Abstract

Technical Field
[0001] This utility model relates to the field of Bacillus coagulans fermentation technology, and in particular to a Bacillus coagulans fermentation device. Background Technology
[0002] Bacillus coagulans is a Gram-positive bacillus with rod-shaped cells that are blunt at both ends. The cells are arranged singly or in pairs and contain spores. The spores are elliptical and located in the center or near the end of the cell. The cysts do not swell. It is a facultative anaerobe and has the characteristics of acid and heat resistance. It can survive in an environment with a pH of 2.0-7.5. It can still maintain a certain level of activity after being treated at 80℃ for 10 minutes. The optimal growth temperature is 37℃-45℃.
[0003] In the prior art, during Bacillus coagulans fermentation, some devices cannot maintain the temperature required for fermentation. Inappropriate temperature leads to changes in the microbial metabolic pathway and the production of abnormal metabolites. Therefore, a Bacillus coagulans fermentation device is proposed.

[0029] This utility model has the following beneficial effects:
[0030] 1. In this invention, the water level inside the outer shell drops, causing the suspended ball to fall as well. This causes the connecting rod, along with the fixing block and the retaining ball, to rotate downwards under the action of the rotating shaft. Therefore, the retaining ball does not block the small hole inside the retaining block. Under the continuous action of the pump, water from the tank is transferred to the interior of the outer shell through the outlet pipe and the outlet valve, causing the water level to rise. As the water level rises, the suspended ball floats upwards, driving the connecting rod, fixing block, and retaining ball to rotate synchronously under the action of the rotating shaft, causing the retaining ball to block the small hole inside the retaining block. This structure ensures that Bacillus coagulans maintains the temperature required for fermentation throughout the fermentation process, solving the problem in some devices where unsuitable temperatures lead to altered microbial metabolic pathways and the production of abnormal metabolic products.
[0031] 2. In this invention, a starting motor drives the drive shaft to rotate, which in turn drives the connecting ring and the inclined plate stirring rod to rotate synchronously. Because the inclined plate stirring rod is tilted, the angle between it and the fluid during rotation causes the fluid to flow at different speeds on the surface of the rod, thus creating shear force within the fluid. Compared to flat plates or other stirring rods, the shear force generated by the inclined plate stirring rod is more effective at breaking large bubbles into smaller ones. These smaller bubbles have a larger specific surface area and are more likely to rise to the liquid surface and be punctured by bubbles under buoyancy. This structure reduces the number of bubbles generated during the fermentation process of Bacillus coagulans, solving the problem of reduced fermentation quality caused by excessive bubbles in some devices.

[0041] Reference Figures 1 to 6 This utility model provides an embodiment of a Bacillus coagulans fermentation device, comprising a support plate 1, which serves as the basic support structure for the entire Bacillus coagulans fermentation device, providing a stable mounting surface for components such as the water tank 2 and the outer shell 14, ensuring the device remains stable during operation and preventing shaking or tilting from affecting the fermentation effect. A water tank 2 is fixedly connected to the top of the support plate 1, used to store water or other liquid raw materials required during fermentation, providing the necessary liquid environment for fermentation.

A water outlet pipe 3 is fixedly connected to the inner wall of the water tank 2, connecting to the water tank 2 and serving as the channel for the liquid to flow out of the water tank 2, transporting the liquid in the water tank 2 to the required location to meet the liquid requirements during fermentation. A water outlet valve 4 is fixedly connected to the outside of the water outlet pipe 3, with water outlet holes 5 opened on the inner wall of the water outlet valve 4. These holes are the specific channels for the liquid to flow out of the water outlet valve 4, and their size and number affect the liquid flow rate and velocity.

