Amido e proteine
Proteine
Le nostre tecnologie di estrazione, separazione, purificazione, concentrazione ed essiccazione per proteine concentrate e isolate consentono di progettare il processo ottimale per ogni applicazione, che si tratti di mangimi animali o di integratori da utilizzare nelle bevande e nell’alimentazione umana.
Proteine
La tecnologia di separazione di GEA assicura elevati livelli di recupero di un prodotto di massima qualità con centrifughe decanter e separatori centrifughi progettati per la massima efficienza di separazione, un tenore proteico ottimale, il minimo consumo di energia e una gestione igienica dei processi. Inoltre GEA offre un’ampia gamma di spray dryer che possono essere configurati per adeguarsi a una vasta serie di caratteristiche delle polveri.
Oltre che per proteine vegetali concentrate e isolate, offriamo anche soluzioni complete per proteine animali e del pesce idrolizzate, incluse le gelatine.
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.
