Description

Technical Field

[0001] This utility model relates to the field of black tea processing technology, and in particular to a black tea pile fermentation and pressurization device. Background Technology

[0002] The pressurized pile fermentation device for black tea is a key piece of equipment used to control the degree of pile fermentation during the processing of black tea. It applies pressure to the tea leaves to promote the oxidation, polymerization, and transformation of substances within the tea, thereby forming the unique aroma and color of black tea. The device mainly consists of a fixed tank, a pressurization system, and a control system.

[0003] 1. Fixed bucket: As a container for holding tea leaves, its volume and material must meet the temperature and humidity requirements during the pile fermentation process;

[0004] 2. Pressurization system: Includes components such as cylinders and pressure plates. The cylinders drive the pressure plates to apply pressure to the tea leaves inside the fixed container.

[0005] 3. Control system: Used to adjust parameters such as pressurization pressure and time to ensure the stability of the fermentation process;

[0006] 4. Temperature and humidity monitoring module: Real-time monitoring of environmental parameters during the fermentation process, providing data support for process adjustments.

[0007] Currently, various equipment and methods are used in the industry to achieve efficient pile fermentation of black tea. Some manufacturers use simple stacked pressurizing devices, applying pressure by stacking heavy objects; others use electro-hydraulic pressurizing devices, which can precisely control the pressure; and some companies have introduced highly automated intelligent pressurizing systems, which combine temperature and humidity feedback to achieve closed-loop control of the pressurization process.

[0008] However, the above-described implementation methods still have the following problems. Regarding the stability of the fixed barrel, most devices lack effective limiting structures, causing the barrel to easily shake and shift during pressurization. This results in uneven stress on the tea leaves, affecting fermentation consistency and potentially causing abnormal wear on equipment components. In terms of the pressure plate design, existing pressure plates are mostly fixed structures, making quick disassembly difficult. This not only requires significant time for cleaning and maintenance but also prevents flexible replacement of the pressure plate according to the fermentation requirements of different varieties of black tea, limiting the equipment's adaptability to diverse processes. This application addresses this problem by proposing a solution: a black tea pile fermentation pressurization device with limiting structures to restrict the fixed barrel and a detachable pressure plate, thereby improving equipment operational stability, maintenance convenience, and process flexibility. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a pressurizing device for black tea pile fermentation. It solves the problem that most devices do not have an effective limiting structure for the stability of the fixed barrel, which makes the fixed barrel prone to shaking and displacement during pressurization, resulting in uneven stress on the tea leaves and affecting the consistency of fermentation. It may also cause abnormal wear of equipment parts. In terms of the design of the pressurizing plate, existing pressurizing plates are mostly fixed structures, which are difficult to disassemble quickly.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A pressurized fermentation device for black tea includes a frame, a fixed barrel inside the frame, a cylinder inside the frame, a connecting rod fixedly connected to the piston of the cylinder, a pressure plate below the connecting rod, a limit block movably connected inside the frame, a fixed block fixedly connected to the upper surface of the pressure plate, a positioning block movably engaged inside the fixed block, a return spring fixedly connected to the left surface of the positioning block, a connecting block fixedly connected to the lower surface of the connecting rod, a lead screw rotatably connected inside the frame, and the connecting block movably sleeved with the pressure plate.

[0012] Preferably, the connecting block has a limiting groove on its annular side, the limiting groove is movably engaged with the positioning block, the frame has a slot, the slot is movably connected with the limiting block, the lead screw is rotatably disposed in the slot, and the lead screw is threadedly engaged with the limiting block.

[0013] Preferably, the fixed barrel has an arc-shaped groove on its annular side, which is movably engaged with the limiting block; the fixed block has a rectangular groove on its surface, which is movably engaged with the positioning block; the rectangular groove is fixedly connected to the reset spring; and push blocks are fixedly connected to both the front and rear sides of the positioning block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. During the movement of the limiting block, it will engage with the arc-shaped groove on the fixed barrel to limit and fix it, keeping the fixed barrel in a fixed state during pressurization. The limiting structure can ensure that the fixed barrel remains in a fixed position during pressurization, preventing the pressure plate from tilting due to barrel shaking or displacement. If the barrel is unstable, different areas of the tea may be subjected to inconsistent pressure, causing some tea leaves to be pressed too tightly. A stable fixed barrel can ensure that the pressure is evenly transmitted to the tea leaves, ensuring that the density of the tea leaves is consistent, and improving the uniformity of the finished product's appearance and taste.

