Description

Technical Field

[0001] This invention relates to the technical field of tea processing equipment, particularly the field of black tea processing, and especially to a precision fermentation equipment for wild black tea. Background Technology

[0002] Wild black tea, due to its natural growing environment and rich internal substances, has extremely high requirements for temperature, humidity, oxygen content, and uniform turning during the fermentation process. Traditional fermentation equipment mostly uses static stacking or simple turning methods, which makes it difficult to achieve precise control of the fermentation environment, easily leading to uneven fermentation and unstable quality. At the same time, existing equipment has shortcomings in tea feeding and discharging, layered fermentation, automatic turning, and drying, and cannot meet the high-quality and high-efficiency fermentation requirements of wild black tea.

[0003] Chinese invention patent CN 113273620 A discloses an intelligent production equipment for fermenting Lao Ying black tea. This equipment includes a fermentation tank, a stirring shaft, a control box, and drainage pipes. A feeding port is located on the upper left side surface of the fermentation tank. A bearing groove runs through the upper surface of the fermentation tank, housing a sealed bearing. A stirring motor is mounted on the upper surface of the fermentation tank, and the stirring shaft is located inside the fermentation tank. The control box is located on the upper right side surface of the fermentation tank. Multiple drainage pipes of various sizes are provided, each with a tea filter screen on its inner surface. A discharge port is located in the middle of the lower surface of the fermentation tank, with a protective cover on its lower surface. Multiple support legs are located along the edge of the lower surface of the fermentation tank. This fermentation equipment uses a stirring method to agitate and ferment the tea leaves. This method causes significant compression and breakage of the tea leaves, affecting the taste and appearance, making it impossible to produce high-quality black tea, and also resulting in low fermentation efficiency. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art by providing a precise fermentation equipment for wild black tea that can achieve precise control of the fermentation environment, automatic turning and uniform fermentation of tea leaves, convenient feeding and discharging, and drying function. This equipment meets the requirements of precise control of the fermentation environment, high efficiency of black tea fermentation, and high quality of fermented black tea.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: This wild black tea precision fermentation equipment includes a shell, and a tea holding and fermentation mechanism is set inside the shell; the tea holding and fermentation mechanism includes a support plate, a bracket is fixed on the support plate, and sprocket sets are set on the inner and outer sides of the bracket. Each sprocket set includes sprockets rotatably connected to the top and bottom of the bracket. A chain is installed between the inner and outer sprockets. A set of longitudinally spaced holding components is set on the left and right sides of the two chains. A drive motor for driving the sprocket sets to rotate is installed on the bracket; each holding component includes a first grid holding plate hinged to the inner and outer chains, a second grid holding plate is set above the first grid holding plate, and downwardly set components are fixed on the left, right and inner outer contours of the second grid holding plate. The enclosure has cylindrical support rods fixed at the four corners of the first grid holding plate, and threaded posts are fitted onto each cylindrical support rod. Each threaded post is threaded together with the second grid holding plate. A miniature torque motor is fixed at the top of each cylindrical support rod. The miniature torque motor is a hollow motor, and the shaft of each miniature torque motor is coaxially fixed to the top of each threaded post. Track grooves are opened on the support plate, and the track grooves are consistent with the rotation trajectory of the sprocket. A cylindrical block that mates with the track groove is fixed to the side end of each first grid holding plate. Humidity sensor, temperature sensor and oxygen sensor are installed inside the shell. Humidification pipe, heating pipe and oxygenation pipe are installed on the back of the shell. Airflow circulation fan is installed at the bottom of the shell. Exhaust fan communicating with the shell cavity is fixed at the top of the shell.The function of this tea fermentation mechanism is to hold and continuously agitate the tea leaves, ensuring they receive even humidity, temperature, and oxygen, thus guaranteeing the quality of the fermented black tea. The humidity sensor, temperature sensor, oxygen sensor, humidifier, heater, oxygenator, airflow fan, and exhaust fan monitor the fermentation environment in real time and control humidification, heating, oxygenation, and ventilation for precise fermentation. Since waste gas is generated during tea fermentation, the exhaust fan is necessary to promptly remove it, ensuring high-quality fermentation. The working principle of this tea fermentation mechanism is as follows: first, the raw tea leaves (after withering and rolling) are... The clamps are inserted into the first grid holding plates for raw material fermentation. These first grid holding plates not only hold the tea leaves but also provide good vertical airflow, accelerating fermentation and improving quality. However, the tea leaves pressed to the bottom of the first grid holding plates still suffer from poor airflow and temperature control, making fermentation quality difficult to manage. Therefore, the four corner miniature torque motors are activated, driving the threaded columns to rotate. Because the threaded columns engage with the second grid holding plates, the second grid holding plates move closer to the first grid holding plates, compressing the tea leaves. The purpose is to use the chain rotation to move the holding pieces on the left to the right, and vice versa. Rotating to the left, the second grid plate is positioned below and the first grid plate above, turning the bottom layer of tea leaves into the top layer. This allows for precise control of the fermentation of each tea leaf. The first and second grid plates clamp the tea leaves together to prevent them from falling due to gravity when passing through the curved areas at the top and bottom of the chain. After the tea leaves have turned, the miniature torque motors at the four corners are activated again, driving the threaded columns to rotate in the opposite direction. This causes the first and second grid plates to move away from each other, ensuring that the tea leaves, after turning, are precisely fermented on the second grid plate. This results in high-quality fermentation of each tea leaf. The chain is rotated multiple times by the drive motors. Turning the tea leaves over multiple times greatly improves the fermentation quality of each type. The airflow circulation fan ensures the circulation of air within the casing, guaranteeing more uniform humidity, temperature, and oxygen levels, ensuring that each area of ​​the tea receives constant humidity, temperature, and oxygen for fermentation. The baffle plate serves to limit the amount of tea leaves during turning, preventing a small amount from falling off when the container is rotating vertically. It also prevents the dried black tea from leaking out from the side of the second grid container when it is being discharged at an angle. The humidity sensor, temperature sensor, oxygen sensor, and miniature torque motor are all commercially available products.

