Title: Corn fractionation method

Abstract: An improved method for processing corn into ethanol and other valuable co-products. The invention generally involves a multi-step process which produces germ (or oil), protein, and feed yeast as its co-products while maintaining or enhancing the provision of fermentable sugar to ethanol fermentation. This is accomplished by fundamentally altering the way the corn is fractionated, disrupting the cell walls rather than the protein matrix as is done in conventional wet milling.
