Description

Technical Field

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

[0002] Tea processing is the entire process of using necessary techniques to turn freshly picked tea leaves into finished tea that can be consumed directly or used as an additive in food, medicine, and other products. According to different processing stages, tea processing can be divided into primary processing, refining processing, and reprocessing, and the resulting finished tea products are respectively called primary processed tea, refined tea, and reprocessed tea.

[0003] For example, CN223053819U discloses a fermentation device for tea production and processing, including a processing box. A motor is fixedly connected to the right side of the processing box, and a rotating rod is fixedly connected to the output end of the motor. A fermentation tank is provided on the inner wall of the processing box. A first bearing is fixedly embedded on the right side of the fermentation tank, and the inner ring of the first bearing is fixedly connected to the outer surface of the rotating rod. A second bearing is fixedly embedded on the inner wall of the fermentation tank, and the right end of the rotating rod is fixedly connected to the inner ring of the second bearing. This device heats the tea leaves in the fermentation tank by generating heat with an electric heater, and then pumps water to an atomizing nozzle. The atomizing nozzle sprays water onto the tea leaves, realizing the processing and fermentation of the tea leaves in the fermentation tank. The motor drives the rotating rod to rotate, which in turn drives the stirring rod to rotate, turning and stirring the tea leaves in the fermentation tank, so that the tea leaves are evenly heated and come into contact with water, achieving uniform fermentation of the tea leaves and improving the fermentation efficiency.

[0004] Stirring tea leaves with a single stirring rod can easily create dead zones, making it impossible to achieve uniform stirring. This results in uneven heating and moisture distribution during the fermentation process, with some tea leaves being over-fermented or under-fermented, affecting the overall quality and flavor of the finished tea. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fermentation device for tea processing, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fermentation device for tea processing, including a base, a fermentation tank fixedly connected to the top of the base, a water inlet pipe provided inside the fermentation tank extending outward, a stirring mechanism provided inside the fermentation tank, the stirring mechanism including a motor, the motor fixedly connected to the side of the fermentation tank, the output end of the motor fixedly connected to a rotating shaft via a coupling, the rotating shaft movably penetrating through the fermentation tank and extending inward therein, a rectangular sleeve movably fitted on the outer wall of the rotating shaft, a first abutting rod fixedly connected to the outer wall of the rectangular sleeve, an abutting ball fixedly connected to the inner wall of the fermentation tank, the abutting ball contacting the first abutting rod, a stirring plate fixedly connected to the outer wall of the rectangular sleeve, and a first spring movably fitted on the outer wall of the rotating shaft. Firstly, an appropriate amount of water is injected into the fermentation tank through the water inlet pipe. Clean water and an electric heater start working, heating the water and air in the fermentation tank to provide the appropriate temperature for fermentation. When the temperature reaches the set value, the water pump starts, delivering water through pipes to the atomizing nozzle. The atomizing nozzle sprays water evenly onto the tea surface in the form of a fine mist. Then, the motor starts, driving the rotating shaft to rotate via a coupling. The rotating shaft drives the rectangular sleeve and the first contact rod and stirring plate fixed on it to move in a circular motion. During the rotation, the first contact rod periodically contacts the contact ball fixed to the inner wall of the fermentation tank, generating an axial thrust. This thrust causes the rectangular sleeve to move axially along the rotating shaft and compress the first spring. When the first contact rod passes the contact ball, the rectangular sleeve moves in the opposite direction under the restoring force of the first spring. The above process causes the stirring plate to generate axial reciprocating motion while rotating, realizing the basic stirring and turning of the tea.

[0007] Preferably, a movable plate is slidably connected inside the stirring plate, and stirring rods are fixedly connected to the left and right sides of the movable plate, respectively. A second spring is directly fixedly connected to the inner wall of the stirring plate.

