Abstract
Description
Technical Field
[0001] This invention relates to the field of food processing technology, and in particular to an intelligent fermentation tank unit suitable for food processing. Background Technology
[0002] In the fermentation process of food processing, the fermentation tank is a core and critical piece of equipment. The stability and cleanliness of its internal fermentation environment directly affect the fermentation quality and safety of the food. During fermentation, food materials easily adhere to the inner wall of the fermentation tank due to the viscosity changes caused by the fermentation reaction and the centrifugal force during stirring. If these adhered materials are not cleaned in time, it will not only lead to material waste but may also cause spoilage due to prolonged retention, thereby contaminating the fermented food in batches and affecting the consistency of product quality.
[0003] To address the issue of material adhesion, existing fermenters are typically equipped with wall-scraping mechanisms. However, traditional wall-scraping mechanisms have significant drawbacks: most are fixedly installed, maintaining contact with the inner wall of the fermenter throughout its entire operating cycle. While this design achieves the desired scraping effect, prolonged contact friction significantly increases wear between the scraping mechanism and the inner wall, shortening the equipment's lifespan. Furthermore, continuous frictional resistance increases power consumption and operating costs. In addition, the fixed scraping force cannot be flexibly adjusted for fermentation scenarios involving food materials of varying viscosities and types, easily leading to incomplete scraping or excessive scraping that damages the inner wall, making it difficult to adapt to the diverse fermentation needs of food processing. Therefore, this paper proposes an intelligent fermentation tank unit suitable for food processing to solve these problems. Summary of the Invention
[0004] This invention addresses the problems of traditional wall-scraping mechanisms, which use fixed installations and cannot be flexibly adjusted, easily leading to incomplete scraping or excessive scraping that damages the inner wall of the tank. It provides an intelligent fermentation tank unit suitable for food processing. This intelligent tank unit uses speed control to achieve contact or disengagement between the wall-scraping mechanism and the inner wall of the fermentation tank, overcoming the design flaw of traditional wall-scraping mechanisms that involve long-term contact and friction. During the fermentation stage when scraping is not required, the wall-scraping mechanism can detach from the inner wall of the tank, avoiding ineffective friction, significantly reducing the wear and tear on the scraping components and the inner wall of the tank, reducing equipment maintenance frequency and replacement costs, effectively extending the service life of the entire fermentation tank unit, and effectively solving the problems mentioned in the background art.
[0005] The technical solution adopted by the present invention to solve the above problems is as follows: A smart fermentation tank assembly suitable for food processing includes a support frame with multiple fermentation tanks at the upper end of the support frame, and a screening machine at the upper end of each fermentation tank. Each fermentation tank includes a fermentation barrel, and each fermentation barrel has a rotatable cylindrical shaft inside. Each cylindrical shaft has a stirring mechanism on its outer surface, and each stirring mechanism includes multiple stirring shafts. When the cylindrical shaft rotates, the stirring shafts can move in a circular motion while rotating. A centrifugal device is also provided on the outer surface of the cylindrical shaft. The centrifugal device includes a circular base, and each circular base has a wall scraping mechanism on both sides. Each wall scraping mechanism includes a vertical scraper. When the cylindrical shaft rotates, the centrifugal device can operate and the vertical scraper can move in a circular motion. When the centrifugal device is operating, the vertical scraper can also move outward.
[0006] The centrifugal device also includes a first annular sleeve fitted on the outer surface of the cylindrical shaft, and a first spring fitted on the outer surface of the cylindrical shaft to cooperate with the first annular sleeve. Centrifugal rods are hinged to both sides of the upper end of the circular base, and centrifugal balls are provided at the upper ends of the centrifugal rods. Short connecting rods inclined to the outer side of the lower end are hinged to the outer surface of the first annular sleeve, and the lower ends of the short connecting rods are hinged to the corresponding centrifugal rods.
[0007] Both sides of the circular base are provided with extension plates, and push plates are slidably connected to the inner walls of the extension plates. Vertical scrapers are fixed to the outer end faces of the two push plates. The upper ends of the push plates are also hinged to long connecting rods that tilt inward. The upper ends of the long connecting rods are hinged to the corresponding centrifugal rods.
[0008] Each of the extension plates is equipped with a horizontal scraper at its lower end. When the vertical scraper moves outward, the horizontal scraper can move downward.
