Description

Technical Field

[0001] This application relates to the field of tea fermentation equipment, and in particular to a multi-layer stacked fermentation equipment suitable for Jiuqu Hongmei tea. Background Technology

[0002] Jiuqu Hongmei belongs to the black tea category. In its production process, fermentation is the key process that determines the quality of the tea. It is necessary to strictly control the temperature, humidity, oxygen content and stacking state of the tea leaves in the fermentation environment in order to ensure that the tea leaves develop a unique aroma and taste.

[0003] Existing multi-layer fermentation equipment for Jiuqu Hongmei tea typically employs a frame design with fixed layer spacing, where multiple shelves are fixed by welding or bolts to support the fermentation trays. This type of structure has the following core drawbacks: the fixed shelf height in the frame structure necessitates operators adjusting their posture according to different shelf heights when loading or removing fermentation trays, resulting in high labor intensity. Furthermore, operating on higher shelves can easily lead to tray tilting and tea spillage. Utility Model Content

[0004] To address the issues of high labor intensity for operators and difficulty in placing fermentation trays, this application provides a multi-layer stacked fermentation device suitable for Jiuqu Hongmei.

[0005] The multi-layer stacked fermentation equipment for Jiuqu Hongmei provided in this application adopts the following technical solution:

[0006] A multi-layer stacked fermentation device suitable for Jiuqu Hongmei (a type of plum) includes a main body, characterized in that: a placement device is provided inside the main body, the placement device including two symmetrically distributed scissor-type frames, a hanger located on the two scissor-type frames, a multi-layer combined tray device installed on the hanger, and a drive mechanism for driving the extension and retraction of the scissor-type frames; each scissor-type frame includes multiple vertically hinged X-shaped frames, each X-shaped frame having a hanger installed at its upper end, and the drive mechanism connected to the lowermost X-shaped frame; the multi-layer combined tray device includes multiple vertically arranged fermentation trays, each fermentation tray having a connecting part at its upper end, and each fermentation tray except the lowermost fermentation tray having a connecting groove at its lower end for the connecting part to slide horizontally into, the height of the connecting groove being higher than the height of the connecting part, allowing the multi-layer combined tray device to have a stacked state and an unfolded state, in the stacked state, the connecting part of the lower fermentation tray of adjacent fermentation trays abuts against the top of the connecting groove, and in the unfolded state, the connecting part of the lower fermentation tray of adjacent fermentation trays abuts against the bottom of the connecting groove.

[0007] By adopting the above technical solution, the scissor-lift frame forms a telescopic structure through multiple X-shaped hinges. Combined with a drive mechanism, it enables synchronous lifting and lowering of multiple layers of the rack. Lowering the placement device facilitates the placement of fermentation trays by operators. Furthermore, the multi-layer combined tray device allows for the simultaneous placement of multiple fermentation trays. The low height of each tray effectively improves space utilization. Since the tea leaves laid in each fermentation tray are relatively thin, there is no need to install vibrators or stirring devices on the trays, saving costs. The fermentation trays are typically 3cm high.

[0008] Optionally, each of the X-shaped frames is rotatably connected to a support rod, which is used to support the lowest fermentation tray.

[0009] By adopting the above technical solution, the support rods can be set up to allow the multi-layer combined pallet device to unfold slowly.

[0010] Optionally, the main body of the device is rotatably connected to a main shaft and a first motor that drives the main shaft to rotate. Several support members are fixed on the main shaft. For each X-shaped frame, except for the uppermost and lowermost fermentation trays, each fermentation tray corresponds to a support member. The corresponding support member is located below the corresponding fermentation tray after the main shaft rotates.

[0011] By adopting the above technical solution, the fermentation tray is generally made of stainless steel. If the strength is insufficient, the above support rods can be used to provide supplementary support for the fermentation tray.

[0012] Optionally, the drive mechanism includes a second motor, a screw connected to the output shaft of the second motor and driven by the second motor, a nut block threadedly connected to the screw, and a connecting frame connecting the nut block and the X-shaped frame. Rollers are mounted on the connecting frame, and a guide rail for the rollers to move is installed inside the main body of the equipment.

