FLOTTWEG SEDICANTER® Discover New Potentials

DISCOVER NEW POTENTIALS Flottweg Sedicanter® for Processing Fine and Pasty Products The Flottweg Sedicanter® is an innovative solid bowl centrifuge (decanter centrifuge) which combines the advantages of decanter centrifuges and disk stack centrifuges alike. The centrifugal force of the Sedicanter® is between 5000 and 10,000 x g. Its clarification effi- ciency is thus similar to that of a disk stack centrifuge. At the same The Sedicanter® is appropriate for processing soft products such as biomass, yeast suspen- sions, protein suspensions, fermentation broth, time its construction design allows...

APPLICATION AREAS OF THE FLOTTWEG SEDICANTER® Overview Feeds solids concentration in % Vol. 100 mm Flottweg Decanter TECHNICAL INFO Flottweg Sedicanter® Flottweg Disk Stack Centrifuge 0,1 m Comparison of application areas for Sedicanters®, decanters and disc stack centrifuges depending on particle size and solids concentration in the feed Advantages of the Flottweg Sedicanter® • Efficient separation of suspensions for which decanter centrifuges or disk stack centrifuges provide only insufficient results • Processing of suspensions with fine and pasty solids or fluid sediments (yeast, protein,...

APPLICATION AREAS OF THE FLOTTWEG SEDICANTER® Overview of applications and examples The Sedicanter® has turned out to be the best solution compared to tration fine and soft solids from suspensions. Flottweg Sedicanters® watered. That means that the energy efficiency are reliably used in the following applications: INDUSTRIAL BIOTECHNOLOGY Efficient separation of biomass from fermentation broth is one of the focus applications of the Sedicanter®. It is used in industrial biotechnology for the production of vitamins and enzymes, for example. Soy and protein yields can be increased. Especially in...

In the production of plant or animal proteins the Sedicanter efficiently ® separates the coalgulated protein, helping to increase the protein yield. BEER RECOVERY Haven’t found your application? We look forward to your request. Together with our customers we develop new optimization possibilities in different The Sedicanter® efficiently thickens surplus yeast generated in the brewing process, creating two valuable products: The recovered beer can be reintroduced into the brewing process and the yeast can be used for further processing in the food industry, in the dietary supplement industry,...

HOW THE SEDICANTER® WORKS A Unique Conception The functional principle of the Flottweg Sedican- generated by rotation. The conveyor scroll rotates at a slightly different centrifuge. Distinctive features of this kind of cen- The entire centrifuge rotor consists of a bowl shell, a scroll, and a ter is similar to that of a solid bowl decanter ® trifuge are a solid wall bowl and a conveyer scroll located within the bowl. The centrifugal force is speed from that of the bowl and thus conveys the separated solids. rotating gear, which generates the differential speed. HOW THE SEDICANTER® WORKS IN DETAIL...

Example: Beer recovery, high dry substance content in the separated yeast liquids discharge under pressure solids discharge SEPARATION OF THE LIQUID / CENTRATE Using an impeller disk located at the end of the clarification zone, the clarified liquid is discharged from the ma- chine under pressure 5 . By adjusting the impeller, the liquid level in the bowl can be regulated 6 , which in turn changes the hydrostatic pressure on the solids. This means that the cake dryness of the discharged solids and the ® = registered trademark for various countries purity of the centrate can be adjusted from outside...

THE SEDICANTER® IN A NUTSHELL Advantages HIGH CLARIFICATION EFFICIENCY Machine design in compliance with hygienic design thanks to BOWL MATERIAL • Product-wetted weldings, hygienic design (optional) • All surfaces are appropriately treated (optimal surface roughness). • Flushing devices in the housing and in the scroll body • Electro-polished surfaces for scroll, housing, and bowl (optional) ADJUSTABLE IMPELLER • Improves the cleaning effect of the centrifuge bowl • FREQUENCY DRIVEN DRIVES For CIP cleaning at low rotating speed ® = registered trademark for various countries • High centrifugal...

Optimum adjustment to specific characteristics High solids content of the product and the process: thanks to: • Strong compression by centrifugal force • Hydrostatic pressure on the solids ADJUSTABLE IMPELLER • Adjustable during operation • Torque dependent and stepless regulation of the bowl and differential speed • These machine parameters permit the automatic control of the Sedicanter® on request.
