Description

Technical Field

[0001] This utility model relates to the field of tea stir-frying technology, and more specifically, to a stir-frying device for tea production. Background Technology

[0002] In existing technologies, the stir-frying device, as a fundamental piece of equipment in the tea processing field, has a decisive impact on the quality of tea. In traditional processes, tea is mostly stir-fried manually. This method not only requires workers to have rich experience and skills, but also requires them to maintain a high level of concentration for long periods of time. The manual stir-frying process usually requires workers to stand in a high-temperature environment for several hours continuously, with their hands performing repetitive movements. This not only places a heavy burden on their bodies, leading to a high incidence of occupational diseases, but also results in low manual efficiency and limited output per unit time. At the same time, it is difficult to guarantee the consistency and stability of manual operation. Especially after working for a long time, worker fatigue directly affects the uniformity of stir-frying and the control of heat, resulting in large fluctuations in tea quality, low standardization, and significant batch-to-batch differences. This makes it difficult to meet the requirements of modern tea production for quality stability and large-scale production, and it is time-consuming, labor-intensive, and has adverse effects.

[0003] Secondly, in existing technologies, some teas require a relatively sealed environment during stir-frying to prevent aroma loss. This is because the aromatic substances in tea are mostly volatile components, which are crucial to the flavor and quality of the tea. During stir-frying, as the temperature rises, the evaporation of moisture inside the tea intensifies, and organic matter undergoes a series of complex chemical reactions, producing a large amount of water vapor and other gaseous substances. However, in a completely sealed environment, these gases cannot be released in time, leading to a continuous increase in internal pressure. This not only affects heat transfer efficiency and the uniformity of stir-frying but may also cause equipment deformation or even safety hazards due to excessive pressure. To solve this contradiction, a one-way sealing device is needed to achieve automatic venting, ensuring that excess pressure is released while preserving aroma. However, the one-way sealing devices commonly found on the market generally have a fixed venting threshold, which is difficult to adjust once installed. This design is extremely inflexible when facing different tea varieties, different batches of raw material moisture content, different seasonal climate conditions, and diverse process requirements. When the process changes, this fixed threshold device cannot be adjusted accordingly, either leading to excessive aroma loss affecting quality or causing insufficient pressure accumulation to trigger the venting mechanism, affecting thermal efficiency and safety, resulting in adverse effects.

[0004] Furthermore, while some improved equipment has achieved flexible adjustment of the pressure relief threshold to address the aforementioned issues, theoretically adapting to the changing needs of different types of tea and different processing stages, the structural design of these improved devices is too simple and crude, resulting in serious stability defects. First, the adjustment mechanism often lacks effective locking devices and anti-loosening designs. During long-term operation, the continuous vibration of the stirring mechanism will gradually cause the adjustment components to loosen. Second, the periodic impact of gas inside the pipeline will repeatedly exert mechanical impact on the adjustment mechanism, leading to minute displacements of the precision adjustment components over time. The combined effect of these factors can easily cause unpredictable displacement changes in the components after the threshold has been adjusted. Especially during long-term continuous production, this deviation will gradually accumulate and eventually cause a significant deviation between the actual pressure relief threshold and the set value. When the carefully adjusted pressure relief threshold changes, it will not only directly affect the consistency of tea quality but may also affect the equipment's lifespan and operational safety due to improper pressure control. At the same time, it increases the difficulty of monitoring and the frequency of manual intervention during the production process, reduces production efficiency and product standardization, and brings serious adverse effects.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a stir-frying device for tea processing, which has the following beneficial effects:

[0018] 1. The stir-frying device, through the ingenious coordination of the mounting frame, heating base, driven wheel, driving wheel, motor, pot body, and stir-frying rack, achieves fully automated operation of the tea stir-frying process. It completely solves the technical problems of traditional manual stir-frying being time-consuming, labor-intensive, and lacking standardization. The rotating connection design between the mounting frame and the pot lid makes adding tea leaves simple and convenient. The motor drives the driving wheel to rotate, and through precise engagement with the driven wheel, it ensures the stable and efficient operation of the stir-frying rack, achieving uniform stir-frying of the tea leaves. The detachable handle on the side of the pot body facilitates the disassembly and movement of the pot body without affecting the overall sealing. This mechanized stir-frying method significantly improves the standardization and production efficiency of tea processing, ensures batch-to-batch quality consistency, and effectively avoids the occupational disease risks caused by long-term manual operation by workers, providing reliable technical support for the modernization of tea processing.

