Abstract
Description
Technical Field
[0001] This application relates to the field of fermenter technology, and in particular to a fermenter sidewall interface module with aseptic sampling function. Background Technology
[0002] When performing aseptic sampling in fermenters, a fermenter sidewall interface module with aseptic sampling function is often used. This device, installed on the sidewall of the fermenter, allows for sample extraction without affecting the aseptic environment inside the tank. It ensures the aseptic nature of the sampling process, preventing contamination by other microorganisms from affecting the accuracy of fermentation results and product quality. At the same time, it facilitates real-time sample acquisition for testing and analysis during fermentation, helping to accurately control the fermentation process, optimize process parameters, and thus improve fermentation production efficiency and product quality, providing a strong guarantee for the stability and reliability of fermentation production.
[0003] For fermenters with aseptic sampling function, first ensure that the environment inside the fermenter is sterile, then perform aseptic sampling through the side wall interface module. During the sampling process, the interface module must be kept sealed and sterile. Finally, the extracted samples are processed or analyzed.
[0004] In existing technologies, some fermenter sidewall interface modules with aseptic sampling functions often employ simple valve or pipe connection structures. When sampling the fermentation broth, these interfaces are highly susceptible to introducing external bacteria, leading to contamination of the fermentation system and severely impacting product quality and production efficiency. Although some devices utilize sealed sampling structures, frequent opening and sampling operations still pose a risk of contamination from the external environment. Furthermore, existing sampling structures cannot achieve complete aseptic processing and cannot effectively sterilize the interface after sampling, failing to guarantee a sterile environment for subsequent fermentation. Therefore, a fermenter sidewall interface module with aseptic sampling function is proposed to address these issues. Utility Model Content

[0040] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0041] Example: Fermenter sidewall interface module with aseptic sampling function, refer to Figure 1 , Figure 3 and Figure 4 The system includes a tank 1, which can hold fermentation materials and provide a relatively enclosed space to prevent the intrusion of external impurities and microorganisms. A feed inlet 2 is fixedly connected to the right side of the tank 1 for adding raw materials, nutrients or inoculum. A valve 3 is fixedly connected to the outside of the feed inlet 2 to control the opening and closing of the material flow. A stirring mechanism 4 is installed inside the tank 1 to fully mix the materials in the fermentation liquid, promote the contact between microorganisms and nutrients, and improve fermentation efficiency and quality. A sampling mechanism 5 is installed on the left side of the tank 1 to achieve aseptic sampling of materials during the fermentation process and avoid contamination of the tank environment.
[0042] Specifically, the tank 1 can hold fermentation materials and form a closed space to prevent the intrusion of miscellaneous bacteria. The right side of the tank 1 is connected to the feed inlet 2, and there is a valve 3 outside to control the flow of materials. The inside is equipped with a stirring mechanism 4 to promote the mixing of fermentation liquid materials and improve fermentation efficiency and quality. The left side of the outside is equipped with a sampling mechanism 5, which can take samples aseptically to prevent contamination of the tank environment.
[0043] The stirring mechanism 4 includes a housing 41, which is a protective shell for the stirring mechanism 4, used to protect the internal drive component 42 and prevent contamination. The drive component 42 is arranged in the space area inside the housing 41, which is the power source of the stirring mechanism 4. It consists of a motor 421, a drive shaft 422 and a rotating shaft 423. The drive end of the drive component 42 is fixedly connected to a stirring plate 43. During the rotation of the stirring plate 43, it can generate strong convection and shearing action on the material in the tank 1, promote the uniform mixing of the material, and allow microorganisms, nutrients and oxygen to fully contact in the tank, providing good conditions for the fermentation process. A connecting block 44 is fixedly connected to the outer side of the stirring plate 43, which transmits the rotational motion of the stirring plate 43 to the follower rod 45, so that the follower rod 45 can move with the rotation of the stirring plate 43, thereby realizing the synchronous movement of the scraper 46.
[0044] Specifically, the stirring mechanism 4 uses the outer shell 41 as a protective shell to protect the internal drive component 42 and prevent contamination.

[0048] Specifically, the sampling mechanism 5 includes a sampling interface tube 51, which serves as a channel between the inside of the tank 1 and the sampling mechanism 5, allowing the material inside the tank to be discharged to the sterile sampling bottle 58. The sampling interface tube 51 is connected to a flow reversing valve body 52 on its outer left side. When sampling is required, the valve core is rotated to the "sampling" position to connect the sampling interface tube 51 with the sterile sampling bottle 58. When sampling is not required, the valve core is rotated to the "closed" position to cut off the pipeline connection, thereby ensuring the sealing of the inside of the tank 1.
