A Future Protein Source – Thanks to Separation

The de-oiled flakes are mashed in stirring tanks, then taken to a Flottweg Decanter, which separates fibers and proteins. The liquid phase containing bitter compounds, carbohydrates, sugar and other soluble flavoring materials is discarded in the waste water.

Protein Separation Up–Close

The solid phase, however, is pumped into another thank. There, its pH value is increased to render the proteins soluble. From there, the mash is put into another Flottweg Decanter to separate insoluble fibers from the solid phase out of the mixture.

These are later used in the animal fodder industry. The clear phase is placed acidified in a final tank. Since the remaining dry substance is only a small volume, the proteins can be separated well using a Flottweg Sedicanter.

Great Task for a Small Unit

To process particularly soft sediments such as lupine protein, Flottweg produces a special decanter centrifuge. The patented Sedicanter can get optimum results with this type of processing: Where a standard decanter achieves a maximum centrifugal acceleration of 6000 g, the Sedicanter, at 10,000 g, breaks through to values that have heretofore only been possible with disk stack centrifuges.

"We decided on the Sedicanter as it combines the advantages of a disk stack centrifuges with those of a decanter. Thanks to its high speed, this machine gets outstanding separation results while simultaneously processing large quantities of solids," explains Marc Zillmann, Head of Production and Product Development at Prolupin.
