A large stainless steel wine fermenter can be used for all kinds of fermentation needs, but the aseptic working environment is the basic requirement, in addition, it is necessary to ensure the independence and directivity of biological strains, and to avoid the derivation of complex bacteria and bacteriophage. What are the design requirements of a large stainless steel wine fermenter?
1. Good mass/heat transfer performance
Excellent material mixing performance in order to provide a better growth temperature of the culture. In the process of animal cell culture, it is necessary not only to mix well but also not to break the animal cells, so as to ensure a smooth fermentation process.
2. Material requirements
The commonly used materials are 316,304,916; the inner surface of a large stainless steel wine fermenter should be smooth and have no dead corner to prevent the deposited material, and it is easy to clean and sterilize after fermentation The material in contact with the culture medium and fermentation liquid must be non-toxic, corrosion-resistant, non-absorbing and non-chemical reaction material.
3. Requirements for the internal and external environment
Active substances are involved in the culture process and must therefore comply with biosafety standards, both to prevent contamination by outside microorganisms and to prevent contamination of the surrounding environment by culture substances in the fermenter. Therefore, a large stainless steel wine fermenter should be a system device with good sealing performance, and its venting, discharging gas, and liquid in the tank should be filtered to remove the active substances.
4. The tank should have a SIP process
The production of a large stainless steel wine fermenter should be up to the standard because the whole biological culture should be carried out under aseptic conditions, that is, aseptic process, aseptic raw material, and aseptic product.
For a large stainless steel wine fermenter to be used safely and aseptically, the manufacturer must comply with these design requirements in order to guarantee the pure flavor of the wine.
