  • Feeding Corn Milling Byproducts to Feedlot Cattle

    The ethanol is distilled off after the fermentation process. The solution exiting the still is called distillers solubles not to be confused with dry milling distillers solubles. Wet milling distillers solubles contains very little corn residue almost no fat and is high in protein from the remnants of yeast cells from the fermentation process.

    It can be done by dry milling or wet milling. Figures 7.10a and 7.10b show the process steps for each wet and dry milling. For wet milling the corn kernels are broken down into starch fiber corn germ and protein by heating in sulfurous acid solution for 2 days. The starch is separated and can produce ethanol corn syrup or food grade starch.

  • What Happened to the Profitability of Ethanol Production

    Scott Irwin • The ethanol industry has been much in the news in recent months with the ongoing political battle over the future of the RFS. It is easy to lose track of what is actually going on with the ethanol industry itself in this environment. Ethanol production profits were quite strong over 2013-14 moderated over 2015-2016 and appeared to take a further dip in 2017.
