Abstract
A condenser for removing vapor from freeze dryers and other vessels includes a three-stage cyclonic or turbine-like vapor distributor mounted for rotation about the axis of an elongated horizontal delivery tube extending through the axial center of the condenser chamber. The delivery tube mounts end and radial spray nozzles for selectively spraying cleansing fluid and sterilizing steam onto the interior surfaces of all components within the condenser chamber, including a plurality of condenser members arranged in radially offset configuration about the delivery tube in an optically dense configuration which requires vapors to impact the cold surfaces of the condenser members before contacting the inner surface of the enclosing condenser chamber. Optical density is achieved by providing the condenser member as sheets of metal formed with a serpentine passageway between them for the circulation of a coolant. Alternatively, optical density may be achieved by providing the condenser member as metal tubing bent in serpentine shape with open spaces between the bent sections, and enclosing the array of tubular condenser members in a cylindrical wall spaced inwardly from the condenser cham…
