Ethanol and starch are the main products generated after the processing of corn via dry grinding and wet milling, respectively. Milling generates byproducts including stover, condensed distillers' solubles, gluten meal, and the dried distillers' grains with solubles (DDGS), which are sources of valuable compounds for industry including lignin, oil, protein, carotenoids, and phenolic compounds.

Summary. Cornstarch is processed to ethanol by either the drygrind or wetmilling process. The two processes differ in how the kernel is initially treated to access starch for enzymatic hydrolysis. In addition to the use of sugar in ethanol production, wetmilled starch can also be sold as dried or modified corn starch, or converted ...

Conventional Corn Starch Ethanol . Ethanol is made both by dry and wet milling of corn. Dry mill plants are designed to process corn into ethanol with Distiller's dried grains and carbon dioxide as the primary coproducts.

Dry mills are usually smaller in size (capacity) and are built primarily to produce only ethanol. Wet mill facilities are called corn refineries, that also produce a list of highvalued coproducts such as highfructose corn syrup (HFCS), dextrose, and glucose syrup. Both wet and dry milling operations convert corn into ethanol [17].

1970's and recent clean air legislation have contributed to an expanded drymill industry. Currently legislative issues are before Congress that could triple the demand for ethanol as an oxygenate component in gasoline. This increased ethanol demand will likely come from the drymilling of corn thereby offering an increased amount of coproducts.

Drymilling 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, highfructose corn syrup (HFCS)).

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 ...
