9.9.7 Corn Wet Milling - US EPA

The overall corn wet milling process consists of numerous steps or stages, as shown schematically in Figure 9.9.7-2. Shelled corn is delivered to the wet milling plant primarily by rail and truck and is unloaded into a receiving pit. The corn is then elevated to temporary storage bins and scale hoppers for weighing and sampling.

Fractionation of transgenic corn seed by dry and wet ...

For wet milling, approximately 60% of each was recovered in three fractions accounting for 20-25% of the total kernel mass. The rCIalpha1s in the dry-milled germ-rich fractions were enriched three to six times compared with the whole corn kernel, whereas the rCIalpha1s were enriched 4-10 times in selected wet-milled fractions.

The first step is to milling the corn. It can be done by dry milling or wet milling. Figures 7.10a and 7.10b show the process steps for each wet and dry milling. For wet milling, the corn kernels are broken down into starch, fiber, corn germ, and protein by heating in the sulfurous acid solution for 2 days.

Wet Milling of Cereal Grains - NALDC

Some of the larger wet-milling plants are equipped with grain driers to dry high-moisture grain. Corn with a mois- ture content under .16 percent can usu- ally be stored safely during the winter, but corn that contains more than 16 percent moisture is turned in the bins periodically. Steeping, or soaking, is the most im- portant step in wet ...
