Patent ID: 8227015

Claim:
A grain-based ethanol biorefinery at a single facility comprising: a dry-grind ethanol facility configured to process grain and produce distillers dried grains with solubles; a solvent extraction facility configured to extract crude corn oil from the distillers dried grains with solubles, thereby producing distillers meal, wherein the solvent extraction facility is configured to extract crude corn oil from distillers dried grains with solubles using a hexane extraction process, thereby producing corn distillers meal comprising a crude protein content ranging from approximately 28% to approximately 35% by weight, a crude fat content ranging from approximately 1% to approximately 5% by weight, a neutral detergent fiber content ranging from approximately 25% to approximately 35% by weight, and an acid detergent fiber content ranging from approximately 11.5% to 13.5% by weight.
