NOVELTY - The apparatus (11A) has a separation device (15) which separates an edible raw material (21), and a non-edible raw material (22). A sugar liquid adjustment unit (16A) produces a sugar liquid (23) derived from the edible raw material. A non-edible raw material saccharification unit (17A) saccharifies the product of hot water treatment of the biomass obtained by separation of the non-edible raw material, to produce a dilute sugar liquid (30). A dilute sugar liquid supply pipe (L21) supplies dilute sugar liquid to the sugar liquid adjustment unit.    USE - Sugar liquid manufacturing apparatus used for fermentation system (claimed) used in alcohol manufacturing system.    ADVANTAGE - The sugar liquid can be produced efficiently in a cost effective manner. The ethanol can be manufactured efficiently using the sugar liquid.    DETAILED DESCRIPTION - A hydrothermal decomposition apparatus (32A) performs hydrothermal decomposition of the non-edible raw material, and produces a biomass hydrothermally-treated material. A sulfuric acid decomposition apparatus adds a sulfuric acid to the non-edible raw material, and decomposes the non-edible raw material. The biomass hydrothermally-treated material comprises hydrothermal extraction fraction (40) containing the lignin component and hemicellulose component and the solid residue fraction (39) containing a cellulose component. The enzyme saccharification tank (33) obtains the sugar liquid (62) containing six-carbon sugar, by adding enzyme (61) to the cellulose in the solid residue fraction discharged from hydrothermal decomposition apparatuses. The enzyme saccharification tank (34) obtains the sugar liquid (64) containing five-carbon sugar, by adding enzyme (63) to the hemicellulose component in the hydrothermal extraction fraction discharged from hydrothermal decomposition apparatuses. INDEPENDENT CLAIMS are included for the following:    (1) a fermentation system which contains the sugar liquid manufacturing apparatus, and an alcohol fermenter (12) which ferments the sugar liquid;    (2) a sugar liquid manufacturing method; and    (3) a fermenting method.
