After peaking at in March 2020, the ethanol conversion rate declined to in October 2020. The second operational efficiency measure is the pounds of DDGS produced per bushel of corn processed. Computing the pounds of DDGS produced is complicated by the different types of distillers grains that are produced by dry mill ethanol plants.

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 ...

Corn ethanol is produced by dry or wet milling [13,14]. Ethanol is the main product of the dry milling process while wet milling is more efficiently designed to separate various products and parts of corn for food and industrial uses including corn starch and corn oil, as well as ethanol. In the dry milling process the kernel is ground into ...

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.

Two methods are currently used to produce ethanol from grain: wet milling and dry milling. The adjectives 'wet' and 'dry' describe the method, not the product. The different methods affect both the profitability and logistics. Dry mills produce ethanol, distillers' grain and carbon dioxide (Figure 1). The carbon dioxide is a coproduct of the fermentation, and the distillers' dried ...

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 ...

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.
