摘要： The control unit operates the stirring device sequentially in a defiberization operating mode, a transition operating mode, and a dilution operating mode. In the defiberization operating mode, the stirring blade is rotated at the revolution speed for defiberization of waste paper in the disaggregating water stored in the stirring chamber to generate a waste paper pulp slurry. In the transition operating mode, the dilution water from the water supply unit is supplied to the waste paper pulp slurry while rotating the stirring blade at the revolution speed for defiberization to stir the waste paper pulp slurry. In the dilution operating mode, the dilution water from the water supply unit is supplied to the waste paper pulp slurry while rotating the stirring blade at the revolution speed for stirring, lower than the revolution speed for defiberization, to stir the waste paper pulp slurry.
