Abstract
A method and system are disclosed for producing a protein and fiber feed product from a whole stillage byproduct produced in a corn dry milling process for making alcohol, such as ethanol, and/or other biofuels/biochemicals. In one embodiment, the method includes separating the whole stillage byproduct into an insoluble solids portion and a centrate (solubles) portion. Thereafter, a fine fiber and protein portion may be separated from the centrate (solubles) portion. The fine fiber and protein portion may be dewatered to provide a protein and fiber feed product. In one example, the protein and fiber feed product can include insoluble solids, such as wet or dry distiller's grains with or without solubles. The resulting protein and fiber feed product may be sold and/or used as rumen feed, swine feed, chicken feed, aqua feed, food uses, or have other uses, including pharmaceutical and/or chemical usage, for example.
