Efficient separation technology: Flottweg sets new standards at ACHEMA

Industrial centrifuges for efficient separation of biomass in fermentation processes

Downstream processing is a crucial step in industrial biotechnology. Advanced industrial centrifuges can be used to extract these fermentation products from the fermentation broth (downstream processing). In biotechnological processes, the decanter centrifuge is very often a key technology for separating microorganisms from fermentation broths.

The Flottweg Sedicanter^®, which combines the benefits of a decanter and separator, is suitable for fermentation-derived products. Featuring a unique design, the Sedicanter^® has been specially developed for soft, flowable solids. The objective is to dewater the biomass efficiently and achieve the maximum yield – even with fluctuating infeed volumes. With a centrifugal field of 5,000 to 10,000g, the Sedicanter® provides high clarification performance and an optimum separation rate.
In a possible second process step, the fermentation broth is clarified by a Flottweg AC series separator in order to separate the remaining solids. Depending on the final product, the focus is either on yielding a highly dewatered solid or the clarified centrate.

Separation solutions for plant extracts

Manufacturers of plant extracts face two major challenges in their production process: The sensitivity and different composition of the products depends on the season (fresh product or dried product). Many manufacturers also process several products on a single process line. Therefore, it is important that the machines used react flexibly to changing framework conditions. Flottweg decanters, separators, and Sedicanters® continuously separate biomass from liquid as efficiently as possible. Decanters are primarily used in preclarification to obtain a high yield of liquid extract. Flottweg separators then clarify the liquid extract for the purest possible end product.
