Biomass Separation
Fermentation Broth

Centrifuge technology for the separation of biomass

Fermentation processes are a central process step in industrial biotechnology. The chemical, pharmaceutical, and food industries rely on fermentation to transform bacteria, yeasts or molds into valuable products and materials.

Mechanical separation technology allows these fermentation products to be obtained from the fermentation broth.


Flottweg offers efficient, reliable, customer-specific processes for obtaining organic acids such as lactic acid, citric acid, and succinic acid, as well as other organic materials.

Our Flottweg Centrifuges are also used to clean nutrient media before their use in fermentation processes. The preparation and clarification of molasses and other sugar solutions is a central part of this process.

Centrifuge Technology for the Separation of Fermentation Products from Fermentation Broth

Flottweg Decanter Centrifuges first separate the biomass from the fermentation broth. Depending on the specific process and fermentation medium, they can achieve a dry substance value (DS) of 20 - 45%. For higher yields, the solid can be mashed again and taken through additional extraction steps.

The Flottweg Separator separates even the finest of solid particles out of the clarified fermentation broth.

To separate extremely fine, soft solids from the fermentation broth, Flottweg developed the Sedicanter®. This machine combines the advantages of the decanter and the separator for separating biomass.
