Description

Technical Field

[0001] This utility model belongs to the field of probiotic fermentation technology, specifically relating to a probiotic fermentation tank. Background Technology

[0002] A probiotic fermentation tank is a device specifically designed for probiotic fermentation, typically made of stainless steel or plastic. This equipment allows for the control of environmental factors such as temperature, humidity, and oxygen to ensure that probiotics can grow and multiply in a suitable environment.

[0003] During probiotic fermentation, the state inside the fermenter (such as the growth of probiotics, the uniformity of the fermentation broth, and the degree of fermentation) is difficult to observe directly. Traditional methods usually require sampling for testing, but this method has the following problems: insufficient real-time capability: it is impossible to monitor the fermentation state in real time, and the overall situation can only be inferred based on intermittent sample testing. Risk of contamination: sampling may damage the seal of the fermenter, leading to external contamination. To solve the above problems, this invention provides a probiotic fermenter.

To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, and to facilitate a better understanding of this utility model by those skilled in the art, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only some, not all, embodiments of this utility model, and do not constitute a limitation on its rights. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] This embodiment provides a probiotic fermentation tank, including a fermentation tank 1 and a temperature control chamber 2. The temperature control chamber 2 is provided between the inner wall and the outer wall of the fermentation tank 1. A discharge pipe 11 is provided at the bottom of the outer wall of the fermentation tank 1 to discharge the remaining raw materials. A water inlet pipe 10 is provided at the bottom of the outer wall of the fermentation tank 1 and communicates with the temperature control chamber 2. By injecting heated water into the fermentation tank 10, the temperature of the temperature control chamber 2 can be increased. The temperature inside the temperature control chamber 2 can be adjusted by manually introducing water of different temperatures (high temperature or low temperature).

[0027] The fermenter 1 has a water outlet pipe 12 connected to the temperature control chamber 2 on its outer wall near the top, allowing the supplied water to drain. The top flange of the fermenter 1 is connected to a top cover 13, which ensures the airtightness of the fermenter 1. A stirring mechanism 3 is rotatably connected to the center of the bottom of the top cover 13. The stirring mechanism 3 includes a rotating shaft 7 rotatably connected to the bottom of the top cover 13. The outer wall of the rotating shaft 7 has two symmetrically arranged stirring and scraping parts 16 for more uniform stirring. The top of the top cover 13 near the outer edge has a feed pipe 20, an air inlet pipe 21, and a vacuum pump 34. An endoscope 5 is installed through the top cover 13. The endoscope 5 includes two sets of endoscopes. The probiotics in two locations in the fermenter 1 can be observed through the endoscope 5. Direct observation from different locations helps to understand the probiotics. The observations from the two locations can be compared, making it easier to draw conclusions about the probiotics and the fermentation process.

[0028] The air extractor 34 is used to remove air from the fermenter 1, reduce the oxygen content in the fermenter 1, ensure the efficiency and success rate of probiotic fermentation, and also ensure a suitable air pressure during probiotic fermentation.

[0029] The endoscope 8 includes an inlet tube 14, an upper tube 15, a lower tube 19, and an outlet tube 24. The bottom of the upper tube 15 is slidably inserted into the top of the lower tube 19. The tube wall of the upper tube 15 is fixedly inserted into the rotating sleeve 28. The top of the upper tube 15 is connected to the inlet tube 14. An upper plane mirror 33 is inclinedly arranged inside the connection between the inlet tube 14 and the upper tube 15. The bottom of the lower tube 19 is connected to the outlet tube 24. A lower plane mirror 23 parallel to the upper plane mirror 33 is arranged inside the connection between the outlet tube 24 and the lower tube 19. This is to allow the image near the light exit tube 24 to be reflected, reflected by the lower plane mirror 23 to the upper plane mirror 33, and finally reflected out from the light entrance tube 14. The bottom of the upper lens tube 15 is slidably inserted into the top of the lower lens tube 3. A locking knob 30 for fixing and locking the upper lens tube 15 is provided on the outer wall of the top of the lower lens tube 3. The tube wall of the upper lens tube 15 is fixedly inserted into the rotating sleeve 9. The top of the upper lens tube 15 is connected to the light entrance tube 13. An upper plane mirror 20 is inclinedly arranged inside the connection between the light entrance tube 13 and the upper lens tube 15. The bottom of the lower lens tube 3 is connected to the light exit tube 5. A lower plane mirror 23 parallel to the upper plane mirror 20 is arranged inside the connection between the light exit tube 5 and the lower lens tube 3.

