Biotech fermentation centrifuge for continuous solids discharge
Ensure high-density fermentation processes achieve optimal solids separation and concentration, addressing the challenges of maintaining consistent discharge in varying feed conditions.

Separates and Concentrates Biotech Slurries
The BTUX from Alfa Laval is a vortex nozzle centrifuge designed to tackle challenging biotech separation duties, specifically in high-density fermentation and cell culture applications. Utilizing self-regulating vortex nozzles, it maintains constant solid concentrations despite fluctuations, enhancing separation efficiency. This centrifuge supports the production of recombinant proteins, monoclonal antibodies, and vaccine components. Operating continuously and automatically, the BTUX efficiently processes slurries with solids content ranging from 1–20% by volume. It integrates seamlessly with your production line, featuring a CIP system for automated cleaning and designed for steam sterilization to meet stringent NIH guidelines for BSL-2. The BTUX offers flexible configurations to meet varying process requirements, including corrosion-resistant materials for chemical applications, while minimizing energy consumption through its closed system and low-pressure operations.
