    GrindingCooking and LiquefactionSaccharificationFermentationDistillation and Increase of Ethanol ConcentrationFor dry grinding corn, a hammermill or roller mill is used to do the grinding. Figure 7.11 is a schematic of a hammermill with corn being put through it. The hammers are attached to rods that turn on a rotor. As the rotor turns, the feed (corn in this case) is hammered against the wall. A screen at the bottom allows particles that are small enough to leave the unit and keeps in the larger particles to continue to be hammered until all the material is in the correct size range.

  • Ethanol fuel Wikipedia

    Ethanol fuel is ethyl alcohol, the same type of alcohol found in alcoholic beverages, used as fuel.It is most often used as a motor fuel, mainly as a biofuel additive for gasoline.The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat.Ethanol is commonly made from biomass such as corn or sugarcane.

  • Ethanol Production United Petroleum

    Ethanol consumes more energy during production than it produces. Petroleum distillates have a negative energy balance. Petrol delivers 23% less energy than is required to produce it! Ethanol on the other hand has a positive energy balance. On average, ethanol delivers 67% more energy than it takes to produce it (USDA). Ethanol damages car engines.

  • Liquefaction Novozymes

    Liquefaction is the second step in the ethanol fuel production process, between grinding and saccharification. In this step, mash from corn or other starches is first cooked down to a gravy-like substance. Then, the liquefaction process begins with partial hydrolysis to lower its viscosity. This thinning process is helped along with enzymes
