Fermenter

Our stainless steel fermenter system, crafted from medical-grade SUS316L stainless steel, is designed to meet the rigorous demands of modern biopharmaceutical manufacturing—from antibiotic and vaccine production to high-density microbial fermentation. This system adheres to GMP, cGMP, EudraLex, and FDA 21 CFR Part 11 standards, ensuring seamless cross-border sales without regulatory hurdles. The contact surfaces undergo electropolishing to Ra ≤ 0.4 μm, eliminating dead zones and minimizing adsorption, thus preventing microbial growth and contamination.

The fermenter offers outstanding biocompatibility, meeting USP Class VI criteria, with no leachables or heavy metal residues, making it ideal for sensitive drugs such as antibiotics and vaccines. It supports in situ sterilization (SIP) at 121°C and 0.3 MPa pressure, achieving a Sterility Assurance Level (SAL) of 10⁻⁶, essential for sterile production environments. With full traceability, all batch data including material sources, sterilization processes, and production parameters are recorded in real-time, meeting audit trail requirements.

Featuring a customizable volume range from 10L to 20,000L, this system caters to all stages from lab research to large-scale industrial production. An integrated CIP system ensures 100% cleaning efficiency through automated procedures, drastically reducing batch transition times. The magnetic coupling agitator design eliminates leakage risks while offering options like Rushton, anchor, or helical ribbon impellers tailored to different fermentation systems.

With low-shear mixing technology (tip speed ≤1.2 m/s), it minimizes cell damage and enhances survival rates during microbial cultures. An efficient aeration system featuring ring distributors and microbubble diffusers achieves a kLa value of 150 h⁻¹, crucial for high-density fermentations. A dual-loop temperature control system (jacket + coil) maintains temperatures within ±0.1°C accuracy, suitable for thermosensitive microorganisms like yeast.

Real-time monitoring of multiple parameters (pH, DO, ORP, sugar concentration, and pressure) ensures process stability, while integrated ports for sterile feeding, sampling, and defoaming support complex processes like fed-batch and continuous fermentation.

CFD-optimized designs ensure mixing uniformity >98% and batch-to-batch purity consistency CV <3%, enhancing product quality. Smart PID controls automatically adjust pH, DO, and temperature, keeping process fluctuations within ±2%, improving yield by over 30% compared to traditional fermenters. Defoaming systems combine mechanical and chemical methods to prevent oxygen transfer issues and overflow risks.

An open-frame structure facilitates easy maintenance, with sensors and valves easily accessible, resulting in equipment availability exceeding 99%. Designed for long-term use, this system can last over 15 years, offering significant cost advantages with energy-saving technologies that reduce power consumption by 25%. Its modular design allows for capacity expansion and functionality upgrades, adapting to growing business needs.

This versatile fermenter is suitable for bacterial (E. coli, Bacillus subtilis), fungal (penicillin, Aspergillus), and yeast fermentations, covering a wide array of applications including antibiotics, vitamins, amino acids, vaccines, and probiotics. It meets the bulk procurement needs of pharmaceutical companies, biotech firms, and vaccine manufacturers, especially for large-scale commercial production exceeding 500 tons/year. Custom branding and certification marks enhance product recognition and brand value.

Safety features include automatic alarms and shutdowns for abnormal conditions (over-temperature, over-pressure, low liquid level), explosion-proof design (Ex d IIB T4) for flammable environments, and remote monitoring capabilities that support cross-facility process coordination.
