| abstract |
A sugar solution production apparatus (10A-1) comprises a saccharification tank (11) for obtaining a saccharified solution (16) including solid content from cellulose-containing biomass, a solid-liquid separation device (12) for separating out the solid content from the saccharified solution (16) to obtain a sugar solution (22), an enzyme recovery solution tank (13) for storing an enzyme recovery solution (24), a sugar solution extraction line (L11) for extracting the sugar solution (22) from the solid-liquid separation device (12), a hot water supplying means (13) for supplying hot water (25) to the solid-liquid separation device (12) to obtain the sugar solution (22) from the solid content with a saccharifying enzyme (15) adsorbed onto the solid content, an enzyme recovery solution supply line (L12) for supplying the enzyme recovery solution (24) to the solid-liquid separation device (12) from the enzyme recovery solution tank (13), an enzyme recovery solution recovery line (L13) for feeding to the enzyme recovery solution tank (13) the enzyme recovery solution (24) obtained by recovering the saccharifying enzyme (15) within the solid content, and an enzyme recovery solution return line (L14) for returning the enzyme recovery solution (24) to the saccharification tank (11). |