[0008] Preferably, a first abutment plate is fixedly connected to the top of the movable plate, and several protrusions are fixedly connected to the bottom inner wall of the fermentation tank. The first abutment plate contacts the protrusions. When the stirring plate rotates, the movable plate connected to it by a second spring moves accordingly. The first abutment plate fixed to the top of the movable plate periodically contacts the several protrusions on the bottom inner wall of the fermentation tank. When in contact, the first abutment plate is lifted, causing the movable plate to compress the second spring and move upward. When the movable plate moves upward, it causes the stirring rods on both sides to lift. After passing the protrusions, under the restoring force of the second spring, the movable plate and stirring rods fall rapidly. The above-mentioned periodic lifting and falling action not only enhances the stirring effect but also prevents tea leaves from settling at the bottom of the tank.

[0009] Preferably, the fermenter is provided with a shaking mechanism, which includes a shaking plate that moves through the fermenter and extends into it. A connecting plate is fixedly connected to the right side of the shaking plate.

[0010] Preferably, a contact block is fixedly connected to the bottom of the connecting plate, a second contact rod is fixedly connected to the right side of the rotating shaft, and a third spring is fixedly connected between the connecting plate and the fermentation tank. When the rotating shaft rotates, the second contact rod fixedly connected to its right end rotates accordingly. The second contact rod periodically pushes the contact block at the bottom of the connecting plate, and the connecting plate drives the shaking plate to move upward and compress the third spring. When the second contact rod passes the contact block, the shaking plate resets under the elastic action of the third spring. The movement of the shaking plate also causes the tea leaves to shake up and down, further improving the loosening effect of the tea leaves.

[0011] Preferably, the shaking plate has an air bladder inside, and the top of the air bladder has several air blowing pipes. The shaking plate is sleeved on the outer wall of the air blowing pipes. A placement plate is fixedly connected to the top of the base. The placement plate is in contact with the air bladder. Initially, the air bladder is compressed. When the shaking plate moves upward, the air bladder begins to release. When the shaking plate returns to its original position and moves downward, it begins to compress the air bladder. When the air bladder is compressed, the internal air is blown onto the surface of the tea leaves through the air blowing pipes, which enhances ventilation and humidity regulation, prevents the tea leaves from compacting and clumping, increases the contact area between the tea leaves and the air, and promotes the oxidation reaction during the fermentation process.

[0012] Preferably, the fermentation tank is equipped with an anti-deviation mechanism, which includes a movable rod that extends through the fermentation tank and into it. A push plate is fixedly connected to one side of the movable rod. A telescopic plate is provided inside the push plate and contacts a shaking plate. The telescopic plate is provided to avoid motion interference between the shaking plate and the push plate when the shaking plate moves up and down. A fourth spring is movably sleeved on the outer wall of the movable rod. A shaking plate is slidably connected to the right side of the push plate. A limit spring is directly provided between the shaking plate and the push plate. A ring is fixedly connected to the top of the push plate. A fixed rod is fixedly connected to the outer wall of the first abutment rod. The ring is sleeved on the outer wall of the fixed rod. When the first abutment rod rotates and moves left and right, it will drive the fixed rod to move left and right, thereby forcing the push plate and the shaking plate on its side to move left and right. When the push plate moves, it pushes the tea leaves that have deviated from the periphery to the center.

[0013] Preferably, a corrugated plate is fixedly connected to the inner wall of the fermentation tank, and through holes are opened inside the push plate and the shaking plate. The through holes are fitted onto the outer wall of the corrugated plate, and a second abutment plate is fixedly connected to the top of the shaking plate. The second abutment plate contacts the corrugated plate. When the shaking plate moves left and right, the second abutment plate at its top contacts the corrugated plate and generates up and down shaking, which effectively breaks up the accumulation of tea leaves near the tank wall and ensures that the tea leaves are evenly distributed in the fermentation tank.

[0014] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0015] 1. This fermentation device for tea processing drives a rectangular sleeve and a stirring plate to rotate via a rotating shaft. Simultaneously, the interaction between the first contact rod and the contact ball causes the stirring plate to generate axial displacement during rotation, thereby breaking up the stirring dead zones, increasing the stirring range, and ensuring that the tea leaves are fully turned over. Furthermore, the moving plate is extendable under the action of a second spring, which, together with the contact between the first contact plate and the protrusion, enables the stirring rod to move up and down periodically, further enhancing the uniformity and adaptability of the stirring, thereby achieving more comprehensive temperature and humidity contact, improving fermentation consistency and finished product quality.

