Beschreibung
Zusammenfassung:	The present invention provides a device for manufacturing cellulose nanofibers. The device comprises: a pressing unit to which a cellulose raw material, ultrapure water, and a sublimable material are added, and which presses the cellulose raw material to accelerate swelling of the cellulose; a pulverizing unit which includes a stator and a rotor and pulverizes and disperses the cellulose raw material discharged from the pressing unit to manufacture the cellulose raw material into nanofibers; and a homogenization unit for pulverizing and dispersing the cellulose raw material, manufactured into the nanofibers by the pulverizing unit, by collision force, shear force, and cavitation due to a high pressure. The pressing unit includes a vortex forming unit for imparting shear force to the cellulose raw material. The vortex forming unit forms a vortex in the pressing unit to apply centrifugal force, impact force, and shear force to the swollen cellulose. 본 발명은 셀룰로오스 원료, 초순수 및 승화성 물질이 첨가되고, 상기 셀룰로오스 원료를 가압하여 셀룰로오스의 팽윤을 가속화하는 가압부; 고정자 및 회전자를 포함하고, 상기 가압부에서 배출되는 셀룰로오스 원료를 분쇄 및 분산하여 소섬유화하는 분쇄부; 및 상기 분쇄부에서 소섬유화된 셀룰로오스 원료를 고압에 의한 충돌력과 전단력 및 공동현상으로 분쇄 및 분산하는 균질화부를 포함하고, 상기 가압부는 셀룰로오스 원료에 전단력을 부여하는 와류 형성부를 포함하고, 상기 와류 형성부는 상기 가압부 내에서 와류를 형성하여 팽윤된 셀룰로오스에 원심력, 충격력 및 전단력을 부여하는 셀룰로오스 미세섬유의 제조 장치를 개시한다.
