Description

Technical Field

[0001] The utility model relates to the technical field of fermentation tanks, in particular to a fermentation tank which is convenient for replacing culture medium. Background Art

[0002] Cell culture is generally carried out in a fermenter. The culture medium is placed horizontally in the fermenter, and then steam is introduced with an agitator to fully heat the equipment for high-temperature sterilization, which is also called full-tank sterilization.

[0003] Since the culture medium is placed horizontally in the fermentation tank and supported by a bracket, and is placed in a matrix shape and fixed, when steam is passed in for sterilization, the steam continuously flows inward from the inner wall and heats the culture medium, causing the edge of the culture medium to be overheated while the inner temperature is insufficient during sterilization, resulting in uneven heating inside and outside, which makes the sterilization of the culture medium incomplete and prolongs the sterilization time to a certain extent.

[0004] Prior art CN112779132A A fully automatic fermentation tank for sterilizing uniform cell culture medium. When steam circulates, it will enter from the air intake mechanism in the gathering device, and then pass into the collecting port. Under the partition of the gathering blocks at the upper and lower ends of the support column, the steam is poured into the air partition plate, and outlets are provided at the upper and lower ends of the connecting pipe, which are horizontally distributed and connected to the bottom of the culture plate, so that the steam is collected through the bracket to the upper and lower sides of the middle of the culture plate, and then discharged from the outlet to heat the inside of the culture medium, thereby ensuring that the inside and outside of the culture medium are heated evenly, thereby solving the above technical problems. In the technical research on improving enzyme activity based on different culture media in 15L or 5L fermentation tanks, the culture medium needs to be replaced, but the above device is not convenient for replacing the culture medium, and cannot automatically detect the pressure in the tank body, which has certain risks; therefore, it does not meet the existing needs. In this regard, we propose a fermentation tank that is easy to replace the culture medium. Utility Model Content
