Disk stack separator, centrifuge types

In those cases where the particles are small and/or the viscosity of the fluid is high, filtration is not very effective. In such cases, centrifugation is the most common and effective method for separating microorganisms, cells, and precipitates from the fermentation broth. Two major types of centrifuge - the tubular-bowl and the disk-stack - are used for continuous, large-scale operation. 

Two major types of centrifugal separators are used in press-type oil/fat extractions and wet rendering horizontal decanters and vertical stacked conical disk centrifuges. A drawing of a... 

Centrifugal partition chromatography (CPC), a type of CCC that uses discrete partition cells inside a rotor, was used by Renault et al. (1997) to separate anthocyanins from black currant and grape skins. They used two instmments from Sanki Engineering Ltd (Kyoto, Japan) a laboratory model LLB-M and a pilot-scale model LLI-7, both fitted with a stacked disks type rotor.
