[0018] Example 1
[0019] like Figure 1 and Figure 3As shown, a uniform fermentation device for black tea includes a fermentation cylinder 1 for storing tea leaves, facilitating subsequent fermentation. A temperature and humidity sensor 15 is installed at one end of the fermentation cylinder 1 to monitor the internal temperature and humidity in real time, allowing for timely adjustments by staff to improve fermentation efficiency and quality. Both ends of the fermentation cylinder 1 are rotatably connected to rings 2, which support and position the cylinder, preventing it from deviating from its intended position during rotation. A humidification structure 8 is provided on the upper surface of one of the rings 2, including a support plate 801 fixedly connected to one side of one of the rings 2. The support plate 801 is supported and positioned to prevent it from being suspended in mid-air. A water tank 802 is fixedly connected to the upper surface of the support plate 801 to store water. A high-pressure water pump 803 is fixedly connected to the upper surface of the support plate 801. The input end of the high-pressure water pump 803 is fixedly connected to a first delivery pipe 804, one end of which is connected to the inside of the water tank 802. The output end of the high-pressure water pump 803 is fixedly connected to a second delivery pipe 805. The high-pressure water pump 803 converts the water in the water tank 802 into water mist. When the humidity inside the fermentation tank 1 is too low, the humidity inside the fermentation tank 1 is increased by the water mist. When the humidity inside the fermentation tank 1 is too high, the water mist is evaporated by the heating pipe 13 to regulate the humidity inside the fermentation tank 1. The second conveying pipe 805 and the adapter 10 work together to deliver water mist into the interior of the second support rod 704. One end of the second conveying pipe 805 is fixedly connected to the adapter 10, which facilitates the entry of water mist and air into the interior of the second support rod 704. A first support frame 6 is fixedly connected to the side of one of the rings 2, and a fan 11 is fixedly connected to the side of the first support frame 6. One end of the fan 11 is fixedly connected to a third conveying pipe 12, and one end of the third conveying pipe 12 is fixedly connected to one side of the adapter 10. The fan 11 and the third conveying pipe 12 work together to operate the interior of the second support rod 704. The fan 11 pushes the water mist inside the second support rod 704 to the bottom of the second support rod 704. When the temperature inside the fermentation tank 1 is too high, it can be controlled by... A fan delivers natural air to cool the inside of the fermentation cylinder 1. A heating element 13 is installed on the inner wall of the fermentation cylinder 1, and a power supply 14 is installed at the bottom of the fermentation cylinder 1. One side of the power supply 14 is electrically connected to one end of the heating element 13. The power supply 14 and the heating element 13 work together to change the temperature inside the fermentation cylinder 1, preventing the temperature from becoming too low and affecting the fermentation of the black tea. When the temperature inside the fermentation cylinder 1 is too high, the temperature of the heating element 13 is reduced. The temperature inside the fermentation cylinder 1 can also be lowered through the oxygen port 16. A stirring structure 7 is installed inside the fermentation cylinder 1. The stirring structure 7 includes a servo motor 701 fixedly connected to one side of the first support frame 6. The output end of the servo motor 701 supports the first gear 702 and drives the first gear 702 to rotate.A first gear 702 is fixedly connected to the output end of a servo motor 701. A second gear 705 is meshed with the outer side of the first gear 702 and fixedly connected to the outer side of a second support rod 704. The second support rod 704 is hollow to facilitate the flow of water mist and air. The first gear 702 drives the second gear 705, the second support rod 704, and the stirring rod 706 to rotate, stirring the black tea inside the fermentation tank 1 to make the black tea more evenly distributed and facilitate subsequent fermentation. The stirring rod 706 is fixedly connected to the outer side of the second support rod 704, and the stirring rod 706 has multiple holes. The perforation allows water mist from inside the second support rod 704 to be sprayed onto the surface of the black tea during stirring by the stirring rod 706, thus regulating the humidity inside the fermentation cylinder 1. The second support rod 704 is located inside the fermentation cylinder 1, and its top is rotatably connected to one side of the adapter 10. A gear ring 703 is fixedly connected to one end of the fermentation cylinder 1. The outer side of the first gear 702 is fixedly connected to the inner side of the gear ring 703. The interaction between the first gear 702 and the gear ring 703 drives the fermentation cylinder 1 to rotate. The fermentation cylinder 1 rotates in the opposite direction to the second support rod 704, which allows the black tea inside the fermentation cylinder 1 to be distributed more evenly.
[0020] like Figure 2 As shown, a second support frame 9 is fixedly connected to one side of the first support frame 6, supporting the second support frame 9 to prevent it from being suspended. One side of the second support frame 9 is fixedly connected to one side of the adapter 10, supporting the adapter 10 to prevent it from being suspended. An oxygen port 16 is provided at one end of the fermentation cylinder 1 for oxygen exchange, allowing the black tea inside the fermentation cylinder 1 to ferment better. A filter screen is installed on one side of the oxygen port 16 to block the tea leaves inside the fermentation cylinder 1, preventing them from falling out during rotation. The filter screen also removes external impurities. A filter screen is used to block the tea leaves from entering the fermentation cylinder 1. The fermentation cylinder 1 has a material inlet on the side for feeding and discharging. A cover 4 is installed on the material inlet to seal it during the fermentation of black tea, preventing the loss of humidity and temperature inside the fermentation cylinder 1. A handle 5 is fixedly connected to one side of the cover 4 for easy removal. A first support rod 3 is fixedly connected to the side of the ring 2. There are two rings 2 located at both ends of the fermentation cylinder 1, and the number of rings 2 can be set according to the actual situation. The rings 2 and the first support rod 3 work together to support the fermentation cylinder 1 and prevent the fermentation cylinder 1 from directly contacting the ground.
[0021] It should be noted that this uniform fermentation device for black tea supports the fermentation cylinder 1 through the cooperation of the first support rod 3 and the ring 2. The material is filled into the fermentation cylinder 1 through the material inlet. After filling, the material inlet is sealed with the cover 4. The servo motor 701 drives the first gear 702 to rotate, which in turn drives the second gear 705, the second support rod 704, and the stirring rod 706 to rotate, thus stirring the material inside the fermentation cylinder 1. The rotation of the first gear 702 also drives the gear ring 703 and the fermentation cylinder 1 to rotate, preventing material from accumulating at the bottom of the fermentation cylinder 1. The humidity and temperature inside the fermentation cylinder 1 are monitored by the temperature and humidity sensor 15, and the process is carried out under high pressure. The water pump 803 input end and the first delivery pipe 804 work together to draw water from the water tank 802. The high-pressure water pump 803 output end, the second delivery pipe 805 and the adapter 10 work together to deliver water mist to the inside of the second support rod 704. The water mist is sprayed into the fermentation cylinder 1 through the holes on the stirring rod 706. The fan 11 and the third delivery pipe 12 work together to deliver the water mist to the inside of the second support rod 704. The power supply 14 and the heating pipe 13 work together to regulate the temperature inside the fermentation cylinder 1. Oxygen is delivered through the oxygen port 16. The tea leaves inside the fermentation cylinder 1 are blocked by the filter screen to prevent them from falling out of the fermentation cylinder. When the black tea fermentation is complete, it is output through the material port.
[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
