Abstract
Description
Technical Field
[0001] This invention relates to the field of fermentation tank technology, specifically a sealed temperature-controlled fermentation tank for fermenting Astragalus compound probiotics. Background Technology
[0002] Astragalus, a traditional food and medicine ingredient, contains polysaccharides, flavonoids and other active ingredients that have immunomodulatory and antioxidant effects. Probiotics (such as lactic acid bacteria and bifidobacteria) play a significant role in maintaining intestinal health and nutrient conversion. Fermenting astragalus with probiotics can improve the dissolution rate and bioavailability of the effective components of astragalus through microbial metabolism, while also enhancing the colonization ability of probiotics. Related fermented products have broad application prospects in the food and health product fields. During the fermentation process of astragalus compound probiotics, microbial metabolism and swelling of astragalus raw materials will continuously generate a large number of bubbles. These bubbles accumulate on the surface of the fermentation liquid, which will lead to an imbalance in the microbial metabolic environment.
[0003] Existing technologies using chemical defoamers or mechanical extrusion / puncture defoaming methods have significant drawbacks: Firstly, some fermenters use chemical defoamers, which can quickly break bubbles, but the residue of these defoamers can affect the purity and safety of the fermentation products. Furthermore, some defoamers can interfere with the metabolic activity of probiotics, reducing the number of live bacteria in the fermentation products. Secondly, other fermenters use mechanical defoaming structures such as extrusion and puncture. These structures are often fixed scrapers or rigid puncture components, and the physical impact during operation can easily cause the cell membranes of probiotics to rupture and lose their activity, further affecting the fermentation effect. Therefore, we propose a sealed temperature-controlled fermenter for Astragalus compound probiotic fermentation to solve the above problems. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a sealed temperature-controlled fermentation tank for Astragalus compound probiotic fermentation, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A sealed temperature-controlled fermentation tank for fermenting Astragalus compound probiotics includes a tank body, a float plate is provided inside the tank body, a stirring assembly installed inside the tank body is provided below the float plate, and a degassing assembly installed inside the tank body is provided above the float plate. The stirring assembly includes two connecting frames disposed inside the tank. Mixing plates are fixed to both side walls of the connecting frames. Two transmission rods are rotatably connected to each connecting frame via pins. Corresponding transmission rods are rotatably connected to a connecting block adapted to the inner wall of the tank via bearings. A drive shaft is rotatably connected inside the tank via bearings. The lower connecting frame is fixed to the surface of the drive shaft, and the upper connecting frame slides on the surface of the drive shaft. A linkage component for driving the upper connecting frame to move synchronously is installed at the bottom of the float plate. In addition to the bubble assembly, the system includes two guide seats fixed to the top of the float plate. Two annular plates are slidably connected between the two guide seats. Each annular plate has two sets of elastic strips installed inside. The length of the elastic strips is adapted to the shape of the annular plate. A telescopic ring one is fixed to the bottom of the lower annular plate and is fixedly connected to the float plate at the bottom. A telescopic ring two is fixed to the bottom of the upper annular plate and is fixedly connected to the lower annular plate at the bottom. A protective ring is fixed to the top of the upper annular plate. Two impact plates are fixed to the surface of both annular plates. A reciprocating mechanism for driving the two annular plates to move up and down synchronously is installed inside the tank.
[0006] Furthermore, the linkage includes an annular rail fixed to the top of the float, an annular groove of the annular rail is rotatably connected to a ring bar, four connecting rods are fixed to the bottom of the annular bar, and the other end of each connecting rod is fixedly connected to the connecting frame above.
[0007] Furthermore, two mixing aid plates are fixed to one side wall of the left connecting block, and two mixing aid plates are fixed to one side wall of the right connecting block, which are adapted to the mixing aid plates. The mixing aid plates slide on the corresponding mixing aid plates.
