In general, ethanol is not the primary focus for wet milling processors. The corn dry-milling process is a less versatile, less capital-intensive process that focuses primarily on the production of grain ethanol. In this process, the corn kernels are hammer milled into a medium-to-fine grind meal for adding to the ethanol production process.
Ethanol production, purification, and analysis techniques
Starchy materials are converted to ethanol by two major processes, dry milling and wet milling. 2.2.1 Dry milling Dry milling the dominant and more efficient ethanol production process than wet milling. It produces about 2.8 gallons of ethanol per bushel of corn (Rendleman and Shapouri, 2007). The schematic of dry milling is shown below (Figure 1).
Production of Corn Ethanol Corn-Based Ethanol
Dry milling is the first method of producing corn based ethanol. First, the starch is ground from the corn kernel into a dry, powdery meal. The meal is mixed with water to create a wet mash. Enzymes are added to the mash, converting it into dextrose. Ammonia is put in to feed the yeast that will be added later. The mash is then cooked at a high