[0009] The horizontal scrapers are all slidably connected to the lower end of the extension plate, and the upper surface of the push plate is fixedly connected to the guide frame. The upper end of the horizontal scraper is provided with a first sliding pin, and the guide frame is provided with a slanted keyway that cooperates with the first sliding pin.
[0010] Each vertical scraper has an L-shaped telescopic scraper slidably connected to the inner wall of its lower end, and the lower ends of the L-shaped telescopic scrapers are slidably connected to the inner wall of the corresponding horizontal scraper.
[0011] Each stirring mechanism includes multiple second ring sleeves fitted on the outer surface of the cylindrical shaft. The stirring shafts are rotatably connected to both sides of the corresponding second ring sleeves. Planetary bevel gears are coaxially fixed to the inner sides of both stirring shafts. A stellar bevel gear that meshes with the planetary bevel gear is provided at the upper end of each second ring sleeve. Multiple stirring rods are provided on the outer surface of each stirring shaft.
[0012] The upper surface of the second ring sleeve is fixedly connected to a connecting plate, and the stellar bevel gears are rotatably connected to the inner wall of the connecting plate. A limiting shaft fixedly connected to the fermentation tank is provided at the center of the cylinder shaft, and the stellar bevel gears are slidably connected to the outer surface of the limiting shaft.
[0013] Two long guide rods are fixedly attached to the outer surface of the first ring sleeve, and the second ring sleeve is fixedly attached to the outer surface of the corresponding two long guide rods.
[0014] The inner wall of each stirring shaft is provided with multiple small spur gears. Each small spur gear is coaxially fixed with a paddle on both sides. Each stirring shaft is slidably connected to a long rack that meshes with the small spur gear. Each of the two outer ends of the stirring shaft is slidably connected to a connecting shaft. Each long rack is rotatably connected to the inner end of the two connecting shafts. Each of the two outer ends of the connecting shafts is rotatably connected to a vertical slider. Each vertical slider is slidably connected to the inner wall of the vertical scraper.
[0015] Compared with the prior art, the present invention has the following advantages: In use, this invention, by starting the motor, enables the drum shaft to rotate. When the drum shaft rotates irregularly at a low speed within a designated area, it drives the centrifuge and stirring mechanisms to work normally. When the stirring mechanism is working, it causes the stirring shaft to move in a circular motion while rotating, thereby uniformly stirring the materials inside the fermentation tank. When the centrifuge mechanism is working, it drives the stirring shaft to move up and down reciprocally, enabling large-area rotation inside the fermentation tank. When the drum shaft rotates at a constant speed, i.e., when the centrifuge is in a designated position, the stirring shaft will also be at a designated height, allowing it to perform stirring at that height. When the drum shaft rotates irregularly at a low speed within a designated area, it also drives the vertical scraper to move outward or inward, without the vertical scraper making contact with the outside. When the vertical scraper moves in a circular motion to the inner wall of the fermentation tank, it acts as a stirrer without contacting the inner wall, reducing wear on the equipment. As the vertical scraper moves inward or outward, it drives the paddles to rotate back and forth, agitating the surrounding material and ensuring more even mixing, further improving the stirring effect. When it's necessary to scrape away material adhering to the inner wall of the fermentation tank, the motor is controlled to increase the rotation speed of the drum shaft to a specified value. At this point, under the operation of the centrifugal device, the vertical scraper moves outward to contact the inner wall of the fermentation tank, and the horizontal scraper moves downward to contact the bottom wall. This circular movement of the vertical and horizontal scrapers effectively cleans the inner wall of the fermentation tank, especially when the material is highly adhesive. By further increasing the rotational speed of the cylinder shaft, under the operation of the centrifugal device, the vertical scraper has an outward driving force, squeezing and contacting the inner wall of the fermentation tank, while the horizontal scraper has a downward driving force, squeezing and contacting the bottom wall of the fermentation tank. This allows for more effective scraping of materials adhering to the inner wall of the fermentation tank. This intelligent tank unit achieves contact or disengagement between the scraping mechanism and the inner wall of the fermentation tank through speed control, overcoming the design flaw of traditional scraping mechanisms that involve long-term contact and friction. During the fermentation stage when scraping is not required, the scraping mechanism can detach from the inner wall of the tank, avoiding ineffective friction, significantly reducing the wear and tear on the scraping components and the inner wall of the tank, reducing equipment maintenance frequency and replacement costs, and effectively extending the service life of the entire fermentation tank unit. When the scraping mechanism detaches from the inner wall of the tank, the equipment operation... The process significantly reduces frictional resistance, resulting in lower power output requirements and reduced energy consumption such