2008 National dry mill corn ethanol survey SpringerLink
The 2001 survey included 17 dry and wet mill plants. Since the 2001 survey there has been a rapid expansion of the dry mill corn ethanol market (see graph of plant population in Fig. 1). As of December 2008, there were 42.2 billion liters of installed ethanol dry mill capacity and 35.2 billion liters of operating dry mill capacity in the US.The dry-mill process is less complex than the wet-mill process. Dry milling cooks and ferments ground corn, using enzymes and yeast to produce ethanol and carbon dioxide. Once the starch is converted to an alcohol, the leftover stillage is turned into distiller’s grains. Dry-mill plants are generally smaller and require less capital invest-of Agriculture Ethanol Co-Product Use in U.S. Cattle

ECONOMIC AND TECHNICAL ANALYSIS OF ETHANOL
produced at a lower cost and more efficiently in a dry mill plant than in a wet mill plant, under current economic conditions. Of the more than 70 US ethanol plants currently in production, only a few are of the wet mill variety. A descriptive engineering spreadsheet model (DM model) was developed to model the dry mill ethanol production There is a considerable variation in production capacity in both dry and wet mills (Table 2). Average scale of dry mills is 52.7 million gallons per year (MMGY) and that for wet mills is 145.9 MMGY (Table 2). A bushel of corn in 2006 generates 2.81 gallons of denatured ethanol in a dry mill and 2.74 gallons in a wet mill. The highest yields fromAnalysis of the Efficiency of the U.S. Ethanol Industry

New USDA Report Offers Fresh Insights into Ethanol and Co
This is important because dry mills tend to use less thermal energy and electricity than wet mills. Dry mill ethanol producers are fully drying only 53% of distillers grains production (i.e., to 10% moisture), while 32% of distillers grains are marketed in wet form and 11% are modified wet distillers grains (i.e., they receive minimal drying).It typically contains 21% protein, 2.5% fat, and 8% fiber. On average, 508 million pounds per month of dried corn gluten feed was produced from the corn wet mill processes in the U.S. during the April 2007 through December 2008 time period. Dried corn gluten feed accounts for 33% of the total quantity of corn wet mill process byproducts.Recent Trends in U.S. Wet and Dry Corn Milling Production

What Are the Differences between Dry and Wet
The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less Corn wet milling and dry milling are the predominant methods of processing corn and each method produces distinct co-products. Consequently the ethanol yield from a dry grind / dry fractionation process is negatively impacted as the result of fermentable starch exiting the process with the co-products. 1497 Shoup Mill Rd Corn Milling: Wet vs. Dry Milling AMG Engineering

Dry mills are less capital intensive but produce less valued byprod-ucts than wet mills. Conversely, profitability in the current wet-milling industry is enhanced by the revenues generated by byproducts.

Ethanol: Recent Trends in U.S. Operational Efficiency AgFax
After peaking at 2.98 in March 2020, the ethanol conversion rate declined to 2.84 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 There is a considerable variation in production capacity in both dry and wet mills (Table 2). Average scale of dry mills is 52.7 million gallons per year (MMGY) and that for wet mills is 145.9 MMGY (Table 2).

THE 2001 NET ENERGY BALANCE OF CORN-ETHANOL
The energy used to convert corn to ethanol is based on a U.S. survey conducted in 2001 by BBI International. On the average, dry mill ethanol plants used 1.09 Kwh of electricity and about 34,700 Btu of thermal energy (LHV) per gallon of ethanol. When energy losses to produce electricity and natural gas were taken into account, the average Wet Milling Process Wet mills are typically larger than dry mills and can produce corn sweeteners as well as etha-nol. The wet milling process is very complex and produces a variety of products and by-prod-ucts. Corn is steeped for 30 to 40 hours to begin the process of breaking the kernel down into its components.
