Abstract
To provide a vertical centrifugal separation apparatus which recovers a centrifuged liquid with a reduced loss and is suitable for when a target is the centrifuged liquid, and a method of recovering the centrifuged liquid. In performing centrifugation, the liquid to be processed is supplied from a lower portion of a cylindrical rotational tube which rotates about a vertical axis, and the centrifuged liquid is discharged and recovered from an upper portion of the cylindrical rotational tube. When the centrifugation is stopped for cleaning the cylindrical rotational tube, for example, the cylindrical rotational tube is set to a first overturn position to recover the remaining centrifuged liquid, and then the cylindrical rotational tube is set to a second overturn position to pull the tube out of the casing. Such a structure allows the recovery of the centrifuged liquid as the target with a reduced loss and without waste.