as electricity. Simultaneously, the reduced frequency of replacement of worn parts further compresses equipment maintenance costs and improves the economic efficiency of food processing enterprises. For different fermentation scenarios involving various materials in food processing, the working state of the scraping mechanism can be precisely adjusted by controlling the rotation speed. For fermentation of highly viscous materials, controlling the scraping mechanism to contact the inner wall ensures thorough scraping, preventing material adhesion and deterioration. For fermentation stages involving low-viscosity materials or those requiring less frequent scraping, controlling the scraping mechanism to detach from the inner wall avoids excessive scraping that could interfere with the fermentation environment. This flexible adaptability ensures the stability of different fermentation processes and helps improve the consistency of quality in various fermented foods.By controlling the working state of the scraping mechanism through speed linkage, the installation position of the scraping components can be adjusted manually, achieving automation and intelligence in the scraping operation. Operators can preset speed parameters according to different fermentation process requirements to precisely control the contact and disengagement of the scraping mechanism, reducing the intensity of manual operation and human error. This facilitates integration into intelligent food processing production lines and improves overall production efficiency. Attached Figure Description

Detailed Implementation
[0025] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0026] like Figures 1-8 As shown, the present invention provides an intelligent fermentation tank assembly suitable for food processing, including a support frame 1. Multiple fermentation tanks are mounted on the upper end of the support frame 1, and a screening machine 3 is mounted on the upper end of each fermentation tank. Each fermentation tank includes a fermentation barrel 5, and each fermentation barrel 5 has a rotatable cylindrical shaft 8 inside. A stirring mechanism is mounted on the outer surface of each cylindrical shaft 8, and each stirring mechanism includes multiple stirring shafts 32. When the cylindrical shaft 8 rotates, the stirring shafts 32 can move in a circular motion while rotating. A centrifugal device is also mounted on the outer surface of the cylindrical shaft 8. The centrifugal device includes a circular base 9, and scraping mechanisms are mounted on both sides of the circular base 9. Each scraping mechanism includes a vertical scraper 24. When the cylindrical shaft 8 rotates, the centrifugal device can operate, and the vertical scraper 24 can move in a circular motion. When the centrifugal device is operating, the vertical scraper 24 can also move outwards.
[0027] like Figures 1-5As shown, the support frame 1 supports the entire device. The fermenter also includes an outer cylinder 2, which is fixed to the inner wall of the support frame 1, essentially fixing the fermenter to the support frame 1. The fermentation tank 5 is fixed to the inner wall of the outer cylinder 2. A heating pipe 4 is provided on the outer surface of the fermentation tank 5 to control the temperature of the fermenter. The upper end of the fermenter is equipped with a detachable top cover 6, and a motor 7 is located on the upper end of the top cover 6. The cylinder shaft 8 is fixed to the output end of the motor 7. The function of the motor 7 is to provide rotational power to the cylinder shaft 8. The motor 7 is existing technology and will not be described in detail. The bottom of the fermenter is equipped with an electrically controlled valve 39. When the electrically controlled valve 39 is opened, the product inside the fermenter can be released. The electrically controlled valve 39 is existing technology and will not be described in detail. The screening machine 3 can separate the raw materials into solid and liquid components, such as... During fruit processing, the screening machine 3 can separate the pulp and juice, which are then fed into their respective fermentation tanks. The screening machine 3 is existing technology and will not be described further. A rotating cylindrical shaft 8 drives the stirring mechanism, centrifugal device, and wall scraping mechanism to work synchronously. When the stirring mechanism is working, i.e., the stirring shaft 32 moves and rotates in a circular motion, it can uniformly mix the materials in the fermentation tank over a large area. When the cylindrical shaft 8 rotates, the vertical scraper 24 can move in a circular motion. Under normal conditions, the vertical scraper 24 can disengage from the inner wall of the fermentation tank 5, reducing wear between equipment. While the vertical scraper 24 is moving in a circular motion, it also stirs the inside of the fermentation tank. When the centrifugal device is working, it can drive the vertical scraper 24 outwards. When the vertical scraper 24 moves laterally and contacts the inner wall of the fermentation tank 5, it moves in a circular motion to clean the inner wall of the fermentation tank 5. The centrifugal device applies a driving force to move the vertical scraper 24 outward, which is the squeezing force exerted by the vertical scraper 24 on the fermentation tank 5. This squeezing force is related to the rotational speed of the cylinder shaft 8; the higher the rotational speed of the cylinder shaft 8, the greater the squeezing force of the vertical scraper 24 on the fermentation tank 5. Similarly, the lower the rotational speed of the cylinder shaft 8, the smaller the squeezing force of the vertical scraper 24 on the