PROTEIN EXTRACTION – GROWTH MARKET AND CHALLENGES Plant-based proteins play an essential role in providing sustainable food for a growing world population. Vegan food has long since outgrown its niche market. However, there are differences: not all plant proteins are equally suitable for use in further processing. Their use is determined by the proteins’ purity, the product yield and the functionality obtained – and along with it, their market value. Flottweg offers you turnkey, automated, efficient process solutions, which enable you to get exactly the protein quality from plant-based raw...

Flottweg assists numerous protein producers all over the world. All of them benefit from a process line that we have planned and set up, or from machines that have been fully custom-made to meet what each company needs or desires. The thing that unites all our projects is highest customer focus and maximized efficiency. Our planning and configurations do not just live up to the “Made in Germany” label, but to our self-image as well. We are a specialist engineering company with seventy years of experience in separation technology and thirty years in protein extraction. We would like to...

SUCCESS IS ... RECOGNIZING AND MAKING USE OF ADVANTAGES Flottweg offers you three different applications or process lines for extracting plant proteins. These are just some of the advantages Flottweg processes offer you in extracting proteins: Production advantages ∙ pecially designed machines and systems for starch and oil crops S ∙ ntegrated downstream processing and upgrading of plant fibers and/or starch I ∙ omplete implementation and individual processes in line with hygienic design C guidelines and automated CIP (Cleaning in Place) ∙ Exceptionally high protein yield and quality...

Prerequisites and factors for Flottweg processes Processing a wide range of raw materials The following crops are suitable for protein recovery by wet fractionation in the Flottweg process: • Starch crops: peas, beans, mung beans, lentils, etc. • Oil crops: soybeans, lupins, sunflowers, canola, etc. Pre-processes The Flottweg application starts after the crops (e.g. peas) have been dehulled and milled. For oil crops, the oils are also extracted before the wet fractionation of protein takes place. Factors which determine quality The product quality of the pure protein obtained is determined...

UP TO THREE UP TO THREE PRODUCT STREAMS PRODUCT STREAMS FOR YOUR PROTEIN FOR YOUR PROTEIN PRODUCTION PRODUCTION In the wet fractionation of starch crops, up to three ingredients in total are separated and processed. The core process is always protein extraction, and from this, one or two further product flows can be obtained. All processes are usually followed by drying the proteins. In individual cases, protein, fiber, and starch are also directly processed in their wet form.

Flottweg's plant protein applications are a win for • the food industry • functional food/food supplement manufacturers • animal feed producers • cosmetics manufacturers and many others. Flottweg offers complete turnkey applications for processing, from approximately 200 kg (440 lb) to 20,000 kg (44,000 lb) of plant meal per hour.

WET FRACTIONATION WET FRACTIONATION OF OIL CROPS OF OIL CROPS In this Flottweg application, two product streams – protein and fiber – are obtained from oil crops like soybeans. Protein extraction The plant meal (alternatively flakes or press cake) is mashed in a water-based solution and extracted in an alkaline environment. As a result of this extraction, the protein is in a liquid form and the fiber remains solid. The liquified protein can be separated from the insoluble fiber using a decanter. The liquified protein is then precipitated and separated in the acidic environment. In an extra...

WET FRACTIONATION WET FRACTIONATION OF STARCH CROPS OF STARCH CROPS In this Flottweg application, three product streams – proteins, starch and fiber – are obtained from plants that contain starch (like peas). The separation of protein and fibers is identical to the wet fractionation of oil crops (page 8). Starch extraction also takes place here. Starch production Firstly, in the extraction step, the insoluble starch and fiber fractions of the plant are separated from the liquified protein. The starch-fiber mixture is then separated into the fiber and starch product streams using centrifugal...
