Ethanol Production - Dry versus Wet Grind Processing

While dry milling is less capital intensive, it also yields less ethanol per bushel of corn than wet milling (Rajagopalan, et al., 2005). Wet milling involves steeping the corn for up to 48 hours to assist in separating the parts of the corn kernel. Processing the slurry separates the germ from the rest of the kernel, which is processed further ...

Corn Milling: Wet vs. Dry Milling - AMG Engineering

These dry fractionation efforts always result in co-products with less purity than those produced by the corn wet milling process. Consequently the ethanol yield from a dry grind / dry fractionation process is negatively impacted as the result of fermentable starch exiting the process with the co-products.

The Ethanol Production Process Process Systems

Jul 12, 2017  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.
