PROBLEM TO BE SOLVED: To provide a method by which disadvantages of conventional solid fermentation are overcome, to rapidly produce alcohol with high yield and a residue which is useful as animal feed, together with alcoholic fuel, is recovered, when the alcoholic fuel is produced by using biomass as a raw material. SOLUTION: A pulverized or a ground material of the biomass raw material is cooked under the conditions of 60-180°C temperature and 0.06-0.2 MPa pressure, regulated to 60-85% moisture content w.b., and then is quenched down to 25-30°C. Rhizopus oryzae or Koji (rice malt) mold and yeast or Zymonas mobilis are then added, to carry out solid fermentation at 10-33°C. The alcohol produced is separated and recovered, to thereby produce the fuel alcohol. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a container apparatus for fermenting/drying work, in which a time to dry wet organic matter can be shortened much more by fermenting the wet organic matter and the wet organic matter can be dried effectively even when a constitution of the container apparatus for fermenting/drying work is simplified. SOLUTION: The container apparatus for fermenting/drying work is provided with: a square outer frame body 11 which is used for fermenting/drying a granular wet organic matter raw material by using fungi, is opened up and down or opened upward and constitutes an external form of this container apparatus; and a plurality of partition walls 20 arranged erectly in parallel at predetermined intervals so that the space, into which the organic matter raw material is thrown, in the outer frame body 11 is partitioned thereby. The partition wall 20 has partition face materials 21, 21 on both sides thereof and is constituted so that the inside of the partition wall is formed into a hollow shape 25, through which air can pass vertically, and the partition face material 21 is formed into an air-permeable latticed or meshed shape which is formed by making linear parts 21a cross one another.

PROBLEM TO BE SOLVED: To provide a method and an apparatus for producing ethanol by efficiently extracting a sugar content from yacon. SOLUTION: The method for producing the ethanol from the yacon includes a pulverization step for grinding cleaned leaves, stems and root tubers of the yacon by a grinder, a solid-liquid separation step for separating the ground yacon into a sugar-containing filtrate and a solid fibrous material by a solid-liquid separator, a dehydration step for adding water to the solid fibrous material and separating the resultant mixture into a sugar-containing squeezed liquid and a dehydrated cake, a heat sterilization step for heating and sterilizing the filtrate and the squeezed liquid, a fermentation step for obtaining an ethanol raw material liquid by adding an yeast to the sterilized filtrate and squeezed liquid and subjecting the resultant mixture to alcohol fermentation, and a distillation step for extracting the ethanol by distilling the raw material liquid.
