ICM INC - Ethanol Production Process

Ethanol is commercially produced using either a wet mill or dry mill process. Wet milling involves separating the grain kernel into its component parts (germ, fiber, protein, and starch) prior to fermentation. ICM-designed plants utilize the dry mill process, where the entire grain kernel is ground into flour. The starch in the flour.

ADM considers calling time on ethanol mills as oil fall bites

Feb 8, 2016 . The plants are “dry mills”, relatively simple factories that grind corn kernels and send the starch to a refinery for distillation into ethanol. ADM's “wet mills”, which can make a broader menu of products including ethanol and high-fructose corn syrup, are not part of the study. Mr Luciano told analysts he was.
