Abstract

See full text

A method and system for reducing the unfermentable solids content in a protein portion, via a counter current wash, at the back end of a corn dry milling process for making alcohol is disclosed. The method can include separating the whole stillage byproduct into an insoluble solids portion and a stillage (centrate) portion, which includes protein. Thereafter, the stillage portion can be separated into a water soluble solids portion and a protein portion. The protein portion may be mixed with clean water to wash and dilute the protein portion. The diluted protein portion may be dewatered to form a dewatered protein portion and a centrate. A portion of the centrate may be used as a protein counter current wash when the protein portion is being separated from the stillage portion. The protein counter current wash reduces the amount of unfermentable solids in the protein portion and the centrate.
