Methods for producing a high protein corn meal from a whole stillage byproduct and system therefore
First Claim
1. A method for producing a high protein corn meal from a whole stillage byproduct comprising:
- in a corn dry-milling process for making alcohol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion, which includes protein;
prior to any evaporation step, separating the thin stillage portion, via weights, into a protein portion and a water soluble solids portion, wherein the protein portion is not subsequently subjected to an evaporator;
dewatering the protein portion; and
drying the dewatered protein portion via a dryer to define the high protein corn meal that includes at least 40 wt % protein on a dry basis.

Abstract
The present invention relates generally to corn dry-milling, and more specifically, to methods for producing a high protein corn meal from a whole stillage byproduct produced in a corn dry-milling process for making ethanol and a system therefore. In one embodiment, a method for producing a high protein corn meal from a whole stillage byproduct includes, in a corn dry-milling process for making ethanol, separating the whole stillage byproduct into an insoluble solids portion and a thin stillage portion. The thin stillage portion is separated into a protein portion and a water soluble solids portion. Next, the protein portion is dewatered then dried to define a high protein corn meal that includes at least 40 wt % protein on a dry basis.
