9.9.7 Corn Wet Milling
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.

The capacity of the ball-milling cylinder and excessively long 28-d generation time constrain the amount of aged TWPs that can be produced through conventional milling. In contrast, cryo-milling reduces the particle size of TWPs at the rate of −275.0 μm/d, which is nine times higher than that upon dry- and wet-milling.