[0019] 2. The pressure relief device consists of a connecting pipe, a working sleeve, an output pipe, a fixed rod, a top block, a sealing plate, a moving sleeve, a mating sleeve, a fixed frame, and a movable spring. It solves the technical problem of the contradiction between sealing and venting during traditional tea stir-frying. The precise fit between the sealing plate, sealing strip, and sealing groove creates a sealed frying environment under normal conditions, effectively preventing the loss of tea aroma. When the pressure inside the pot exceeds the set threshold, the gas pushes the sealing plate to slide along the guide rail and guide groove, overcoming the elasticity of the movable spring and causing the sealing strip to disengage from the sealing groove, forming a precise venting channel. After venting is completed, the reset function of the movable spring ensures that the sealing plate drives the sealing strip to re-engage in the sealing groove, restoring the sealing state. Simultaneously, through the threaded connection design between the moving sleeve and the mating sleeve, combined with the limiting function of the guide groove and guide rail, the preload of the movable spring can be precisely adjusted, achieving continuous adjustment of the pressure relief threshold. This allows the equipment to adapt to precise pressure control for different tea varieties and processing requirements, significantly improving the consistency of tea flavor quality and the safety of equipment operation, providing key technical support for the large-scale production of high-quality tea.

[0020] 3. The clamping mechanism consists of a clamping sleeve, a push plate, a push rod, an adapter plate, a fixed block, a moving block, an adapter hole, an adapter groove, a moving spring, a clamping block, a clamping spring, and a clamping block. Through an innovative multi-stage locking and elastic support mechanical anti-loosening design, it completely solves the technical problems of easy displacement and poor stability after adjustment in traditional pressure relief devices. The rotational locking design of the adapter plate, adapter hole, and adapter groove, combined with the precise cooperation between the push rod and the push plate, constructs a highly reliable mechanical interlocking system. The sliding guide function of the clamping rail and clamping groove, plus the precise meshing of the clamping block, clamping wheel, and clamping block, forms a rigid locking mechanism. The overall structure is ingeniously designed and the locking mechanism is reliable. Through multiple redundant protections, it ensures the long-term stability after the pressure relief threshold is adjusted. Even under harsh conditions such as long-term operation of the equipment, frequent vibration, and gas impact, the adjusted pressure relief parameters can still be kept from deviating. This completely solves the threshold drift problem caused by insufficient stability of the adjustment mechanism in the existing technology, significantly improving the consistency of tea quality and the reliability of equipment use.

The pressure relief device includes a connecting pipe 2, a working sleeve 3, an output pipe 4, a fixing rod 5, a top block 6, a sealing plate 7, a movable sleeve 8, a mating sleeve 9, a fixing frame 10, and a movable spring 11.

A clamping mechanism is provided on the outside of the connecting pipe 2, and the clamping mechanism includes the clamping sleeve 1. 2. Push plate 13, push rod 14, adapter plate 15, fixing block 16, moving block 17, adapter hole 18, adapter groove 19, moving spring 20, clamping block 21, clamping spring 22 and clamping block 23. The clamping sleeve 12 is slidably installed on the outside of the connecting pipe 2. Two push plates 13 are fixedly installed on the push rod 14. The push rod 14 is fixedly installed on one side of the clamping sleeve 12. The adapter plate 15 is rotatably installed on the outside of the connecting pipe 2. The fixing block 16 is fixedly installed on the outside of the connecting pipe 2. The moving block 17 is fixedly installed on one side of the adapter plate 15. The adapter hole 18 is opened at one end of the adapter groove 19. The adapter groove 19 is opened on the adapter plate 15. Multiple clamping blocks 21 are movably arranged on one side of the use sleeve 3. The two ends of the clamping spring 22 are respectively connected to two adjacent clamping blocks 21. Multiple clamping blocks 23 are fixedly installed on the outside of the connecting pipe 2.

