Technologists throughout the world have, for several decades now, sought to design a continuous centrifugal capable of producing high quality sugar. In 1993, STG Engineering constructed a prototype continuous centrifugal for Australian A and B massecuites (CSR Ltd.) which produce high grade sugar as feed stock for international refineries. This centrifugal was found to produce high quality sugar with none of the quality disadvantages that had been previously experienced as crystal breakage and lump formation. Soon after, a white sugar prototype was built for Manildra Harwood Sugars Refinery for use on first, second and third white massecuites and producing high quality white refined sugars. The sugar is free from broken crystal and contains no lumps. The crystal yield is generally higher than for batch machines. The power consumed is approximately 0.5 kW/(t · h) massecuite and the standard unit has a total installed power of 45kW. This paper outlines various design features of the centrifugal, the performance of the centrifugal and the implications to sugar producers. The results and conclusions reached to date have been established over three years on affination, two milling campaigns on raw sugar and one year on refined sugar.
