SURFACE STRUCTURE CONTROL METHOD FOR WOODY RESOURCE, MANUFACTURING METHOD FOR BIO-ETHANOL, AND MANUFACTURING METHOD FOR ARTIFICIAL LUMBER

摘要

PROBLEM TO BE SOLVED: To provide a surface structure control method capable of controlling surface structures in woody resources in a state suitable for saccharification or the like.

SOLUTION: This surface structure control method controls the surface structures in the woody resources. A cellulose microfibril is broken fiber-likely by carrying out a refining operation of beating and tearing off the woody resource, and extremely micro-refining work is executed thereafter under the condition where a fiber characteristic is maintained in a refiner. The refining operation is carried out by rotating a rod provided eccentrically to the center axis of a cylindrical container in the container, and by feeding a woody resource chip, using wind power. The woody resource brought into "a feather-like beat fibrous state" is used, for example, as a raw material for bio-ethanol or a raw material (reinforcement material) of an artificial lumber.