[0008] Furthermore, the reciprocating mechanism includes a housing fixed inside the tank. Inside the housing, two auxiliary rotating rods are rotatably connected via bearings. The top of each auxiliary rotating rod is movably connected to a T-shaped reciprocating rod. One end of each T-shaped reciprocating rod slides through the housing to its outside and is fixed to a limiting rail. A sliding groove in the limiting rail is slidably connected to a moving rod. One side wall of each moving rod is rotatably connected to two connecting rods via bearings. The other end of each connecting rod is rotatably connected to a corresponding annular plate via bearings. Inside the housing, two guide blocks are fixed for limiting the T-shaped reciprocating rods. The T-shaped reciprocating rods slide on the corresponding guide blocks.
[0009] Furthermore, a main rotating rod is rotatably connected inside the housing via bearings. A driving gear is fixed to the surface of the main rotating rod, and driven gears are fixed to the surfaces of the two auxiliary rotating rods. The driven gears are meshed with the driving gears.
[0010] Furthermore, the housing is rotatably connected to a drive shaft adapted to the drive shaft via bearings. The bottom end of the drive shaft is inserted into a slot on the top of the drive shaft. A cathode electromagnetic plate is fixed to the top of the drive shaft, and an anode electromagnetic plate is fixed to the bottom of the main rotating rod. The bottom of the cathode electromagnetic plate is in contact with the top of the anode electromagnetic plate.
[0011] Furthermore, the top of the housing is provided with annular ventilation holes for heat dissipation of the driving gear and the driven gear.
[0012] Furthermore, a dust cover is installed on the top of the tank to protect the ventilation holes, and a filter screen is installed inside the dust cover.
[0013] Furthermore, an inlet pipe and an outlet pipe are connected and fixed on the tank body, and a telescopic pipe is connected and fixed at the bottom end of the inlet pipe. The bottom end of the telescopic pipe is connected and fixed to the inlet pipe on the float plate.
[0014] Furthermore, an outer protective shell is fixed to the outer wall of the tank, and an inlet pipe and an outlet pipe are connected and fixed on the outer protective shell.
[0015] Compared with the prior art, the present invention provides a sealed temperature-controlled fermentation tank for fermenting Astragalus compound probiotics, which has the following beneficial effects: This invention utilizes a defoaming component with a double-ring plate structure, elastic strip, and impact plate. When the two ring plates move up and down using a reciprocating mechanism, the impact plate and elastic strip vibrate. The elastic strip covers the center and edge areas of the liquid surface, thus breaking up bubbles without any blind spots. Compared to rigid rotational defoaming, the flexible vibration of the elastic strip results in less shear force and a lower risk of damage to probiotics and mycelium, thereby avoiding the adverse effects of bubbles on microbial metabolism during fermentation.
[0016] This invention utilizes the synergistic cooperation of the float and linkage components to form an adaptive adjustment mechanism. This mechanism can adjust the position in real time to address liquid level fluctuations caused by conditions such as feeding and evaporation. On one hand, it drives the agitator to maintain the optimal stirring depth below the liquid surface, effectively avoiding stirring blind spots or dry stirring caused by liquid level changes, and ensuring the uniformity of the fermentation liquid mixing. On the other hand, it ensures that the defoaming component is always above the liquid surface inside the tank, precisely targeting the bubble-rich area, thereby avoiding the adverse effects of operating condition fluctuations on stirring efficiency and defoaming effect. This achieves stable and reliable stirring and defoaming operations under various operating conditions, ensuring a controllable and efficient fermentation process. Attached Figure Description

Detailed Implementation
[0019] 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. Example
