Protein extraction at the highest level

Flottweg decanters, Sedicanter® and belt presses are the optimal solution for extracting proteins from various raw materials. Our separation systems isolate valuable proteins and their plant-based by-products. We offer the right industrial centrifuge for all process steps − extraction, precipitation, washing, concentration and clarification. The aim is to obtain a large quantity of high quality protein from the plants.

The process of protein extraction
Regardless of the process, the first step in protein recovery is the extraction of the protein. The protein is extracted from the ground raw material in a multi-stage process. In the next step, coagulation, the protein is precipitated from the solution and separated. Depending on requirements, the precipitated protein content can be increased with additional washing steps. Thus, protein concentrates or even high-purity protein isolates can be produced.

The resulting protein exhibits maximum nativity, excellent functionality and can then be fed directly to spray drying or processed directly in the undried state. To achieve an optimal protein yield, it is also possible to recover additional non-functional protein by means of thermal precipitation.

The separated high-fiber plant components are then mechanically dewatered using the Flottweg belt press and finally dried.
