The present invention has developed, unlike a conventional technology, an apparatus and a technique for rind, inside and scrap separation, which has been the greatest impediment to the mass production of high-quality paper-making pulp, thereby enabling the production of high-quality pulp, enables produced, unbleached pulp to be used as a raw material for manufacturing industrial packaging paper because of the excellent strength of the pulp, allows bleached corn chemical pulp to be suitable for the manufacture of toilet and facial papers and tissues, and can be applied to various paper-making techniques by mixing pulps, having different characteristics, such as needle bleached chemical pulp, leaf bleached chemical pulp, and bleached chemical thermomechanical pulp (BCTMP). La présente invention, contrairement à la technologie conventionnelle, a développé un appareil et une technique pour la séparation de l'écorce, de l'intérieur et des débris, qui constituait jusqu'à présent le plus gros obstacle à la production en masse de pâte à papier de haute qualité, ce qui permet de produire de la pâte à papier de haute qualité, d'utiliser de la pâte à papier produite non blanchie en tant que matière première pour la fabrication de papier d'emballage industriel en raison de l'excellente résistance de la pâte, d'utiliser la pâte à papier chimique à base de maïs blanchie pour la fabrication de papier hygiénique et de mouchoirs en papier, et son application à différentes techniques de fabrication de papier en mélangeant les pâtes, ayant des caractéristiques différentes, telles qu'une pâte à papier chimique blanchie à l'aiguille, une pâte à papier chimique blanchie à la feuille, et une pâte à papier thermomécanique chimique blanchie (BCTMP). 본 발명은 종래 기술과 달리 고품질의 제지용 펄프를 대량 생산에 가장 큰 장애로 대두되었던 겉대, 속대 및 부스러기의 분리를 위한 장치와 기술을 개발함으로써 고품질 펄프의 생산을 가능하게 할 수 있고, 생산된 미표백펄프는 강도가 우수하여 산업포장용지 제조용 원료로 사용할 수 있으며, 표백 옥수수 화학펄프는 화장지(toilet and facial paper) 및 박엽지(tissues) 제조에 적합하고, 침엽수 표백 화학펄프, 활엽수 표백 화학펄프, 표백 화학 열기계펄프(BCTMP) 등의 특성이 다른 펄프의 혼합을 통하여 다양한 종이 제조 기술에 적용할 수 있다.