[0013] By adopting the above technical solution, and using a transmission structure of a second motor, screw, and nut block, the rotational motion of the second motor is converted into the linear motion of the nut block. This allows for precise control of the extension and retraction of the scissor frame, thereby achieving precise adjustment of the hanger height and meeting the strict requirements of Jiuqu Hongmei fermentation for layer spacing. Secondly, it ensures operational stability. The rollers on the connecting frame cooperate with the guide rails inside the main body of the equipment, limiting the movement trajectory of the nut block and the connecting frame, avoiding deviation or jamming during transmission, ensuring the synchronous lifting of multiple hangers, and preventing tray tilting due to uneven lifting of individual layers. Thirdly, it offers ease of operation. The second motor drive replaces manual adjustment, reducing the labor intensity of operators and facilitating subsequent linkage with the controller for automated adjustment, thereby improving production efficiency.

[0014] Optionally, the main body of the device is a closed cavity structure with an openable sealing door on one side. The sealing door has an observation window, and the placement devices are evenly distributed inside the main body of the device along its height.

[0015] By adopting the above technical solutions, the closed cavity structure can effectively isolate the entry of external air, dust, and impurities, avoiding contamination of Jiuqu Hongmei. At the same time, it reduces the loss of temperature and humidity inside the cavity, providing a stable and sealed environment for fermentation, which meets the process requirements of controlling oxygen content in Jiuqu Hongmei fermentation. The observation window allows monitoring without opening the sealed door, avoiding damage to the fermentation environment due to frequent door opening. Thirdly, the space is evenly distributed, with the placement devices evenly distributed along the height direction, making the temperature and humidity distribution of each layer inside the cavity more uniform, ensuring that the fermentation progress of Jiuqu Hongmei on different shelves is consistent, and improving product uniformity.

[0016] Optionally, the main body of the device includes a temperature control component and a controller; the temperature control component includes a temperature sensor and a heating device, the heating device being an electric heating device, and both the temperature sensor and the heating device being electrically connected to the controller, the controller controlling the start and stop of the heating device according to the temperature sensor.

[0017] By adopting the above technical solutions, the temperature sensor can collect temperature data inside the cavity in real time, providing a basis for temperature regulation and avoiding the impact of excessively high or low temperatures on the fermentation quality of Jiuqu Hongmei (e.g., excessively high temperatures can easily cause tea to deteriorate, while excessively low temperatures will slow down fermentation); secondly, it provides automated temperature regulation, with the controller automatically controlling the start and stop of the electric heating device based on the feedback signal from the temperature sensor, without the need for manual intervention, improving the accuracy and stability of temperature control, while reducing human operation errors; thirdly, it has strong adaptability, with the electric heating device featuring fast heating speed and high temperature control accuracy, enabling it to quickly respond to temperature regulation needs and adapt to the temperature requirements of different fermentation stages of Jiuqu Hongmei (e.g., the initial fermentation stage requires increased temperature, while the middle stage requires stable constant temperature).

[0018] Optionally, the main body of the device further includes a humidity control component, which includes a humidity sensor and a humidification device. The humidity sensor and the humidification device are both electrically connected to the controller, and the controller controls the start and stop of the humidification device according to the humidity sensor.

[0019] By adopting the above technical solutions, the fermentation of Jiuqu Hongmei tea requires high humidity (generally, high humidity needs to be maintained to promote microbial activity). The humidity sensor collects humidity data in real time, and the controller automatically controls the start and stop of the humidification device accordingly to ensure that the humidity in the chamber is stable within a suitable range, avoiding the tea leaves from drying out due to excessively low humidity or from becoming moldy due to excessively high humidity. Secondly, the environment is synergistically regulated, with humidity control and temperature control working together to form a stable and suitable fermentation microenvironment, providing a guarantee for the formation of the aroma and color of Jiuqu Hongmei tea and improving product quality. Thirdly, the degree of automation is improved, eliminating the need for frequent manual spraying of water mist to adjust humidity, reducing labor intensity, and avoiding excessive humidity fluctuations caused by manual adjustment.

