The decanter centrifuge for soft sedimentThe Flottweg Sedicanter® for processing fine-grained, past-like products.
Flottweg produces a special decanter centrifuge for soft, easy-flowing sediment. The Flottweg Sedicanter® separates solids from liquids. The special thing about it: The solids consist of a soft to easy-flowing sediment.
Soft or easy-flowing solids are difficult to process with a standard decanter. Only the patented Flottweg Sedicanter® achieves an optimal result. Thanks to its adjustable impeller, it achieves the best possible selectivity even with fluctuating feed rates.
The Sedicanter® combines the advantages of disc separators and decanter centrifuges. It clarifies the suspension in a similar way to a separator, i.e. it provides an optimally clarified centrate. At the same time - like the decanter - it takes large quantities of solids at the inlet and produces dry solids (sediment) in the discharge.
Flottweg has been building the Sedicanter® for 20 years. We offer you a wealth of experience and numerous well-known references all over the world. Our Sedicanter® is characterized by outstanding performance, high quality and its long service life.
Typical fields of application of the Flottweg Sedicanter®
How the Flottweg Sedicanter® works
The Flottweg Sedicanter® functions in a similar way to a solid bowl scroll centrifuge (decanter centrifuge). The rotation of the centrifuge generates a centrifugal field. This causes the heavy solid particles to be thrown outwards onto the bowl. The liquid collects inside after the scroll conveyor. The scroll conveyor rotates at a differential speed relative to the bowl. It thus transports the separated solids to the solids discharge of the Sedicanter®.
Due to its design, the Sedicanter® - like the decanter - can process high solids contents in the feed. The difference to a decanter centrifuge lies in the composition of the mixture to be processed. In contrast to a decanter, the Sedicanter® also processes fine-grained, paste-like solids, which are difficult to discharge from a decanter due to their consistency.
The Sedicanter® combines the advantages of decanter and separator. This permits the efficient separation of mixtures where both decanter and separator provide insufficient results. With a centrifugal field of 5,000 to 10,000 g, it has a high clarifying capacity and an optimum separation rate. At the same time it is possible to process mixtures with a large proportion of solids. Thanks to Flottweg's Simp Drive® drive concept and Flottweg's adjustable impeller, fluctuations of the solids in the feed can be easily compensated. This ensures a constant separation result at all times.
- high loads of solids in the inlet
- good compensation for solid material fluctuations in the inlet
- high separation rates and high clarification efficiency
Our Sedicanter® are available in hygienic versions to ensure safe processing of food, pharmaceutical, fine chemical and biotechnological products. All parts in contact with the product can be completely CIP cleaned. In addition, all metallic parts in contact with the product are made from austenitic or austenitic-ferritic stainless steels. Thanks to the special construction of the Sedicanter®, hard-to-clean areas such as gaps and dirt corners are avoided.
- Hygienic design available
- CIP cleaning possible
- Use of high-quality stainless steel
- Special construction that avoids hard to clean areas
Flottweg's adjustable impeller ensures that the system can react quickly during operation to changing conditions in the incoming mixture. Depending on the feed product, the liquid level in the decanter bowl can be changed by means of the adjustable impeller. This always leads to an optimum separation result, even under changing conditions. In addition, the Simp Drive® can be used to control the bowl speed and differential speed as a function of torque. Flexible speed adjustment is especially important when the operating parameters have to be constantly adjusted. This is the only way to achieve high economic efficiency and a constant dry solids content.
Depending on the requirements, the Sedicanter® is available in a hygienic or inerted version. The hygienic design is mainly used in the chemical, pharmaceutical and food industries. An inerted version is necessary if media are processed whose vapors form an explosive mixture with oxygen, e.g. solvents. In an inerted operation, inert gas seals the separation chamber from the ambient air.
- Flexibility in the event of a fluctuating composition of the feed product by means of the adjustable impeller
- Inerted operation or hygienic design is possible
- Torque-dependent and infinitely variable control of the
- bowl and differential speed
The impeller and Simp Drive® can be adjusted during operation thus making both the machine and the system easy to operate. There are various automation possibilities available to achieve exact settings and thus an optimum separation result. At a glance, an overview of all information is provided by the user interface. In this way, the effort required to operate the entire system can be reduced.
- Adaption during operation
- Process automation possible
- All important process parameters at a glance.

The processing of lupines is equally demanding for man and machine. Especially the separation of bitter substances and dietary fibers on an industrial scale posed a great challenge.
