Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fluidized bed device capable of reducing processing time while maintaining product qualities.SOLUTION: A fluidized bed device 1 comprises: a gas supply unit 8; a material container 7; a spray casing 6 in which a flow chamber 17 is formed; and a filter casing 5. The material container 7 comprises a perforated plate 22, a cylindrical straight section 23 and a reverse truncated cone-shaped tapered section 24. The spray casing 6 is formed in a tapered shape, the cross-sectional area of the upper end of which is larger than the lower end. For the fluidized bed device 1, when the amount of liquid added per unit perforated plate area converted to a heat quantity is B kJ/min cmand the PL value, which represents the liquid-absorbing ability of the particles, is PL, B is set to be PL×1.3≤B≤PL×3.2. 【課題】製品品質を維持しつつ処理時間の短縮が可能な流動層装置を提供する。【解決手段】流動層装置１は、給気ユニット８と、原料容器コンテナ７、流動室１７が形成されたスプレーケーシング６、フィルタケーシング５を有する。原料容器コンテナ７は、目皿板２２と、円柱状のストレート部２３と、逆円錐台形状のテーパ部２４を有する。スプレーケーシング６は、その上方側が下方側よりも断面積が大きいテーパ形状に形成される。流動層装置１にあっては、単位目皿面積当たりの液体の加液量を熱量に換算した値をＢ(kJ/min・cm2)、粉粒体の吸液性を示すＰＬ値をＰＬとしたとき、Ｂは、ＰＬ?１.３≦Ｂ≦ＰＬ?３.２に設定される。【選択図】図１
