Minnesota ethanol plants mainly use the dry milling method for ethanol production. In dry milling, corn is ground into meal. Water is added to the meal, turning it into "mash" followed by the addition of enzymes, which converts the starch to simple sugars. Ammonia is added to control pH and as a fuel source for yeast. This preps the mash ...