[0006] Further improvements include outlets on the left and right sides of the casing, hinged opening and closing doors on both sides, and first electric cylinders on the top left and right sides of the casing. A first vertical block is fixed to the top of each opening and closing door, and a pair of opposing second vertical blocks are fixed to the casing. The tail ends of the two first electric cylinders are ball-jointed to the two second vertical blocks, and the piston heads of the two first electric cylinders are ball-jointed to the two first vertical blocks. The left and right outlets, opening and closing doors, and first electric cylinders facilitate the insertion and removal of tea leaves into the fermentation mechanism, allowing for the addition of tea leaves and the discharge of fermented black tea.

[0007] Further improvements include the installation of a pair of tea-containing fermentation mechanisms within the casing. These two mechanisms are slidably connected to the casing along the opening and closing direction of the door. A pair of second electric cylinders, each driving a support plate, are fixed to the casing. The purpose of this pair of tea-containing fermentation mechanisms is not only to increase the quantity and efficiency of black tea fermentation, but also to improve the stability of the casing by extending it to the left and right sides via the second electric cylinders. This prevents the casing from tipping over due to the single tea-containing fermentation mechanism extending unidirectionally.

[0008] Further improvements include the addition of a self-lubricating layer made of tin bronze on the contour surfaces of both track grooves. The purpose of this self-lubricating layer is to minimize frictional resistance and prevent jamming of the cylindrical block as it moves through the track grooves; tin bronze possesses self-lubricating properties.

[0009] Further improvements include the installation of slanted, V-shaped supports at the four corners of the bottom surface of the casing. These slanted supports serve to maintain a larger load-bearing area, significantly improving the stability of the equipment during operation and preventing it from shaking.

[0010] Further improvements include the installation of adjusting feet on the bottom surface of each inclined support leg. The purpose of these adjusting feet is to prevent the equipment from shaking when the ground is uneven, ensuring stable operation.