[0020] Optionally, the main body of the equipment also includes a ventilation component, which includes an air inlet duct and an air outlet duct. The air inlet duct is equipped with a solenoid valve and an exhaust fan, and the air outlet duct is equipped with a one-way valve.

[0021] By adopting the above technical solution, the microbial activities during the fermentation of Jiuqu Hongmei require oxygen and produce waste gases such as carbon dioxide. The exhaust fan in the air inlet duct can introduce fresh air, and the exhaust duct can discharge waste gas, ensuring sufficient oxygen in the cavity and preventing the accumulation of waste gas from affecting the fermentation process. The solenoid valve in the air inlet duct can control the ventilation volume and timing, and can adjust the ventilation state according to the oxygen demand of Jiuqu Hongmei at different fermentation stages (such as requiring a small amount of ventilation in the early stage of fermentation and appropriately increasing the ventilation volume in the middle stage). The one-way valve in the exhaust duct can prevent outside air, dust or waste gas from flowing back into the cavity, avoiding pollution of the fermentation environment, while ensuring stable pressure in the cavity.

[0022] Optionally, a filter screen is also installed at the inlet of the air intake duct.

[0023] By adopting the above technical solution, a filter screen is installed at the inlet of the air intake duct to achieve the main air purification effect: filtering out dust, impurities, microorganisms and other pollutants in the fresh air entering the cavity, preventing these pollutants from adhering to the surface of the Jiuqu Hongmei plum and affecting its quality, while preventing impurities from clogging the internal pipes of the equipment or affecting the normal operation of components such as sensors and heating devices, thus extending the equipment maintenance cycle.

[0024] Optionally, a circulating fan is installed inside the main body of the equipment.

[0025] By adopting the above technical solutions, the circulating fan can drive the air circulation within the main body of the equipment, avoiding temperature and humidity differences between upper and lower layers and front and back areas caused by multi-layer stacking, ensuring that all Jiuqu Hongmei plums are in the same fermentation environment, and improving the uniformity of product quality; the circulating fan accelerates the air flow within the cavity, enabling the fresh air introduced by the air inlet duct to quickly diffuse throughout the entire cavity, while simultaneously allowing the exhaust gas to quickly collect and be discharged through the air outlet duct, improving ventilation efficiency; the air circulation can prevent condensation from forming in localized areas within the cavity due to excessively low temperatures, preventing condensation from dripping onto the surface of the Jiuqu Hongmei plums and causing localized mold growth or uneven quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Structural performance optimization: By driving the scissor frame to retract and lower the position of the hanging rack, it is convenient to manually place the fermentation trays; at the same time, the use of multi-layer combination tray device can effectively improve space utilization and eliminate the need for additional vibration stirring device to process tea, saving costs;

[0028] 2. Precise Fermentation Environment Control: Ensuring Uniform Quality. A closed chamber ensures environmental sealing, isolating external contaminants. A collaborative system of temperature and humidity sensors, controllers, and actuators enables precise and automated temperature and humidity control, adapting to the temperature and humidity requirements of different fermentation stages of Jiuqu Hongmei plums. Combined with ventilation components, filters, and circulating fans, oxygen replenishment, waste gas exhaust, air purification, and circulation are completed, eliminating differences in temperature, humidity, and gas distribution within the chamber, preventing localized condensation, and providing a consistent high-quality fermentation environment for all Jiuqu Hongmei plums.

[0029] 3. Operation and Monitoring Guarantee: Improved production efficiency and convenience. The openable, sealed door facilitates pallet loading and unloading, while the observation window allows for real-time monitoring of the fermentation status, avoiding frequent door openings that could damage the environment. The design incorporates a second motor drive and automated temperature and humidity control, reducing manual intervention, improving production efficiency, minimizing operational errors, and ensuring the stability and controllability of the fermentation process.

[0040] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0041] This application discloses a multi-layer stacked fermentation device suitable for Jiuqu Hongmei, including the main body of the device 1.

