Description

Technical Field

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

[0002] Heap fermentation, or "wodui," is a crucial fermentation process in the production of ripe Pu-erh tea and a key factor in determining its quality. It involves piling the tea leaves to a certain height, sprinkling them with water, and covering them with burlap to promote fermentation. Once the tea has transformed to a certain degree, it is spread out to dry. After heap fermentation, the color of the tea changes from green to yellow, chestnut red, and chestnut black, depending on the degree of fermentation, and it is academically classified as dark tea.

[0003] According to Chinese Patent Publication No. CN217407660U, a tea processing fermentation device includes a vertical plate. One end of a rectangular plate is fixedly connected to the upper part of one side of the vertical plate. A motor is fixedly connected to the upper end of the rectangular plate. The output shaft of the motor is fixedly connected to the center of a first pulley. The center of the first pulley is fixedly connected to the center of a first gear. The first gear meshes with a second gear. The central shaft of the second gear passes through and is movably connected to the upper middle part of the vertical plate. This utility model relates to the field of tea processing equipment, specifically to a tea processing fermentation device. This utility model is a tea processing fermentation device that facilitates the processing and fermentation of tea leaves.

[0004] Although the aforementioned fermentation device increases the contact speed between tea leaves and steam by rotating the fermentation tank and the stirring rod in opposite directions, the stirring rod's position for stirring and turning the tea leaves is fixed and cannot be changed during the stirring process. This limits the range of tea leaf turning and also prevents the tea leaves from being kneaded while being stirred and turned. Consequently, the tea leaves can only rely on simple mixing for fermentation, resulting in a single function and affecting the efficiency of tea fermentation. Therefore, a tea processing fermentation device is proposed to solve the above-mentioned problems. Summary of the Invention

A fixed seat is fixedly connected to the inner rod. A stirring blade is hinged to the fixed seat via a pin. A hinge ring is fixedly installed on the rotating shaft. A pull rod is hinged to the hinge ring via a pin. The other end of the pull rod is hinged to the stirring blade via a pin. An end cap is fixedly installed on the support frame, and a second hemisphere is fixedly connected to the inner wall of the end cap. The kneading mechanism includes a fixed plate and a triangular block. A guide post is slidably connected to the fixed plate. A ball head is fixedly installed at the upper end of the guide post. A second spring is sleeved on the guide post. A connecting post is fixedly connected to the lower end of the guide post. A pressure plate is fixedly connected to the lower end of the connecting post. The triangular block is fixedly connected to the rotating shaft.

[0007] Preferably, the rotating shaft is rotatably connected to the support frame via a bearing, and a limiting guide is provided on the rotating shaft, with the fixed seat passing through the interior of the limiting guide.

[0008] Preferably, the fixing plate is fixedly installed on the support frame, the fixing plate has a guide hole, the guide post passes through the interior of the guide hole, the second spring abuts against the bottom of the ball head, and the lower end of the second spring abuts against the fixing plate.

[0009] Preferably, a dual-shaft motor is fixedly installed on the support frame, a gear is fixedly installed on the right output end of the dual-shaft motor, and a gear ring is fixedly installed on the outer wall of the fermentation tank, with the gear meshing with the gear ring.

[0010] Preferably, a first synchronous pulley is fixedly installed on the left output end of the dual-axis motor, a synchronous belt is driven to the first synchronous pulley, and a second synchronous pulley is driven to the other end of the synchronous belt. The second synchronous pulley is fixedly installed on the rotating shaft.

[0011] Preferably, the outer wall of the fermentation tank has a material inlet, and a tank cover is fixedly installed inside the material inlet, with the turntable located inside the end cover.

[0012] Preferably, the steam spraying mechanism includes a fixed frame and a delivery pipe, wherein the fixed frame is fixedly installed on a support frame, and the delivery pipe is slidably connected to the fixed frame.

[0013] Preferably, a baffle is fixedly installed on the conveying pipe, a third spring is sleeved on the conveying pipe, and a connecting pipe is fixedly connected to the conveying pipe.

[0014] Preferably, one end of the third spring abuts against the baffle, and the other end of the third spring abuts against the fixed frame. The fixed frame has a square hole, and the conveying pipe passes through the interior of the square hole.

[0015] Preferably, a nozzle is fixedly installed on the delivery pipe, and a pusher is fixedly installed on the delivery pipe, with one end of the pusher extending through the right wall of the support frame into the end cap.

