PURPOSE:To reduce the total amount of steam to be used and to take out fusel oil, etc. readily, by introducing a distillated liquid with its solid materials in unrifined sake removed by a column of unrefined sake into a rectifying column, concentrating a bottom product by an evaporator, and recycling the concentrate into the top of the rectifying column. CONSTITUTION:The unrefined sake 8 with soluble salts and solid materials is fed to the given position of the column 2 of unrefined sake, the live steam 10 and the vapor through the vapor tube 1 from the evaporator 6 are blown to the bottom of the column 2. By the distillation in the column 2 of unrefined sake, salts of solid flotation materials and soluble solid materials contained in the unrefined sake gather in the bottom product, and the salts are discharged out of the system together with the bottom product 24. The salts are concentrated by steam 44 in the evaporator 6 into which the bottom product of the rectifying column 4 is introduced, and the concentrated solution is sent to the salt blending tank 38. The vapor produced in the evaporator 6 is used as a heat source for the column 2 of unrefined sake.
