- Maximum yield and purity - high efficient separation solutions for bacterial cultures
- Premium German engineering with hygienic design and 24/7 automated operation
- From lab to production scale - Efficient solutions for bacterial separation
Produce high-quality thickeners, biopolymers, vitamins and many other products economically
Industrial Centrifuges for Efficient Bacterial Separation in Fermentation ProcessesBacterial cultures such as E. coli or Bacillus subtilis are used in the fermentation process to produce, for example, thickeners (such as xanthan and gelan), biopolymers or vitamins. Advanced industrial centrifuges can be used to extract these fermentation products from the fermentation broth (downstream processing).
Customized solutions
Flottweg is the only supplier of industrial centrifuges whose product portfolio includes decanters, Sedicanter® and disc separators which feature discontinuous and continuous discharge. Flottweg always has the optimal separation solution, adapted to the customer's requirements and process.
Hygienic design
Our machines for the biotechnology sector all feature hygienic design and can be easily integrated into existing, fully automated CIP processes.
Competent support
In addition to the premium quality of our separation solutions, we support our customers with in-depth consulting and laboratory tests. This is followed by pilot tests through which the machine is precisely configured with commissioning and process optimization at the customer's site and integration into the overall plant.

The process of separating biomass after fermentation
After fermentation, the Sedicanter® or separator separates the bacteria from the fermentation solution. The aim is to thoroughly dewater the biomass in order to achieve the highest possible yield of active ingredients. The Flottweg Sedicanter® achieves high dry content in biomass. The Flottweg separator clarifies the separated fermentation broth either directly or possibly in a second step after the Sedicanter®, so that the purest possible liquid is available for further process steps. This usually contains the actual recyclable material, from which biopolymers, thickeners or vitamins are produced.
This is how biomass separation is achieved using Sedicanter® and separators from Flottweg
Customer benefits
Customized solutions for high product quality
Depending on the customer product and process, different bacteria are used. E. coli or Bacillus-subtilis bacterial cultures are frequently used. This results in products such as vitamins, biopolymers and thickeners. For high product quality, after fermentation it is crucial to obtain a liquid that is as pure as possible for further processing. Therefore, the processed bacterial cultures must be efficiently separated from the fermentation broth. Cell separation, also known as downstream processing, is performed by Flottweg centrifuges. They mechanically separate the recyclable material from the fermentation broth. For the highest possible purity of the liquid, it is important that the centrifuge is precisely designed for the respective process. With our decanters, Sedicanter®, separators and nozzle separators, we have the right solution for every process. Work together with our biotechnology experts, to fine-tune the details and optimize operating parameters for the best separation results and a high product quality.
- Different industrial centrifuges for different fermentation processes.
- Customized solutions for high product quality.
- Competent support and optimization for the best separation results.
High-performance industrial centrifuges Made in Germany
Our centrifuges for processing bacterial cultures meet the highest quality standards. All our machines are developed and manufactured exclusively in Germany. Hygienic design and CIP cleaning are standard features in biotech centrifuges. On request, this can be done fully automatically and without disassembly thanks to the closed system. Depending on customer requirements and processes, our decanters, Sedicanter® and separators are also available in explosion-proof, nitrogen-inerted versions. Numerous special features make our industrial centrifuges powerful, robust and ideal for 24/7 operation.
- Powerful Sedicanter®, separators and nozzle separators.
- Made in Germany for high machine quality.
- Hygienic design for use in the biotechnology and food industries.
- All parts in contact with the product are made of high-quality stainless steel (corrosion and acid-resistant).
- Explosion-proof, inerted version available for flammable solvents.
Maximize Yield while Reducing Operating Costs
Thanks to Flottweg Sedicanter® and separators, you always achieve the optimal dry matter content (TS content). The drier the separated biomass, the more recyclable material is retained for further processing. For you, this means: lower product losses and a higher yield. At the same time, the maintenance-optimized design of our centrifuges facilitates servicing and shortens downtimes. Maintenance requirements are also lower because the machine uses few wear parts and those are of high quality. This in turn means less downtime and therefore lower operating costs. Our machines can be easily integrated into existing, fully automated processes. Thanks to automation and the Ingo operating concept, 24/7 operation is trouble-free and possible with little effort.
- High recyclable material yield thanks to optimal selectivity.
- Maintenance-optimized design reduces maintenance costs.
- Reduced maintenance requirements for minimized downtime.
- Easy to use thanks to fully automatic solutions.
- 24/7 operation is possible.
