| 摘要 |
The present invention provides a method for treating biomass involving a pre-treatment method for producing a biomass composition which exhibits high diastatic activity for glucose conversion from a cellulose-containing biomass starting material by continuously performing a hydrothermal treatment using a screw extruder, wherein: a crushing unit of the screw extruder crushes the cellulose-containing biomass starting material so as to make the maximum particle diameter thereof 1000μm or less, and adjusts the water content thereof to 20-80%; next, a heating unit thereof performs a hydrothermal treatment at a temperature of 150-250°C for 0.1-10 minutes while mixing and crushing, which has a mashing effect; and thereafter, a cooling unit downstream of the heating unit cools the treated product to 100°C or less, and a cellulose-containing biomass treated product which has an average particle diameter of 100μm or less is recovered. |
