Abstract

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.

Description

BACKGROUND

[0001] 1. Technical Field

[0002] The present invention relates to a pretreatment apparatus for cornstalk chips, and more particularly, to a pretreatment apparatus for removing pith from cornstalks and separating husks therefrom, a pulp manufacturing method using cornstalks, and a paper manufacturing method using cornstalk pulp.

[0003] 2. Description of the Related Art

[0004] Generally, paper is made from wood pulp as a main raw material. For countries suffering from lack of wood resources, pulp has been produced using herbaceous plants, such as straw, bagasse, reeds, and the like. Further, pulp production is carried out in small scale in home industries, thereby providing very low grade paper and many difficulties including insufficient dewatering in a paper manufacturing process. Such circumstances lead to prejudice in favor of wood pulp as raw materials for high grade paper. However, rapid industrial development and urbanization have occurred together with severe environmental ...
