FIBER-PROCESSING APPARATUS AND FIBER-PROCESSING METHOD

摘要

A fiber-processing apparatus includes a feed section feeding a dispersion containing liquid and a fibrous material which contains a polysaccharide as a main component and which is dispersed in the liquid and also includes an ejection section ejecting a fluid in which the concentration of the fibrous material is lower than that in the dispersion toward the fed dispersion to crush the fibrous material in the dispersion. The feed section preferably feeds the dispersion vertically downward. Furthermore, the ejection section preferably ejects the fluid downward rather than horizontally.