[0016] 2. By pulling the two push blocks, the fixed positioning block moves together, compressing the return spring. At this time, the positioning block will disengage from the limiting groove opened on the connecting block, opening the limit. The pressure plate can then be disassembled. During tea processing, tea dust, oil, or microorganisms may remain on the surface of the pressure plate. If cleaning is not thorough, it may affect the quality of subsequent batches of products. The detachable structure allows the pressure plate to be removed separately for thorough rinsing and disinfection, ensuring no material residue or bacterial growth, and meeting food safety production standards.

[0023] This application provides a pressurized device for black tea pile fermentation, which effectively solves the problem of the stability of the fixed barrel. Most devices do not have an effective limiting structure, which makes the fixed barrel prone to shaking and displacement during pressurization, resulting in uneven stress on the tea leaves and affecting the consistency of fermentation. It may also cause abnormal wear of equipment parts. In terms of the design of the pressurizing plate, existing pressurizing plates are mostly fixed structures, which are difficult to disassemble quickly. This application designs a pressurized device for black tea pile fermentation with a limiting structure to limit the fixed barrel and a detachable pressurizing plate, thereby improving the stability of equipment operation, ease of maintenance and process flexibility.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that, in terms of the stability of the fixed barrel, most devices do not have an effective limiting structure, which leads to the fixed barrel easily shaking and displacing during pressurization, resulting in uneven stress on the tea leaves, affecting the consistency of fermentation, and may also cause abnormal wear of equipment parts. In terms of the design of the pressure plate, existing pressure plates are mostly fixed structures, which are difficult to disassemble quickly. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a pressurizing device for black tea fermentation, including a frame 1, a fixed barrel 4 inside the frame 1, a cylinder inside the frame 1, a connecting rod 2 fixedly connected to the piston of the cylinder, a pressure plate 3 below the connecting rod 2, a limit block 5 movably connected inside the frame 1, a fixed block 11 fixedly connected to the upper surface of the pressure plate 3, a positioning block 14 movably engaged inside the fixed block 11, a return spring 13 fixedly connected to the left surface of the positioning block 14, a connecting block 9 fixedly connected to the lower surface of the connecting rod 2, and a lead screw 7 rotatably connected inside the frame 1. The connecting block 9 is movably sleeved with the pressure plate 3. In use, tea leaves are placed in the fixed barrel 4, and by activating the cylinder on the frame 1, the piston of the cylinder drives the fixed connecting rod 2 to move together, and the movement of the connecting rod 2 drives the pressure plate 3. The pressure plate 3 moves together, and the downward movement of the pressure plate 3 will pressurize the tea. Before pressing, the fixed bucket 4 containing the tea is clamped into the groove opened on the upper surface of the frame 1. At this time, by rotating the screw 7, the limiting block 5 sleeved on it will be moved by the thread action. During the movement, the limiting block 5 will engage with the arc groove 6 opened on the fixed bucket 4, thereby limiting and fixing it, so that the fixed bucket 4 remains fixed during the pressurization process. The limiting structure can ensure that the fixed bucket 4 remains fixed in position during pressurization, preventing the pressure plate 3 from tilting due to the shaking or displacement of the bucket. If the bucket is unstable, different areas of the tea may be subjected to inconsistent pressure, causing some tea to be pressed too tightly. The stable fixed bucket 4 can make the pressure evenly transmitted to the tea, ensuring the density of the tea is consistent, and improving the appearance and taste uniformity of the finished product.

[0027] A limiting groove 10 is formed on the annular side of the connecting block 9, and the limiting groove 10 is movably engaged with the positioning block 14. A slot 8 is formed inside the frame 1, and the slot 8 is movably connected with the limiting block 5. The lead screw 7 is rotatably set in the slot 8, and the lead screw 7 is threadedly engaged with the limiting block 5. An arc-shaped groove 6 is formed on the annular side of the fixed barrel 4, and the arc-shaped groove 6 is movably engaged with the limiting block 5. A rectangular groove 12 is formed on the surface of the fixed block 11, and the rectangular groove 12 is movably engaged with the positioning block 14. The rectangular groove 12 is fixedly connected to the return spring 13. Push blocks are fixedly connected to both the front and rear sides of the positioning block 14. 15. By pulling the two push blocks 15, the fixed positioning block 14 is moved together, compressing the return spring 13. At this time, the positioning block 14 will disengage from the limiting groove 10 opened on the connecting block 9 and open the limit. At this time, the pressure plate 3 can be disassembled. In tea processing, tea dust, oil or microorganisms are easily left on the surface of the pressure plate 3. If the cleaning is not thorough, it may affect the quality of subsequent batches of products. The detachable structure allows the pressure plate 3 to be taken out separately for all-round rinsing and disinfection to ensure that there is no material residue or bacterial growth, which meets the food safety production standards.