The locking ball 11 interacts with the outlet valve 4. According to the swing position of the connecting rod 9, the locking ball 11 can lock or release the outlet valve 4, thereby realizing automatic control of the outlet valve 4 and adjusting the water output of the water tank 2. A suspension ball 12 is fixedly connected to the other end of the connecting rod 9. A water inlet pipe 27 is fixedly connected to the outside of the water tank 2.
[0042] Thermometers 13 are fixedly connected to the front exterior of both the water tank 2 and the outer shell 14 to monitor the temperature inside the water tank 2 and fermentation cylinder 15 in real time. The outer shell 14 is fixedly connected to the top of the support plate 1, and the fermentation cylinder 15 is fixedly connected inside the outer shell 14. A cover plate 31 is fixedly connected to the top of the fermentation cylinder 15 to seal it. A steam outlet pipe 16 is fixedly connected to the top of the cover plate 31, and a feed pipe 18 is fixedly connected to the other end of the cover plate 31 away from the steam outlet pipe 16 for adding coagulant Bacillus to the fermentation cylinder 15. A rotating cover 17 is fixedly connected to the top of the feed pipe 18 and the top of the steam outlet pipe 16. A stirring assembly providing rotation capability is provided on the top of the cover plate 31. The stirring assembly includes a motor 19, a drive shaft 20, multiple connecting rings 21, and inclined plate stirring rods 22. The bottom of the motor 19 is fixedly connected to the top of the cover plate 31. The outside of the drive shaft 20 is fixedly connected to the output end of the motor 19. The inner walls of the multiple connecting rings 21 are fixedly connected to the outside of the drive shaft 20. Multiple inclined plate stirring rods 22 are fixedly connected to the outside of the multiple connecting rings 21.
[0043] Multiple air bubble spikes 23 are fixedly connected to the bottom of the cover plate 31. A discharge pipe 24 is fixedly connected to the bottom of the fermentation cylinder 15. A rotating cover 25 is fixedly connected to the outside of the discharge pipe 24. Multiple rotating covers 28 are installed inside the water tank 2. A water outlet pipe 26 is fixedly connected to the bottom of the support plate 1. An electronic valve is fixedly connected to the outside of the water outlet pipe 26. The end of the water outlet pipe 26 furthest from the electronic valve is fixedly connected to the inner wall of the water tank 2. A pump 29 is fixedly connected to the bottom of the support plate 1, providing power for the liquid flow in the water outlet pipe 26. The outside of the water outlet pipe 26 is connected to the output end of the pump 29. Two sets of feet 30 are fixedly connected to the bottom of the support plate 1, providing support for the entire fermentation device.
[0044] Working principle: First, add water matching the fermentation temperature to the inside of the outer shell 14. Open the rotating cover 17 on the outside of the steam outlet pipe 16 and the feed pipe 18, and transfer the Bacillus coagulans to the inside of the fermentation tank 15 through the feed pipe 18. Start the motor 19 to drive the drive shaft 20 to rotate. The drive shaft 20 drives the connecting ring 21 and the inclined plate stirring rod 22 to rotate synchronously. Since the inclined plate stirring rod 22 is inclined, its presence makes the shear force distribution in the fluid more uniform during the stirring process. Appropriate shear force can break bubbles into smaller bubbles, making it relatively difficult for small bubbles to coalesce. At the same time, the change in the flow field near the inclined plate stirring rod 22 also interferes with the movement trajectory of the bubbles, reducing the chance of collision and coalescence between bubbles, allowing the bubbles to rise to the liquid surface quickly with a smaller size, making them easier to break by the bubble piercing 23.
[0045] Turn off motor 19 to stop stirring, let it stand for fermentation, add water to the inside of water tank 2 through water pipe 27, and turn on the power so that rotating cover 3 28 opens, heating the water inside water tank 2 until it reaches the appropriate temperature for fermentation, and then use it for later use.
[0046] The internal water temperature is observed through the thermometer 13 on the outside of the outer casing 14. When the temperature does not meet the fermentation requirements, the electronic valve opens, allowing the water inside the outer casing 14 to be slowly transferred through the discharge pipe 24 to the water outlet pipe 26 until it reaches the water tank 2, forming a water cycle and achieving water conservation. At the same time, as the water level inside the outer casing 14 drops, the suspended ball 12 also falls, causing the connecting rod 9, along with the fixing block 10 and the retaining ball 11, to rotate downwards under the action of the rotating shaft 8. Therefore, the retaining ball 11 does not block the small hole inside the retaining block 6. Under the continuous action of pump 29, the water inside water tank 2 is transferred to the inside of outer shell 14 through water outlet pipe 3 and water outlet valve 4. The water level begins to rise. When the water level rises, under the upward floating action of suspension ball 12, it drives connecting rod 9, fixing block 10 and locking ball 11 to rotate synchronously under the action of rotating shaft 8, so that locking ball 11 blocks the small hole inside locking block 6, thereby achieving the purpose of shutting off water transmission. When the coagulant Bacillus in fermentation tank 15 has finished fermenting, rotating cover 25 is opened, so that the coagulant Bacillus falls into the receiving bucket prepared in advance by the personnel under the action of gravity.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