[0016] 2. This fermentation device for tea processing periodically pushes the connecting plate with the second abutment rod on the rotating shaft, causing the shaking plate to move up and down, keeping the tea leaves loose during fermentation and preventing clumping. In addition, the air bag is compressed during shaking to generate airflow, which blows air onto the surface of the tea leaves through the air blowing pipe, promoting air circulation and uniform humidity distribution, and further improving the fermentation quality.

[0017] 3. This fermentation device for tea processing uses a pusher plate and a shaking plate to move back and forth periodically under the action of a wave plate. This breaks up the accumulation of tea leaves near the tank wall, ensuring the overall fluidity of the tea leaves and the uniformity of fermentation. The shaking plate also generates an up-and-down shaking motion while moving horizontally, effectively breaking up the stickiness between the tea leaves. The up-and-down shaking causes the tea layer to undulate periodically, preventing the tea leaves from being compacted and clumped together, increasing the contact area between the tea leaves and the air, and promoting the oxidation reaction during the fermentation process.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8One embodiment of the present invention is: a fermentation device for tea processing, including a base 1, a fermentation tank 2 fixedly connected to the top of the base 1, a water inlet pipe 3 provided inside the fermentation tank 2 extending outward, a stirring mechanism 4 provided inside the fermentation tank 2, the stirring mechanism 4 including a motor 411, the motor 411 fixedly connected to the side of the fermentation tank 2, the output end of the motor 411 fixedly connected to a rotating shaft 412 via a coupling, the rotating shaft 412 movably passing through the fermentation tank 2 and extending inward therein, a rectangular sleeve 413 movably fitted on the outer wall of the rotating shaft 412, a first abutment rod 414 fixedly connected to the outer wall of the rectangular sleeve 413, an abutment ball 415 fixedly connected to the inner wall of the fermentation tank 2, the abutment ball 415 contacting the first abutment rod 414, and the rectangular sleeve 413... A stirring plate 417 is fixedly connected to the outer wall, and a first spring 416 is movably sleeved on the outer wall of the rotating shaft 412. First, an appropriate amount of clean water is injected into the fermentation tank 2 through the water inlet pipe 3. The electric heater starts working to heat the water and air in the fermentation tank 2, providing the appropriate temperature for fermentation. When the temperature reaches the set value, the water pump starts and delivers water through the pipe to the atomizing nozzle. The atomizing nozzle sprays water evenly on the surface of the tea leaves in the form of a fine mist. Then, the motor 411 is started. After the motor 411 starts, it drives the rotating shaft 412 to rotate through the coupling. The rotating shaft 412 drives the rectangular sleeve 413 and the first contact rod 414 and the stirring plate 417 fixed on it to perform circular motion. During the rotation, the first contact rod 414 contacts the inner wall of the fermentation tank 2. The ball 415 makes periodic contact, generating an axial thrust. This thrust causes the rectangular sleeve 413 to move axially along the rotating shaft 412 and compress the first spring 416. When the first abutting rod 414 passes the abutting ball 415, the rectangular sleeve 413 moves in the opposite direction under the restoring force of the first spring 416. This process causes the stirring plate 417 to generate axial reciprocating motion while rotating, achieving basic stirring and turning of the tea leaves. A movable plate 418 is slidably connected inside the stirring plate 417. Stirring rods 419 are fixedly connected to the left and right sides of the movable plate 418, respectively. A second spring 421 is directly fixedly connected to the inner wall of the moving plate 418 and the inner wall of the stirring plate 417. A first abutting plate 420 is fixedly connected to the top of the moving plate 418. The bottom inner wall of the fermentation tank 2 is fixedly connected to... A plurality of protrusions 422 are attached. The first contact plate 420 contacts the protrusions 422. When the stirring plate 417 rotates, the moving plate 418 connected inside by the second spring 421 moves accordingly. The first contact plate 420 fixed to the top of the moving plate 418 periodically contacts the plurality of protrusions 422 on the bottom inner wall of the fermentation tank 2. When in contact, the first contact plate 420 is lifted, which drives the moving plate 418 to compress the second spring 421 and move upward. When the moving plate 418 moves upward, it drives the stirring rods 419 on both sides to lift. After passing the protrusions 422, under the restoring force of the second spring 421, the moving plate 418 and the stirring rods 419 fall rapidly. The above periodic lifting and falling action not only enhances the stirring effect, but also prevents tea leaves from settling at the bottom of the tank.

