water tank 6 to the spray head 9. The spray head 9 is the core component of the humidification component. When the hot water pump 7 is started, the water is pumped to the drain pipe 8 and finally sprayed out from the spray head 9 in the form of mist, evenly covering the Pu'er tea in the fermentation barrel 4, thereby achieving the humidification effect. This mist humidification method can better control the humidity, so that the Pu'er tea can be fermented in a more uniform and suitable humidity environment.
[0025] In a further preferred embodiment of the utility model, an exhaust pipe 14 is rotatably mounted on the isolation plate 5, a plurality of branch pipes 17 are mounted on the exhaust pipe 14, the plurality of branch pipes 17 are all located above the isolation plate 5, a fixing block 15 is rotatably sleeved on the bottom of the exhaust pipe 14, a fan 16 is fixedly mounted on the bottom inner wall of the fermentation barrel 4, an exhaust end of the fan 16 is fixedly connected to the fixing block 15, a dustproof net 20 is provided on the fermentation barrel 4, exhaust ports are provided at the bottoms of the plurality of branch pipes 17, and partition nets are provided in the plurality of exhaust ports.
[0026] In this embodiment, a gas discharge network covering the interior of the fermentation barrel 4 is formed by the cooperation of the exhaust pipe 14 and the branch pipe 17. When the fan 16 is turned on, the gas drawn in by the fan 16 is discharged through the branch pipe 17, thereby achieving uniform discharge of the gas inside the fermentation barrel 4. The dustproof net 20 can effectively prevent external dust and other impurities from entering the fermentation barrel 4, thereby ensuring the cleanliness of the Pu'er tea fermentation environment. The exhaust port is combined with the partition net to ensure smooth gas discharge and prevent Pu'er tea or other impurities from entering the exhaust pipe 14 and the branch pipe 17 through the exhaust port.
[0027] In a further preferred embodiment of the utility model, two limit plates 23 are installed on the support frame 1, and the two limit plates 23 are respectively located on both sides of the fermentation barrel 4, and a plurality of balls 24 are inlaid on the sides of the two limit plates 23 close to each other, and the plurality of balls 24 can contact the outer wall of the fermentation barrel 4.
[0028] In this embodiment, the two limiting plates 23 form a stable support and limiting structure to prevent the fermentation barrel 4 from easily tipping over. The design of the ball bearings 24 allows them to be in close contact with the outer wall of the fermentation barrel 4. When the fermentation barrel 4 moves on the conveyor belt 3, the ball bearings 24 can reduce the friction between the fermentation barrel 4 and the fermentation barrel 4, making the movement of the fermentation barrel 4 smoother.

[0030] In this embodiment, when the servo motor 18 is started, it can drive the exhaust pipe 14 and the branch pipe 17 thereon to rotate through the transmission of the bevel gear 19, so that the gas circulation and discharge in the fermentation barrel 4 can be controlled more accurately and flexibly, and at the same time, the Pu'er tea leaves can be stirred to further increase the heat dissipation effect.
[0031] In a further preferred embodiment of the utility model, a temperature sensor is provided in the water tank 6, a metal box 10 is fixed on an inner wall of one side of the water tank 6, a plurality of heating wires 11 are provided in the metal box 10, and a retaining ring 12 for preventing sewage leakage is fixedly installed on the support frame 1.
[0032] In this embodiment, the temperature sensor can detect the water temperature in the water tank 6 in real time to ensure that the temperature of the humidification water is within an appropriate range. At the same time, the heating wire 11 can be started when needed to heat the water in the water tank 6, thereby ensuring that the temperature of the humidification water is always maintained in an appropriate state. During the humidification and sewage discharge process, some sewage or wastewater will be generated. The retaining ring 12 can effectively block the sewage or wastewater within the range of the support frame 1 to prevent it from leaking to other parts.
[0033] In a further preferred embodiment of the utility model, a limiting ring 21 is fixedly installed in the fermentation barrel 4, and a moisturizing plate 22 is placed on the limiting ring 21. The moisturizing plate 22 is composed of a support ring and cotton gauze. The support ring is placed on the top of the limiting ring 21, and the cotton gauze is installed in the support ring.
[0034] In this embodiment, the limiting ring 21 not only plays the role of fixing and supporting, but also ensures that the moisturizing plate 22 added subsequently is stably placed in the fermentation barrel 4. The supporting ring ensures the stability of the moisturizing plate 22. Since the cotton gauze has good moisture absorption and air permeability, it can effectively maintain the humidity of Pu'er tea and avoid fermentation problems caused by excessive moisture.
