FERMENTATION APPARATUS THAT USES BIOMASS AS FEEDSTOCK

摘要

There is provided an apparatus for treating a biomass feedstock at a high temperature, including: a cooling means for cooling a biomass liquid treated at a high temperature; an enzymatic saccharification tank for subjecting a cooled treated liquid to saccharification with an enzyme; a solid-liquid separation apparatus for removing water-slightly soluble fermentation inhibitory substances contained in the saccharide solution taken out from the enzymatic saccharification tank and a foreign substance removing unit provided with a microfiltlation (MF) membrane 113a; a dilution tank, disposed downstream of the foreign substance removing unit, for adding water thereto so as to dilute the saccharide solution; a water separation unit, provided with a reverse osmosis (RO) membrane, for removing water from the diluted saccharide solution to obtain concentrated saccharide solution; and a fermentation tank for fermenting the concentrated saccharide solution.
