Description

Technical Field

[0001] This utility model relates to the field of Pu'er tea, and in particular to a constant temperature and humidity fermentation system for ripe Pu'er tea. Background Technology

[0002] Pu-erh tea is a unique type of tea from Yunnan Province, China. It is a post-fermented tea and is famous for its unique flavor and aging value. The raw material for Pu-erh tea is mainly the fresh leaves of Yunnan large-leaf tea trees. Through specific processing techniques, it is divided into two main types: raw Pu-erh and ripe Pu-erh. The fermentation process of ripe Pu-erh tea has a significant impact on its quality and flavor. The constant temperature and humidity fermentation system is an important piece of equipment to achieve this process. The core purpose of this system is to promote the pile fermentation of tea leaves under specific temperature and humidity conditions, so as to accelerate the maturation of ripe tea.

[0003] A search revealed Chinese Patent Publication No. CN217218039U, which discloses a constant temperature and humidity fermentation system for Gu Yun Pu'er ripe tea. The system includes a housing with an evaporation chamber located on the lower part of its inner wall. An electric heating element is installed at the bottom of the evaporation chamber. Rotating rods are rotatably mounted on both sides of the top of the evaporation chamber, with fan blades at the ends of the rotating rods inserted into the evaporation chamber. A fermentation chamber is located at the top of the housing, with a motor at its top. The motor's rotor shaft is connected to a support rod, on which a placement tray is mounted. A main gear is located at the bottom of the support rod, and secondary gears are installed at the ends of the rotating rods inserted into the fermentation chamber. The main gear meshes with the secondary gear. A flow hole is located at the top of the evaporation chamber. By activating the electric heating element, the water in the evaporation chamber is heated and evaporated. Simultaneously, the motor drives the main gear to mesh with the secondary gear, rotating the rotating rods and fan blades. Water vapor is discharged into the fermentation chamber through the flow hole, simultaneously rotating the placement tray, thus ensuring more even fermentation of the tea.

[0004] While the aforementioned device can heat and humidify the fermentation chamber using hot steam, the steam is transported from bottom to top. This can lead to more water vapor contact between the Pu-erh tea placed on the lower trays, resulting in a significant humidity difference between the lower and upper Pu-erh tea. Furthermore, since the fermentation temperature of Pu-erh tea is generally maintained between 20 and 50 degrees Celsius, and the required relative humidity is generally 60% to 80%, relying on steam for heating and humidification may result in excessively high fermentation temperatures or humidity levels. It also cannot individually control and adjust the temperature or humidity according to specific conditions, making it impractical. Therefore, a constant temperature and humidity fermentation system for ripe Pu-erh tea is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a constant temperature and humidity fermentation system for Pu'er ripe tea, including a housing 1 for connecting various components. A door 11 is hinged to the front of the housing 1 for easy installation and removal of the fermentation box 5. A control panel 12 is located at the front of the door 11, containing electronic components for controlling heating elements and other components. A temperature and humidity transmitter 4 is connected to the control panel 12 via wiring, transmitting detection results to its display. The control panel 12 has a display screen and buttons at its front. The buttons control other components via pre-set instructions from the control elements within the control panel 12. A heating element, which may be an electric heating element, is installed inside the housing 1 to regulate the temperature inside the housing 1. A motor 2 is fixedly connected to the bottom of the housing 1, driving the fermentation box 5 to rotate via a humidification pipe 3, allowing the tea leaves to ferment. To ensure more even heating, the output end of motor 2 is fixedly connected to a rotating shaft 21, which drives the humidification tube 3 to rotate. The rotating shaft 21 passes through the housing 1 and is rotatably connected to it. The rotating shaft 21 is fixedly connected to the bottom of the humidification tube 3. A humidification mechanism is set in the middle of the housing 1 to increase the humidity inside the housing 1. The humidification mechanism includes the humidification tube 3 and a first connecting pipe 6. The first connecting pipe 6 passes through the housing 1 and is fixedly connected to it. The first connecting pipe 6 is connected to a humidifier to humidify the inside of the housing 1. The lower part of the first connecting pipe 6 is rotatably connected to the humidification tube 3 to facilitate the delivery of humidified gas containing water vapor into the housing 1. At the same time, in conjunction with the rotation of the humidification tube 3, a second connecting pipe 7 is fixedly connected to the top of the housing 1 and is connected to a dehumidifier to reduce the humidity inside the housing 1. A temperature and humidity transmitter 4 is set inside the housing 1. This is existing technology, and a suitable model can be selected according to the requirements.