[0042] like Figure 1 The main body of the equipment 1 is a closed cavity structure with an openable sealed door 2 on one side. An observation window 3 is provided on the sealed door 2. Placement devices 4 are installed inside the main body 1, evenly distributed along its height. The observation window 3 is made of transparent tempered glass, allowing staff to observe the fermentation of tea leaves inside the equipment in real time. The inner wall of the main body 1 is equipped with an insulation layer made of polyurethane insulation material, which reduces heat exchange between the inside and outside of the main body 1, improves the equipment's insulation performance, and reduces energy consumption.

[0043] The placement device includes two symmetrically distributed scissor lift frames 5, hangers 7 located on the two scissor lift frames 5, and a drive mechanism for extending and retracting the scissor lift frames 5. Each hanger 7 is equipped with a multi-layer combined tray device. The multi-layer combined tray device includes multiple fermentation trays 8 arranged vertically. The fermentation tray 8 is a rectangular structure with an open top, and its bottom is evenly provided with several ventilation holes (not shown in the figure). The diameter of the ventilation holes is 0.5mm-1mm to facilitate air circulation, ensure the supply of oxygen during the tea fermentation process, and prevent tea leaves from falling out of the ventilation holes.

[0044] Specifically, such as Figure 6 Each fermentation tray 8 has a connecting part 9 at its upper end. In this embodiment, the connecting parts 9 are located on both sides of the upper end of the fermentation tray 8. The connecting parts 9 are flat plate structures. Except for the bottommost fermentation tray 8, each fermentation tray has a connecting groove 10 at its bottom for the connecting part 9 to slide horizontally into. Two connecting grooves 10 are provided. The cross-section of the connecting groove 10 is similar to a C-shape. The connecting groove 10 is integrally formed with the connecting part 9 and the fermentation tray 8. The height of the connecting groove 10 is higher than the height of the connecting part 9, so that the multi-layer combined tray device can be in a stacked state and an unfolded state. In the stacked state, the connecting part 9 of the lower fermentation tray 8 of the adjacent fermentation tray 8 abuts against the top of the connecting groove 10. In the unfolded state, the connecting part 9 of the lower fermentation tray 8 of the adjacent fermentation tray 8 abuts against the bottom of the connecting groove 10. The hanger 7 has a slide rail 11 for the connecting part 9 to slide into.

[0045] like Figure 7 Each scissor lift frame 5 includes multiple vertically hinged X-shaped frames 6. A hanger 7 is mounted on the upper end of each X-shaped frame 6. Each X-shaped frame 6 is formed by two connecting rods hinged in the middle. The X-shaped frames 6 on both sides are connected by a connecting shaft 14, which is located at the hinge position of the X-shaped frame 6 to ensure the stability of the overall placement device. Figure 6 The hanger 7 includes an integrally formed rectangular frame 12, a sleeve 13, and a slide rail 11. The slide rail 11 has an L-shaped cross-section and is fixed below the rectangular frame 12. One end of the slide rail 11 is closed, so that when the connecting part 9 of the fermentation tray 8 is pushed in, it is easy to know that it has been pushed into place. Figure 7 The sleeve 13 is fitted onto one of the connecting shafts 14 and can rotate relative to the connecting shaft 14. The other connecting shaft 14 passes through the rectangular frame 12 and abuts against the rectangular frame 12. When the X-shaped frame 6 extends or retracts, the connecting shaft 14 can slide horizontally within the rectangular frame 12. The sleeve 13 is partially located within the rectangular frame 12. For each of the two X-shaped frames 6 on each layer, the rectangular frame 12 and the slide rail 11 are provided for each X-shaped frame 6, while the sleeve 13 is shared. The sleeve 13 connects the rectangular frames 12 on the two X-shaped frames 6 together, and the sleeve 13 is welded to the rectangular frame 12.

[0046] like Figures 7-8Each of the X-shaped frames 6 is rotatably connected to a support rod 15, which supports the lowest fermentation tray 8. For structural simplicity, the support rod 15 is shared by the X-shaped frames 6 on both sides of the same layer. The connecting part 9 of the uppermost fermentation tray 8 of each X-shaped frame 6 slides horizontally into the slide rail 11 to connect the fermentation tray 8 to the hanger 7.