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8As shown in the figure, an embodiment of the present invention provides a sealed temperature-controlled fermentation tank for fermenting Astragalus compound probiotics, including a tank body 1. An outer shell 8 is fixed to the outer wall of the tank body 1. An inlet pipe 9 and an outlet pipe 10 are connected and fixed to the outer shell 8. An annular anti-scalding pad is also fixed to the surface of the outer shell 8, which can prevent workers from being scalded and also has a heat preservation function. A float plate 2 is provided inside the tank body 1. A stirring assembly 3 is installed inside the tank body 1 below the float plate 2. A degassing assembly 4 is installed inside the tank body 1 above the float plate 2. An inlet pipe 5 and an outlet pipe 6 are connected and fixed to the tank body 1. A telescopic pipe 7 is connected and fixed to the bottom end of the inlet pipe 5. The bottom end of the telescopic pipe 7 is connected and fixed to the inlet pipe on the float plate 2. The inlet end of the inlet pipe 5 penetrates the outer shell 8 and extends to its outside. A control valve is installed on the surface of the inlet pipe 5, while two control valves are installed on the outlet pipe 6. The telescopic pipe 7 is made of food-grade silicone, so it will not affect the fermentation liquid. The mixing assembly 3 includes two connecting frames 31 disposed inside the tank body 1. Mixing plates 32 are fixed to both side walls of the connecting frames 31. Two transmission rods 33 are rotatably connected to each connecting frame 31 via pins. Corresponding transmission rods 33 are rotatably connected to connecting blocks 34 adapted to the inner wall of the tank body 1 via bearings. Two first mixing plates 37 are fixed to one side wall of the left connecting block 34, and two second mixing plates 38 adapted to the first mixing plates 37 are fixed to one side wall of the right connecting block 34. The second mixing plates 38 slide on their corresponding first mixing plates 37. This arrangement further enhances the mixing speed of the Astragalus fermentation raw materials. The interior of the tank body 1 is permeable to... A drive shaft 35 is rotatably connected via a bearing. A servo motor is fixed at the bottom of the tank 1, and the output end of the servo motor is fixedly connected to the bottom end of the drive shaft 35. The lower connecting frame 31 is fixed to the surface of the drive shaft 35, and the upper connecting frame 31 slides on the surface of the drive shaft 35. A linkage 36 for driving the upper connecting frame 31 to move synchronously is installed at the bottom of the float 2. The linkage 36 includes an annular rail 361 fixed to the top of the float 2. An annular bar 362 is rotatably connected to the annular groove of the annular rail 361. Four connecting rods 363 are fixed at the bottom of the annular bar 362, and the other end of each connecting rod 363 is fixedly connected to the upper connecting frame 31. Besides the bubble assembly 4, the system includes two guide seats 41 fixed to the top of the float 2. Two annular plates 42 are slidably connected between the two guide seats 41. Each annular plate 42 has two sets of elastic strips 43 installed inside. The length of the elastic strips 43 is adapted to the shape of the annular plate 42. A telescopic ring 44 is fixed to the bottom of the lower annular plate 42, and the bottom of the telescopic ring 44 is fixedly connected to the float 2. A telescopic ring 45 is fixed to the bottom of the upper annular plate 42, and the bottom of the telescopic ring 45 is fixedly connected to the lower annular plate 42. The elastic strips 43 and the telescopic rings 44... Ring 1 44 and telescopic ring 2 45 are made of food-grade silicone, so they will not affect the fermentation products. The top of the upper annular plate 42 is fixed with a protective ring 46. The telescopic ring 1 44 and telescopic ring 2 45 are adapted to the moving trajectory of the upper and lower annular plates 42 respectively to achieve a seal and prevent air bubbles from escaping from the gaps. The protective ring 46 can further prevent air bubbles from overflowing. Two impact plates 47 are fixed on the