Summary:PROBLEM TO BE SOLVED: To provide a method and apparatus for easily separating and recovering ethanol and water from fermentation moromi (unrefined sake), avoiding an adverse effect of crude protein and crude fat contained in several times more amounts compared with the case when a usual raw material of fermentation such as sweet potato and potato is used. SOLUTION: The method includes a first step of separating impurities from the fermentation moromi supplied in a decompressed pretreatment column, extracting an ethanol-containing component from the bottom of the depressed pretreatment column and introducing this into a depressed moromi column, recovering ethanol component from the top and of the depressed moromi column, recovering water content from the bottom of the depressed moromi column; a second step of feeding the ethanol component to an evaporator from the depressed moromi column, dehydrating the vapor generated in the evaporator in a dehydrator to recover purified ethanol and returning (supplying) a mixture of ethanol and water generated in the dehydrator to the first step; and a third step of separating solids from the water content recovered in the first step to recover water. The first step and the third step among these steps are operated at 90°C or lower, preferably at 80°C or lower. The apparatus for the method is also provided. COPYRIGHT: (C)2010,JPO&INPIT
