NOVELTY - The apparatus (10A) has horizontal type reaction tank (11) that reacts cellulose containing biomass (26) with saccharogenic amylase, for obtaining saccharification slurry, while stirring cellulose and saccharogenic amylase (32). A vertical-type reaction tank (13) saccharifies saccharification slurry (33) for obtaining saccharified liquid (41). A saccharification slurry supply line (L11) is provided for connecting two reaction tanks. A jacket (12) is provided in circumference or wall surface of horizontal type reaction tank, for heating the horizontal type reaction tank.    USE - Apparatus for manufacturing sugar liquid from cellulose containing biomass for use during fermentation production process of chemical substance.    ADVANTAGE - The slurry liquid is provided in vertical-type reaction tank in vertical direction, so that the reaction efficiency of cellulose containing biomass and saccharogenic amylase is improved. Since cellulose containing biomass and saccharogenic amylase are reacted efficiently, the saccharification time is shortened by performing saccharification reaction in two steps of horizontal type reaction tank and vertical-type reaction tank. Thus the high concentration sugar liquid is efficiently manufactured at low cost.    DETAILED DESCRIPTION - A stirring shaft (21) is provided inside at a horizontal direction, and in which a stirring blade (22) is provided. A saccharification slurry discharge port (34) is provided for discharging the saccharification slurry on the opposite side to biomass inlet (25) of horizontal type reaction tank. An antitussive unit (38) is provided to dam up the flow of the saccharification slurry to the saccharification slurry discharge port. A biomass supply apparatus is provided for supplying cellulose containing biomass to the upstream flow side of the biomass inlet of horizontal type reaction tank. The saccharogenic amylase is supplied to the horizontal type reaction tank from second enzyme supply path (31). The temperature of thermal medium is 40-60 degrees C. The thermochemical process is selected from the group consisting of ammoniation, hydrothermal treatment, blasting process, alkali treatment, and dilute sulfuric acid process. An INDEPENDENT CLAIM is included for a method for manufacturing sugar liquid from cellulose containing biomass.
