what is ethanol production process
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.east is added to convert the sugar to ethanol and carbon dioxide. The mash is then allowed to ferment for 50â60 hours, resulting in a mixture that contains about 15% ethanol as well as the solids from the grain and added yeast.
