Shell: Designed according to industry standards, refined high-quality 304 or 316 stainless steel sanitary shell, high-precision mechanical polishing inside and outside, standard design pressure 10 bar.
Filter element: Adopts excellent performance fiber folded filter element with super large filtration area; also adopts internationally used double O-ring to make the sealing effect more reliable.
Sterilization filter element: Adopts steam-resistant PTFE folded/polytetrafluoroethylene hydrophobic filter element, which can filter bacteria, viruses, and bacteriophages with a filtration accuracy of 0.01um.
Sterilization method: Sterilize with ≤130℃ clean steam once a week, each sterilization time is 30 minutes, which can 100% remove bacteria and various bacteriophages. The sterilization cycle can be determined according to the actual use. If the fermentation production is relatively stable, regular sterilization can be adopted, and the sterilization cycle can be set to one week, one month, or two months. Steam pressure ≤0.02Mpa, the valve must be opened and closed slowly; the sterilization steam must be saturated, and the sterilization process must be supervised by a dedicated person.