[0011] Further improvements include a pair of opposing third electric cylinders fixed to the back of the casing, with a first anti-slip rubber head fixed to the piston rod end of each cylinder; and a set of vibrators fixed to the back of each of the two support plates. The function of the third electric cylinders and the first anti-slip rubber heads is to allow the equipment to be lifted laterally, thus tilting it and utilizing gravity to facilitate the sliding of fermented black tea from the various containers, improving collection efficiency. The vibrators not only ensure even distribution of the tea leaves when stacked in the containers but also facilitate the shaking and discharging of the fermented black tea from the containers. These vibrators are commercially available products.

[0012] Further improvements include anti-tipping components installed at the left and right ends of the outer side of the housing; the anti-tipping components include a horizontal plate fixed to the housing, a fourth electric cylinder on the horizontal plate, a fifth electric cylinder on the housing, the tail end of the cylinder body of the fourth electric cylinder is hinged to the horizontal plate, the tail end of the cylinder body of the fifth electric cylinder is hinged to the housing, the head end of the piston rod of the fifth electric cylinder is hinged to the cylinder body of the fourth electric cylinder, and a second anti-slip rubber head is fixed to the piston head end of the fourth electric cylinder. The anti-tipping mechanism here serves to prevent the equipment from tipping over, as the fermented black tea needs to be discharged from the various containers. The equipment is tilted to allow gravity to discharge the tea. To avoid tipping due to the tilted center of gravity, the anti-tipping mechanism prevents the equipment from falling over. The working principle of the anti-tipping mechanism is as follows: Activating the fifth electric cylinder causes the fourth electric cylinder to rotate outwards, creating an angle between the fourth electric cylinder and the side of the housing. Then, activating the piston rod on the fourth electric cylinder causes it to press against the ground through the second anti-slip rubber head, thus preventing the equipment from tipping over. The second anti-slip rubber head provides a non-slip effect, making the equipment more stable when tilted.

[0013] Further improvements include a drying tray below each of the first grid holding plates, with drying openings on each tray matching the size of the first grid holding plate. A set of connecting pipes, each connected to a drying opening, is fixed on the support plate. A set of drying channel pipes is fixed on the shell, and each connecting pipe can be moved and paired to connect to its respective drying channel pipe. The function of the drying trays, drying openings, connecting pipes, and drying channel pipes is to allow the fermented black tea to be dried directly on a single machine after fermentation, improving processing efficiency and product quality. This eliminates the need to transfer the fermented black tea to a drying device, significantly increasing processing efficiency and preventing excessive oxidation and fermentation caused by excessive contact with the external environment. This results in more controllable black tea quality, higher processing efficiency, and better taste.

[0014] Further improvements include the addition of a receiving tray rotatably connected to the left and right sides of the front end of the housing. The top and inner ends of the receiving tray are open, with guide plates hinged at the openings. The side ends of the guide plates are provided with reset guide slopes. A compression spring is installed on the receiving tray to drive the guide plates outward. A discharge port is opened on the outer side of the receiving tray. An inclined block is fixed on the bottom surface of the receiving tray, and the top surface of the inclined block is an inclined surface with the inner side higher than the outer side. A reduction motor that drives the receiving tray to rotate is installed and fixed on the housing. The functions of the receiving tray, guide plate, compression spring, tilting block, tilting surface, and geared motor are as follows: After fermentation and drying are complete, the second electric cylinder moves the tea-containing fermentation mechanism to the left and right outer sides of the casing. Then, the third electric cylinder is activated, causing the equipment to be tilted laterally, facilitating the discharge of the dried tea by gravity. To prevent the equipment from tipping over, the fourth and fifth electric cylinders are activated, causing the fourth electric cylinder to be rotated and opened. Then, the piston rod of the fourth electric cylinder moves outward, blocking the other side of the equipment and preventing it from tipping over. After the equipment is tilted, (simultaneously, the geared motor is activated, thus...) The receiving tray rotates and opens, tilting downwards, causing the guide plate to open under the force of the compression spring (located below the holding pieces). The dried black tea slides down from the holding pieces to the guide plate under gravity, then reaches the inclined surface and is discharged from the outlet into the designated collection box. To accelerate and thoroughly discharge the dried black tea, vibrators are activated. The geared motor drives the receiving tray to rotate and tilt for easy collection. The reset guide slope allows the guide plate to automatically retract into the receiving tray cavity and compress the compression spring when the two receiving trays are reset, storing energy.

