Apparatus for producing ethanol from biomass resources and method for producing ethanol from biomass resources

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of carrying out a distillation process without elevating the concentration of ethanol in a culture medium during saccharification fermentation and transferring impurities such as raw materials and cells to a distillation apparatus. The ethanol production apparatus of the present invention comprises a fermentation culture tank for saccharifying and fermenting biomass resources, a supply port capable of supplying gas to the fermentation culture tank, a recovery pipe for liquefying the gas discharged from the fermentation culture tank, And a recovery tank for recovering the ethanol discharged from the recovery pipe. A fermentation and culture process for saccharifying and fermenting biomass resources using the ethanol production apparatus of the present invention, a distillation process for distilling a gas discharged from the fermentation culture tank, and a recovery process for recovering the gas discharged from the exhaust process. carry out.