surface of each of the two annular plates 42. The inside of the tank 1 is equipped with a reciprocating mechanism 48 for driving the two annular plates 42 to move up and down synchronously. The working principle and usage process of this invention are as follows: Before using the fermenter, heating medium is introduced into the jacket space formed by the tank body 1 and the outer shell 8 through the inlet pipe 9 on the outer shell 8, and then discharged through the outlet pipe 10. The precise temperature control of the fermentation environment inside the tank body 1 is achieved through the medium circulation. After the temperature inside the tank stabilizes, the Astragalus fermentation raw material is transported through the liquid inlet pipe 5 and introduced into the inlet pipe of the float plate 2 through the telescopic pipe 7, and finally enters the inside of the tank body 1. At this time, the float plate 2 can be suspended on the liquid surface by the buoyancy of the fermentation liquid. Since the telescopic pipe 7 can adaptively extend and retract with the position of the float plate 2, leakage of fermentation liquid or invasion of miscellaneous bacteria is avoided during the feeding process. Since the upper connecting frame 31 is connected to the float plate 2 through the linkage 36, it can slide along the drive shaft 35 with the float plate 2. Therefore, it can adaptively adjust its height according to the changes in liquid level caused by feeding, evaporation and other working conditions, and always maintain the optimal stirring depth below the liquid level. When mixing at low speed, the servo motor fixed at the bottom of the tank 1 can drive the drive shaft 35 to rotate. When the drive shaft 35 rotates, it can drive the lower connecting frame 31 to rotate synchronously. When the lower connecting frame 31 rotates, with the cooperation of the transmission rod 33 and the connecting block 34, it can drive the upper connecting frame 31 to rotate. When the two connecting frames 31 rotate, the mixing plates 32 on both sides can form a shearing and pushing effect on the fermentation liquid, which can promote the full contact between the effective components of Astragalus membranaceus and probiotics, and improve the uniformity and efficiency of fermentation. During fermentation, bubbles generated by microbial metabolism and swelling of Astragalus raw materials will accumulate on the liquid surface. At this time, after the reciprocating mechanism 48 is started, it can drive two annular plates 42 to move up and down synchronously along the guide seat 41. When the annular plate 42 moves, the impact plate 47 on its surface will hit the guide seat 41 and generate vibration. At this time, the elastic strip 43 inside the annular plate 42 will vibrate with the movement of the annular plate 42. Therefore, when the elastic strip 43 vibrates, the bubbles on the liquid surface can be removed. In addition, the float plate 2 is always suspended on the liquid surface, so that the bubble removal component 4 can be kept above the liquid surface and accurately act on the bubble accumulation area to achieve stable bubble breaking under fluctuating working conditions. After fermentation is complete, stop the drive shaft 35 and the reciprocating mechanism 48. At this time, open the two valves on the drain pipe 6 to discharge the fermentation products. During cleaning, the cleaning liquid can be introduced through the inlet pipe 5 and the stirring assembly 3 can be started to achieve all-round cleaning inside the tank. The cleaning wastewater is discharged through the drain pipe 6, thus completing the entire fermentation cycle. In addition, this fermenter adopts an integrated architecture of "PLC core control + sensor feedback + actuator linkage", focusing on the key process parameters of Astragalus compound probiotic fermentation such as temperature, liquid level, stirring speed, defoaming frequency, and internal pressure, to achieve automated and precise control and safety protection. As for the structure such as exhaust pipe and inspection port, its function and connection method are conventional existing technologies in the field of fermenters, and such structures are not shown in the attached drawings.
