The present invention includes a method for producing ethanol from grain. The method includes: Steeping the corn kernels in tepid water, free of sulfurous acid, in a steeping reactor for 16-20 hours, soaking with recycled enzyme; Milling the soaked corn kernels to separate the germ and soft starch to form a starch-gluten-fiber particle; Extracting the germ in a cyclone reactor; separating the starch to produce a sugar/protein fermentative media; washing the fiber to produce extractables and cellulose products; liquefying in a high speed homogenizer to separate the gluten and fiber to form a starch gel; Fermenting the starch gel to form ethanol and gluten; centrifuging to produce a protein concentrate and yeast cream; and Distilling the ethanol to make beverage, industrial or fuel grade ethanol |
