Description

Technical Field

[0001] This invention relates to the field of tea processing technology, and more specifically to a tea processing fermentation device. Background Technology

[0002] Fermentation is a crucial step in tea processing that significantly impacts tea quality, requiring strict control of temperature, humidity, ventilation, and material uniformity. Existing tea fermentation equipment suffers from several shortcomings: First, materials are often statically piled up, leading to uneven fermentation and dead zones, resulting in inconsistent tea quality. Second, humidification is typically achieved through internal spraying, which fails to evenly penetrate the material, especially with thicker piles, resulting in an overly wet outer layer and a dry inner layer. Third, temperature control relies heavily on wall heating, leading to uneven heat distribution, with areas closer to the heat source being warmer and areas further away being colder. Fourth, material handling is inconvenient, particularly with large fermentation equipment, as loading and unloading are time-consuming, labor-intensive, and prone to damaging the materials. Fifth, the complex internal structure makes cleaning and maintenance difficult, easily leaving impurities that can affect the quality of subsequent fermentation batches.

[0003] Furthermore, although some equipment is equipped with a stirring mechanism, the stirring process can easily cause mechanical damage to the tea leaves, destroying their shape. At the same time, traditional stirring methods struggle to achieve uniform material distribution, resulting in localized accumulation problems. Therefore, there is an urgent need for tea processing and fermentation equipment that can achieve uniform material distribution, precise and uniform temperature and humidity control, and convenient loading and unloading, to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a tea processing and fermentation equipment that can achieve uniform material distribution, precise and uniform temperature and humidity control, and convenient loading and unloading.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A tea processing fermentation device includes a fermentation chamber and a top cover fixedly installed on the top of the fermentation chamber. The fermentation chamber has doors on both sides and a heating mechanism at the bottom of the fermentation chamber. A drive assembly is fixedly installed above the top cover, and a ventilation mechanism is also installed above the top cover. A humidity regulating mechanism is fixedly connected to one side of the fermentation chamber, and a water bucket is fixedly connected to one end of the humidity regulating mechanism.

[0007] Preferably, the fermentation chamber includes a hollow rotating shaft fixedly disposed in the center of the internal cavity of the fermentation chamber and an annular material basket fixedly connected to both sides of the hollow rotating shaft.

[0008] Preferably, the top of the hollow shaft extends and is nested to connect to the first pipe, and the top of the hollow shaft is connected to the drive assembly.

[0009] Preferably, the hollow shaft has a plurality of air vents evenly distributed on its surface, that is, the hollow shaft integrates a moisture channel inside.

[0010] Preferably, the annular material basket includes an annular dividing net, and a limiting strip is provided at one right end of the annular material basket. At the same time, a limiting groove that cooperates with the limiting strip is fixedly set on the hollow rotating shaft.

[0011] Preferably, the drive assembly includes a drive motor and a first gear nested on the motor output shaft, and a second gear meshing with the first gear, the second gear being fixedly connected to a hollow rotating shaft.

[0012] The tea processing and fermentation equipment provided by this invention has the following advantages compared with the prior art:

[0013] Uniform material distribution, avoiding dead zones: By setting up a rotating annular material basket driven by a drive component, the centrifugal force of rotation ensures that the tea leaves are evenly distributed across each layer of the annular separating mesh, completely solving the problem of uneven fermentation caused by traditional static stacking. The structural design of the annular separating mesh, combined with the rotational motion, ensures that each tea leaf has full contact with the fermentation environment, significantly improving the consistency of tea quality.

[0014] Uniform moisture penetration and excellent humidification effect: The innovative design of hollow rotating shaft integrated moisture channel allows moisture to directly enter the interior of the annular material basket through the uniform air pores on the surface of the hollow rotating shaft. Combined with the rotation of the material, the moisture permeates from the center of the material to the outside. Compared with the traditional external spraying method, the moisture distribution is more uniform, effectively avoiding the drawbacks of excessive moisture on the outside and dryness on the inside, thus improving humidification efficiency and accuracy.

