Title:
METHOD FOR COLLECTING SUGAR FROM SACCHARIFICATION SLURRY AND WASHING DEVICE FOR WASHING RESIDUE
Document Type and Number:
WIPO Patent Application WO/2014/103184
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide a sugar collection method for collecting sugar quickly and easily from a saccharification slurry obtained after hot water treatment of a cellulose biomass slurry. Another purpose of the present invention is to provide a saccharification slurry residue-washing device suitable for implementing such a sugar collection method. The sugar collection method and the washing device according to the present invention: supply a cellulose biomass saccharification slurry onto a conveyor provided with a net conveyor belt; dehydrate the saccharification slurry and sprinkle washing water on the dehydrated residue on the conveyor; and dissolve the sugars remaining in the residue into the washing solution. The washing of the residue is performed by sprinkling the washing water continuously on the residue from multiple washing water-sprinkling devices disposed in a series so that the residue movement direction is the opposite of the washing water movement direction. Washing water that has washed residue is used as the washing water for the adjacent washing water sprinkling device that is on the side opposite to the conveyor movement direction.