[0047] like Figure 4 The main body 1 of the equipment is rotatably connected to a main shaft 26 and a first motor 16 that drives the main shaft 26 to rotate. The main shaft 26 is vertically arranged, and several support members 21 are fixed on the main shaft 26. The support member 21 is a long strip-shaped plate structure, and the support member 21 is perpendicular to the main shaft 26. For each X-shaped frame 6, except for the top and bottom fermentation trays 8, each fermentation tray 8 corresponds to a support member 21. The corresponding support member 21 is located below the corresponding fermentation tray 8 after the main shaft 26 rotates. More specifically, after the fermentation tray 8 is in the unfolded state, the corresponding support member 21 is located below the corresponding fermentation tray 8 after the main shaft 26 rotates. In this embodiment, since the bottom fermentation tray 8 is supported by the support rod 15, the bottom and top fermentation trays 8 do not have additional corresponding support members 21, while the remaining middle fermentation trays 8 all have corresponding support members 21. Before the fermentation tray 8 is placed, the support member 21 is offset from the fermentation tray 8 in a top view. Specifically, the support member 21 is parallel to the connecting shaft 14 and is located on the side of the fermentation tray 8 away from the sealing door 2.

[0048] like Figure 5The drive mechanism is connected to the lowest X-shaped frame 6. The drive mechanism includes a second motor 22, a screw 17 connected to the output shaft of the second motor 22 and driven by the second motor 22, a nut block 18 threadedly connected to the screw 17, and a connecting frame connecting the nut block 18 to the X-shaped frame 6. Rollers 19 are mounted on the connecting frame, and a guide rail 20 for the rollers 19 to move is installed inside the main body 1. More specifically, the guide rail 20 is fixed to the main body 1 by bolts or welding, and the connecting frame is rotatably connected to the X-shaped frame 6 by pins. Four rollers 19 are arranged on the connecting frame, two on each side, for more stable movement. The nut block 18 is integrally machined onto the connecting frame. The connecting frame is actually composed of two connecting rods 23 with nut blocks 18 and connecting plates 24 located at both ends of the connecting rods 23. Two connecting rods 23 are provided, and the connecting plates 24 are fixed to the connecting rods 23 (by bolts or welding). The rollers 19 are rotatably connected to the connecting plates 24. The second motor 22 of the drive structure is covered by a protective housing 37. One end of the screw 17 extends from inside the protective housing 37 and is threadedly connected to the nut block 18. The protective housing 37 mainly reduces the impact of moisture and temperature on the second motor 22. The second motor 22 can be a special waterproof and heat-resistant second motor 22 adapted to this environment (such as the Dongli 4IK25GN-S3-Y3 second motor 22 with an IP65 protection rating and a temperature resistance of 200℃, or the Yaskawa SGD7S-120A30B202 waterproof servo second motor 22 with an IP67 rating, etc.).

[0049] The main body 1 of the equipment includes a temperature control component and a controller. The temperature control component includes a temperature sensor and a heating device 27, which is an electric heating device, specifically an electric heating copper tube. The electric heating copper tube is located on the side of one of the scissor-type frames 5, and the electric heating copper tube is bent back and forth and offset from the scissor-type frame 5 to avoid affecting the operation of the scissor-type frame 5. The temperature sensor and the heating device 27 are both electrically connected to the controller, and the controller controls the start and stop of the heating device 27 according to the temperature sensor. The main body 1 of the equipment also includes a humidity control component, which includes a humidity sensor and a humidifier. The humidity sensor and the humidifier are both electrically connected to the controller, and the controller controls the start and stop of the humidifier according to the humidity sensor. The humidifier is an ultrasonic industrial humidifier, specifically the Bio-YDH-809EB model. The spray holes of the humidifier are located on the side wall of the other scissor-type frame 5, and the spray heads 28 are arranged in a row corresponding to each fermentation tray 8. The height of each row of spray heads 28 is higher than the top opening height of the corresponding fermentation tray 8. For a simpler structure, this application uses a temperature and humidity sensor 29, model XY-MD02, which combines the functions of a temperature sensor and a humidity sensor, to monitor the temperature and humidity inside the main body 1 of the device in real time.

