Description

Technical Field

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

[0002] Tea fermentation is a crucial step in tea processing that determines tea quality. It involves controlling the oxidation-reduction reaction of tea leaves under specific temperature, humidity, and oxygen conditions to create the tea's unique color, aroma, and flavor. To achieve precise control of this process, the tea processing industry has gradually adopted automated fermentation equipment. This typically utilizes temperature and humidity chambers combined with mechanical turning or spraying structures to simulate fermentation conditions under natural conditions, thereby improving production efficiency and ensuring the stability of tea quality.

[0003] However, existing tea fermentation devices, exemplified by patent CN121264545A, still have significant drawbacks in practical applications: First, hygiene and maintenance are difficult. The device contains numerous precision transmission components (such as external gear rings, sliding sleeves, cams, and spring telescopic rods). Tea processing debris easily falls into gear meshing points or gaps, causing jamming and wear. Furthermore, due to its non-modular waterproof design, it cannot be directly rinsed with water, making disassembly and cleaning extremely time-consuming. Additionally, the humidification pipeline, when exposed to a humid environment for extended periods, is prone to mold growth and is difficult to disinfect. Second, structural reliability and stability are questionable. Its vibration mode employs a "lifting and then suddenly dropping" gravity impact, which significantly affects the fatigue life of components. Moreover, the synchronicity of lifting and lowering relies on the sliding fit between the convex rod and the track groove, making it prone to jamming when the force is uneven, leading to damage to the base. The existing equipment suffers from several shortcomings. First, it cannot move in and out normally. Second, its automation and ease of operation are insufficient. Although the base can be moved out electrically, the placement of the tray still requires manual alignment, and the water tank needs to be manually replenished. Furthermore, it lacks precise control devices for core fermentation parameters such as temperature and oxygen content, making it difficult to guarantee fermentation quality. Third, its sealing is obviously flawed. The sliding connection between the base and the main body of the equipment inevitably creates gaps, allowing high-temperature and high-humidity steam to easily leak into electrical components such as the electric push rod or motor, causing corrosion or short circuits. Finally, the risk of tea leaf damage is high. Relying on rigid spraying parts to block the rotating tea leaves for stirring and drop vibration results in excessive mechanical impact on delicate buds and leaves, easily leading to increased tea breakage and affecting the quality of the finished product. Therefore, a tea fermentation device for tea processing is needed to address these shortcomings. Summary of the Invention

[0004] Technical problems to be solved Existing tea fermentation equipment is often too complex in structure and lacks effective protection for the tea leaves, making equipment maintenance difficult and easily damaging the tea leaves during the turning process.

[0005] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a tea fermentation device for tea processing, comprising: The fermentation cabinet has an integrated touch screen on top for human-machine interaction and parameter setting.

The top surface of the wedge is constructed as a guide slope so that the wedge can be inserted into the limiting groove under the action of the restoring force. The longitudinal depth of the limiting groove is configured to be greater than the longitudinal height of the wedge, thereby providing clearance space for the longitudinal micro-vibration of the fermentation box during operation.

[0007] Furthermore, a pair of flexible vibrators are fixedly connected to the bottom of each tray, with their telescopic ends abutting against the bottom of the fermentation box. The control components include: A collar is rotatably connected to the internal mounting hole of the tray; A control bolt is threaded onto the front sidewall of the support plate.

[0010] Furthermore, the water supply system includes: The main pipe is longitudinally fixed to the inner wall of the fermentation tank; Several secondary pipes are branched and connected to the main pipe, and are respectively fixedly connected to the top of the corresponding support rod. The end of each secondary pipe away from the main pipe is rotatably connected to the top of the spiral pipe, forming a rotary sealing water supply structure. A water tank is fixedly connected to the bottom of the outside of the fermentation cabinet. The inlet end of the main pipe extends into the water tank and is connected to the outlet end of the water pump inside the water tank.

