Description

Technical Field

[0001] This utility model relates to the field of Pu'er tea processing technology, and in particular to a fermentation rack for Pu'er tea processing. Background Technology

[0002] Pu-erh tea is a fermented tea originating from Yunnan Province, China. It is famous for its unique taste, aroma, and health benefits. Through a special fermentation process, Pu-erh tea has the characteristics of mellow sweetness and rich aged aroma. Fermentation is a key step in the production of Pu-erh tea, which determines its quality and flavor. During the fermentation process, a Pu-erh tea fermentation rack is used to assist in the fermentation.

[0003] A search revealed that Chinese Patent Publication No. CN 217218041U discloses a fermentation rack technology for Pu'er tea processing, comprising a base with a water storage tank and a heating tube inside. A cabinet is mounted on one side of the upper surface of the base, and humidification ports are located on both sides of the bottom of the cabinet. A motor is mounted at the bottom of the cabinet, and a rotating rod is connected to the rotor shaft of the motor. Mounting plates are mounted on both sides of the rotating rod, and a placement box is mounted on the upper surface of both mounting plates. Ventilation ports are located at both ends of the placement box, and a placement container is placed inside the placement box. A sterilization lamp and a heating plate are mounted on one side of the inner wall of the cabinet, and a temperature and humidity sensor is mounted on the other side of the inner wall of the cabinet.

[0004] Typical Pu-erh tea fermentation racks are equipped with an air circulation system on the outside of the cabinet or box to ensure a relatively balanced temperature and humidity inside. The air circulation system circulates air between the top and bottom of the box to maintain the same level of heating for the Pu-erh tea placed on the top and bottom of the fermentation rack. However, these fermentation racks usually use a water tank for heating and humidification at the bottom. The water tank acts as a heat source, radiating outwards. As a result, even with air circulation, the temperature and humidity at the bottom of the box are still higher than at the top, leading to uneven heating. Therefore, a fermentation rack for Pu-erh tea processing is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of a fermentation rack for processing Pu'er tea, comprising a box body 1, which secures an internal feeding mechanism 4 to provide stability and maintain a certain temperature and humidity level unaffected by external factors. A heating mechanism is located at the lower end of the box body 1, and a door panel 3 is hinged to the front end of the box body 1, isolating the internal space from the outside. A latch is provided at the connection between the door panel 3 and the box body 1 when closed, providing stability when the door panel 3 is closed. A heat circulation mechanism is located at the right end of the box body 1, and an exhaust vent 12 is provided at the upper end of the box body 1 to allow air exchange between the internal space and the outside, ensuring the internal temperature and humidity are maintained. With sufficient oxygen, a canopy 5 is fixedly connected to the upper end of the chamber 1 to prevent foreign objects from falling directly into the chamber 1 through the exhaust port 12. A sliding mechanism is provided on the inner wall of the chamber 1. The heating mechanism includes a base 2, which contains a water tank to simultaneously heat and humidify the heat-dissipating pipe 14. The heat-dissipating pipe 14 is fixedly connected to the inner wall of the base 2. The heat-dissipating pipe 14 is a copper tube with multiple bends to maximize its contact area with the water tank, thus improving the heat dissipation effect. A control platform 15 is fixedly connected to the front end of the base 2. This control platform 15 is existing technology and can control the power supply of the entire device, maintaining the internal heat-dissipating pipe 14 at a constant temperature. The plate 10 reaches the corresponding temperature, and the heat dissipation pipe 14 is a common existing technology that only provides heating. A constant temperature plate 10 is fixedly connected to the inner wall of the box 1 to keep the inner wall temperature of the box 1 constant, heating when the temperature is low, and preventing excessive temperature difference between the upper and lower spaces inside the box 1. A sterilization lamp 11 is fixedly connected to the inner wall of the box 1. This sterilization lamp 11 is existing technology and is used to sterilize bacteria and prevent tea leaves from spoiling due to bacterial growth. A temperature and humidity monitoring meter 8 is fixedly connected to the right side of the box 1. This temperature and humidity monitoring meter 8 is existing technology and is used to monitor the temperature and humidity inside the box 1 for easy observation and adjustment of the control platform 15. In this section, a motor 9 is fixedly connected to the right end of the housing 1. This motor 9 is existing technology. The motor 9 will drive the connected components to rotate. The heat circulation mechanism includes a blower 6, which is existing technology. The blower 6 drives the air flow by rotating the internal blades. The lower end of the blower 6 is fixedly connected to the base 2. The upper end of the blower 6 is fixedly connected to a ventilation pipe 7. The left end of the ventilation pipe 7 is fixedly connected to the right end of the housing 1. The ventilation pipe 7 communicates with the housing 1. When the blower 6 is started, it will drive the air heated and humidified by the water storage tank at the bottom of the housing 1 to the upper end of the housing 1 through the ventilation pipe 7, so that the internal temperature and humidity of the housing 1 are relatively balanced.

