Claim:
1. A method for front end separation of an oil by-product from grains used in an alcohol production process, the method comprising: grinding the grains into grain particles to release oil from the grains; mixing the grain particles with a liquid to form a slurry including starch, fiber, protein, germ, and the released oil defining free oil in the slurry; subjecting the slurry to liquefaction to provide a liquefied starch solution including sugars and the fiber, protein, germ, and free oil; separating solids including the fiber and germ from the liquefied starch solution including the free oil and sugars; thereafter and prior to fermentation, separating the free oil from the liquefied starch solution to yield the oil by-product; and after separating the free oil from the liquefied starch solution, rejoining the liquefied starch solution including the sugars with the separated solids, then subjecting the mixture to fermentation to produce alcohol.