fermentation tank 5. This allows for adaptive adjustment based on the viscosity of the material. This intelligent tank unit achieves contact or disengagement between the scraping mechanism and the inner wall of the fermentation tank through rotational speed control, overcoming the design flaw of long-term contact friction in traditional scraping mechanisms. During the fermentation stage where scraping is not required, the scraper... The wall-scraping mechanism can detach from the inner wall of the tank, avoiding unnecessary friction, significantly reducing the wear and tear between the scraping components and the inner wall of the tank, reducing equipment maintenance frequency and replacement costs, and effectively extending the service life of the entire fermentation tank unit. When the wall-scraping mechanism detaches from the inner wall of the tank, the frictional resistance during equipment operation is greatly reduced, correspondingly reducing the power output demand, thereby reducing energy consumption such as electricity. At the same time, the replacement frequency of worn parts is reduced, further compressing equipment operation and maintenance costs and improving the economic benefits of food processing enterprises. For different types of material fermentation scenarios in food processing, the working state of the wall-scraping mechanism can be adjusted by precisely controlling the rotation speed. For the fermentation of highly viscous materials, controlling the contact between the wall-scraping mechanism and the inner wall can achieve thorough wall scraping, preventing material adhesion and deterioration.For low-viscosity materials or fermentation stages where frequent scraping is not required, controlling the scraping mechanism to detach from the inner wall avoids excessive scraping that could interfere with the fermentation environment. This flexibility ensures the stability of different fermentation processes and helps improve the consistency of quality in various fermented foods. By controlling the scraping mechanism's operation through speed linkage, manual adjustment of the scraping components' installation position is eliminated, achieving automation and intelligence in the scraping operation. Operators can preset speed parameters according to different fermentation process requirements to precisely control the contact and disengagement of the scraping mechanism, reducing manual labor intensity and human error. This facilitates integration into intelligent food processing production lines, improving overall production efficiency.
[0028] The centrifugal device also includes a first annular sleeve 15 sleeved on the outer surface of the cylindrical shaft 8. A first spring 11 that cooperates with the first annular sleeve 15 is also sleeved on the outer surface of the cylindrical shaft 8. Centrifugal rods 12 are hinged to both sides of the upper end of the circular base 9. Centrifugal balls 13 are provided at the upper end of the centrifugal rods 12. Short connecting rods 14 that are inclined to the outer side of the lower end are hinged to the outer surface of the first annular sleeve 15. The lower ends of the short connecting rods 14 are all hinged to the corresponding centrifugal rods 12.
[0029] like Figure 5 As shown, the first spring 11 always exerts an upward driving force on the first annular sleeve 15, keeping the first annular sleeve 15 in its highest position under normal conditions. Retaining rings 16 that cooperate with the first annular sleeve 15 are fixed to the outer surface of the cylinder shaft 8. These retaining rings 16 prevent the first annular sleeve 15 from moving upwards, even if it is in its highest position under normal conditions and can contact the retaining rings 16. The installation and shape of the centrifugal rod 12, centrifugal ball 13, and short connecting rod 14 are as follows: Figure 5As shown, the circular base 9 is fixed to the outer surface of the cylindrical shaft 8, the lower end of the first spring 11 is fixed to the upper surface of the circular base 9, and the upper end of the first spring 11 is fixed to the first annular sleeve 15. The first annular sleeve 15 can slide up and down on the outer surface of the cylindrical shaft 8. When the cylindrical shaft 8 rotates, it can drive the circular base 9, centrifugal rod 12, centrifugal ball 13, short connecting rod 14, and first annular sleeve 15 to move synchronously in a circular motion. When the centrifugal ball 13 moves in a circular motion, it can move outward under the action of centrifugal force, which can drive the centrifugal rod 12 to flip downward, pull the lower end of the short connecting rod 14 to move downward, and the upper end of the short connecting rod 14 drives the first annular sleeve 15 to move downward. When moving, the first spring 11 can be compressed. When the rotation speed of the cylinder shaft 8 is large, the centrifugal ball 13 can move downward by a larger stroke, that is, the centrifugal rod 12 flips downward by a larger angle, and the corresponding first ring sleeve 15 moves downward by a larger stroke. Similarly, when the rotation speed of the cylinder shaft 8 is small, the centrifugal ball 13 moves downward by a smaller stroke, the centrifugal rod 12 flips downward by a smaller angle, and the first ring sleeve 15 moves downward by a smaller stroke. The rotation speed of the cylinder shaft 8 can change the magnitude of the centrifugal force of the centrifugal ball 13, thereby changing the movement stroke of the corresponding parts. When the cylinder shaft 8 stops rotating, the corresponding centrifugal ball 13, first ring sleeve 15, etc. will move upward and reset under the elastic force of the first spring 11.