[0031] The stir-frying device includes a mounting bracket 24, a heating base 25, a driven wheel 26, a driving wheel 27, a motor 28, a pot body 29, and a stir-frying rack 30. The mounting bracket 24 is rotatably mounted on one side of the heating base 25. The driven wheel 26 is detachably connected to the top of the stir-frying rack 30. The driving wheel 27 meshes with the driven wheel 26 and is detachably connected to the output end of the motor 28. The pot body 29 is detachably mounted in the heating base 25, and the stir-frying rack 30 is rotatably mounted below the mounting bracket 24.

[0032] A handle 31 is detachably provided on one side of the pot body 29.

[0033] In this embodiment, when it is necessary to move the mounting bracket 24 to one side, causing the mounting bracket 24 to open the pot lid 1, tea leaves are added to the pot body 29. Then, the mounting bracket 24 causes the pot lid 1 to close back onto the pot body 29. The heating base 25 is then turned on to heat the pot body 29. The motor 28 is then turned on, causing the drive wheel 27 connected to the output end to rotate. The drive wheel 27 then drives the driven wheel 26 on one side to rotate, and the driven wheel 26 then drives the stir-frying rack 30 to rotate, thus stir-frying the tea leaves. When the internal pressure of the pot body 29 exceeds a set threshold, the gas pushes open the sealing plate 7, and the sealing plate 7 causes the sealing strip 34 on one side to detach from the sealing groove 35. The sealing plate 7 slides along the guide rail 42 and guide groove 43, and moves along the inner top block 6. Then, the sealing plate 7 and the moving sleeve 8 cooperate to squeeze the movable spring 11. The sealing plate 7 then moves to the outside of the fixed rod 5, whose diameter is significantly smaller than that of the top block 6. Then, the gas enters the connecting pipe 2, passes through the gap between the sealing plate 7 and the fixed rod 5, and then passes through the moving sleeve 8, and is finally discharged through the output pipe 4. When the pressure value is lower than the exhaust threshold, the movable spring 11 resets and drags the sealing plate 7, so that the density plate drives the sealing strip 34 to slide and reset along the guide rail 42 and guide groove 43. Then, the sealing plate 7 drives the sealing strip 34 to re-insert into the sealing groove 35, and a new sealing environment is formed.

[0034] Please see Figures 3-5 As a further embodiment of the overall equipment: a movable hole 32 is provided in the fixed block 16, and a movable rod 33 is connected to one side of the movable block 17, with one end of the movable rod 33 slidably inserted into the movable hole 32.

[0035] A sealing strip 34 is fixedly provided on one side of the sealing plate 7, and a sealing groove 35 is provided on one side of the fixing frame 10, and the sealing strip 34 is inserted into the sealing groove 35.

[0036] A push spring 36 is movably sleeved on the outside of the push rod 14. One end of the push spring 36 is connected to the clamping sleeve 12, and the other end of the push spring 36 is connected to the adapter plate 15 in contact. A limit groove 37 is opened on the outside of the connecting pipe 2. A limit block 38 is fixedly provided on the inside of the clamping sleeve 12. The limit block 38 slides in the limit groove 37.

[0037] The clamping block 21 has a clamping groove 39. The clamping rail 40 is fixed on one side of the sleeve 3. The clamping groove 39 is adapted to the clamping rail 40. The clamping wheel 41 is rotatably provided on one side of the clamping block 21. The clamping wheel 41 is engaged between the two clamping blocks 23.

