Abstract: A continuously operable sugar centrifuge separates sugar massecuites into syrup portions of differing quality and crystalline sugar. The centrifugal screening basket is mounted for rotation within a housing divided into a plurality of different compartments for receiving syrup portions of differing quality from the screening basket. The housing also includes a first common collecting chamber for green syrup and a second common collecting chamber for high green syrup. Adjustable valves are provided between at least some of the compartments and the collecting chambers for alternatively connecting a compartment to either the first or second collecting chamber for separate discharge of syrup according to the quality of syrup received in the compartment. Mixing of syrup portions of differing quality is prevented by sealing elements even though the transition zone from green syrup to high green syrup shifts up or down along the basket wall.

Abstract: A continuously operating centrifugal or centrifuge for centrifuging sugar massecuites and for remashing the centrifuged sugar, comprises a ring conduit with nozzles for mixing liquid directed at the upper wide end of the centrifugal basket. The ring conduit is arranged in a housing having a cover, above a frustum-shaped centrifugal basket equipped with screens and rotating about a vertical axis of rotation. A conical baffle member is arranged radially outside of the upper edge of the centrifugal basket for intercepting the sugar crystals. A cover ring is mounted at the upper end of the centrifugal basket at a small distance from the ring conduit. The radial width of the cover ring corresponds at least to the spraying range of the nozzles for the mixing liquid. The conical baffle member is shaped like a frustum and opens upwardly. The centrifuge includes a mixing compartment enclosed by smooth walls.

Abstract: A high concentration sugar solution is produced by contacting sugar crystals as they emerge from a centrifuging basket, with pressurized solvent liquid sprayed from a plurality of nozzles to form a turbulent mist of solvent and to envelope the sugar crystals which are forced to travel through said turbulent mist of solvent to impinge upon a baffle guide ring. The turbulent flow of solvent mist and solvent enveloped sugar crystals is guided along said baffle guide ring to a back-up location, where sugar solution, air, and liquid mist are forced through a gap and over a damming ring wall surrounding the gap. The centrifuge for performing the foregoing process includes a centrifuging basket with an upper rim over which the sugar crystals emerge. A solvent supply ring with nozzles facing toward the rim is arranged above the upper basket rim. The baffle guide ring curves downwardly and surrounds an inner housing which in turn surrounds the basket.
