Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, specifically to a gas-circulating microbial fermentation device. Background Technology

[0002] Important applications of microbial fermentation: Microbial fermentation is a process that uses microorganisms (such as bacteria, fungi, yeast, etc.) to transform organic matter and produce specific products. It has wide applications in many fields such as food, beverage, pharmaceuticals, and bioengineering.

[0003] Traditional microbial fermentation methods often have several shortcomings. For example, in aerobic fermentation, a large amount of sterile air needs to be continuously introduced into the fermenter to ensure that microorganisms have sufficient oxygen for metabolic activities. However, this method may lead to uneven gas distribution, preventing some microorganisms from obtaining enough oxygen, thus affecting fermentation efficiency and product quality. Microbial fermentation is highly sensitive to temperature, with different microbial species having their own suitable temperature ranges for growth. However, during fermentation, the metabolic activities of microorganisms generate heat, causing the temperature of the fermentation system to rise. If temperature control is not timely and effective, it will affect microbial growth and metabolism, thereby reducing product yield and quality. Some existing fermentation devices suffer from insufficient precision and slow response in temperature control, making it difficult to meet the stringent temperature requirements of microbial fermentation. Although some fermentation devices have gas circulation functions, the design of the gas circulation path, circulation speed, and gas-material contact method is not reasonable enough, resulting in low gas circulation efficiency and failing to fully utilize the role of gas circulation in improving fermentation efficiency and promoting microbial growth.

[0014] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0015] 1. This utility model provides a gas-circulating microbial fermentation device. When the chamber is working, if the oxygen concentration inside the chamber is lower than the oxygen concentration required for fermentation, the oxygen generator control panel will turn on the oxygen generator. The oxygen in the oxygen generator will enter the exhaust hole on the exhaust plate through the oxygen generator outlet pipe, and then enter the chamber. When the oxygen concentration inside the chamber reaches the oxygen concentration required for fermentation, the oxygen generator control panel will then control the oxygen generator to turn off, ensuring a constant oxygen concentration inside the chamber and ensuring the oxygen required for microbial respiration.

[0016] 2. The air inside the chamber is drawn out by the air extractor to remove the gases produced by the respiration of microorganisms, causing the air inside the chamber to flow from bottom to top in a state of circulation. This promotes the balance of oxygen concentration inside the chamber, thereby ensuring a good fermentation environment and improving the efficiency of microbial fermentation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Reference Figure 1-4 This utility model discloses a gas-circulating microbial fermentation device, comprising a box body 1. Support bases 5 are fixedly connected to the four corners of the bottom side of the box body 1, avoiding the need to increase the weight of the box body for stability. A sealing door 2 is rotatably connected to the left side of the front surface of the box body 1. A viewing glass 3 is fixedly connected to the center of the sealing door 2, allowing personnel to observe the growth and fermentation of colonies in the culture dishes 13 from the outside. A handle 4 is fixedly connected to the right side of the front surface of the sealing door 2. Fixing plates 7 are fixedly connected to both sides of the inner cavity of the box body 1. A placement plate 11 is provided on the top of the fixing plate 7, and the placement plate 11 has a placement groove 12. The placement groove 12 can hold several culture dishes 13 for microbial fermentation, and the placement groove 12 can stably fix the culture dishes 13, further improving the stability and robustness of the device's placement structure.

[0025] An exhaust plate 16 is provided at the bottom of the inner cavity of the chamber 1. The exhaust plate 16 has several exhaust holes 14 and an electric heating device 15. An air extractor 8 is fixedly connected to the top left side of the chamber 1. One end of the air extractor's air inlet pipe 9 is fixedly connected to the chamber 1, and the other end is fixedly connected to the air extractor 8. A chamber control panel 10 is fixedly connected to the surface of the air extractor 8. The power of the electric heating device 15 can be adjusted through the chamber control panel 10 to control the internal temperature of the chamber 1. At the same time, the air extractor 8 can be turned on and off to remove the gas generated by the respiration of microorganisms in the chamber 1 in a timely manner.

[0026] An oxygen generator 18 is fixedly connected to the bottom right side of the chamber 1. An oxygen generator control panel 17 is fixedly connected to the surface of the oxygen generator 18. One end of the oxygen generator's outlet pipe 19 is fixedly connected to the chamber 1, and the other end is fixedly connected to the exhaust plate 16. An oxygen concentration detector 6 is installed on the upper rear side of the inner cavity of the chamber 1. The oxygen concentration detector 6 detects changes in the oxygen concentration inside the chamber 1 in real time and adjusts the oxygen generator control panel 17 to ensure the oxygen concentration required for microbial fermentation.

[0027] Working principle: The operator places the culture dish 13 containing microorganisms into the placement groove 12 on the placement plate 11, then closes the sealing door 2, opens the control panel 10, and the electric heating device 15 is powered on to heat the inside of the chamber 1. Simultaneously, the operator can view and adjust the temperature through the control panel 10. The oxygen concentration detector 6 located inside the chamber 1 monitors the oxygen concentration in real time and transmits the data to the oxygen generator control panel 17. After processing the data, if the oxygen concentration inside the chamber 1 is lower than the oxygen concentration required for fermentation, the oxygen generator control panel 17 will generate oxygen. When the oxygen generator 18 is turned on, the oxygen inside the oxygen generator 18 enters the exhaust hole 14 on the exhaust plate 16 through the oxygen generator outlet pipe 19, and then enters the interior of the chamber 1. When the oxygen concentration in the chamber 1 reaches the oxygen concentration required for fermentation, the oxygen generator control panel 17 controls the oxygen generator 18 to turn off, thus ensuring a constant oxygen concentration in the chamber 1. The air extractor 8 draws the air from the top of the chamber 1 into the air extractor inlet pipe 9, and then transports the air to the outside of the chamber 1 through the air extractor inlet pipe 9. Throughout the process, the air in the chamber 1 always moves from bottom to top, ensuring a uniform distribution of humidity, temperature, and oxygen in the chamber 1, thereby improving the efficiency of microbial fermentation.
