Wet Milling vs Dry Milling: The Differences, Advantages
Dry milling typically uses particle-on-particle contact to reduce materials' size, while wet milling involves dispersing the material in a liquid and using solid, grinding elements to reduce size. Products can be broken down through either one of these processes, but wet milling, which we'll discuss first, tends to be a more intensive ...

to the absence of the germ separation stage after initial grinding [5]. One possible strategy to improve oil recovery from the dry-grind process is to shift more oil distribution to the thin stillage (liquid fraction). The oil separation from the liquid phase is much easier, and it can be achieved by using existing centrifuges or decanters.