[0015] The beneficial effects of this invention are: 1) By setting up sprocket sets, chains, and holding containers, the tea leaves can be continuously moved in a cycle during the fermentation process, so that the tea leaves can be evenly contacted with the fermentation environment and avoid local over-fermentation or under-fermentation. 2) The threaded post and miniature torque motor between the first and second grid plates can precisely adjust the distance between the two grid plates, so that the tea leaves can be compacted and then turned over, allowing the other side of the tea leaves to fully contact the environment. This makes the tea fermentation more complete and even, which is suitable for the tea leaves to ferment evenly and more thoroughly into black tea, and avoids the situation of incomplete fermentation of black tea. 3) By using humidity sensors, temperature sensors, oxygen sensors, and humidification tubes, heating tubes, and oxygenation tubes, the fermentation environment can be monitored and precisely controlled in real time to ensure the stability of the fermentation quality of wild black tea; 4) The cooperation between the track groove and the cylindrical block keeps the container horizontal during movement, preventing the tea leaves from slipping. At the same time, the vibrator helps to distribute the tea leaves evenly. 5) By setting up a pair of sliding tea-holding and fermentation mechanisms, automatic opening and closing doors, and a receiving tray, the automatic feeding and discharging of tea can be achieved, improving production efficiency. Furthermore, the simultaneous movement of the tea-holding and fermentation mechanisms on both sides can not only increase the amount of black tea fermented, but also maintain the stability of the shell and prevent it from tipping over. 6) Through the drying trays, connecting pipes, and drying channel pipes, the tea can be dried in situ after fermentation, reducing material transfer and ensuring the integrity of the tea. 7) The third electric cylinder and anti-tipping device can make the shell tilted and prevent it from tipping over. When discharging the dried black tea, the tilted device can automatically discharge the dried black tea from the tea fermentation mechanism, thus improving the processing efficiency of black tea.

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0019] Referring to the attached diagram: This precision fermentation equipment for wild black tea includes a housing 1, within which a tea-holding and fermentation mechanism 2 is installed. The tea-holding and fermentation mechanism 2 includes a support plate 2a, on which a bracket 2-1 is fixed. Both the inner and outer sides of the bracket 2-1 are equipped with sprocket sets 2-2. Each sprocket set 2-2 includes a sprocket 2-2a rotatably connected to the top and bottom of the bracket 2-1. A chain 2-3 is installed between the inner and outer sprockets 2-2a. A set of longitudinally spaced holding components 2-4 is provided on the left and right sides of each chain 2-3. A drive motor 2-5 for rotating the drive sprocket assembly 2-2 is mounted on the bracket 2-1; each holding component 2-4 includes a first grid holding plate 2-4a hinged to the inner and outer chains 2-3, a second grid holding plate 2-4b above the first grid holding plate 2-4a, and downwardly positioned surrounding plates 2a-4b fixed to the left, right, and inner outer contours of the second grid holding plate 2-4b; cylindrical support rods 2-4c are fixed to the four corners of the first grid holding plate 2-4b, and threaded posts 2-4d are sleeved on each cylindrical support rod 2-4c. Each threaded post 2-4d is threadedly engaged with the second grid holding plate 2-4b. A miniature torque motor 2-4e is fixed to the top of each cylindrical support rod 2-4c. The miniature torque motor 2-4e is a hollow motor, allowing the cylindrical support rod 2-4c to pass through its shaft. This allows the miniature torque motor 2-4e to be fixed by the cylindrical support rod 2-4c without affecting its ability to drive the threaded post 2-4d to rotate. The shafts of each miniature torque motor 2-4e are respectively engaged with the threaded post 2-4d. The top ends are coaxially fixed together. The support plate 2a has a track groove 2a-1. The track groove 2a-1 is consistent with the rotation trajectory of the sprocket 2-2a. The side ends of each first grid holding plate 2-4a are fixed with cylindrical blocks 2-6 that cooperate with the track groove 2a-1. The housing 1 is equipped with a humidity sensor 3, a temperature sensor 4 and an oxygen sensor 5. The back of the housing 1 is equipped with a humidifying pipe 6, a heating pipe 7 and an oxygen supply pipe 8. The bottom of the housing 1 is equipped with an airflow circulation fan 9. The top of the housing 1 is fixed with an exhaust fan 10 that communicates with the cavity of the housing 1.