[0015] More precise temperature control and more even heat distribution: The bottom heating mechanism, combined with the rotating material movement, allows heat to be fully transferred in the inner cavity of the chamber through convection and material rotation. This avoids local temperature deviations caused by traditional wall heating, ensuring that the temperature in all areas of the chamber is consistent and providing a stable temperature environment for tea fermentation.

[0016] Easy to operate and efficient for loading and unloading materials: The doors on both sides of the fermentation chamber correspond to the circular material basket area. With the limiting strip and limiting groove structure between the circular material basket and the hollow rotating shaft, users can quickly install and disassemble the material basket by moving it up and down. This greatly simplifies the process of picking up and putting down tea leaves, reduces material damage, and improves production efficiency, making it especially suitable for large-scale production.

[0017] The overall fermentation environment is stable and controllable: The equipment integrates drive components, heating mechanisms, ventilation mechanisms, and humidity control mechanisms. These systems work together to precisely control temperature, humidity, and ventilation conditions during fermentation. Combined with the uniform distribution and rotational movement of the materials, this provides a stable and consistent environment for tea fermentation, significantly improving the quality and production efficiency of the fermented tea.

[0021] Figure 4 This is a schematic diagram of the structure of the annular material basket of the present invention; Detailed Implementation

[0022] like Figures 1-4 As shown: The present invention provides a tea processing fermentation device, including a fermentation box 1 and a top cover 2 fixedly installed on the top of the fermentation box 1. The fermentation box 1 has doors 3 on both sides, a heating mechanism 4 at the bottom of the fermentation box 1, a drive assembly 5 fixedly installed on the top cover 2, and a ventilation mechanism 6 also installed on the top cover 2. A humidity regulating mechanism 9 is fixedly connected to one side of the fermentation box 1, and one end of the humidity regulating mechanism 9 is fixedly connected to a water tank 11.

[0023] The fermentation chamber 1 includes a hollow rotating shaft 8 fixedly installed in the center of the inner cavity of the fermentation chamber 1 and annular material baskets 12 fixedly connected to both sides of the hollow rotating shaft 8. The top of the hollow rotating shaft 8 extends and is nested to connect to a first pipe 7. At the same time, the top of the hollow rotating shaft 8 is connected to a drive assembly 5. When the drive assembly 5 is working, it causes the hollow rotating shaft 8 and the annular material baskets 12 to rotate at a uniform speed. Furthermore, a number of ventilation holes are evenly arranged on the surface of the hollow rotating shaft 8, that is, the hollow rotating shaft 41 integrates a moisture channel inside, and the tea leaves in the annular material baskets 12 are humidified through the ventilation holes.

[0024] The fermentation chamber 1 has a sealed inner cavity for holding tea leaves to be fermented. The fermentation chamber 1 has doors 3 on both sides, and the doors 3 correspond to the annular material basket 12 area inside the fermentation chamber 1. Tea leaves can be taken out and put in by opening the doors.

[0025] Furthermore, the aforementioned annular material basket 12 includes an annular dividing mesh 121. Fermented tea leaves can be filled into the annular dividing mesh 121 through its top opening. Under the action of centrifugal force, the material is evenly distributed among the mesh layers, avoiding accumulation dead zones. A limiting strip 122 is provided at one end of the right side of the annular material basket. Simultaneously, a limiting groove 123, which cooperates with the limiting strip 122, is fixedly installed on the hollow rotating shaft 8. The annular material basket 12 can be detached from and installed on the hollow rotating shaft 8 by the user moving it upwards and downwards.