[0011] Furthermore, the rotating assembly includes: Several synchronizing components are respectively built into the internal space of the corresponding support rod, and their power output ends are connected to the outer wall of the spiral tube; A rotary rod, rotatably connected through the interior of the fermentation tank, is used to synchronously control the operation of several of the synchronizing components; A servo motor is fixedly mounted on the top support of the fermentation tank, and its output shaft is connected to the top of the rotary rod to provide rotational power. The synchronization element includes: Synchronous pulley one is fixedly fitted onto the outer wall of the spiral tube; Synchronous pulley two is fixedly mounted on the rotating rod; A synchronous belt is wrapped around the first synchronous pulley and the second synchronous pulley to form a belt drive structure to achieve synchronous power transmission.

[0012] Furthermore, it also includes a loop component, the loop component comprising: A dehumidification fan is fixedly installed at the top ventilation opening of the fermentation cabinet; A drainage pipe is fixedly connected to the back side wall of the fermentation cabinet. The air inlet of the drainage pipe is opposite to the air outlet of the dehumidification fan, and the air outlet of the drainage pipe extends downward into the interior of the water tank. A filter is fixedly installed on the back side wall of the fermentation tank, and the drainage pipe passes through the filter element area of ​​the filter to filter the discharged hot and humid gas.

[0013] Furthermore, the environmental control system includes: A temperature and humidity control module is installed in the inner wall and interlayer of the fermentation cabinet to precisely regulate the temperature and relative humidity of the air environment inside the fermentation cabinet. And a multi-dimensional sensor array, set at monitoring points inside the fermentation tank, for real-time collection and feedback of temperature and humidity data inside the fermentation tank; The temperature and humidity control module is configured to automatically compensate and adjust the fermentation environment based on the real-time data fluctuations collected by the multi-dimensional sensor array, so as to maintain the constant environment required for the fermentation process.

[0014] Furthermore, it also includes a movable component, located at the bottom of the fermentation tank, for driving the support frame to move out or into the fermentation tank as a whole; The moving component includes: A pair of slide rails are fixedly connected to the bottom plate of the fermentation tank in a horizontal direction; A pair of sliders are slidably connected to the slide rail, and the top of the slider is fixedly connected to the bottom of the bottommost support plate. An electric push rod is fixedly installed at the bottom of the fermentation tank, and the end of its telescopic rod is fixedly connected to the bottom of the bottommost tray to provide pushing and pulling power; A corrugated pipe is fitted onto the outside of the telescopic rod of the electric push rod. One end of the corrugated pipe is fixedly connected to the housing of the electric push rod, and the other end is fixedly connected to the bottom of the support plate, for dustproof sealing of the telescopic rod.

[0015] Compared with existing technologies, this tea fermentation device for tea processing has the following advantages: I. This invention drives the rotating tube and the receiving tube in the spraying component to rotate synchronously through the rotating component, which drives the soft strip at the bottom of the receiving tube to gently stir and tumble the tea leaves. This not only prevents the tea leaves from hardening on the surface, but also allows the water mist to penetrate the tea leaf layer more evenly in conjunction with the rotating spray of the nozzle, avoiding local over-wetting or dryness and improving the precision of humidification.

[0016] Second, by setting up a circulation component including a dehumidifying fan, a filter, and a drainage pipe, the present invention can extract the supersaturated hot and humid air in the fermentation cabinet and discharge it into the water tank after filtering out impurities. This achieves dynamic balance of humidity in the cabinet and condenses and recovers water vapor through heat exchange. At the same time, it is combined with fresh air supply through a one-way air inlet to build an energy-saving, environmentally friendly and clean air circulation system. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-9 As shown, the present invention provides a technical solution: a tea fermentation device for tea processing, which integrates an environmental control and mechanical motion system for automatically fermenting, humidifying, and turning the tea leaves placed inside. The core advantage of this device lies in the integration of a modular fermentation box 5, a movable support frame, and precise temperature and humidity control, thereby meeting the stringent requirements of different types of tea for the fermentation environment and improving the convenience of cleaning and maintenance. The fermentation device mainly includes a fermentation cabinet 1, a support frame, a fermentation box 5, a limiting component 6, a spraying component 7, a rotating component 8, an environmental control system, a circulation component, and a moving component.