[0020] The left and right sides of the housing 1 are provided with outlets 1-1. The left and right sides of the housing 1 are hinged with opening and closing doors 1a. The top left and right sides of the housing 1 are provided with first electric cylinders 11. The top of the two opening and closing doors 1a are fixed with first vertical blocks 1b. A pair of oppositely arranged second vertical blocks 1c are fixed on the housing 1. The cylinder tail ends of the two first electric cylinders 11 are respectively ball-jointed with the two second vertical blocks 1c. The piston head ends of the two first electric cylinders 11 are respectively ball-jointed with the two first vertical blocks 1b.

[0021] A pair of tea-holding and fermentation mechanisms 2 are provided inside the housing 1. The two tea-holding and fermentation mechanisms 2 are slidably connected to the housing 1 along the opening and closing door 1a. A pair of second electric cylinders 1d are fixed on the housing 1 to drive the support plate 2a to move.

[0022] Both track grooves 2a-1 have a self-lubricating layer 2a-1a made of tin bronze on their contour surfaces.

[0023] The bottom of the housing 1 is fitted with inclined feet 12 in a figure-eight shape at the four corners.

[0024] Each of the inclined support legs 12 has an adjusting foot 12-1 installed on its bottom surface.

[0025] A pair of opposing third electric cylinders 13 are fixed to the back of the housing 1, and a first anti-slip rubber head 13-1 is fixed to the piston rod head of the third electric cylinder 13; a set of vibrators 19 are fixed to the back of both support plates 2a.

[0026] Anti-tipping components 14 are installed on the left and right ends of the outer side of the housing 1. The anti-tipping components 14 include a horizontal plate 14-1 fixed on the housing 1. A fourth electric cylinder 14-2 is provided on the horizontal plate 14-1. A fifth electric cylinder 14-3 is provided on the housing 1. The tail end of the cylinder body of the fourth electric cylinder 14-2 is hinged to the horizontal plate 14-1. The tail end of the cylinder body of the fifth electric cylinder 14-3 is hinged to the housing 1. The piston rod head end of the fifth electric cylinder 14-3 is hinged to the cylinder body of the fourth electric cylinder 14-2. A second anti-slip rubber head 14-2a is fixed to the piston head end of the fourth electric cylinder 14-2.

[0027] Below each first grid holding plate 2-4a, there is a drying tray 15. Each drying tray 15 has a drying opening 15-1 that matches the size of the first grid holding plate 2-4a. A set of connecting pipes 15-2 that are respectively connected to each drying opening 15-1 are fixed on the support plate 2a. A set of drying channel pipes 16 are fixed on the shell 1. Each connecting pipe 15-2 can be moved and paired to connect to each drying channel pipe 16.

[0028] Material receiving trays 17 are rotatably connected to the left and right sides of the front end of the housing 1. The top and inner ends of the material receiving trays 17 are openings 17-1. A guide plate 17-2 is hinged to the opening 17-1. The side end of the guide plate 17-2 is provided with a reset guide slope 17-2a. A compression spring 17-3 is installed on the material receiving tray 17 to drive the guide plate 17-2 to push outward. A discharge port 17-4 is opened on the outer side of the material receiving tray 17. An inclined block 17-5 is fixed on the bottom surface of the material receiving tray 17. The top surface of the inclined block 17-5 is an inclined surface 17-5a with the inner side higher than the outer side. A reduction motor 18 that drives the material receiving tray 17 to rotate is installed and fixed on the housing 1.

