Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment for microbial fermentation, specifically a feeding device for a microbial fermenter. Background Technology
[0002] Microbial fermentation refers to the process by which microorganisms, under suitable conditions, transform raw materials into products needed by humans through specific metabolic pathways. The production level of microbial fermentation mainly depends on the genetic characteristics of the microbial strain and the culture conditions. Microbial fermentation processes are classified into aerobic and anaerobic fermentation based on fermentation requirements. Aerobic fermentation methods include liquid surface culture fermentation, fermentation on porous or granular solid culture media, and aerated submerged fermentation. Anaerobic fermentation uses aeration-free submerged fermentation. Therefore, both aerobic and anaerobic fermentation can be achieved through submerged culture, which is completed in a cylindrical fermenter with a specific diameter-to-height ratio. Currently, fermentation engineering is applied in the pharmaceutical, food, energy, chemical, and agricultural industries: plant gene modification; biological nitrogen fixation; engineered insecticidal biopesticides; microbial nutrients; and environmental protection. During microbial fermentation, as the metabolic waste of microorganisms increases, it is necessary to continuously replenish nutrients in the fermenter so that the microorganisms can continue to survive and divide. This process is called feeding. Some existing feeding devices cannot guarantee the uniformity of nutrient solution mixing, which is not conducive to replenishing nutrients for microorganisms.
[0003] While the feeding device for a microbial fermenter disclosed in patent application CN 207918806 U ensures sufficient filling of the space during feeding and avoids backflow through unidirectional feeding, effectively reducing contamination of the microorganisms in the fermenter by airborne pathogens and pollutants and improving the safety of microbial fermentation, it does not solve the existing problem of difficulty in ensuring the uniformity of nutrient solution mixing. Therefore, we propose a feeding device for microbial fermenters. Utility Model Content

A second sealing ring 9 is fixedly disposed inside the mounting bracket 8, and a feed pipe 10 is fixedly disposed outside the mounting bracket 8 above the feeder 7 to facilitate auxiliary feeding.
[0025] In this embodiment, preferably, the feeding tank 11 is fixedly installed at the end of the feeding pipe 10 away from the fermenter body 1. A second sealing cover 12 is movably installed above the feeding tank 11, and a third sealing ring 13 is fixedly installed below the second sealing cover 12. An inner viewing window 14 is fixedly installed below the second sealing cover 12 on the outside of the feeding tank 11. Several second support frames 15 are fixedly installed below the feeding tank 11 to facilitate the storage of nutrient mixture.
[0026] In this embodiment, preferably, the stirring motor 16 is fixedly installed above the second sealing cover 12, and a first mounting box 17 is fixedly installed between the stirring motor 16 and the second sealing cover 12. Two synchronous gears 18 are fixedly installed inside the second sealing cover 12 below the stirring motor 16, and a stirring frame 19 is fixedly installed below the synchronous gears 18 to facilitate stirring of the nutrient mixture and thus ensure uniform mixing.
[0027] In this embodiment, preferably, the feed pump 20 is fixedly installed above the second sealing cover 12 on the side near the feed pipe 10. A second mounting box 21 is fixedly installed on the outside of the feed pump 20. Inside the second mounting box 21, the feed pump 20 is fixedly installed on the outside of the mounting frame 22. A connecting pipe 23 is fixedly installed inside the feed tank 11 below the feed pump 20 to facilitate the delivery of nutrient solution.
[0028] In this embodiment, a feeding device for a microbial fermenter is used such that the operator places the microbial culture medium inside the fermenter body 1, seals the fermenter body 1 with the first sealing cap 3, inserts the feeder 7 into the inlet 5, and fixes the feeder 7 by engaging the feeder 8 with the thread on the outside of the inlet 5. The feeder 7 is secured by the thread on the outside of the inlet 5 with the mounting bracket 8. The mounting bracket 8 and the inner side of the sealing cap are provided with a second sealing ring 9 and a first sealing ring 4, respectively, to ensure a tight seal. The other end of the feeding pipe 10 is connected to the feed pump 20 on the feeding tank 11 to supply... The feed pump 20 draws nutrient solution from the feed tank 11 through the connecting pipe 23, and then delivers it into the fermenter body 1 through the feed pipe 10 and the feeder 7, facilitating the replenishment of nutrients for the microorganisms. Simultaneously, the feed tank 11 is equipped with a stirring rack 19, which, driven by the stirring motor 16, effectively mixes the nutrient solution inside the feed tank 11, ensuring that the nutrient solution delivered to the fermenter body 1 provides better nutrition for the microorganisms. During sterilization, the feed pump 20 can extract hot steam, which is then used to sterilize the feed tank. The feed pipe 10 and the fermenter body 1 are heat-sterilized. The advantages of this feeding device for a microbial fermenter are that it draws feed from the feeding tank 11 via a feed pump 20, and then delivers it to the fermenter body 1 through the feeding pipe 10 and feeder 7. The feeding tank 11 is equipped with a stirring motor 16, which drives a stirring frame 19 to rotate via two synchronous gears 18. This stirring frame 19 agitates the nutrient solution inside the feeding tank 11, ensuring a uniform mixing of various nutrients and guaranteeing that the nutrient solution provides better nutrition for the microorganisms. Another advantage of this feeding device for a microbial fermenter is that the device ensures the sealing of the connections between various components through the setting of a first sealing ring 4, a second sealing ring 9, and a third sealing ring 13. This effectively prevents bacteria in the air from entering the fermenter body 1 and contaminating the microorganisms inside. When sterilizing, the device can use the feed pump 20 to draw hot steam, which will enter the fermenter body 1 through the feed pipe 10 and the feeder 7. The hot steam is used to sterilize the various components, making the operation relatively convenient.