[0038] A guide rail 42 is fixedly provided on the inner side of the connecting pipe 2, and a guide groove 43 is provided on the outer side of the movable sleeve 8 and the sealing plate 7. The guide groove 43 is adapted to the guide rail 42.

[0039] More specifically, when the exhaust threshold needs to be adjusted, firstly, the adapter plate 15 is rotated forward, causing the adapter hole 18 and adapter groove 19 to rotate forward. The adapter plate 15 also causes one side moving block 17 to rotate forward. Then, the moving block 17 causes one side moving rod 33 to rotate forward along the moving hole 32. The moving block 17 and the fixed block 16 cooperate to compress the moving spring 20. When the moving spring 20 is compressed to its limit, the adapter hole 18 rotates to a position concentric with the push plate 13. Then, the locking sleeve 12 is pushed, causing the inner limiting block 38 to slide along the limiting groove 37. The locking sleeve 12 also causes the push rod 14 and push plate 13 to slide through the adapter hole 18. The locking sleeve 12 then interacts with the adapter... Plate 15 compresses the push spring 36. When the push spring 36 is compressed to its limit, a push plate 13 near the clamping sleeve 12 slides through the adapter hole 18 and moves to the other side of the adapter plate 15. Then the adapter plate 15 is released, and the moving spring 20 pushes the moving block 17 to rotate in the opposite direction. The moving block 17 then drives the moving rod 33 to rotate in the opposite direction along the moving hole 32, and the moving block 17 also drives the adapter plate 15 to rotate in the opposite direction. The adapter plate 15 then drives the adapter hole 18 and the adapter groove 19 to rotate in the opposite direction, so that the push rod 14 enters the adapter groove 19. Then the push rod 14 and the push plate 13 near the clamping sleeve 12 cooperate to limit the clamping sleeve 12 to one side of the adapter plate 15, so that the clamping sleeve 12 no longer clamps the sleeve. The outer limit of the tension wheel 41 is then set, and the sleeve 3 is rotated in the forward direction, causing the sleeve 3 to drive the clamping rail 40 to rotate in the forward direction. Then, the clamping rail 40 and the clamping groove 39 cooperate to drive the clamping block 21 to rotate in the forward direction. Then, the clamping block 21 drives the clamping wheel 41 to roll out between the two clamping blocks 23. Then, the clamping wheel 41 will drive the clamping block 21 to slide outward along the clamping rail 40 and the clamping groove 39, and the clamping block 21 will drive the clamping spring 22 to stretch outward. At the same time, the sleeve 3 will drive the inner mating sleeve 9 to rotate in the forward direction. Since the inner wall of the mating sleeve 9 and the outer wall of the movable sleeve 8 are connected by threads, and the guide groove 43 and the guide rail 42 cooperate to limit the movable sleeve 8, the movable sleeve 8 will not rotate. Then, the movable sleeve 8 will move along the guide rail 43. 2. Slides with guide groove 43, then shortens the distance between moving sleeve 8 and sealing plate 7, causing movable spring 11 to be compressed to a certain extent. Then, the thrust applied by movable spring 11 to sealing plate 7 increases, so that one side of sealing plate 7 needs to withstand greater pressure to open. When it is necessary to make one side of sealing plate 7 withstand less pressure to open, after adjusting to the appropriate threshold, stop rotating sleeve 3. At the same time, the clamping rail 40 drives the clamping block 21 to rotate to the position corresponding to the two clamping blocks 23 through clamping groove 39. Then, the clamping spring resets and pulls the clamping block to slide inward along the clamping rail and clamping groove, so that the clamping block drives the clamping wheel to engage between the two corresponding clamping blocks 23. Then, rotate the adapter plate 15 forward again.The adapter plate 15 drives the adapter hole 18 and adapter groove 19 to rotate forward again, and the adapter plate 15 will drive the moving block 17 on one side to rotate forward again. Then the moving block 17 will drive the moving rod 33 on one side to rotate forward again along the moving hole 32. The moving block 17 will cooperate with the fixed block 16 again to press the moving spring 20. When the adapter hole 18 rotates to the position concentric with the push plate 13, the push spring 36 resets and pushes the locking block 38 to slide and reset along the limiting groove 37. The locking sleeve 12 will drive the two push plates 13 to slide and reset through the push rod 14. When the push spring 36 is fully reset, the push plate 13 at the top of the push rod 14 will move and reset to the original side of the adapter plate 15. Then the adapter plate 15 is released, and the moving spring... 20. Pushing the moving block 17 to rotate and reset, the moving block 17 will then drive the moving rod 33 on one side to rotate and reset along the moving hole 32. The moving block 17 will also drive the adapter hole 18 and adapter groove 19 to rotate and reset to positions not corresponding to the adapter rod and adapter plate 15 via the adapter plate 15. Then, the adapter rod and the top adapter plate 15 cooperate to support the clamping sleeve 12 on one side of the adapter plate 15. With the upper limit block 38 and the limiting groove 37 limiting the clamping sleeve 12, it will not move. The inner wall of the clamping sleeve 12 limits the outer wall of the clamping wheel 41, preventing the clamping wheel 41 and the clamping block 21 from sliding outwards. This achieves rotational limitation of the use sleeve 3, preventing accidental rotation and ensuring the stability of the adjusted structure.

