APPARATUS FOR PRODUCING SACCHARIDE SOLUTION THAT USES BIOMASS AS FEEDSTOCK

摘要

This apparatus for producing a sugar solution that uses biomass as feedstock comprises: a device for carrying out high-temperature processing of a biomass feedstock; a cooling means (90) for cooling a biomass liquid that has undergone high-temperature processing; an enzyme saccharification tank (103) in which a cooled liquid (101B) is enzymatically saccharified; a foreign substance removal unit (113) provided with a solid-liquid separation device (112) and a microfiltration (MF) membrane (113a) for removing water-insoluble substances contained in a sugar solution (104) extracted from the enzyme saccharification tank (103); a dilution tank (132) disposed downstream from the foreign substance removal unit (113), in which the sugar solution from which water-insoluble substances have been removed is diluted by adding water; a water separation unit (116) provided with a reverse osmosis (RO) membrane (116a) for removing water (114) from the diluted sugar solution to obtain a concentrated sugar solution (115).
