等の破壊が生ずることなく気液撹拌される。With the auxiliary vanes, a high-velocity flow is generated in the space between the peripheral edge of the flat plate and the auxiliary vanes, and the flow of the peripheral edges of the flat plate is rectified by the curvature of the auxiliary vanes, thereby suppressing the generation of vortex flow. As a result, the shearing force is weakened and the separation vortex is reduced, and gas and liquid are agitated without destruction of microorganisms.