[0030] A rotating handle 29 is fixedly installed on the outer wall of the rotating sleeve 28, which makes it easier to rotate the rotating sleeve 28.

[0031] The stirring and cleaning component 16 includes two symmetrically arranged stirring rods 17. This symmetrical arrangement increases motion coordination and ensures effective stirring. The ends of the two stirring rods 17 furthest from the rotation axis 7 are connected to a sidewall cleaning scraper 22. The sidewall cleaning scraper 22 has an inverted triangular structure to enhance its strength, and its outer wall is in close contact with the inner wall of the fermentation tank 1. This design enhances the cleaning effectiveness of the fermentation tank 1.

[0032] The bottom end of the rotating shaft 7 is provided with a strip plate 35. The bottom of the strip plate 35 is in contact with the bottom of the inner wall of the fermenter 1. The left and right ends of the strip plate 35 are respectively fixedly connected to the bottom ends of the opposite sides of the two side wall scraping plates 22. The front and rear sides of the strip plate 35 are provided with bottom wall scraping plates 36. The opposite sides of the two bottom wall scraping plates 36 are both beveled. This design increases its own strength and is used to scrape the bottom of the inner wall of the fermenter 1, preventing the bacteria and culture medium from adhering to the bottom of the inner wall of the fermenter 1.

[0033] A servo motor 4 is provided in the middle of the top of the top cover 13. The end of the output shaft of the servo motor 4 passes through the top of the top cover 13 and is coaxially connected to the top of the rotating shaft 7. The servo motor 4 provides rotational power for the rotating shaft.

[0034] The top of the top cover 13 and the position outside the servo motor 4 are provided with a protective cover 6, which provides protection for the servo motor 4.

[0035] The top of the feed pipe 20 is threaded with a first sealing cap, and the air inlet pipe 21 is equipped with a one-way valve 9.

The inlet end of the light inlet tube 14 is fixedly fitted with a light inlet lens 32, and the outlet end of the light outlet tube 24 is fixedly fitted with a light outlet lens 26.

[0036] The bottom of fermenter 1, near the outer edge, is provided with four legs arranged in a circular array.

[0037] The probiotic fermentation tank of this invention is used as follows:

[0038] First, hot water at the set temperature is continuously introduced through the inlet pipe 10. After the temperature control chamber 2 reaches the set temperature, the fermentation raw materials are introduced through the feed pipe 20. Then, the servo motor 4 is started, which drives the stirring device 3 to rotate. The raw materials in the fermentation tank 1 are then stirred. After stirring to a certain extent, the servo motor 4 is stopped. Then, the upper endoscope is rotated by turning the handle 29 to rotate the rotating sleeve 28 and adjust the two endoscopes 8 to a suitable angle for comparison and observation to see if the stirring effect is uniform (if production needs are required, the stirring effect can be observed without stopping the servo motor 4). If it is not uniform, the servo motor 4 is started again and stirring continues. After fermentation is completed, the servo motor 4 is stopped, the fermented probiotics are discharged from the discharge pipe 11, and the water in the temperature control chamber 2 is discharged from the water outlet pipe 12.

[0039] The length, position, and thickness of the lines for the servo motor 4 and the temperature control chamber 2 in the attached diagram are for illustrative purposes only, and those skilled in the art can make adaptive adjustments according to actual usage.

[0040] The length, position, and thickness of the lines of the light-incoming lens 32, the light-outgoing lens 26, the upper plane mirror 33, and the lower plane mirror 23 in the attached figures are for illustrative purposes only. Those skilled in the art can make adaptive adjustments according to actual usage.

[0041] The stirring rod 17 and the side wall scraper 22 are conventional settings in the prior art. Those skilled in the art can select appropriate devices or settings based on the above description to achieve "the stirring and scraping component 16 includes two stirring rods 17 arranged symmetrically at the top and bottom, and the ends of the two stirring rods 17 away from the rotating shaft 7 are connected to the side wall scraper 22, which has an inverted triangular structure".

[0042] The servo motor 4 and the rotating shaft 7 are both conventional settings in the prior art. Those skilled in the art can select appropriate devices or settings based on the above description to achieve "the servo motor 4 is provided in the middle of the top of the top cover 13, and the end of the output shaft of the servo motor 4 passes through the top of the top cover 13 and is coaxially connected with the top of the rotating shaft 7".
