Abstract

　少なくとも２室からなる乾燥室を有する連続式流動層で乾燥を行う。第１乾燥室での乾燥と第２乾燥室以降のいずれかの乾燥室での乾燥との間に、粉砕を行って乾燥する。流動層内に伝熱管を有する連続式流動層で乾燥を行う。また、乾燥温度は、第１乾燥室よりも第２乾燥室以降のいずれかの乾燥室の方が高く、第１乾燥室での乾燥温度が、８０°C以上、２００°C以下の範囲内で、第２乾燥室以降のいずれかの乾燥室での乾燥温度が、１００°C以上、２２０°C以下の範囲内で乾燥する。また、単量体水溶液を重合する工程（１）、得られた含水ゲル重合体を乾燥する工程（２）、乾燥物を粉砕して、または、粉砕及び分級して粒度を制御する工程（３）、および粒度制御された吸水性樹脂粉末に表面架橋を行う工程（５）を順次含み、表面架橋を行う工程（５）の前に、粒度制御された吸水性樹脂粉末にさらに第２の加熱乾燥を行う工程（４）を含む。また、表面架橋を行う工程（５）に供する吸水性樹脂の含水率（１８０°Cで３時間の乾燥減量で規定）を０～３重量％とする。これにより、物性に優れた粒子状吸水性樹脂を、低コストで高い生産性を確保しながら効率的に得ることができる吸水性樹脂の製造方法を提供する。
