A massecuite processing system of the type generally used in the separation of sugar crystals from molasses in the so called "High Grade Massecuites" produced in the process of making sugar from sugar cane and sugar beet. The massecuite is evenly spread over the perforated belt of a belt conveyor while a vacuum is maintained under the belt to aspirate the molasses through the belt into vacuum chambers located under the belt. The perforations of the belt are sized to prevent the aspiration of the sugar crystals with the molasses and in this way the sugar crystals are effectively separated from the molasses. The separated molasses is collected in the vacuum chambers from which it is transferred to a separately mounted molasses separating tank which is also under vacuum and from which the molasses is pumped to the molasses storage tanks generally used in sugar factories. The separated sugar crystals travelling with the moving belt are washed with hot water and steam afterwhich they are dried by means of a hot air stream and cooled by means of a stream of air at ambient temperature before being discharged for storage.