[0035] Reference Figure 4 , Figure 5The inner wall of the box 1 is provided with a feeding mechanism 4, which includes a rotating bracket 401. The rotating bracket 401 ensures that each pile of tea leaves placed in the placement box 402 receives uniform temperature and humidity as it rotates, preventing uneven fermentation due to inconsistent temperature and humidity inside the box 1. The outer walls at both ends of the rotating bracket 401 are rotatably connected to the inner wall of the box 1, providing a stable fixing function. A fixing rod 404 is rotatably connected to the inner wall, providing a stable fixation effect for the placement box 402 on the rotating bracket 401. An anti-slip pad is provided at the connection between the fixing rod 404 and the rotating bracket 401, ensuring that the fixing rod 404 will only rotate under external force within the rotating bracket 401. The outer wall of the fixing rod 404 is rotatably connected to the placement box 402. The placement box 402 has a top-rounded, bottom-rounded design, allowing the turning leaf 405 to adhere to the lower inner wall of the placement box 402 when turning the tea leaves. The lower end of the placement box 402... The upper part of the placement box 402 is heavier than the upper part, ensuring that the semicircular part of the placement box 402 always faces downwards regardless of how the rotating bracket 401 is rotated. The upper part of the placement box 402 is hinged with a mesh cover, allowing tea leaves to be placed inside after opening the mesh cover. The tea leaves can be poured out by manually rotating the placement box 402 after opening the mesh cover. The mesh cover connects the space inside the placement box 402 with the interior of the box body 1, allowing for air circulation. The right end of the rotating bracket 401 is fixedly connected to the output end of the motor 9, and the motor 9 drives the rotating bracket 401. 1. Rotation: The outer wall of the fixed rod 404 is fixedly connected to a turning blade 405. When the fixed rod 404 rotates, it will drive the turning blade 405 to rotate, so that the turning blade 405 turns the tea leaves in the placement box 402. The left end of the fixed rod 404 is fixedly connected to a gear 403. The sliding mechanism includes a gear ring 13. The front end of the gear ring 13 is fixedly connected to a locking tooth. The outer wall of the locking tooth meshes with the outer wall of the gear 403. The meshing of the locking tooth with the gear 403 drives the fixed rod 404 to rotate.

[0036] Reference Figure 6 , Figure 7The left side of the housing 1 has a sliding groove 19. The right end of the gear ring 13 is fixedly connected to a sliding piece 18, allowing the sliding piece 18 to pass through the housing 1 and be fixedly connected to the gear ring 13. The outer wall of the sliding piece 18 is slidably connected to the inner wall of the sliding groove 19, restricting the sliding piece 18 to move only laterally. The left end of the sliding piece 18 is fixedly connected to a sliding block 17. The outer wall of the sliding block 17 is slidably connected to the right side of the housing 1. The sliding block 17 ensures that the sliding piece 18 will always be in close contact with the sliding groove 19, regardless of its position within the groove, preventing the housing 1 from being connected to the outside through the sliding groove 19. The temperature and humidity inside the box 1 are kept stable. The inner wall of the sliding block 17 is hinged with a push rod 16, so that pushing the push rod 16 will drive the sliding block 17 to move. A groove 20 is provided on the left side of the box 1. The outer wall of the push rod 16 is engaged with the inner wall of the groove 20. There are two sets of grooves 20. When the push rod 16 is engaged with one set of grooves 20, the position of the gear ring 13 is fixed. When the rotating bracket 401 rotates, it will drive the gear 403 to mesh with the locking teeth, causing the fixed rod 404 to rotate. When the push rod 16 is engaged with the other set of grooves 20, the gear 403 will not mesh with the locking teeth.

[0037] Working principle: Pu-erh tea needs to ferment under certain humidity and temperature. The tea leaves to be fermented are placed in the placement box 402, the door panel 3 is closed, and the control platform 15 is turned on to heat the tea. The heat pipe 14 heats the water in the base 2 to heat and humidify the inside of the box 1. The blower 6 circulates the gas at the bottom through the ventilation pipe 7 to the gas at the top, so that the temperature and humidity inside the box 1 are balanced. When the humidity reaches a certain level, the heat pipe 14 is turned off, the constant temperature plate 10 is turned on to stabilize the internal temperature, and the sterilization lamp 11 is turned on to kill bacteria. When the internal temperature and humidity are insufficient, the heat pipe 14 is turned on again to repeat the cycle. The rotating bracket 401 rotates inside the box 1, so that the temperature and humidity of each pile of tea leaves in the placement box 402 are more even.

[0038] After the tea leaves have fermented for a certain number of days, they need to be turned over. Push rod 16 is disengaged from groove 20 and pushed to engage gear 403 with the teeth on gear ring 13. Then push rod 16 is engaged with another set of grooves 20 to fix gear ring 13. When rotating bracket 401 rotates, when it reaches the position of gear ring 13, gear 403 drives the connected fixed rod 404 to rotate, thereby turning the tea leaves with turning blades 405. This allows the tea leaves to be turned over automatically by the internal turning blades 405 when they need to be turned over, without having to remove the tea leaves and turn them over again.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