[0030] Both sides of the circular base 9 are provided with extension plates 10, and push plates 18 are slidably connected to the inner walls of the extension plates 10. Vertical scrapers 24 are fixed to the outer end faces of the two push plates 18. The upper ends of the push plates 18 are also hinged to long connecting rods 17 that are inclined inward. The upper ends of the long connecting rods 17 are hinged to the corresponding centrifugal rods 12.
[0031] like Figure 5As shown, the extension plate 10 and the circular base 9 are integrally formed. The push plate 18 can slide left and right on the inner wall of the extension plate 10. It is fixed to the outer end face of the extension plate 10 by the vertical scraper 24. That is, when the two extension plates 10 move outward or inward, they can drive the vertical scraper 24 to move outward or inward. Through the provided long connecting rod 17, when the two centrifugal rods 12 flip outward, they can drive the long connecting rod 17 to move outward. The long connecting rod 17 can also push the push plate 18 and the vertical scraper 24 to move outward, so that the vertical scraper 24 contacts the inner wall of the fermentation tank 5. Through the provided centrifugal ball 13, it can adjust the rotation speed of the cylinder shaft 8 according to the rotation speed of the cylinder shaft 8. The position of the vertical scraper 24 is adjusted so that when the cylinder shaft 8 rotates within a specified low-speed range, the vertical scraper 24 will not contact the fermentation tank 5. When it is necessary to clean the inner wall of the fermentation tank 5, increasing the rotation speed of the cylinder shaft 8 allows the vertical scraper 24 to move outward and contact the inner wall of the fermentation tank 5, thereby cleaning the inner wall of the fermentation tank 5. When the viscosity of the raw material in the fermentation tank 5 is high, that is, when the adhesion of the raw material adhering to the inner wall of the fermentation tank 5 is large, further increasing the rotation speed of the cylinder shaft 8 increases the squeezing force of the scraper on the inner wall of the fermentation tank 5, allowing for more powerful and cleaner cleaning of the raw material adhering to the inner wall of the fermentation tank 5. Figure 3 As shown, in order to improve the stability of the vertical scraper 24, a centrifugal device can also be added to the upper end of the outer surface of the cylinder shaft 8. Through the limiting drive of the vertical scraper 24 by the two sets of centrifugal devices, the vertical scraper 24 can move stably inward or outward.
[0032] Each of the extension plates 10 is provided with a horizontal scraper 23 at its lower end. When the vertical scraper 24 moves outward, the horizontal scraper 23 can move downward.
[0033] like Figures 4-5 As shown, the horizontal scraper 23 can clean the bottom of the fermentation tank 5, thereby preventing sedimentation and raw material adhesion. Under normal conditions, the horizontal scraper can disengage from the bottom wall of the fermentation tank 5. That is, when the vertical scraper 24 moves outward, it can drive the horizontal scraper 23 to move downward. When the vertical scraper 24 moves outward and contacts the inner wall of the fermentation tank 5, the horizontal scraper 23 can move downward to the bottom wall of the fermentation tank 5, thus cleaning the inner wall and bottom wall of the fermentation tank 5 simultaneously.
[0034] The horizontal scrapers 23 are all slidably connected to the lower end of the extension plate 10. The upper surface of the push plate 18 is fixedly connected to the guide frame 19. The upper end of the horizontal scraper 23 is provided with a first sliding pin 20. The guide frame 19 is provided with a slanted keyway 21 that cooperates with the first sliding pin 20.
