ABSTRACT:
Sugar is continuously crystallized from a sugar bearing solution in a single stage vacuum pan by a method and apparatus comprising means for and the steps of continuously supplying a sugar bearing solution of a constant, desired purity to the vacuum pan by combining a relatively low purity sugar bearing solution flow stream with a relatively high purity sugar bearing solution flow stream while regulating the ratio of relatively low to relatively high purity sugar bearing solution in the combined flow stream, continuously supplying sugar seed crystals having a relatively uniform crystal size distribution to the vacuum pan, continuously boiling at least a portion of the sugar bearing solution and sugar seed crystals in the vaccum pan to form a boiling massecuite, and continuously removing at least a portion of the massecuite from the vacuum pan. Sugar crystals of at least a predetermined desired size are then continuously separated from the massecuite in a continuous centrifugal separator and conventionally further processed while the supernatant sugar bearing solution and sugar crystals smaller than the desired size are stored in a run-off storage tank for later conventional further processing.