[0040] In summary, during the use or operation of the entire equipment: when it is necessary to move the mounting bracket 24 to one side, causing the mounting bracket 24 to open the pot lid 1, then add tea leaves to the pot body 29, and then cause the mounting bracket 24 to move the pot lid 1 back onto the pot body 29. Then, turn on the heating base 25, which will heat the pot body 29. Then, turn on the motor 28, which will drive the drive wheel 27 connected to the output end to rotate. The drive wheel 27 will then drive the driven wheel 26 on one side to rotate, and the driven wheel 26 will then drive the stir-frying rack 30 to rotate, thus stir-frying the tea leaves. When the internal pressure value of the pot body 29 exceeds the set threshold, the gas will push open the sealing plate 7, and then the sealing plate 7 will drive the sealing strip 34 on one side out of the sealing groove 35. The sealing plate 7 detaches from the guide rail 42 and guide groove 43 and moves along the inner top block 6. Then, the sealing plate 7 and the moving sleeve 8 cooperate to squeeze the movable spring 11. The sealing plate 7 then moves to the outside of the fixed rod 5, whose diameter is significantly smaller than that of the top block 6. The gas then enters the connecting pipe 2, passes through the gap between the sealing plate 7 and the fixed rod 5, and then passes through the moving sleeve 8 and is finally discharged through the output pipe 4. When the pressure value is lower than the exhaust threshold, the movable spring 11 resets and drags the sealing plate 7, causing the density plate to drive the sealing strip 34 to slide and reset along the guide rail 42 and guide groove 43. Then, the sealing plate 7 drives the sealing strip 34 to re-enter the sealing groove 35, re-forming a sealed environment.