[0021] Fermentation cabinet 1, serving as the external support structure of the entire device, has an integrated touchscreen display 2 on its top. Operators can interact with the system through this display to set various parameters required for the fermentation process, such as fermentation temperature, target humidity, spraying cycle, and vibration frequency. Furthermore, to improve gas exchange during fermentation and promote aerobic respiration of the tea leaves, one-way air inlets are located on both sides of the bottom of fermentation cabinet 1. Fresh air from outside can be naturally drawn in or forced into the cabinet through these inlets, effectively preventing backflow of tea dust. A slidable support frame is installed inside fermentation cabinet 1. The core component supporting the fermentation unit mainly includes several trays 3 arranged in a longitudinal array and a pair of L-shaped connecting plates 4. The L-shaped connecting plates 4 pass through and are fixedly connected to the ends of the trays 3, forming a stable shelf-like frame. Fermentation boxes 5 for holding tea leaves to be fermented are inserted between the inner side walls of each tray 3. To facilitate handling and handling, a pair of handles are fixedly connected to the opposite outer side walls of each fermentation box 5. In addition, a moving component is provided at the bottom of the fermentation cabinet 1 to drive the support frame to move out or into the fermentation cabinet 1 as a whole, which greatly facilitates the loading and unloading operations.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the limiting component 6 is a key structure correspondingly set in the internal cavity of each tray 3, used to securely restrain the fermentation box 5 on the tray 3 and prevent accidental slippage during movement or operation. The limiting component 6 mainly includes a pair of limiting members symmetrically arranged on both sides inside the tray 3 and a control component installed on the front end face of the tray 3. Specifically, the limiting member consists of a wedge 601 slidably embedded in the internal groove of the tray 3, a traction rope 602 arranged in the internal channel of the tray 3, and a return spring 603 sleeved on the outside of the traction rope 602. One end of the traction rope 602 is fixedly connected to the back side wall of the wedge 601, and one end of the return spring 603 is connected to the back side of the wedge 601, and the other end is connected to the inner wall of the tray 3. A pair of limiting grooves 9 are correspondingly opened on the outer side wall of the fermentation box 5. The top surface of the wedge 601 is constructed as a guide slope. In the natural state, the elastic force of the return spring 603 pushes the wedge. Block 601 is inserted into the limiting groove 9 to lock the fermentation box 5. At the same time, the longitudinal depth of the limiting groove 9 is designed to be greater than the longitudinal height of the wedge 601. This design is crucial because it allows the wedge 601 to move up and down within the limiting groove 9 when the fermentation box 5 is excited by the vibrator below. This ensures the effectiveness of the locking and provides necessary clearance for the longitudinal micro-vibrations of the fermentation box 5 during operation. To achieve quick unlocking, the control components include a collar 604 rotatably connected in the mounting hole inside the tray 3 and a control bolt 605 threaded onto the front side wall of the tray 3. The front section of the control bolt 605 has a polygonal cross-section and moves in conjunction with the inner hole of the collar 604. The operator only needs to rotate the control bolt 605 to drive the collar 604 to rotate, thereby pulling the wedge 601 through the traction rope 602 to overcome the reset force and separate from the limiting groove 9, thus releasing the restriction on the fermentation box 5.

