摘要： A high-speed agitation type mixer of a continuous extruding method including a plurality of agitating members provided around a rotational shaft inside a fixed casing is used to mix and react a water absorbing resin containing a carboxyl group with an aqueous liquid containing, for example, a crosslinking agent that can react with the carboxyl group. The agitating members of the mixer of a continuous extruding method are provided so as to form in the ejection side a second area whose thrusting force is weaker than the thrusting force in a first area in which the water absorbing resin supplied into the casing is dispersed. A device for manufacturing a water absorbing agent is thus offered which boasts good absorbency under pressure and always maintain its excellent performance with end products.