[0041] When the exhaust threshold needs to be adjusted, first rotate the adapter plate 15 clockwise, causing the adapter hole 18 and adapter groove 19 to rotate clockwise. The adapter plate 15 also causes one side moving block 17 to rotate clockwise. Then, the moving block 17 causes one side moving rod 33 to rotate clockwise along the moving hole 32. The moving block 17 and the fixed block 16 cooperate to compress the moving spring 20. When the moving spring 20 is compressed to its limit, the adapter hole 18 rotates to a position concentric with the push plate 13. Then, the locking sleeve 12 is pushed, causing the inner limiting block 38 to slide along the limiting groove 37. The locking sleeve 12 also causes the push rod 14 and push plate 13 to slide through the adapter hole 18. The locking sleeve 12 and the adapter plate 15... When the push spring 36 is compressed to its limit, a push plate 13 near the clamping sleeve 12 slides through the adapter hole 18 and moves to the other side of the adapter plate 15. Then the adapter plate 15 is released, and the moving spring 20 pushes the moving block 17 to rotate in the opposite direction. The moving block 17 then drives the moving rod 33 to rotate in the opposite direction along the moving hole 32, and the moving block 17 also drives the adapter plate 15 to rotate in the opposite direction. The adapter plate 15 then drives the adapter hole 18 and the adapter groove 19 to rotate in the opposite direction, so that the push rod 14 enters the adapter groove 19. Then the push rod 14 and the push plate 13 near the clamping sleeve 12 cooperate to limit the clamping sleeve 12 to one side of the adapter plate 15, so that the clamping sleeve 12 no longer clamps the clamping wheel. 41 is limited on the outside, and then the sleeve 3 is rotated in the forward direction, causing the sleeve 3 to drive the clamping rail 40 to rotate in the forward direction. Then the clamping rail 40 and the clamping groove 39 cooperate to drive the clamping block 21 to rotate in the forward direction. Then the clamping block 21 drives the clamping wheel 41 to roll out from between the two clamping blocks 23. Then the clamping wheel 41 will drive the clamping block 21 to slide outward along the clamping rail 40 and the clamping groove 39, and the clamping block 21 will drive the clamping spring 22 to stretch outward. At the same time, the sleeve 3 will drive the inner mating sleeve 9 to rotate in the forward direction. Since the inner wall of the mating sleeve 9 and the outer wall of the movable sleeve 8 are connected by threads, and the guide groove 43 and the guide rail 42 cooperate to limit the movable sleeve 8, the movable sleeve 8 will not rotate. Then the movable sleeve 8 will move along the guide rail 42. The sleeve 8 slides along the guide groove 43, and then the distance between the moving sleeve 8 and the sealing plate 7 shortens, causing the movable spring 11 to be compressed to a certain extent. The movable spring 11 then increases the thrust applied to the sealing plate 7, requiring one side of the sealing plate 7 to withstand greater pressure to open. Conversely, it requires less pressure on one side to open. Once the appropriate threshold is reached, the rotation of the sleeve 3 stops, and the clamping rail 40 drives the clamping block 21 to rotate to the position corresponding to the two clamping blocks 23 via the clamping groove 39. Then, the clamping spring resets, pulling the clamping block to slide inward along the clamping rail and clamping groove, causing the clamping block to drive the clamping wheel to engage between the two corresponding clamping blocks 23. Finally, the adapter plate 15 is rotated forward again.The adapter plate 15 drives the adapter hole 18 and adapter groove 19 to rotate forward again, and the adapter plate 15 will drive the moving block 17 on one side to rotate forward again. Then the moving block 17 will drive the moving rod 33 on one side to rotate forward again along the moving hole 32. The moving block 17 will cooperate with the fixed block 16 again to press the moving spring 20. When the adapter hole 18 rotates to the position concentric with the push plate 13, the push spring 36 resets and pushes the locking block 38 to slide and reset along the limiting groove 37. The locking sleeve 12 will drive the two push plates 13 to slide and reset through the push rod 14. When the push spring 36 is fully reset, the push plate 13 at the top of the push rod 14 will move and reset to the original side of the adapter plate 15. Then the adapter plate 15 is released, and the moving spring... 20. Pushing the moving block 17 to rotate and reset, the moving block 17 will then drive the moving rod 33 on one side to rotate and reset along the moving hole 32. The moving block 17 will also drive the adapter hole 18 and adapter groove 19 to rotate and reset to positions not corresponding to the adapter rod and adapter plate 15 via the adapter plate 15. Then, the adapter rod and the top adapter plate 15 cooperate to support the clamping sleeve 12 on one side of the adapter plate 15. With the upper limit block 38 and the limiting groove 37 limiting the clamping sleeve 12, it will not move. The inner wall of the clamping sleeve 12 limits the outer wall of the clamping wheel 41, preventing the clamping wheel 41 and the clamping block 21 from sliding outwards. This achieves rotational limitation of the use sleeve 3, preventing accidental rotation and ensuring the stability of the adjusted structure.