[0033] like Figure 3 - Figure 5As shown, multiple fermentation boxes 5 are provided on the outside of the humidification tube 3 for the fermentation of Pu'er tea. Multiple sets of humidification ports 31 are opened on the outer wall of the humidification tube 3, which are evenly opened around the outer wall of the humidification tube 3. Each set of humidification ports 31 has a spiral 32 below it, which is used to cooperate with the adjusting ring 331 in the threaded connection between the humidification tube 3 and the adjusting ring 331. A limiting member 33 is provided on the outside of the humidification tube 3, which cooperates with the limiting ring 34 to fix the position of the fermentation box 5. Multiple limiting rings 34 are fixedly connected to the outer wall of the humidification tube 3, which are set at the lower part of the fermentation box 5 to provide support for the fermentation box 5.

[0034] Furthermore, the limiting component 33 includes an adjusting ring 331, which is used to drive the positioning ring 332 to adjust its position, thereby driving the connection between the fixing rod 333 and the fixing groove 511. The adjusting ring 331 is threadedly connected to the humidification tube 3. The lower part of the adjusting ring 331 is rotatably connected to the positioning ring 332, which is used to cooperate with the connection of multiple fixing rods 333. The front part of the bottom of the positioning ring 332 is fixedly connected to multiple fixing rods 333, which are used to cooperate with the fixing groove 511 to fix the position of the fermentation box 5.

[0035] Furthermore, the fermentation box 5 includes a frame 51, which is used to cooperate with the mesh plate 53 for stacking materials. The rear part of the frame 51 is provided with a slot 52 that is adapted to the humidification pipe 3, and the humidification pipe 3 is movably connected to it. The mesh plate 53 is fixedly connected to the lower part of the inner wall of the frame 51. The top surface of the middle part of the frame 51 is provided with a number of fixing slots 511, and a fixing rod 333 is movably connected to them. The fixing slots 511 and the fixing rods 333 cooperate to facilitate the removal and fixing of the fermentation box 5.

[0036] Working principle: During use, open the door 11, place the Pu-erh tea to be fermented into the fermentation box 5, and then close the door 11. The temperature and humidity transmitter 4 will transmit the temperature and humidity information inside the chamber 1 to the control panel 12 via a line. The control panel 12 will display the temperature and humidity inside the chamber 1. When it is necessary to adjust the temperature and humidity inside the chamber 1, the heating element inside the chamber 1 can be controlled via the buttons on the control panel 12 to adjust the temperature. The motor 2 can be turned on, which will drive the connected rotating shaft 21 to rotate. The rotating shaft 21 will then drive the humidification tube 3 to rotate. The fermentation box 5, which is fixed to the humidification tube 3 by the limiting component 33 and the limiting ring 34, will be rotated, thereby making the Pu'er tea in the fermentation box 5 heat more evenly. At the same time, the humidifier can be turned on, which will humidify the box 1 through the first connecting pipe 6 connected to it, or the dehumidifier can be turned on, which will dehumidify the box 1 through the second connecting pipe 7 connected to it. When the humidifier is turned on, the gas containing water vapor will be transported to the humidification tube 3 through the first connecting pipe 6, and then sent to the fermentation box 5 through the humidification port 31 on the humidification tube 3, so that the Pu'er tea in the fermentation box 5 can be humidified more evenly.

[0037] When the Pu-erh tea fermentation is complete and it needs to be removed, the adjusting ring 331 can be rotated to move it upwards along the spiral pattern 32 on the humidifying tube 3, thereby moving the positioning ring 332 connected to it upwards as well, so that the fixing rod 333 disengages from the fixing groove 511. Then the fermentation box 5 can be removed from the humidifying tube 3, and the Pu-erh tea in the fermentation box 5 can be poured out for collection. After the Pu-erh tea in the fermentation box 5 has been collected, the slot 52 at the rear of the fermentation box 5 can be locked onto the humidifying tube 3, so that the bottom surface of the middle part of the frame 51 rests on the limiting ring 34. Then the adjusting ring 331 can be rotated in the opposite direction to move the positioning ring 332 downwards, so that the multiple fixing rods 333 can be inserted into the fixing groove 511.

[0038] 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.
