Dry Fractionation/ Air Classification
Efficient and Eco-Friendly Protein Separation
Dry fractionation is a mechanical process that separates the different components of grains, seeds, or legumes without the need for chemicals or water. This method is highly efficient and environmentally friendly, making it an ideal solution for producing high-quality protein concentrates.