[0050] The controller is a PLC controller. It is electrically connected to all electrical equipment, including the temperature and humidity sensor 29, heating device 27, humidification device, and exhaust fan 33. The outer surface of the main body 1 of the equipment has a control display screen 25, which is electrically connected to the controller. The control display screen 25 is used by the operator to set fermentation parameters, view real-time fermentation data, and monitor the equipment's operating status.

[0051] like Figures 2-3 The main body of the equipment 1 also includes a ventilation assembly, which includes an air inlet duct 30 and an air outlet duct 31. A solenoid valve 32 and an induced draft fan 33 are installed on the air inlet duct 30, and a one-way valve 34 is installed on the air outlet duct 31. A filter screen 35 is also installed at the inlet of the air inlet duct 30. The filter screen 35 is an activated carbon filter screen, which can filter the air entering the main body of the equipment 1 and remove impurities and odors from the air.

[0052] like Figure 3 The main body 1 of the equipment is equipped with a circulating fan 36, with one circulating fan 36 at the top and one at the bottom. The circulating fan 36 can drive the air circulation in the main body 1 of the equipment to avoid temperature and humidity differences between the upper and lower layers and between the front and back areas due to multi-layer stacking, and ensure that all Jiuqu Hongmei are in the same fermentation environment, thereby improving the uniformity of product quality.

[0053] The working principle of a multi-layer stacked fermentation device for Jiuqu Hongmei tea, as described in this application embodiment, is as follows: Before entering the fermentation device, the multi-layer combined tray device is already prepared and stacked (the preparation process involves laying tea leaves on the bottom fermentation tray 8, then pushing the upper fermentation tray 8 horizontally in, and then laying tea leaves again, repeating this process until the top layer). The operator first sets the parameters required for Jiuqu Hongmei fermentation, such as temperature, humidity, fermentation time, and ventilation, through the control display screen 25; then, the sealing door 2 is opened, and the control button is pressed. The second motor 22 starts, driving the scissor frame 5 to retract and descend, at which time the hanging frame 7 also descends; the multi-layer combined tray device with Jiuqu Hongmei tea leaves (after kneading) is pushed into the slide rail 11 of the hanging frame 7. At this time, the connecting part 9 of the top fermentation tray 8 slides into the slide rail 11, and the bottom fermentation tray 8 abuts against the support rod 15. Close the sealing door 2; press the button again, and the second motor 22 starts, driving the scissor-type frame 5 to unfold and rise to the initial position. During this process, the fermentation trays 8 gradually unfold due to gravity, and eventually the adjacent fermentation trays 8 maintain a gap (finally as shown). Figure 9Due to gravity, the connecting part 9 of the fermentation tray 8 will move from the top to the bottom of the connecting groove 10 to complete the unfolding. Then, the first motor 16 starts to drive the main shaft 26. The main shaft 26 drives the support 21 to rotate to the bottom of the corresponding fermentation tray 8 (the support 21 rotates 45 degrees, which can be understood as rotating from the side of the fermentation tray 8 to the bottom of the fermentation tray 8. The support 21 is initially parallel to the connecting shaft 14 and located on the side of the fermentation tray 8 away from the sealing door 2). The equipment is then started via the control display screen 25. The controller controls the operation of each component according to preset parameters: the heating device 27 and the humidification device in the temperature and humidity control component work together to adjust the temperature and humidity inside the main body 1 of the equipment to the preset range; the exhaust fan 33 in the ventilation component starts to introduce filtered air from the outside into the main body 1 of the equipment, and at the same time, the air volume is adjusted by the solenoid valve 32 to ensure that the oxygen content inside the main body 1 of the equipment is suitable; during the fermentation process, the temperature and humidity sensor 29 transmits the detection data to the controller in real time, and the controller adjusts the operating status of each component in real time according to the detection data to ensure a stable fermentation environment; the staff can observe the fermentation of the tea in real time through the observation window 3; after the fermentation is completed, the equipment automatically stops running, and the staff can open the sealed door 2 and take out the tea in the fermentation tray 8.
