<p>PURPOSE:A conventional still is provided with, on its top, a rectification column having a plurality of rectification trays and the alcohol steams from individual trays are appropriately introduced into the cooler whereby fusel oil and higher fatty acids are largely removed in the distillation process. CONSTITUTION:The fermentation mash 2 is placed in the boiler 1 of the still and alcohol is distilled. The alcohol vapor is introduced into the water at low temperatures in the fractionation chambers 31f, 32f, 33f in the rectification column 3 to remove the high-boiling fractions of fusel oil and higher fatty acid, then the vapor is cooled with cooler 4 into liquid. Thus, fusel oil and higher fatty acids are largely removed during the distillation process.</p> |