[0026] The drive assembly 5, fixedly installed on the top of the fermentation chamber 1, includes a drive motor 501, a first gear 502 nested on the output shaft of the motor 501, and a second gear 503 meshing with the first gear 502. The second gear 503 is fixedly connected to a hollow rotating shaft 8. The first motor is a DC motor. The first gear 502 and the second gear 503 are identical gears that mesh with each other. The drive motor 501 causes the first gear 502 to rotate, thereby driving the second gear 503 to rotate, which in turn causes the hollow rotating shaft 8 and the annular material basket 12 to rotate. This allows moisture to be released into the tea leaves in a 360° rotation, improving the uniformity of heating of the tea material.

[0027] The temperature regulation system includes a heating mechanism 4 disposed at the bottom of the fermentation chamber 1. The heating mechanism 4 is electrically connected to a temperature sensor 13 disposed at the top of the inner cavity of the fermentation chamber 1. The temperature sensor 13 is used to control the working state of the heating mechanism 4 according to a preset temperature range to regulate the temperature inside the inner cavity.

[0028] The humidity control system includes a humidity control mechanism 9 fixedly connected to one side of the fermentation chamber 1. The humidity control mechanism 9 is an atomizing humidifier. One end of the humidity control mechanism 9 is connected to an external water tank 11 through a second pipe 10. The humidity control mechanism 9 is electrically connected to a humidity sensor 14 located at the top of the inner cavity of the fermentation chamber 1. The humidity sensor 14 is used to control the working state of the humidity control mechanism 9 according to a preset temperature range, thereby adjusting the amount of spray that the humidity control mechanism 9 sprays into the inner cavity to regulate the humidity inside the inner cavity.

[0029] The ventilation mechanism 6 is fixedly installed above the top cover 2. The ventilation mechanism 6 is an exhaust fan. The exhaust fan is electrically connected to an external control system. The control system is used to control the operation of the exhaust fan to realize the circulation and renewal of air in the inner cavity.

[0030] This invention provides a tea processing and fermentation equipment that, compared to existing technologies, has the following advantages:

[0031] Uniform material distribution, avoiding dead zones: By setting up a rotating annular material basket driven by a drive component, the centrifugal force of rotation ensures that the tea leaves are evenly distributed across each layer of the annular separating mesh, completely solving the problem of uneven fermentation caused by traditional static stacking. The structural design of the annular separating mesh, combined with the rotational motion, ensures that each tea leaf has full contact with the fermentation environment, significantly improving the consistency of tea quality.

[0032] Uniform moisture penetration and excellent humidification effect: The innovative design of hollow rotating shaft integrated moisture channel allows moisture to directly enter the interior of the annular material basket through the uniform air pores on the surface of the hollow rotating shaft. Combined with the rotation of the material, the moisture permeates from the center of the material to the outside. Compared with the traditional external spraying method, the moisture distribution is more uniform, effectively avoiding the drawbacks of excessive moisture on the outside and dryness on the inside, thus improving humidification efficiency and accuracy.

[0033] More precise temperature control and more even heat distribution: The bottom heating mechanism, combined with the rotating material movement, allows heat to be fully transferred in the inner cavity of the chamber through convection and material rotation. This avoids local temperature deviations caused by traditional wall heating, ensuring that the temperature in all areas of the chamber is consistent and providing a stable temperature environment for tea fermentation.

[0034] Easy to operate and efficient for loading and unloading materials: The doors on both sides of the fermentation chamber correspond to the circular material basket area. With the limiting strip and limiting groove structure between the circular material basket and the hollow rotating shaft, users can quickly install and disassemble the material basket by moving it up and down. This greatly simplifies the process of picking up and putting down tea leaves, reduces material damage, and improves production efficiency, making it especially suitable for large-scale production.

[0035] The overall fermentation environment is stable and controllable: The equipment integrates drive components, heating mechanism, ventilation mechanism, humidity regulation mechanism, etc. The various systems work together to accurately control the temperature, humidity and ventilation conditions during the fermentation process. Combined with the uniform distribution and rotation of materials, it provides a stable and consistent environment for tea fermentation, which significantly improves the quality and production efficiency of fermented tea.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