[0029] Working principle: First, an appropriate amount of clean water is injected into the fermentation tank 2 through the water inlet pipe 3. The electric heater starts working to heat the water and air in the fermentation tank 2, providing the appropriate temperature for fermentation. When the temperature reaches the set value, the water pump starts and delivers the water through the pipe to the atomizing nozzle. The atomizing nozzle sprays the water evenly onto the surface of the tea leaves in the form of a fine mist. Then, the motor 411 is started. After the motor 411 starts, it drives the rotating shaft 412 to rotate through the coupling. The rotating shaft 412 drives the rectangular sleeve 413 and the first abutment rod 4 fixed on it. 14 and the stirring plate 417 make circular motion. During the rotation, the first contact rod 414 periodically contacts the contact ball 415 fixed to the inner wall of the fermentation tank 2, generating an axial thrust. This thrust causes the rectangular sleeve 413 to move axially along the rotating shaft 412 and compress the first spring 416. When the first contact rod 414 passes the contact ball 415, under the action of the restoring force of the first spring 416, the rectangular sleeve 413 moves in the opposite direction. The above process causes the stirring plate 417 to generate axial reciprocating motion while rotating, realizing the basic stirring and turning of the tea leaves.

[0030] When the stirring plate 417 rotates, the movable plate 418 connected inside it by the second spring 421 moves accordingly. The first contact plate 420 fixed to the top of the movable plate 418 periodically contacts several protrusions 422 on the inner wall of the bottom of the fermentation tank 2. When they contact, the first contact plate 420 is lifted, which causes the movable plate 418 to compress the second spring 421 and move upward. When the movable plate 418 moves upward, it causes the stirring rods 419 on both sides to lift. After passing the protrusions 422, under the restoring force of the second spring 421, the movable plate 418 and the stirring rods 419 fall quickly. The above periodic lifting and falling action not only enhances the stirring effect, but also prevents tea leaves from settling at the bottom of the tank.

[0031] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, a shaking mechanism 5 is provided inside the fermentation tank 2. The shaking mechanism 5 includes a shaking plate 511, which movably passes through the fermentation tank 2 and extends into it. A connecting plate 512 is fixedly connected to the right side of the shaking plate 511, and an abutment block 513 is fixedly connected to the bottom of the connecting plate 512. A second abutment rod 514 is fixedly connected to the right side of the rotating shaft 412. A third spring 515 is fixedly connected between the connecting plate 512 and the fermentation tank 2. When the rotating shaft 412 rotates, the second abutment rod 514 fixedly connected to its right end rotates accordingly. The second abutment rod 514 periodically pushes the abutment block 513 at the bottom of the connecting plate 512. The connecting plate 512 drives the shaking plate 511 to move upward and compress the third spring 515. When the second abutment rod 514 passes the abutment block 513, the shaking plate 511... The third spring 515 is reset under its elastic action. The movement of the shaking plate 511 causes the tea leaves to shake up and down, further improving the loosening effect of the tea leaves. An air bladder 516 is set inside the shaking plate 511. Several air blowing pipes 517 are set on the top of the air bladder 516. The shaking plate 511 is sleeved on the outer wall of the air blowing pipes 517. A placement plate 518 is fixedly connected to the top of the base 1. The placement plate 518 is in contact with the air bladder 516. In the initial state, the air bladder 516 is in a compressed state. When the shaking plate 511 moves upward, the air bladder 516 begins to release. When the shaking plate 511 resets and moves downward, it begins to squeeze the air bladder 516. When the air bladder 516 is compressed, the internal air is blown to the surface of the tea leaves through the air blowing pipes 517, which enhances ventilation and humidity regulation, prevents the tea leaves from being compacted and clumped, increases the contact area between the tea leaves and the air, and promotes the oxidation reaction during the fermentation process.

