Evaluation of Oil Extraction on Corn Dry-Milling
Dry Milling Process. The first step in the dry milling process is to remove any debris from the corn grain (i.e. corn stalk) using a process of screens (ICM, 2012). The entire grain kernel (fermentable and non-fermentable components) is sent through a hammer mill to be ground into course flour.
