Plant-based protein source
Intake of whole dehulled pulses/grains, flour or concentrates
1
Raw material intake
Intake of whole dehulled pulses or grains, flour, protein concentrate, or other raw material.
Wet grinding or dispersing
2
Wet grinding or dispersing
After intake, the whole pulses or grains are wet ground using a two-stage grinding system. If flour or concentrate is fed, the product is dispersed using a dispersion system to properly mix the product with water.
Solid/liquid separation
3
Solubilized protein separation
A decanter centrifuge separates solids from liquids in a suspension. In a first step, starch and fiber are removed from solubilised protein, in a second stage the precipitated proteins are separated from the remaining liquid.
Isoelectric precipitation (IEP)/ultrafiltration
4
Isoelectric precipitation (IEP)/ Ultrafiltration
Isoelectric precipitation is used to separate and purify protein based on their isoelectric points. This is the pH at which a protein has no net electrical charge and is least soluble in water. This process step is done using a decanter. As an alternative process, we offer also membrane filtration technology to separate the proteins. This technology processes protein without denaturation or loss of properties of the native ingredients.
Washing and de-watering
5
Washing and dewatering
The protein slurry is purified using a clarifier. Impurities and unwanted substances are removed by flushing with fresh water. Simultaneously, the product is dewatered.
Drying
6
Drying
The protein slurry is dried in the spray dryer by rapid evaporation of the liquid with hot air. The remaining powder is the desired protein isolate.
Bagging
7
Bagging
The protein isolates are pneumatically conveyed and packed into big bags.
