Abstract:
1. A method for recovering oil in a dry milling process for producing ethanol from corn, the method comprising: separating a whole stillage byproduct of the dry milling process with a separator into a distillers wet grains fraction, a thin stillage fraction, and an oily fraction; combining the oily and thin stillage fractions; evaporating the combined fractions of the oily fraction and the thin stillage fraction to remove moisture and form a concentrate of the oily and thin stillage fractions; recovering oil from the concentrate with an additional separator; evaporating the concentrate to further reduce the moisture content of the concentrate and form an evaporated concentrate; and mixing the evaporated concentrate with the further reduced moisture content with the distillers wet grains fraction.
