DIGESTIVE TANK

To provide a digestive tank capable of improving uniformity of mixing of a digested material in an entire internal space of the digestive tank.SOLUTION: There is provided a digestive tank 1A including an inner side surface 6s that focuses on a central side of an internal space 2 for housing a digested material W as it reaches an upper end 2u and a lower end 2b of the internal space 2 while defining the internal space 2, in which the digested material W housed in the internal space 2 is stirred by a stirring mechanism 10 around an axis parallel to a vertical direction, and a baffle plate 20A protruding upward from the lower end 2b of the internal space 2 forms an upward flow for the digested material W upward from the lower end 2b of the internal space 2, and uniformity of mixing of the digested material W can be improved in an entire internal space 2 of the digestive tank 1A because poor flow is unlikely to occur.SELECTED DRAWING: Figure 1 【課題】消化槽の内部空間の全体における被消化物の混合の均一性を向上させることができる消化槽を提供する。【解決手段】被消化物Ｗを収容する内部空間２を規定しつつ内部空間２の上端部２ｕ及び下端部２ｂに至るにつれて内部空間２の中心の側に集束する内側面６ｓを備えた消化槽１Ａにおいて、攪拌機構１０により内部空間２に収容された被消化物Ｗが上下方向に平行な軸周りに攪拌され、内部空間２の下端部２ｂから上方に突出した邪魔板２０Ａにより、被消化物Ｗに内部空間２の下端部２ｂから上方に向う上昇流が形成され、流動不良部が生じ難いため、消化槽１Ａの内部空間２の全体における被消化物Ｗの混合の均一性を向上させることができる。【選択図】図１
