Foam is produced when gas is released by a chemical reaction, through continuous aeration, or in transport processes.

The use of chemical anti-foam agents in biotechnology is often not desirable, as these substances remain in the product.

Foamex P provides for foam-free exhaust air, even in fermentations with strong foam formation.

The foam liquid obtained can be diverted or returned to the process, according to the particular process requirements.

Applications

• Food technology
• Biotechnology
• Pharmacy
• On-site foam analyses (field unit)
• Scale-up tests
  

Benefits

• Continuous aeration and optimum volume utilization
• Stabilization of the course of reaction
• Reduction or minimization of use of chemical anti-foam agents
• Media are not “drained away“ with the foam
• Reduced retention time of biocatalysts and/or biomass in the foam
  

Equipment features

• Disassembly without tools for easy cleaning
• Sterilizeable (SIP)
• Suitable for reactors with a total volume of up to 22 L
• Universal interface with pilot reactors
• Driven by magnetic drive
• Speed control and DC motor
• Foam flow rate up to 15 L/min
• Foam humidity up to 25 %
  

Working principle

Foamex P uses centrifugal forces to split the rising foam into a liquid-free gas flow and a liquid flow with clearly reduced gas content.

The latter can be returned to the fermenter or reactor.
