IMPACT OF MASSECUITE FEED PROPERTIES ON CONTINUOUS HIGH GRADE CENTRIFUGAL PERFORMANCE

During recent seasons, the performance of continuous high grade centrifugals has been assessed for a wide range of processing conditions, which included varying the massecuite feed rates, wash water application rates and basket rotational speeds. The purging qualities of the feed massecuites were determined to have a major impact on the performance of the centrifugals in achieving the target polarisation of the sugar. Thepaper describes the techniques that have been used to define the effect of the massecuite feed properties and the extent to which fugalling performance is affected.