[0032] Working principle: When the rotating shaft 412 rotates, the second abutment rod 514 fixedly connected to its right end rotates accordingly. The second abutment rod 514 periodically pushes the abutment block 513 at the bottom of the connecting plate 512. The connecting plate 512 drives the shaking plate 511 to move upward and compress the third spring 515. When the second abutment rod 514 passes the abutment block 513, the shaking plate 511 resets under the elastic action of the third spring 515. The movement of the shaking plate 511 also causes the tea leaves to shake up and down, further improving the loosening effect of the tea leaves.

[0033] Initially, the air bladder 516 is compressed. When the shaking plate 511 moves upward, the air bladder 516 begins to release. When the shaking plate 511 returns to its original position and moves downward, it begins to compress the air bladder 516. When the air bladder 516 is compressed, the internal air is blown onto the surface of the tea leaves through the air blowing pipe 517, which enhances ventilation and humidity regulation, prevents the tea leaves from being compacted and clumped together, increases the contact area between the tea leaves and the air, and promotes the oxidation reaction during the fermentation process.

[0034] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, the fermentation tank 2 is provided with an anti-deviation mechanism 6. The anti-deviation mechanism 6 includes a movable rod 611, which movably passes through the fermentation tank 2 and extends into it. A push plate 613 is fixedly connected to one side of the movable rod 611. A telescopic plate is provided inside the push plate 613 and contacts the shaking plate 511. The telescopic plate is provided to avoid motion interference between the shaking plate 511 and the push plate 613 when the shaking plate 511 moves up and down. A fourth spring 612 is movably sleeved on the outer wall of the movable rod 611. A shaking plate 614 is slidably connected to the right side of the push plate 613. A limit spring is directly provided between the shaking plate 614 and the push plate 613. A ring 615 is fixedly connected to the top of the push plate 613. A fixing rod 616 is fixedly connected to the outer wall of the first abutment rod 414. The first contact rod 414, which is fitted onto the outer wall of the fixed rod 616, rotates and moves left and right, thereby causing the fixed rod 616 to move left and right. This forces the push plate 613 and its side shaking plate 614 to move left and right. When the push plate 613 moves, it pushes the tea leaves that have drifted off to the side to the center. A corrugated plate 617 is fixedly connected to the inner wall of the fermentation tank 2. The push plate 613 and the shaking plate 614 have through holes inside, which are fitted onto the outer wall of the corrugated plate 617. A second contact plate 618 is fixedly connected to the top of the shaking plate 614. The second contact plate 618 contacts the corrugated plate 617. When the shaking plate 614 moves left and right, the second contact plate 618 at its top contacts the corrugated plate 617, causing it to shake up and down. This effectively breaks up the accumulation of tea leaves near the tank wall and ensures that the tea leaves are evenly distributed in the fermentation tank 2.

[0035] Working principle: When the first contact rod 414 rotates and moves left and right, it will drive the fixed rod 616 to move left and right, thereby forcing the push plate 613 and its side shaking plate 614 to move left and right. When the push plate 613 moves, it pushes the tea leaves that have deviated from the side to the center, breaking the accumulation of tea leaves near the can wall, and ensuring the overall fluidity and uniform fermentation of the tea leaves.

[0036] When the shaking plate 614 moves left and right, the second contact plate 618 at its top comes into contact with the wave plate 617 and shakes up and down, effectively breaking up the tea leaves piled up near the tank wall and ensuring that the tea leaves are evenly distributed in the fermentation tank 2.

[0037] This invention provides a fermentation apparatus for tea processing. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
