Fermentation inhibitor reducing device and the fermentation inhibitor reduction method of lignocellulosic biomass

摘要

An object of the present invention is to provide an effective fermentation inhibitor reducing device and the fermentation inhibitor reduction method of lignocellulosic biomass in a simpleThe present invention is directed to a fermentation inhibitor reducing apparatus lignocellulosic biomass, between saccharification tank with a fermenter, the fermentation inhibitors reduce and, saccharified solution generated by the saccharification tank and a fermentation inhibitor reducing device characterized by comprising a vacuum evaporator with a vacuum pump for cooling the glycated residue. The present invention provides a fermentation inhibitor reducing method for lignocellulosic biomass, the fermentation inhibitors reduce, and, in order to cool the sugar solution and saccharification residue generated in the saccharification step, it is generated in the saccharification step a fermentation inhibitor reducing method characterized by having a sugar solution and vacuum evaporation step of evaporating under vacuum saccharification residueBACKGROUND
