A dry fractionation method and system provides for generating a protein concentrate product. The method and system includes milling a plant-based flour to generate milled flour and generating a first protein concentrate from the milled flour using a first air classifier. The method and system includes processing the first protein concentrate to generate a protein rich curd and generating a neutral hydrolyzed protein slurry by mixing the protein curd with a base, water and enzymatic cocktail. The method and system includes generating a homogenized protein slurry from the neutral hydrolyzed protein slurry, generating a pasteurized protein slurry by pasteurizing the homogenized protein slurry, and generating a cooled protein slurry by cooling the pasteurized protein slurry. The method and system also provides for extracting the protein concentrate product from the cooled protein slurry.
