  • Method for recovering and producing ethanol and oil
    Patent number: 8722372
    Abstract: To provide a method for producing an ethanol which facilitates the processing of a solid component as a residue generated upon processing, while improving the recovery rate of heat energy contained in leftover food. The method for recovering and producing ethanol and oil is a method for producing ethanol by saccharification, fermentation, and distillation of leftover food. In this method, a three-phase centrifuge for performing separation into three phases of an oil component, an aqueous solution component, and a solid component is used in a step of solid-liquid separation of any one of a saccharified liquid, a fermented liquid, and a distillation waste liquid.
