NOVELTY - The apparatus (1) has chamber (2) that accommodates kneading target object (100). A shaft (3) is rotationally driven in the chamber, by motor (5). A paddle (4) is connected to shaft. A paddle position control section (6) is used to change the position of paddle with respect to shaft so that the project area seen from rotation direction of shaft is changed. An air cylinder (6a) is used to generate the motive power for changing position of paddle. A link mechanism (6c) is used to transmit the motive power of actuator to paddle, so as to rotate.    USE - Multi-axial kneading apparatus of enzyme-reaction apparatus for cellulose and biomass saccharification apparatuses used in ethanol production apparatus (all claimed) for producing ethanol from wood-type biomass.    ADVANTAGE - The load of motor can be adjusted by adjusting the position of paddle by paddle position control section. The control of the load of motor can be enabled and the load of motor can be kept from exceeding the allowance.    DETAILED DESCRIPTION - The apparatus has a torque meter (6d) that is used to detect the load of motor. A control unit (6e) is used to set the position of paddle based on detection result of torque meter. INDEPENDENT CLAIMS are included for the following:    (1) an enzyme-reaction apparatus uses as kneading target object the mixture of polysaccharide thing and saccharogenic amylase containing cellulose;    (2) a cellulose saccharification apparatus has catalytic reaction unit that decomposes the degradation product generated by the enzyme-reaction apparatus into glucose using solid acid catalyst;    (3) a biomass saccharification apparatus has pressurized hot water reaction unit that selectively decomposes the hemicellulose which makes pressurized hot water act on biomass. A solid-liquid-separation unit separates the cellulose as solid from the process liquid of the pressurized hot water reaction apparatus. The cellulose saccharification apparatus decomposes the separated cellulose into glucose. Other catalytic reaction unit decomposes into monosaccharide derived from hemicellulose the hemicellulose degradation thing as separated liquid using solid acid catalyst; and    (4) an ethanol production apparatus has fermentation unit that generates ethanol from glucose generated by biomass saccharification apparatus and other fermentation unit that generates ethanol from monosaccharide derived from hemicellulose generated by biomass saccharification apparatus.