[0023] To promote uniform tea fermentation, a pair of flexible vibrators 10 are fixedly connected to the bottom of each tray 3. The telescopic ends of the flexible vibrators 10 extend upward and abut against the bottom of the fermentation box 5 placed on the tray 3. During the fermentation process, the flexible vibrators 10 generate high-frequency micro-amplitude vibrations and transmit them to the fermentation box 5, so that the tea leaves piled inside can be loosened and breathable, avoiding uneven fermentation or the generation of "piling" odor due to the compaction of tea leaves. At the same time, the avoidance design of the limiting component 6 ensures the stability and safety of the vibration process.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the spraying assembly 7 is installed inside the fermentation cabinet 1 and is mainly used to evenly spray and humidify the tea leaves in each fermentation box 5. This is a key step in controlling humidity during the tea fermentation process. The spraying assembly 7 mainly includes several longitudinally fixed support rods 701 connected to the inner wall of the fermentation cabinet 1. Each support rod 701 has a spraying component rotatably connected to its end, which is suspended above the tray 3. The specific structure of the spraying component includes a spiral tube 702 rotatably connected to the end of the support rod 701, and a receiving tube is fixedly connected to the bottom end of the spiral tube 702. 703, the bottom surface of the receiving tube 703 is fixed with multiple nozzles 704, the spraying area of ​​the nozzles 704 covers the support plate 3 located below them. In addition, several flexible strips 705 are fixed in an array on the bottom surface of the receiving tube 703. These flexible strips 705 are distributed alternately with the nozzles 704. When the spraying device is working, the flexible strips 705 rotate to gently move and stir the tea leaves below, which can prevent the surface of the tea leaves from hardening and hindering water absorption, and can also work with the nozzles 704 to make the water mist penetrate into the interior of the tea leaf layer more evenly.

[0025] The water source for the spraying assembly 7 is provided by a water tank 708 installed on the main body of the fermentation tank 1. The water tank 708 is fixedly connected to the bottom of the outside of the fermentation tank 1. In order to achieve long-term automated operation, the inlet end of the water tank 708 is designed to be connected to an external water pipe, thereby realizing automatic water addition and eliminating the tediousness of frequent manual water addition. The inlet end of the main pipe 706 extends into the water tank 708 and is connected to the outlet end of the water pump inside the water tank 708. Several secondary pipes 707 are branched on the main pipe 706. The secondary pipes 707 are fixedly connected to the top of the corresponding support rod 701, and the end of the secondary pipe 707 away from the main pipe 706 is rotatably connected to the top of the rotary pipe 702 to form a rotary sealed water supply structure. The water is delivered to each nozzle 704 for atomized spraying by the water pump.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the rotating component 8 is the power core driving the spraying component's movement. It is located inside the fermentation tank 1 and is used to drive the spraying component 7 to perform rotational motion, thereby expanding the spraying range and causing the flexible agitator 705 to agitate the tea leaves. The rotating component 8 includes a servo motor 802 fixedly mounted on the top support of the fermentation tank 1. Its output shaft is driven by a rotating rod 801 that is rotatably connected through the inside of the fermentation tank 1. A synchronizing element is built into the internal space of each supporting rod 701. The power output end of the synchronizing element is connected to the outside of the rotating tube 702. The wall-to-wall connection specifically includes a synchronization wheel 803 fixedly mounted on the outer wall of the rotary tube 702, a synchronization wheel 804 fixedly mounted on the rotary rod 801, and a synchronization belt 805 wrapped around the synchronization wheel 803 and the synchronization wheel 804. When the servo motor 802 starts, it drives the rotary rod 801 to rotate, and then drives all the rotary tubes 702 to rotate synchronously through the synchronization belt 805 and the synchronization wheel in each synchronization component, so as to realize the synchronous transmission of power and ensure that the multi-layer fermentation box 5 sprays and turns at the same time and at the same speed.

