Abstract:
An apparatus for producing water-absorbing resin particles for which surface cross-linking treatment is conducted by spraying a surface cross-linking agent to a water-absorbing resin particle precursor and heating the agent and the precursor, the apparatus includes a treatment container in which the surface cross-linking treatment is conducted, a stirring device including a stirring member disposed in the treatment container, a heating device that heats an inside of the treatment container; and a spray nozzle disposed in the treatment container, the spray nozzle spraying into the treatment container the surface cross-linking agent supplied from a surface cross-linking agent supply source in an exterior of the treatment container through a supply pipe. In a flow path in the spray nozzle spanning from an entrance of the spray nozzle to a spray exit, a point whose opening cross-section is smallest in a flow path through which a fluid passes is the spray exit.

Claim (Index 3):
The apparatus for producing the water-absorbing resin particles according to  claim 2 , wherein the heating device is a heating jacket arranged on an outer circumference of the treatment container, and the strainer is disposed in the supply pipe on an outer side of the heating jacket.
