Title: DEVICE FOR PRODUCING ETHANOL FROM BIOMASS RESOURCE AND METHOD FOR MANUFACTURING ETHANOL FROM BIOMASS RESOURCE
Abstract:
[Problem] To provide a technique that enables implementation of a distillation step in which, during saccharification and fermentation, an increase in ethanol concentration in a culture medium is suppressed without transferring impurities such as a raw material or bacterial cells to a distillation device. [Solution] The device for producing ethanol according to the present invention has: a fermentation culture tank for saccharification and fermentation of a biomass resource; a supply outlet that can send a gas to the fermentation culture tank; a recovery tube for liquefying a gas discharged from the fermentation culture tank; and a recovery tank for recovering ethanol discharged from the recovery tube. This device for producing ethanol is used to implement: a fermentation culture step for saccharification and fermentation of a biomass resource; a distillation step for distilling a gas discharged from the fermentation culture tank; and a recovery step for recovering a gas discharged during a gas discharge step.