[0021] like Figure 2 , Figure 4 and Figure 6As shown, in some embodiments, the reciprocating mechanism 48 includes a housing 481 fixed inside the tank 1. Two auxiliary rotating rods 482 are rotatably connected inside the housing 481 via bearings. A T-shaped reciprocating rod 483 is movably connected to the top of each auxiliary rotating rod 482. One end of each T-shaped reciprocating rod 483 slides through the housing 481 to its exterior and is fixed to a limiting rail 484. A sliding groove in the limiting rail 484 contains a sliding rod 485 that is slidably connected to it. Two connecting rods 486 are rotatably connected to one side wall of each moving rod 485 via bearings. The other end of each connecting rod 486 is rotatably connected to a corresponding annular plate 42 via bearings. Two devices for limiting the movement of the T-shaped reciprocating rods 483 are fixed inside the housing 481. Guide block 487 and T-shaped reciprocating rod 483 slide on the corresponding guide block 487 respectively. The main rotating rod 488 is rotatably connected to the inside of the housing 481 through bearings. The surface of the main rotating rod 488 is fixed with a driving gear 489. The surfaces of the two auxiliary rotating rods 482 are fixed with driven gears 4810. The driven gears 4810 are meshed with the driving gears 489. When in use, the rotation of the main rotating rod 488 will drive the driving gear 489 fixed on its surface to rotate synchronously. Since the driven gears 4810 on the surfaces of the two auxiliary rotating rods 482 are meshed with the driving gears 489, the driving gears 489 can drive the two auxiliary rotating rods 482 to rotate synchronously at the same speed and in the same direction, so as to realize the equal distribution and synchronous transmission of power. Since the top of the auxiliary rotating rod 482 is movably connected to the T-shaped reciprocating rod 483, when the auxiliary rotating rod 482 rotates, the movable connection point at its top will make a circular motion. Through mechanical force, the T-shaped reciprocating rod 483 can be pushed to make a horizontal reciprocating motion along the limiting direction of the guide block 487. Since one end of the T-shaped reciprocating rod 483 extends to the outside of the housing 481 and is fixed with the limiting rail 484, the horizontal reciprocating motion of the T-shaped reciprocating rod 483 will drive the limiting rail 484 to move horizontally in sync. Since the moving rod 485 limits... The sliding connection is located in the sliding groove of the limiting rail 484. Therefore, when the limiting rail 484 moves horizontally, it can drive the moving rod 485 to move horizontally synchronously. When the moving rod 485 moves, it can drive the two annular plates 42 to slide up and down synchronously along the guide seat 41 in cooperation with the connecting rod 486. Therefore, the annular plates 42 and the elastic strip 43 can be vibrated. At this time, since the moving rod 485 can slide up and down on the limiting rail 484, it will not be interfered with when it moves up and down with the float 2.
[0022] like Figure 6As shown, in some embodiments, a drive shaft 4811 adapted to the drive shaft 35 is rotatably connected inside the housing 481 via bearings. The bottom end of the drive shaft 4811 is inserted into a slot opened at the top of the drive shaft 35. A cathode electromagnetic plate 4812 is fixed to the top end of the drive shaft 4811, and an anode electromagnetic plate 4813 is fixed to the bottom end of the main rotating rod 488. The bottom of the cathode electromagnetic plate 4812 and the top of the anode electromagnetic plate 4813 are in contact. The cathode electromagnetic plate 4812 and the anode electromagnetic plate 4813 are energized without... The linear control method ensures that it will not affect the normal use of the device. When the drive shaft 35 rotates, it can drive the transmission shaft 4811 to rotate. After the cathode electromagnetic plate 4812 and the anode electromagnetic plate 4813 are energized, the main rotating rod 488 can be driven to rotate. The reason for adopting this transmission method is that this transmission method has the characteristic of "flexible buffer". When the drive shaft 35 or the main rotating rod 488 generates instantaneous torque impact due to load fluctuation, it can form "overload protection" to prevent the servo motor from burning out due to overload.
[0023] like Figure 7 As shown, in some embodiments, the top of the housing 481 is provided with a ring-shaped ventilation hole 4814 for dissipating heat from the driving gear 489 and the driven gear 4810. The top of the tank 1 is equipped with a dust cover 4815 for protecting the ventilation hole 4814. A filter screen 4816 is installed inside the dust cover 4815. In use, the driving gear 489 and the two driven gears 4810 continuously mesh and rotate. The friction between the gears generates heat. At this time, the heat can be dissipated through the ring-shaped array of ventilation holes 4814. Through the cooperation of the dust cover 4815 and the filter screen 4816, dust and lint in the outside air can be prevented from entering the interior of the housing 481.
[0024] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