[0035] like Figures 4-5As shown, two short guide rods 22 are fixedly attached to the upper surface of the horizontal scraper 23. Ear plates are fixedly attached to both ends of the extension plate 10. The short guide rods 22 are slidably connected to the inner wall of the ear plates. Support seats are fixedly attached to the upper surfaces of the two short guide rods 22. The first sliding pins 20 are fixedly attached to the inner walls of the two support seats. With the short guide rods 22 limiting the horizontal scraper 23, it is equivalent to the horizontal scraper 23 being slidably connected to the lower end of the extension plate 10. When the extension plate 10 rotates, it can drive the horizontal scraper 23 to rotate, and the horizontal scraper 23 can move up and down. The guide frame 19 and the first sliding pins 20 are installed and shaped as follows. Figure 5 As shown, when the push plate 18, guide frame 19, vertical scraper 24, etc. move outward, the horizontal scraper 23 can be driven to move downward through the engagement of the first sliding pin 20 and the inclined keyway 21. That is, the vertical scraper 24 moves outward and the horizontal scraper 23 moves downward, thereby contacting the inner wall and bottom wall of the fermentation tank 5. When the horizontal scraper 23 and the vertical scraper 24 rotate and move, the inner wall and bottom wall of the fermentation tank 5 can be cleaned and scraped.
[0036] The lower inner wall of each vertical scraper 24 is slidably connected to an L-shaped telescopic scraper 25, and the lower ends of each L-shaped telescopic scraper 25 are slidably connected to the inner wall of the corresponding horizontal scraper 23.
[0037] like Figures 4-5 As shown, the L-shaped telescopic scraper 25 can slide up and down on the inner wall of the vertical scraper 24, and it can also slide left and right on the inner wall of the horizontal scraper 23. That is, when the vertical scraper 24 moves outward, it can drive the L-shaped telescopic scraper 25 to move outward and extend, that is, the L-shaped telescopic scraper 25 extends outward on the inner wall of the horizontal scraper 23. When the horizontal scraper 23 moves downward, it can drive the L-shaped telescopic scraper 25 to move downward and extend, that is, the L-shaped telescopic scraper 25 extends downward on the inner wall of the vertical scraper 24. When the vertical scraper 24 moves outward and the horizontal scraper 23 moves downward, it can drive the L-shaped telescopic scraper 25 to move outward and downward at the same time, so that the L-shaped telescopic scraper 25 contacts the corner of the bottom wall of the fermentation tank 5; thus, the inner wall of the fermentation tank 5 can be cleaned without dead angles.
[0038] Each stirring mechanism includes multiple second annular sleeves 27 sleeved on the outer surface of the cylindrical shaft 8. Each stirring shaft 32 is rotatably connected to both sides of the corresponding second annular sleeve 27. Planetary bevel gears 30 are coaxially fixed to the inner side of each of the two stirring shafts 32. Each second annular sleeve 27 is provided with a stellar bevel gear 29 that meshes with the planetary bevel gears 30. Multiple stirring rods 33 are provided on the outer surface of each stirring shaft 32.
[0039] like Figures 6-7As shown, the stirring rod 33 is fixed to the outer surface of the stirring shaft 32. The inner walls of the stirring shaft 32 and the planetary bevel gear 30 are both fixed with rotating shafts. The rotating shafts are rotatably connected to the inner wall of the second ring sleeve 27, which is equivalent to the stirring shaft 32 being rotatably connected to both sides of the second ring sleeve 27. The second ring sleeve 27 can slide up and down on the outer surface of the cylindrical shaft 8. When the cylindrical shaft 8 rotates, it can drive the second ring sleeve 27 to rotate. When the cylindrical shaft 8 and the second ring sleeve 27 rotate, they can drive the planetary bevel gear 30, the stirring shaft 32, the stirring rod 33, etc. to move synchronously in a circular motion. When the planetary bevel gear 30 moves in a circular motion, it can rotate through meshing with the stellar bevel gear 29. When the planetary bevel gear 30 rotates, it can drive the stirring shaft 32 to rotate. That is, when the cylindrical shaft 8 rotates, it can drive the stirring shaft 32 to move in a circular motion while rotating, thereby uniformly stirring the material inside the fermentation tank 5.
