Protein production
from grasses and leaves

Full utilization of agricultural raw materials

Industrial centrifuges for the production of high-quality protein from grasses & leaves.

Sustainability also means getting the most out of raw materials. Valuable plant protein can be obtained from grasses, leaves and agricultural waste. In agriculture, the main focus is often on vegetables or fruit. The remaining leaves are often considered waste. However, these plant components can also be used further. The extracted protein is then suitable for further processing, for example in animal feed.


Fully automated process line

For the process of protein extraction from grass and leaves, Flottweg supplies the core, the so-called wet fractionation. Our process solutions range from single units with manual controls to fully automated lines.


High quality protein

A protein with high purity and functionality is produced thanks to Flottweg decanter centrifuges. This means that the protein can be used for a wide variety of purposes. The remaining plant components can also be efficiently dewatered, making them suitable, for example, for producing animal feed or for incineration in biogas plants. 


Holistic use of raw materials

With a Flottweg solution for protein recovery from grasses and leaves, you can get the most out of your raw materials. In this way you act sustainably and at the same time have gained another valuable resource.

Our machines for protein extraction from grasses & leaves with production capacities from 200 kg (441 lbs) /hour

The principle for the extraction of vegetable protein from grasses and leaves

Extraction is the first step of a multi-step process, where protein from the grasses and leaves is extracted from the shredded plant residues. 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. This makes possible the production of protein concentrates or even high-purity protein isolates.

The resulting protein exhibits maximum nativity and excellent functionality and can then be directly fed into the spray drying process. 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.

Customer benefits

Highly functional plant-based protein.

The multi-stage extraction process and the high separation capability of Flottweg decanter centrifuges make it possible to produce a high-protein content that is highly functional. Highly functional proteins are important so many diverse end products can be produced from plant protein. Flottweg decanter centrifuges and Sedicanter® can be used to extract valuable protein from vegetable waste and thus open new sales markets.

  • Highly functional plant-based protein.
  • High protein purity
  • High protein yield

Powerful industrial centrifuges "made in Germany"

Our decanter centrifuges and Sedicanter® are used to extract protein from lentils, beans and peas. Flottweg is the world's only manufacturer of the Sedicanter®. The Flottweg Sedicanter® combines the advantages of a decanter centrifuge and a separator, providing the perfect technical solution for the demanding task of separating plant protein. Both the decanter and the Sedicanter® are constructed in accordance with the hygienic design guidelines of the food industry for the production of protein. To ensure optimal quality and performance, all our machines are developed and manufactured exclusively in Germany. Equipped with the adjustable impeller and the Simp Drive® drive concept, our robust and flexible industrial centrifuges are ideal for the production of proteins from grasses and leaves.

  • Worldwide, Flottweg is the only manufacturer of the Sedicanter®
  • Very robust and highly flexible.
