PRETREATMENT APPARATUS FOR REMOVING PITH FROM CORNSTALK, PULP MANUFACTURING METHOD USING CORNSTALK, AND PAPER MANUFACTURING METHOD USING CORNSTALK PULP
PRETREATMENT APPARATUS FOR REMOVING PITH FROM CORNSTALK, PULP MANUFACTURING METHOD USING CORNSTALK, AND PAPER MANUFACTURING METHOD USING CORNSTALK PULP
A pretreatment apparatus for removing pith from cornstalks and separating husks therefrom includes a casing that receives cornstalks in a free-fall manner through an upper side thereof and allows the corn stalks to be discharged through a lower side thereof, and a rotor inserted into the casing and rotating inside the casing to hit cornstalk chips. The rotor includes a shaft inserted into the casing to be rotated by external force, a cover member holding the shaft so as to allow rotation of the shaft therein and connected to the entirety or part of an open upper side of the casing, and a hitting unit formed on a circumference of the shaft and hitting the corn stalks input into the casing.
