Dry fractionation for plant based protein extraction

A system for generating a protein concentrate product from a plant-based flour, the system comprising:

• a mill generating milled flour from the plant-based flour;
• a first air classifier generating a first protein concentrate and a first starch concentrate from the milled flour, the first starch concentrate being recycled as an input to the first air classifier;
• a processor generating a protein rich curd from the first protein concentrate;
• a mixer generating a neutral hydrolyzed protein slurry from the protein curd, a base, an enzymatic cocktail and water;
• a homogenizer generating a homogenized protein slurry from the neutral hydrolyzed protein slurry;
• a pasteurizer generating a cooled protein slurry from the homogenized protein slurry;
• and
• an extraction device for extracting the protein concentrate from the cooled protein slurry.

A method for generating a protein concentrate product from a plant-based flour, the method comprising:

• decorticating a plant-based source material, the source material having a protein and an oil content therein;
• creating a flour from the source material having the cortex removed therefrom;
• removing at least a portion of the oil content from the flour by generating an ethanol mixture by mixing the flour with ethanol;
• extracting a de-oiled flour from the ethanol mixture;
• milling the de-oiled flour to generate milled flour;
• generating a first protein concentrate from the milled flour using a first air classifier;
• processing the first protein concentrate to generate a protein rich curd;
• generating a neutral hydrolyzed protein slurry by mixing the protein rich curd with a base, an enzymatic cocktail and water;
• generating a homogenized protein slurry from the neutral hydrolyzed protein slurry;
• generating a cooled protein slurry by pasteurizing the homogenized protein slurry;
• and
• extracting the protein concentrate product from the cooled protein slurry.
