To provide an apparatus for producing a polysaccharide solid, which is capable of suppressing carbon disulfide emission and has less environmental load without degrading productivity; a method for producing a polysaccharide fiber; a polysaccharide fiber; a cord; a fiber-rubber composite, and a tire.
The apparatus 20 for producing a polysaccharide solid comprises: a dissolving device 12 for preparing a polysaccharide solution obtained by dissolving a polysaccharide raw material 14 in a liquid containing an ion solution; a discharger 1 for discharging the polysaccharide solution; a solidifying tank 5 for holding a solidifying liquid for contacting the discharged polysaccharide solution to solidify the polysaccharide; and a washing tank 8 for holding a washing liquid for washing the solidified polysaccharide. The contact sites with the ion solution of the dissolving device 12, the discharger 1, the solidifying tank 5, and the washing tank 8 are made of a material having corrosion resistance to the ion solution.
