Zusammenfassung:PROBLEM TO BE SOLVED: To provide a stirring apparatus for stirring and mixing a mixture, in particular a liquid containing insoluble particles, that enables good mixing at a relatively low rotational speed.SOLUTION: A stirring apparatus comprises: a container containing a mixture; a rotor comprising a shaft and a rotor blade; a driving means rotating the shaft; and at least one flow disturbing object between the shaft and a circumferential inner wall of the container. The flow disturbing object is fixedly mounted such that the flow disturbing object is stationary in the container, or is mounted rotatably around the shaft and is connected to the driving means such that the flow disturbing object is rotated at a rotational speed, that is different from the rotational speed of the shaft, and/or in a rotational direction that is different from the rotational direction of the shaft. The at least one flow disturbing object is located between the shaft and a trajectory followed by the rotor blade of the rotor when in operation, and the rotor blade has a shape that directs the mixture inwardly to the at least one flow disturbing object.SELECTED DRAWING: None 【課題】比較的低い回転送度で、良好な混合を可能とする、混合物、特に不溶性粒子を含む液体を撹拌・混合する撹拌装置の提供【解決手段】混合物を含む容器と、シャフト及びロータブレードを備えるロータと、シャフトを回転させる駆動手段と、シャフトと容器の円周内壁との間の少なくとも1つの流れ阻害体と、を備えており、流れ阻害体は、流れ阻害体が容器内に静止するよう固定して取り付けられる、又は、流れ阻害体がシャフトの回転速度と異なる回転速度、及び/又は、シャフトの回転方向と異なる回転方向で回転するよう、シャフトの回りに回転可能に取り付けられ、駆動手段に接続されており、運転中、少なくとも1つの流れ阻外体はシャフトとロータブレードによって辿られる軌道との間に位置し、ローターブレードは、少なくとも一つの流れ阻外体に対して混合物を内側に向かせる形状を有している撹拌装置。【選択図】なし
