1. A method for producing a protein and fiber feed product from a whole stillage byproduct produced in a starch containing grain dry milling process for making biofuel and/or a biochemical, the method comprising:
separating the whole stillage byproduct into an insoluble solids portion and a solubles portion, including fine fiber and protein;
filtering out the fine fiber and protein from the separated solubles portion, via a screen with openings, to define a fine fiber and protein portion;
separately dewatering only the fine fiber and protein portion to produce a dewatered protein and fiber feed product; and
recovering the dewatered protein and fiber feed product.