[0029] The housing 1 is equipped with a PLC controller 21 and a control panel 22. The PLC controller 21 is electrically connected to the humidity sensor 3, temperature sensor 4, oxygen sensor 5, humidification actuator of humidification tube 6, heating actuator of heating tube 7, oxygenation actuator of oxygenation tube 8, airflow circulation fan 9, exhaust fan 10, drive motor 2-5, micro torque motor 2-4e, first electric cylinder 11, second electric cylinder 1d, third electric cylinder 13, vibrator 19, fourth electric cylinder 14-2, fifth electric cylinder 14-3, and geared motor 18. The control panel 22 is communicatively connected to the PLC controller 21 and is used to set fermentation parameters, display real-time sensor data and equipment operating status, and realize automated and precise control of the fermentation process.

[0030] Protective sleeves 20 are provided on the housings of the drive motor 2-5, the miniature torque motor 2-4e, the second electric cylinder 1d, and the vibrator 19. These protective sleeves 20 prevent the drive motor 2-5, the miniature torque motor 2-4e, the second electric cylinder 1d, and the vibrator 19 from being affected by humidity and temperature while operating inside the housing, thus ensuring more stable operation and a longer service life for these components.

[0031] The working principle of this invention is as follows: First, the PLC controller 21 controls the start of the first electric cylinder 11, thereby opening the left and right opening and closing doors 1a. Then, the two second electric cylinders 1d are started, pushing the two tea-containing fermentation mechanisms 2 out of the housing 1 to the left and right (at this time, the interface between the connecting pipe 15-2 and the drying channel pipe 16 will separate, such as...). Figure 8As shown), the raw materials (withered and rolled wild tea leaves) are then clamped into the first grid holding plates 2-4a using clips. (After the wild tea leaves are placed in each of the first grid holding plates 2-4a, the vibrator 19 can be activated to help the tea leaves spread evenly.) After the raw materials are placed, the two second electric cylinders 1d drive the two tea-holding fermentation mechanisms 2 to retract into the shell 1, and the opening and closing doors 1a on both sides are closed by the first electric cylinder 11. Subsequently, the temperature, humidity, and oxygen content inside the shell 1 are controlled according to the detected changes in temperature, humidity, and oxygen content. The first grid holding plates 2-4a are not only used to hold the tea leaves, but also provide good upper and lower air circulation, which can accelerate the tea-holding process. Fermentation is crucial for improving fermentation quality. However, the tea leaves pressed at the bottom of the first grid holding plate 2-4a still suffer from poor airflow and temperature control, making it difficult to control the fermentation quality. Therefore, it is necessary to activate the miniature torque motors 2-4e at the four corners of each holding piece 2-4, thereby rotating the threaded columns 2-4d. Since the threaded columns 2-4d engage with the threads of the second grid holding plate 2-4b, the second grid holding plate 2-4b moves closer to the first grid holding plate 2-4a, thus compressing the tea leaves. The purpose is to use the rotation of the chain 2-3 to rotate the holding pieces 2-4 on the left to the right and the holding pieces 2-4 on the right to the left, thereby allowing the second grid holding plate to move closer to the first grid holding plate 2-4a. With plate 2-4b positioned below and the first grid holding plate 2-4a above, the bottom layer of wild tea leaves is turned over to become the top layer. This ensures that each tea leaf receives uniform and constant humidity, temperature, and oxygen concentration, allowing for precise control of fermentation. The first grid holding plate 2-4a and the second grid holding plate 2-4b are brought close together to clamp and rotate the tea leaves, preventing them from falling due to gravity when passing through the arc-shaped areas at the top and bottom of the chain 2-3. After the tea leaves have been turned over, the micro torque motor 2-4e is activated again, driving the threaded column 2-4d to rotate in the opposite direction. This causes the first grid holding plate 2-4a and the second grid holding plate 2-4b to move away from each other, thus allowing the tea leaves to ferment more evenly. After being turned over, the tea leaves undergo precise fermentation at the second grid holding plate 2-4b. The fermentation quality of tea leaves in each area is high. The chain 2-3 is rotated multiple times by the drive motor 2-5 to turn the wild tea leaves over, which greatly improves the fermentation quality of each tea leaf area. After 2-6 hours, when the black tea is fermented, the PLC controller 21 starts to control the drying channel pipe 16 to release high-temperature air, which reaches the drying port 15-1 through the connecting pipe 15-2 to dry the fermented black tea. During the drying process, the drive motor 2-5 needs to be started to turn the fermented black tea over, so that the fermented black tea is dried more evenly in each area, resulting in better quality black tea.After the black tea is dried, the second grid holding plate 2-4b is positioned on the lower side, and the first grid holding plate 2-4a is positioned on the upper side. The dried tea leaves are located at the second grid holding plate 2-4b. Then, the reduction motor 18 is started, which drives the receiving trays 17 on both sides to rotate and tilt downwards. Subsequently, the first electric cylinder 11 and the second electric cylinder 1d are started again, thereby opening the opening and closing doors 1a on both sides and pushing the two tea leaf holding and fermentation mechanisms 2 out from both sides of the housing 1. Then, the third electric cylinder 13 and the anti-tipping component 14 are started, thereby tilting the equipment. At this time, due to gravity, the dried black tea leaves located in each of the second grid holding plates 2-4b, blocked by the three sides of the surrounding plates 2a-4b, fall from the second grid holding plate 2-4b through the gap on one side and fall to the guide plate 17-2 and then fall to the inclined surface 17-5a. Since the receiving tray 17 is tilted downwards (e.g.); Figure 11 As shown), the dried black tea will fall to the designated collection box via tilting block 17-5. In order for the dried black tea in the second grid holding plate 2-4b to fall faster and completely, the vibrator 19 will be activated to transmit vibration force. Each second grid holding plate 2-4b will vibrate, thereby making the dried black tea fall faster and more completely.

