Product Overview
The application of stainless steel powder sintering aerators in the fermentation process has become a key component to improve fermentation efficiency due to its unique physical and chemical properties, and the main advantages and implementation points are as follows:
⚙️ 1. Core technical advantages
Efficient gas-liquid mass transfer
The microporous structure (pore size 0.22–100μm) produces 0.1–2mm ultrafine bubbles, the gas-liquid contact area is increased by more than 300%, and the oxygen dissolution efficiency is increased by 40% compared with the traditional aeration device, which significantly accelerates microbial metabolism
Corrosion resistance and long life
Industrial pure titanium or 316L stainless steel is resistant to strong acid/alkali environments (pH 2–12) of fermentation broth, resistant to biofilm adhesion, and has a service life of up to 10 years
2. Fermentation process adaptability
Precise dissolved oxygen control
Uniform micropores avoid the escape of large bubbles, and achieve stable dissolved oxygen (DO) at ±0.5mg/L to meet the strict oxygen control requirements of antibiotic/vaccine fermentation
Anti-pollution design
The pore penetration rate > 98%, the structure without dead ends prevents bacterial clogging, supports CIP/SIP online cleaning and sterilization, and meets GMP sterility standards