[0040] The upper surface of the second ring sleeve 27 is fixedly connected to a connecting plate 28, and the stellar bevel gears 29 are rotatably connected to the inner wall of the connecting plate 28. The center of the cylinder shaft 8 is provided with a limiting shaft 31 fixedly connected to the fermentation tank 5, and the stellar bevel gears 29 are slidably connected to the outer surface of the limiting shaft 31.
[0041] like Figure 3 and 7 As shown, the connecting plate 28 serves to support and limit the stellar bevel gear 29. That is, when the second annular sleeve 27 moves up and down, it drives the connecting plate 28, the stellar bevel gear 29, and the planetary bevel gear 30 to move up and down synchronously, ensuring that the planetary bevel gear 30 and the stellar bevel gear 29 are always meshed and will not disengage. Figure 3 As shown, the upper end of the limiting shaft 31 is rotatably connected to the inner wall of the upper end of the cylindrical shaft 8, and a four-jaw bracket is fixed to the lower end of the outer surface of the limiting shaft 31. The four-jaw bracket is fixed to the inner wall of the fermentation tank 5, which is equivalent to the limiting shaft 31 being fixed to the inner wall of the fermentation tank 5, thus limiting the rotation of the limiting shaft 31. The stellar bevel gear 29 and the limiting shaft 31 are connected by a spline. The stellar bevel gear 29 can slide up and down on the outer surface of the limiting shaft 31, and can also limit the rotation of the stellar bevel gear 29. That is, when the planetary bevel gear 30 moves in a circle, through meshing with the stellar bevel gear 29, the planetary bevel gear 30, the stirring shaft 32, etc. can rotate synchronously.
[0042] Two long guide rods 26 are fixedly attached to the outer surface of the first annular sleeve 15, and the second annular sleeve 27 is fixedly attached to the outer surface of the corresponding two long guide rods 26.
[0043] like Figure 3As shown, ear plates are fixed to both the front and rear ends of the outer surfaces of the first ring sleeve 15 and the second ring sleeve 27. The ear plates are fixed to the outer surface of the long guide rod 26. That is, when the first ring sleeve 15 moves up and down, it can drive the long guide rod 26 to move up and down. When the long guide rod 26 moves up and down, it can drive the second ring sleeve 27 to move up and down, that is, the stirring mechanism moves up and down. When the stirring mechanism moves up and down, it can further increase the stirring range. That is, when the cylinder shaft 8 rotates, it can drive the centrifuge device and the stirring mechanism to work simultaneously. When the stirring mechanism works, it can drive the stirring shaft 32 to move in a circular motion while rotating. When the centrifuge device works, it can drive the stirring shaft 32 to move up and down reciprocally, thereby comprehensively and evenly mixing the raw materials in the fermentation tank 5.
[0044] The inner wall of each stirring shaft 32 is provided with multiple small spur gears 35. Each small spur gear 35 is coaxially fixed with a paddle 34 on both sides. Each stirring shaft 32 has a long rack 36 that meshes with the small spur gear 35. The inner walls of the outer ends of the two stirring shafts 32 are slidably connected to a connecting shaft 37. The long rack 36 is rotatably connected to the inner ends of the two connecting shafts 37. The outer ends of the two connecting shafts 37 are rotatably connected to a vertical slider 38. The vertical slider 38 is slidably connected to the inner wall of the vertical scraper 24.
[0045] like Figure 8 As shown, a rotating shaft is fixedly connected to the inner wall of the center of the small spur gear 35 and the paddle 34. Both shafts are rotatably connected to the inner wall of the stirring shaft 32. The long rack 36 can slide left and right on the inner wall of the stirring shaft 32. When the long rack 36 slides left and right on the inner wall of the stirring shaft 32, the meshing of the long rack 36 and the small spur gear 35 drives the paddle 34 to reciprocate in both directions. When the paddle 34 reciprocates in both directions, it can move the surrounding material, thereby making the material mix more evenly and further improving the stirring effect. Connecting seats are fixedly connected to the outer end face of the long rack 36. These connecting seats are rotatably connected to the inner side of the outer surface of the connecting shaft 37. The connecting shaft 37 can... The stirring shaft 32 moves left and right and rotates on the inner wall of the stirring shaft 32. That is, when the stirring shaft 32 rotates and the long toothed rack 36 moves in a circle, it does not affect the connection with the connecting shaft 37. The connecting shaft 37 can also drive the long toothed rack 36 to move left and right, and the two movements do not affect each other. The vertical slider 38 can slide up and down on the inner wall of the vertical scraper 24. That is, when the stirring shaft 32 moves up and down, it can drive the connecting shaft 37, the vertical slider 38, etc. to move up and down synchronously. And when the vertical scraper 24 moves inward or outward, it can drive the vertical slider 38, the connecting shaft 37, etc. to move inward or outward synchronously, that is, drive the long toothed rack 36 to move and the paddle 34 to rotate in both directions.