[0016] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This tea processing and fermentation device uses a dual-shaft motor to drive the fermentation tank and shaft to rotate. The shaft and the fermentation tank rotate in opposite directions. Inside the fermentation tank, stirring blades agitate the tea leaves, dispersing them. As the shaft rotates, the turntable on the inner rod rotates. When the first hemisphere on the turntable contacts the second hemisphere on the end cap, it pushes the inner rod to the left. This movement causes the stirring blades to move to the left. The stirring blades, pulled by the tie rod, deflect, increasing the stirring range. When the first and second hemispheres are misaligned, the inner rod resets under the action of a first spring. After resetting, the stirring blades are vertical. By moving the stirring blades, further stirring is achieved, and then changing their position to move the tea leaves further enhances the stirring effect. This avoids the problem of fixed, unadjustable stirring blades and dead zones in tea leaf agitation.

[0017] 2. This tea processing and fermentation device, through the rotation of the shaft, causes the triangular block on the shaft to rotate, and its corners to contact the ball head, pressing the ball head downwards. At this time, the connecting column pushes the pressure plate downwards, pressing the tea under the pressure plate against the wall of the fermentation tank. As the fermentation tank rotates, the tea under the pressure plate is kneaded. During the kneading process, endophytic bacteria of the tea are released into the leaf surface and the environment. These microorganisms re-adhere to the tea during the fermentation process, and decompose the macromolecules in the tea by secreting extracellular enzymes, accelerating the fermentation process. When the triangular block and the ball head are misaligned, the pressure plate is lifted and reset by the action of the second spring. With the rotation of the shaft, the pressure plate can repeatedly knead the tea, improving the efficiency of tea fermentation.

[0018] 3. This tea processing and fermentation device connects to an external steam generator via a connecting pipe, allowing its nozzles to spray steam onto the tea leaves inside the fermentation tank. When the turntable moves to the left, it contacts the pusher and pushes the pusher to the left, thereby moving the conveying pipe to the left to adjust the nozzle position. When the turntable moves to the right, the connecting pipe moves to the right under the action of a third spring to reset, allowing the nozzle position to be automatically adjusted. This avoids dead zones in steam spraying, preventing uneven moisture absorption of the tea leaves and further improving the fermentation effect.

[0019] 4. This tea processing and fermentation device involves spraying steam onto the tea leaves through a steam spraying mechanism, followed by kneading by a kneading mechanism. This allows the steam falling on the tea leaves to penetrate into the tea leaves as quickly as possible, providing the necessary moisture for fermentation. This effectively catalyzes the oxidation and decomposition reactions of the substances within the tea leaves, further accelerating fermentation. Improving steam penetration efficiency makes the humidity distribution within the tea pile more uniform, avoiding problems of excessively high or low humidity in certain areas. This contributes to the uniformity of tea fermentation, ensuring consistent fermentation results throughout the entire tea pile. Attached Figure Description

[0022] 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.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0026] Please see Figure 1-10 One embodiment of the present invention is: a tea processing fermentation device, including a support frame 1, a fermentation barrel 5 rotatably connected to the support frame 1 via bearings, a turning mechanism 2, a kneading mechanism 3, and a steam spraying mechanism 4. The flipping mechanism 2 includes a rotating shaft 201 and an inner rod 202. The inner rod 202 is located inside the rotating shaft 201. A first spring 204 is sleeved on one end of the inner rod 202, and a turntable 203 is fixedly installed on the other end of the inner rod 202. A first hemisphere 210 is fixedly connected to the turntable 203. A fixed seat 206 is fixedly connected to the inner rod 202. A stirring blade 207 is hinged to the fixed seat 206 by a pin. A hinge ring 208 is fixedly installed on the rotating shaft 201. A pull rod 209 is hinged to a pin, and the other end of the pull rod 209 is hinged to a stirring blade 207 via a pin. An end cover 211 is fixedly installed on the support frame 1, and a second hemisphere 212 is fixedly connected to the inner wall of the end cover 211. By starting the dual-shaft motor 7, the fermentation tank 5 and the rotating shaft 201 are driven to rotate. The rotating shaft 201 and the fermentation tank 5 rotate in opposite directions. At this time, the stirring blade 207 inside the fermentation tank 5 will stir the tea leaves, causing them to be dispersed. During the rotation of 201, when the turntable 203 on the inner rod 202 rotates, the first hemisphere 210 on the turntable 203 contacts the second hemisphere 212 on the end cover 211, which pushes the inner rod 202 towards the left end of the rotating shaft 201. At this time, the inner rod 202 will drive the stirring blade 207 to move to the left during the movement. Under the pull of the pull rod 209, the stirring blade 207 will bend, thereby increasing the stirring range of the stirring blade 207. When the first hemisphere 210 and the second hemisphere 212 are misaligned, the inner rod 202 will be reset under the action of the first spring 204. After the inner rod 202 is reset, the stirring blade 207 is in a vertical state. Based on the stirring, the stirring blade 207 is moved to promote stirring. Then the stirring blade 207 changes state to move the tea leaves, further promoting the stirring effect. This avoids the problem of the stirring blade 207 being fixed in position and unable to be adjusted, which would result in dead corners for tea leaf stirring. The kneading mechanism 3 includes a fixed plate 301 and a triangular block 307. A guide post 303 is slidably connected to the fixed plate 301. A ball head 304 is fixedly installed on the upper end of the guide post 303. A second spring 305 is sleeved on the guide post 303. A connecting post 302 is fixedly connected to the lower end of the guide post 303. A pressure plate 306 is fixedly connected to the lower end of the connecting post 302. The triangular block 307 is fixedly connected to the rotating shaft 201. When the rotating shaft 201 rotates, the corner of the triangular block 307 will contact the ball head 304 and press the ball head 304 downward. At this time, the connecting post 302 will push the pressure plate 306 downward. The moving plate 306 presses the tea leaves against the wall of the fermentation tank 5. As the fermentation tank 5 rotates, the tea leaves pressed against the plate 306 are kneaded. During the kneading process, endophytic bacteria in the tea leaves are released onto the leaf surface and into the environment. These microorganisms re-adhere to the tea leaves during the fermentation process and decompose macromolecules in the tea leaves by secreting extracellular enzymes, thus accelerating the fermentation process. When the triangular block 307 is misaligned with the ball head 304, the plate 306 is lifted and reset by the action of the second spring 305. As the rotating shaft 201 rotates, the plate 306 can repeatedly knead the tea leaves, improving the efficiency of the tea fermentation process.

