6.3.2 Wet milling. Wet milling of corn is achieved by a combination of chemical and mechanical means. Wet milling begins with steeping of cleaned corn for 30 48 hours with water. Sulfur dioxide is added to the water at the rate of 0.1 0.2% and the solution is heated to about 50 C. This condition prevents growth of putrefying microorganisms.

Nearly 90% of ethanol plants are dry mills due to lower capital costs. Dry milling is a process that grinds corn into flour and ferments it into ethanol with coproducts of distillers grains and carbon dioxide. Wet-mill plants primarily produce corn sweeteners, along with ethanol and several other coproducts (such as corn oil and starch).

DRY MILLING. In dry milling, the entire corn kernel or other starchy grain is first ground into flour, which is referred to in the industry as "meal" and processed without separating out the various component parts of the grain. The meal is slurried with water to form a "mash." Enzymes are added to the mash to convert the starch to dextrose, a ...

Germ Separation After the corn kernels are steeped for softening, they are cracked open to release the germ. The germ contains the valuable corn oil. The germ is separated from the heavier density mixture of starch, hulls and fiber essentially by "floating" the germ segments free of the other substances under closely controlled conditions.
