Ethanol Production Dry versus Wet Grind Processing

The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further. The mash is then cooled and mixed with more enzymes to convert the remaining sugar polymers to glucose before fermenting to ethanol (Murthy, et al., 2006).
