Abstract: An apparatus and method for reducing sugar, crystal impact damage and lump formation in a centrifugal provides a resilient barrier ring which absorbs most of the impact energy of the crystals and which deflects the crystals so they are not struck by trailing high speed crystals. An air flow causes vibration of the barrier ring to prevent crystal sticking which could lead to lump formation. This air flow also reduces moisture content in the sugar housing to further reduce lump formation.

Abstract: An apparatus and method for providing reduced crystal damage in a sugar centrifugal includes provisions for avoiding scratching and other crystal damage by eliminating asperities and sharp edges at the transition between the screening zone and the discharge zone of a centrifugal basket. In addition, the distance on an upper shroud ring across which high velocity crystals slide is minimized to reduce the likelihood of scratching crystals on the surface of the shroud ring. Finally, the tangential velocity at which crystals are released from the centrifugal basket is minimized to reduce impact damage to the crystals.

Abstract: A sugar centrifugal operates at decreased speed to reduce crystal damage but suffers no loss of sugar crystal/molasses separation rate. This is accomplished by superposing a partial vacuum on the molasses chamber of the centrifugal which promotes removal of syrup and water from the sugar crystals through the centrifugal basket wall. Additional drying of the separated crystals is provided by injection of air above the sugar chamber to replace that which is extracted through the centrifugal basket wall.

Abstract: An apparatus and method for reducing sugar, crystal impact damage and lump formation in a sugar centrifugal includes a resilient deflector ring which absorbs most of the impact energy of the crystals while deflecting the crystals out of the path of trailing high speed crystals. An air flow parallel to the local surface of the deflector ring causes vibration of the deflector ring to reduce the tendency for crystals to stick while addition of a supply of water aspirated and atomized by the air flow maintains the ring surface free of syrup build-up which could cause crystals to adhere to the ring surface and form lumps.

Abstract: A continuously operable centrifuge for spinning off sugar massecuite has an upwardly conically expanded strainer basket (20) mounted for rotation about a vertical axis (16). A downwardly conically expanding massecuite distributor (40) rotating with the basket reaches into a floor region of the strainer basket substantially coaxially to the strainer basket. The lower rim of the distributor forms a throw-off edge. Inside and in the upper region of the massecuite distributor (40), a distributing cup (30) is for distributing massecuite. The peripheral wall of the massecuite distributor (40) is formed by several ring elements (41), (42, 43) which partly overlap in the axial direction leaving an annular gap (44, 45). The product distributor is surrounded by a downwardly conically expanding stationary bell (51) which forms a further gap or gap space between itself and the rotating rings.

Abstract: A process and device for the crystallization of sugar syrup is described. Sugar syrup is cooked to provide a massecuite. Thereafter, the massecuite is subjected to at least one stage of continuous mixing under vacuum to promote crystallization of the massecuite. The crystallized massecuite is then separated to separate the crystals from the mother liquor. The mother liquor is thereafter divided into a first discharge which is water syrup poor and a second discharge which is water syrup rich. Substantially all of the first discharge is recycled to the continuous mixing stage under vacuum. Accordingly, the massecuite and the crystals are subjected to a treatment having continuity during mixing under vacuum to maintain homogeneity of the sugar crystals.

Abstract: A water-conducting lance, fitted with a spray nozzle at an end thereof, is fixed to the top of a massecuite-separating centrifuge which has a rotating basket, to dispose the nozzle in adjacency to the top of the basket. The nozzle addresses the top of the basket, perpendicularly, and sprays pre-wetting water onto sugar crystals thereat, to insure a good mix of the crystals with subsequent mixing liquid (also water) in a mixing liquid zone, in order that a lump-free high brix magma will be produced.

Abstract: An annular compartment is disposed below the mixing ring of a rotating-basket, massecuite-separating centrifuge, to receive the magma therein. Eductors arrayed in the compartment receive hot water, and ingest magma, to eject the mix therethrough and to centrifuge the mix, while melting the sugar crystals in the magma. The melted crystals, now high brix sugar liquid, is overflowed into a companion compartment; from thence the liquid is passed over a weir, into a sub-compartment, for subsequent discharge.

Abstract: In a method and apparatus for eliminating liquid components and fine-grained components from a sugar suspension, control variables for controlling the centrifuge are obtained from a measurement of the quantity of material per unit of surface area in the filter cake formed in the centrifuge during the centrifuging process. In particular, a radiometric measurement can be used for this purpose. From the time course of the measurements obtained, relationships with the physical composition of the filter cake at the instant of measurement are derived and used to adjust process control variables, such as the quantity of water to be added and the length of the washing phase. The control of such a process can be made fully automatic, with optical quality, using a single continuous measurement.

Abstract: A seeding magma for seeding a solution of a crystallizable product is prepared from a suspension the crystals in a liquid phase. This suspension is delivered into a continuously rotating conical basket of a centrifugal drier. The basket has an upper output end and a screen is mounted therein. Rotation of the basket causes the suspension to be subjected to centrifugal forces causing crystals of a size interior to the mesh size of the screen to pass with the liquid phase through the screen and larger crystals to be retained on the screen and centrifugally displaced towards the upper output end and ejected therefrom. These crystals are forcefully projected against an impact surface disposed around the output end of the basket whereby the projected crystals are crushed on impact with the surface. The crushed crystals are recycled into the suspension delivered into the basket while the liquid phase with the crystals passed through the screen is removed for preparing the seeding magma.

Abstract: An air and massecuite warming device comprising a pair of nested, concentric frusto-conical tubular members positioned above a massecuite separating centrifuge in which steam is directed into the chamber formed between the nested members. The steam is discharged from the inner member by a plurality of nozzles located in the conical wall of the inner member forming a vortex. Before contacting the massecuite, the steam mixes with the air drawn through the centrifuge, raising the air temperature. This warm air reduces the massecuite viscosity by increasing the temperature of the massecuite and the temperature of the centrifuge elements contacting the massecuite thereby increasing the centrifuge separation capacity and improving the purity of the sugar produced.

Abstract: Beet juice is purified, then concentrated and treated in several steps for boiling and centrifugal separation to effect recovery of sucrose therefrom. The molasses remaining after the separation of sucrose from massecuite is treated with .alpha.-galactosidase to effect hydrolysis of raffinose present in the molasses. The resultant raffinose hydrolyzate is introduced into a calcium saccharate-forming step, wherein quicklime is continuously added to the hydrolyzate to form saccharate within the hydrolyzate. From the calcium saccharate-forming step, nearly the same volume of the saccharate-containing solution as that of the raffinose hydrolyzate fed therein is forwarded to a filtering and washing step. The resultant saccharate cake is sent back to the step for purification.