[0046] In use, the invention enables the cylinder shaft 8 to rotate by starting the motor 7. When the cylinder shaft 8 rotates irregularly at a low speed within a designated area, it drives the centrifugal device and stirring mechanism to work normally. When the stirring mechanism is working, it causes the stirring shaft 32 to move and rotate in a circular motion, thereby uniformly stirring the material inside the fermentation tank 5. When the centrifugal mechanism is working, it drives the stirring shaft 32 to move up and down reciprocally, enabling large-area rotation inside the fermentation tank 5. When the rotational speed of the cylinder shaft 8 is constant, i.e., when the centrifugal device is in a designated position, the stirring shaft 32 will also be at a designated height, allowing the stirring shaft 32 to perform stirring work at that designated height. When the cylinder shaft 8 rotates irregularly at a low speed within a designated area, it also drives the vertical scraper 24 to move outward or towards... When the vertical scraper 24 moves inward, it will not contact the inner wall of the fermentation tank 5. This means that as the vertical scraper 24 moves circumferentially, it can perform a stirring function without contacting the inner wall of the fermentation tank 5, reducing equipment wear. When the vertical scraper 24 moves inward or outward, it can drive the paddle 34 to rotate back and forth, stirring the surrounding material and making the mixture more uniform, further improving the stirring effect. When it is necessary to scrape off the material adhering to the inner wall of the fermentation tank 5, the speed of the cylinder shaft 8 is increased to a specified value by controlling the motor 7. At this time, under the operation of the centrifugal device, the vertical scraper 24 can move outward to contact the inner wall of the fermentation tank 5, and the horizontal scraper 23 can move downward to contact the bottom wall of the fermentation tank 5. That is, at this time, the vertical scraper 24... When the horizontal scraper 23 moves in a circular motion, it can clean the inner wall of the fermentation tank 5. When the material has strong adhesion, by further increasing the rotation speed of the cylinder shaft 8, under the operation of the centrifugal device, the vertical scraper 24 has an outward driving force to squeeze and contact the inner wall of the fermentation tank 5, and the horizontal scraper 23 has a downward driving force to squeeze and contact the bottom wall of the fermentation tank 5, which can more effectively scrape the material adhering to the inner wall of the fermentation tank 5. This intelligent tank unit realizes the contact or disengagement of the scraping mechanism with the inner wall of the fermentation tank through rotation speed control, which changes the design defect of long-term contact friction of the traditional scraping mechanism. In the fermentation stage where scraping is not required, the scraping mechanism can disengage from the inner wall of the tank, avoiding ineffective friction, significantly reducing the wear of the scraping parts and the inner wall of the tank, and reducing the frequency of equipment maintenance. This reduces replacement costs and effectively extends the service life of the entire fermentation tank unit. When the scraping mechanism detaches from the inner wall of the tank, the frictional resistance during equipment operation is significantly reduced, resulting in lower power output requirements and reduced energy consumption such as electricity. Simultaneously, the frequency of replacement of worn parts decreases, further reducing equipment maintenance costs and improving the economic benefits for food processing enterprises. For different types of material fermentation scenarios in food processing, the working state of the scraping mechanism can be adjusted by precisely controlling the rotation speed. For fermentation of highly viscous materials, controlling the scraping mechanism to contact the inner wall ensures thorough scraping, preventing material adhesion and deterioration. For fermentation stages of low-viscosity materials or those that do not require frequent scraping, controlling the scraping mechanism to detach from the inner wall avoids excessive scraping that could interfere with the material fermentation environment.This flexibility ensures the stability of different fermentation processes, helping to improve the consistency of quality in various fermented foods. By controlling the working state of the scraping mechanism through speed linkage, manual adjustment of the scraping component's installation position is eliminated, achieving automation and intelligence in the scraping operation. Operators can preset speed parameters according to different fermentation process requirements to precisely control the contact and disengagement of the scraping mechanism, reducing manual operation intensity and human error. This facilitates integration into intelligent food processing production lines, improving overall production efficiency.
