Dry-milling plants have higher yields of ethanol. The wet mill is more versatile, though, because the starch stream, being nearly pure, can be converted into other products (for instance, high-fructose corn syrup (HFCS)). Co-product output from the wet mill is also more valuable. In each process, the corn is cleaned before it enters the mill.
