Skrobia i białka
Białka
Od koncentratów białkowych po izolaty — nasze technologie ekstrakcji, oddzielania, oczyszczania, zagęszczania i suszenia pomagają opracować proces idealnie dopasowany do danego celu, bez względu na to, czy chodzi o paszę zwierzęcą czy dodatek do pokarmów i napojów dla ludzi.
Białka
Technologia oddzielania od GEA zapewnia wysoki poziom odzyskiwania wysokiej jakości produktu, a nasze wirówki dekantacyjne i odśrodkowe zaprojektowano z myślą o maksymalnej skuteczności oddzielania, optymalnym uzysku białka, minimalnym zużyciu energii oraz higienicznym procesie. Ponadto GEA oferuje szereg suszarek rozpyłowych, które można skonfigurować do obsługi proszków o szerokim spektrum właściwości.
Poza koncentratami białek roślinnych oraz izolatami roślinnymi oferujemy pełne rozwiązania dla hydrolizowanego białka rybnego i białek zwierzęcych, w tym żelatyn.
GEA has developed a comprehensive range of technologies, equipment and know-how to configure and install equipment for key process steps in vegetable protein manufacturing.
Key process steps for plant-based protein powders
-
1
The most common wet separation is a multi-stage process involving protein extraction, protein precipitation and purification. Key end points are consistent protein quality and high yields, using technologies that ensure hygienic processing and sustainable water management. A membrane filtration unit could optionally be used to isolate specific fractions of the purified protein.
-
2
The protein-rich fraction derived from the isolation and purification steps is neutralized and diluted to the required concentration and viscosity.
-
3
An indirect UHT plant with tube heat exchanger, steam injection or steam infusion is used to carry out effective heat treatment of protein dispersions.
-
4
The dryer is configured to match the final protein powder properties. The configuration can vary from single stage to three stage drying, with or without fines recycling, integrated agglomeration and/or lecithination.
-
5
Flash and ring dryers are used for starch and fiber streams drying. Wet material is dispersed into a stream of heated air, which conveys it through a drying column. The heat from the air stream dries the material as it is conveyed.
-
6
Conveying of powder from the dryer to powder storage followed by conveying to the powder filling system or other processing unit such as powder mixing. Conveying can be performed by gravity, pneumatic, mechanical or vibratory means as required by the application.
-
7
Powder filling into 25kg and big bags using high hygiene automatic powder fillers. Automated bag handling and closing is performed inside an enclosed safe environment to eliminate potential for contamination.
-
8
Effluent from the protein isolation process can undergo thermal separation in an evaporator, to produce a concentrate and a clean condensate. Condensate from the evaporator can be further purified in a GEA reverse osmosis (RO) plant to generate a concentrated retentate and a permeate of very high purity.

Effective CIP solutions remove any leftover product from the plant, tank surfaces, heat exchangers, pumps, pipes, etc. Systems with SIP (Sterilize-in-Place) functionality for high microbiologic control can be integrated.
