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 4):
The apparatus for producing the water-absorbing resin particles according to  claim 2 , wherein\n the supply pipe for the surface cross-linking agent includes a first pipe that is a header pipe having plural spray nozzles connected thereto and a second pipe that connects the surface cross-linking agent supply source and the first pipe to each other, and the first pipe and the plural spray nozzles are arranged inside the treatment container, and the strainer is disposed in a portion on an outer side of the treatment container, of the second pipe.