[0027] The rotating shaft 201 is rotatably connected to the support frame 1 via a bearing. A limiting guide 205 is provided on the rotating shaft 201. The fixed seat 206 passes through the interior of the limiting guide 205. The limiting guide 205 allows the inner rod 202 to move when it moves, thereby driving the fixed seat 206 to move. The limiting guide 205 can limit the moving distance of the fixed seat 206.

[0028] The fixing plate 301 is fixedly installed on the support frame 1. The fixing plate 301 has a guide hole, and the guide post 303 passes through the inside of the guide hole. The second spring 305 abuts against the bottom of the ball head 304, and the lower end of the second spring 305 abuts against the fixing plate 301. The guide hole allows the guide post 303 to pass through the fixing plate 301, and the second spring 305 facilitates the reciprocating up and down movement of the pressure plate 306.

[0029] A dual-shaft motor 7 is fixedly installed on the support frame 1. A gear 9 is fixedly installed on the right output end of the dual-shaft motor 7. A gear ring 8 is fixedly installed on the outer wall of the fermentation barrel 5. The gear 9 meshes with the gear ring 8. By starting the dual-shaft motor 7, the gear 9 can be driven to rotate, thereby driving the gear ring 8 to rotate the fermentation barrel 5. The rotation of the fermentation barrel 5 facilitates the tumbling of the tea leaves inside the fermentation barrel 5.

[0030] A first synchronous pulley 10 is fixedly installed on the left output end of the dual-shaft motor 7. A synchronous belt 12 is driven to the first synchronous pulley 10. A second synchronous pulley 11 is driven to the other end of the synchronous belt 12. The second synchronous pulley 11 is fixedly installed on the rotating shaft 201. The arrangement of the synchronous pulley and the synchronous belt 12 enables the dual-shaft motor 7 to drive the rotating shaft 201 to rotate after starting. The rotation direction of the rotating shaft 201 is opposite to the rotation direction of the fermentation tank 5.

[0031] The outer wall of the fermentation barrel 5 has a material inlet, and a barrel cover 6 is fixedly installed inside the material inlet. The turntable 203 is located inside the end cover 211. The setting of the material inlet and the barrel cover 6 makes it convenient to put tea into or take out tea leaves from the fermentation barrel 5.

