Ethanol Production - Dry versus Wet Grind Processing —

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind . The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is
