Titan CC Series Continuous Batch Centrifugals

The curb (monitor case) forms the housing and support structure for the rotating elements and contains internal compartments for separated sugar and molasses. An overrunning slinger/seal is incorporated at the larger diameter of the basket to prevent leakage between sugar and molasses compartments. The "thin" metal parts of the molasses compartment are made of stainless steel. An all stainless steel curb assembly is available.

In Titan CC Series, the center of gravity of the spindle and basket assembly is located between the spindle bearings. The rotating components are mounted within the curb using elastomeric mounting pads. Locating the mounting close to the center of rotation reduces the load on the elastomeric elements. The low center of gravity of the rotating mass and the unique design of the flexible-support assemblies provide smooth, stable operation.

Power is transmitted through a set of belts and pulleys from the squirrel cage induction drive motor to the basket spindle assembly. Drive belt tension is maintained by an adjustable motor base. The driven pulley is separately supported on its own bearings and connected to the basket spindle with a flexible coupling. This feature isolates the spindle bearings from the undesirable radial load imposed by the belt drive of larger, higher capacity motors. The drive spindle is assembled with heavy-duty, anti-friction type bearings that are designed to meet all normal load and duty conditions. The bearings are lubricated with filtered oil circulated by a pump common to the centrifugal battery. A flow switch is provided at the centrifugal to assure oil flow to the bearings. The squirrel cage induction motor is simple and reliable. The drive motor is provided for wye start-delta run. Electronic soft-start starting is available.

The Western States' basket is a one piece, centrifugally cast, heat treated, special alloy, stainless steel. Providing maximum resistance to stress corrosion cracking. Centrifugal casting allows a tapered cross section of the basket wall to provide maximum strength while reducing the rotating mass of the basket. Dynamic balancing ensures smooth operation. A series of wide annular grooves are precision machined in the bowl, then holes are accurately drilled within the grooves to provide unrestricted drainage. An 8 mesh stainless steel woven wire backing screen is fitted in a recessed surface of the basket and permanently welded in place. The backing screen is calendered to provide maximum support for the working screen while minimizing deformation. Soft nickel chrome-plated or stainless steel filtering screens are available in a wide variety of open areas and slot sizes for all types of massecuites. Western States' screen clamp system is quick and reliable. The top-bolted screen clamp holds the filtering screen firmly in place between the mating surfaces of the clamp and basket. No special fixtures or rings are required. Screens can be replaced without disassembly. The fastening bolts are isolated from the massecuite stream.

Proper pretreatment of the massecuite before it is distributed onto the screen is crucial for good separation and optimum capacity. The totally enclosed feed system has a hollow stainless steel feed guide rod passing through the orifice and extending the length of the enclosed feed tube. The feed guide rod has 4 drilled holes located just below the orifice which allows for the injection of process water directly into the feed stream. Coaxial introduction of water allows the massecuite and the precisely metered water to mix thoroughly and evenly with no splashing. A halo steam collar is fitted to the enclosed feed tube to allow the addition of steam into the feed tube. Surrounding the feed stream with steam raises the temperature of the massecuite before it enters the loading bowl. The basket is fitted with a perforated, adjustable pipe to introduce live steam directly onto the face of the basket. By using live steam directly on the sugar, the viscosity of the molasses is reduced resulting in increased capacity. For processing high-grade sugar, water can be injected into the steam pipe to provide washing of the crystal for improved sugar quality. All process water and steam pass through a flowmeter and pressure gauges for complete operator control and repeatability.