[0032] Working principle: The dual-shaft motor 7 drives the fermentation tank 5 and the rotating shaft 201 to rotate. The rotating shaft 201 and the fermentation tank 5 rotate in opposite directions. At this time, the stirring blades 207 inside the fermentation tank 5 will stir the tea leaves, dispersing them. During the rotation of the rotating shaft 201, when the turntable 203 on the inner rod 202 rotates, the first hemisphere 210 on the turntable 203 contacts the second hemisphere 212 on the end cover 211, pushing the inner rod 202 towards the left end of the rotating shaft 201. During its movement, the inner rod 202 causes the stirring blade 207 to move to the left. Under the pull of the tie rod 209, the stirring blade 207 may deflect, thereby increasing its stirring range. When the first hemisphere 210 and the second hemisphere 212 are misaligned, the inner rod 202 will reset under the action of the first spring 204. After resetting, the stirring blade 207 is in a vertical position. Based on the achieved stirring, moving the stirring blade 207 further promotes stirring. 07. The stirring area is further adjusted by changing the position of the stirring blade 207 to promote a more effective stirring process. This avoids the problem of dead zones in the stirring area caused by the fixed position of the stirring blade 207. During the rotation of the shaft 201, the triangular block 307 on the shaft rotates, and its corner contacts the ball head 304, pressing the ball head 304 downwards. At this time, the connecting column 302 pushes the pressure plate 306 downwards, pressing the tea leaves below the pressure plate 306 against the wall of the fermentation tank 5. As the fermentation tank 5 rotates, the pressure plate... The tea leaves pressed under 306 are kneaded. During the kneading process, the endophytic bacteria of the tea leaves are released onto the leaf surface and into the environment. These microorganisms re-adhere to the tea leaves during the fermentation process and decompose the macromolecules in the tea leaves by secreting extracellular enzymes, thus accelerating the fermentation process. When the triangular block 307 is misaligned with the ball head 304, its pressing plate 306 is lifted and reset under the action of the second spring 305. As the rotating shaft 201 rotates, its pressing plate 306 can knead the tea leaves repeatedly, improving the efficiency of the tea fermentation process.

[0033] Please see Figure 1-10 Based on the above embodiments, in another embodiment of the present invention, the steam spraying mechanism 4 includes a fixed frame 401 and a conveying pipe 402. The fixed frame 401 is fixedly installed on the support frame 1, and the conveying pipe 402 is slidably connected to the fixed frame 401. The steam spraying mechanism 4 is designed to facilitate the introduction of steam into the interior of the fermentation tank 5, thereby moistening the tea leaves.

[0034] A baffle 403 is fixedly installed on the conveying pipe 402, a third spring 404 is sleeved on the conveying pipe 402, and a connecting pipe 405 is fixedly connected to the conveying pipe 402. The connecting pipe 405 is configured to connect to an external steam generator. The third spring 404 allows the conveying pipe 402 to move back and forth, thereby adjusting the position of the nozzle 406 and avoiding the problem of dead zones in steam spraying.

[0035] One end of the third spring 404 abuts against the baffle 403 and the other end of the third spring 404 abuts against the fixed frame 401. The fixed frame 401 has a square hole, and the conveying pipe 402 passes through the inside of the square hole. The baffle 403 facilitates the transmission of the force of the third spring 404 to the conveying pipe 402, thereby allowing the conveying pipe 402 to be reset.

[0036] A nozzle 406 is fixedly installed on the conveying pipe 402, and a pusher 407 is fixedly installed on the conveying pipe 402. One end of the pusher 407 extends through the right wall of the support frame 1 into the end cover 211. When the turntable 203 moves to the left, the conveying pipe 402 can be pushed to the left by pushing the pusher 407.

[0037] Working principle: By connecting the connecting pipe 405 to an external steam generator, the nozzle 406 sprays steam onto the tea leaves inside the fermentation tank 5. When the turntable 203 moves to the left, it contacts the pusher 407, pushing the pusher 407 to the left, thereby moving the conveying pipe 402 to the left, achieving the purpose of adjusting the position of the nozzle 406. When the turntable 203 moves to the right, the connecting pipe 405 moves to the right under the action of the third spring 404 to reset, so that the position of the nozzle 406 can be automatically adjusted to avoid dead zones in steam spraying. The uneven moisture distribution of tea leaves further enhances the fermentation effect. After the tea leaves are sprayed with steam by the steam spraying mechanism 4, they are kneaded by the kneading mechanism 3. This allows the steam falling on the tea leaves to penetrate into the tea leaves as quickly as possible, providing the necessary fermentation moisture. This can more effectively catalyze the oxidation and decomposition reactions of the substances contained in the tea leaves, further accelerating fermentation. Improving the steam penetration efficiency can make the humidity distribution in the tea pile more uniform, avoiding the problem of excessively high or low humidity in some areas. This helps to ensure the uniformity of tea fermentation and makes the fermentation effect of the entire tea pile consistent.

[0038] It is worth noting that in the above embodiments, the steam spraying mechanism 4 needs to be connected to an external steam generator through the connecting pipe 405. These are all existing technologies and not the main innovations, so they will not be described in detail here.

[0039] This invention provides a tea processing and fermentation apparatus. 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.
