PROBLEM TO BE SOLVED: To provide a reaction apparatus in which scattering of solid contents in fermented raw sake during vaporization operation can be suppressed, and thereby causing no problem of sticking of the solid contents to a heating surface of a vapor phase portion of the inner wall of a reaction vessel or of a distillation still.SOLUTION: The reaction apparatus of the present invention comprises: a reaction vessel that produces ethanol by the glycation and fermentation reaction of a biomass in raw material slurry obtained by mixing a biomass raw material with water, and distills the produced ethanol primarily; agitating means that agitates a raw material slurry in the reaction vessel and the obtained fermented raw sake; heating means that is provided around the reaction vessel and heats a raw material slurry or a fermented raw sake for glycation and fermentation reaction or ethanol distillation; a measurement part that measures the liquid level in the reaction vessel; and a control part that on the basis of the liquid level measured by the measurement part, controls the maximum height heated by the heating means so as to be equal to or below the liquid level.SELECTED DRAWING: Figure 1 |