[0032] In this embodiment, a PLC controller 21 and a control panel 22 are installed on the housing 1. The PLC controller 21 adopts a Siemens S7-1200 series or equivalent programmable logic controller, and the control panel 22 is a touch-screen industrial LCD screen. The PLC controller 21 has a pre-set fermentation process program. The user sets parameters such as target temperature, humidity, oxygen content, circulation speed, turning interval, drying temperature and duration through the control panel 22. During operation, the humidity sensor 3, temperature sensor 4, and oxygen sensor 5 collect environmental data inside the housing 1 in real time and transmit it to the PLC controller 21. After comparing the measured values ​​with the set values, the PLC controller 21 automatically controls the humidification amount of the humidification tube 6, the heating power of the heating tube 7, the oxygen release of the oxygenation tube 8, and the start / stop and speed of the airflow circulation fan 9 and the exhaust fan 10 to maintain a constant fermentation environment. At the same time, the PLC controller 21 controls the drive motor 2-5 to drive the sprocket group 2-2 and drive the container 2-4 to move cyclically according to the set timing sequence, controls the micro torque motor 2-4e to rotate, and adjusts the first grid container plate. The spacing between 2-4a and the second grid holding plate 2-4b ensures that the tea leaves do not fall off the first grid holding plate 2-4a or the second grid holding plate 2-4b due to gravity during the turning process. The vibrator 19 is controlled to work intermittently, assisting in the even spreading of the tea leaves and controlling the discharge of the dried black tea from each holding piece 2-4. During the feeding, discharging, and drying stages, the PLC controller 21 controls the geared motor 18 to drive the receiving tray 17 to rotate and receive materials. The PLC controller 21 automatically controls the first electric cylinder 11 to open and close the opening and closing door 1a, and the second electric cylinder 17 to open and close the door 1a. The moving cylinder 1d pushes out or pulls back the tea-containing fermentation mechanism 2, the third electric cylinder 13 pushes the equipment laterally, thus tilting the equipment, and the fourth electric cylinder 14-2 and the fifth electric cylinder 14-3 are activated to block the equipment from the other side to prevent it from overturning; the hot air supply of the drying channel pipe 16 is also controlled by the PLC controller 21; through the integration of the above PLC controller 21 and the control panel 22, the fully automatic and high-precision control of the wild black tea fermentation process is realized, which greatly reduces manual intervention and ensures the stability and quality of black tea fermentation.