[0028] Among them, frame 1: as the main body of the device, it is used to install and fix components such as barrel 4 and cylinder, providing support for the overall structure, ensuring the stable assembly of each component, and is the basic framework for the operation of the device.

[0029] Connecting rod 2: connects the cylinder piston and the pressure plate 3, transmits the cylinder power, drives the pressure plate 3 to move up and down, and realizes the pressure operation of the tea in the fixed barrel 4;

[0030] Pressure plate 3: Under the action of connecting rod 2, pressure is applied to the tea leaves in the fixed barrel 4. Its detachable design makes it easy to clean, maintain and replace, ensuring the quality of tea processing and the compatibility of the process.

[0031] Fixed bucket 4: It carries tea leaves and provides space for fermentation. An arc-shaped groove 6 is opened on the side and engages with the limiting block 5. The limiting ensures stability when pressurized and makes the tea leaves evenly stressed.

[0032] Limiting block 5: engages with the arc-shaped groove 6 of the fixed barrel 4 to limit the shaking and displacement of the fixed barrel 4 during the pressurization process, ensuring stable pressurization and improving the consistency of tea fermentation;

[0033] Arc-shaped groove 6: It is opened on the side of the fixed barrel 4 and works with the limiting block 5 to limit and fix the fixed barrel 4. It is a key structure for the stability of the fixed barrel 4 and ensures uniform pressure transmission.

[0034] Lead screw 7: Rotatably set in slot 8, threadedly connected to limit block 5. By rotating lead screw 7, limit block 5 is driven to move, thereby limiting and unlocking fixed barrel 4;

[0035] Slot 8: Located inside the frame 1, it provides a moving track for the limit block 5. Together with the lead screw 7, it enables the limit block 5 to move accurately and engage with the arc-shaped groove 6 of the fixed barrel 4, ensuring precise positioning.

[0036] Connecting block 9: It is fixed to the connecting rod 2. The movable sleeve design makes the pressure plate 3 detachable. The limiting groove 10 on its annular side is engaged with the positioning block 14 to fix the pressure plate 3.

[0037] Limiting groove 10: It is formed on the annular side of the connecting block 9 and engages with the positioning block 14 to limit the displacement of the pressure plate 3, ensuring stability during pressurization. The pressure plate 3 can be removed by disengaging from the engagement.

[0040] Reset spring 13: connects positioning block 14 and rectangular groove 12. After push block 15 pulls positioning block 14, it is compressed and stores force. When push block 15 is released, it pushes positioning block 14 to reset, so as to achieve snap-fit ​​fixation with limit groove 10.

[0041] Positioning block 14: It is movable and snapped into the fixed block 11, and snapped into the limiting groove 10 of the connecting block 9 to fix the pressure plate 3. It can be disengaged by pushing block 15 to realize the disassembly of the pressure plate 3.

[0042] Push block 15: Fixed on the front and rear sides of the positioning block 14, so that the operator can manually pull the positioning block 14, compress the reset spring 13, release the positioning block 14 from the limit groove 10, and facilitate the disassembly of the pressure plate 3.

[0043] Working principle:

[0044] During use, tea leaves are placed in the fixed container 4. The cylinder on the frame 1 is activated, causing the piston to move the fixed connecting rod 2. This movement of the connecting rod 2 moves the pressure plate 3, which then pressurizes the tea leaves. Before pressurization, the fixed container 4 containing the tea leaves is engaged in a groove on the upper surface of the frame 1. Rotating the lead screw 7 causes the limiting block 5, which is fitted onto it, to move under the action of the thread. During this movement, the limiting block 5 engages with the arc-shaped groove 6 on the fixed container 4, thus fixing it in place and ensuring the container 4 remains fixed during pressurization. This limiting structure ensures the container 4 remains in a fixed position during pressurization, preventing the pressure plate 3 from tilting due to container shaking or displacement. Stable pressure distribution is crucial because different areas of the tea leaves may experience inconsistent pressure, resulting in some leaves being overly compressed. The stable fixed barrel 4 ensures that the pressure is evenly distributed to the tea leaves, guaranteeing consistent density and improving the uniformity of the finished product's appearance and taste. By pulling the two push blocks 15, the fixed positioning block 14 moves together, compressing the return spring 13. At this point, the positioning block 14 disengages from the limiting groove 10 on the connecting block 9, opening the limit. The pressure plate 3 can then be disassembled. During tea processing, tea dust, oil, or microorganisms may easily remain on the surface of the pressure plate 3. If cleaning is not thorough, it may affect the quality of subsequent batches of products. The detachable structure allows the pressure plate 3 to be removed separately for thorough rinsing and disinfection, ensuring no material residue or bacterial growth, and meeting food safety production standards.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation.