[0027] To maintain the cleanliness and humidity balance of the internal environment of the fermentation cabinet 1, the device also includes a circulation component. The circulation component includes a dehumidifying fan 11 fixedly installed at the ventilation opening at the top of the fermentation cabinet 1. A drainage pipe 12 is fixedly connected to the back side wall of the fermentation cabinet 1. The air inlet of the drainage pipe 12 is opposite to the air outlet of the dehumidifying fan 11, while the air outlet extends downward to the interior of the water tank 708. A filter 13 is also installed on the back side wall of the fermentation cabinet 1 through which the drainage pipe 12 passes. The drainage pipe 12 passes through the filter element area of ​​the filter 13. During operation, the dehumidifying fan 11 extracts the supersaturated hot and humid air from the fermentation cabinet 1. After the filter 13 filters out tea leaves and dust, the air is discharged into the water tank 708 through the drainage pipe 12. The hot and humid air can be recycled as a water source after condensation in the water tank 708. The filter 13 effectively prevents impurities from entering the water tank 708 and causing blockage, thus achieving a combination of energy saving and environmental protection.

[0028] To precisely control the fermentation environment, fermentation cabinet 1 is equipped with an environmental control system. This system includes a temperature and humidity regulation module (not shown in the prior art diagram) and a multi-dimensional sensor array. The temperature and humidity regulation module is located in the inner wall and interlayer of fermentation cabinet 1 and contains heating, cooling, and humidification elements. It is used to precisely regulate the air temperature and relative humidity inside the cabinet to simulate the optimal fermentation environment for different types of tea (such as black tea, which requires high temperature and high humidity, and green tea, which requires relatively low temperature). The multi-dimensional sensor array is set at multiple monitoring points inside fermentation cabinet 1 to collect and feed back temperature and humidity data in real time. The temperature and humidity regulation module is electrically connected to the multi-dimensional sensor array and automatically compensates for fluctuations in the real-time data collected by the sensors. For example, it automatically heats when the temperature is lower than the set value and starts humidifying when the humidity is too low, thereby maintaining the constant environment required for the fermentation process and ensuring the stability of tea quality.

[0029] Finally, the moving component is a key auxiliary mechanism for convenient material loading. It is located at the bottom of the fermentation cabinet 1. The moving component includes a pair of slide rails 14 fixedly connected to the bottom plate of the fermentation cabinet 1 in the horizontal direction, and a pair of slide bars 15 respectively slidably connected to the slide rails 14. The top of the slide bar 15 is fixedly connected to the bottom of the bottom tray 3, thereby driving the entire support frame to move. The electric push rod 16 is fixedly installed at the bottom of the fermentation cabinet 1. The end of its telescopic rod is fixedly connected to the bottom of the bottom tray 3, providing push and pull power for the support frame to move out or in. In order to protect the electric push rod 16 from the corrosion of tea dust and moisture inside the fermentation cabinet 1, a corrugated pipe 17 is fitted on the outside of the telescopic rod of the electric push rod 16. One end of the corrugated pipe 17 is fixedly connected to the housing of the electric push rod 16, and the other end is fixedly connected to the bottom of the tray 3, which plays an effective role in dust prevention and sealing.

[0030] Working process: First, according to the type of tea to be processed and the processing requirements, the temperature and humidity parameters are set in the environmental control system through the touch screen 2. Then, the electric push rod 16 of the moving component pulls the support frame out of the fermentation cabinet 1. The operator places the fermentation box 5 filled with tea onto the tray 3 through the handle, and the limit component 6 automatically locks it. Subsequently, the support frame is pushed back into the cabinet and locked. The environmental control system is started, and the multi-dimensional sensor array monitors and adjusts the environment inside the cabinet to the fermentation state. During the fermentation process, the servo motor 802 drives the spray component to rotate through the rotating component 8, the soft agitator 705 moves the tea leaves, and the nozzle 704 intermittently replenishes water. The flexible vibrator 10 at the bottom of the tray 3 works synchronously to help loosen the tea leaves. When the humidity inside the cabinet is too high, the circulation component is started, and the dehumidification fan 11 extracts the hot and humid air for filtration, condensation, and recovery. After the fermentation is completed, the support frame is removed again to take out the tea leaves. The whole process is highly automated, easy to clean and maintain, and greatly ensures the quality of tea fermentation.
