Abstract
This invention is a dual axis, continuous flow centrifuge apparatus and method. A centrifuge head rotates in a vertical orientation about a first axis which, in turn, is rotated in a horizontal plane about a second axis. The rotation of the centrifuge head is matched to the rotation of the second axis to cancel out any net rotation of flexible conduits attached to the centrifuge head. The nonrotating coupling of the conduits permits continuous flow through the centrifuge head in the absence of seals. An angled centrifuge chamber inside the centrifuge head provides a more rapid separation of the components in the liquid passing through the centrifuge head. The path of travel of a particle in a centrifuge chamber inside the centrifuge head follows a generally cycloidal path thereby undergoing a pulsatile centrifugal force component.
