Abstract

Actual operations and practical applications were observed in the field practice in BUSCO Milling Company, Inc located in Butong, Quezon, Bukidnon Philippines Both unit operations and processes are involved in the sugar industry. The canes planted in nearby farms are harvested and delivered to the factory where it will undergo cane preparation. The prepared canes are then milled in the milling tandems to extract the juice. Clarification is done to remove the impurities from the extracted juice. The separated mud undergoes rotary vacuum filtration to recover the sucrose-containing juice while the clarified juice undergoes evaporation to remove excess amounts of water, producing syrup. The syrup is further concentrated into a material called massecuite in the batch and continuous vacuum pans. Raw sugar is separated from the molasses through centrifugation process. The raw sugar undergoes refining process to remove the colorants and increase purity. The process starts with removing the film of molasses through affination and the affined sugar id remelted. After melting, carbonation is done to further remove the impurities such as non-sugars. It proceeds to decolorization by for higher degree of color removal. It then undergoes evaporation, white pan boiling, centrifugation and packaging. Two grades of raw sugar is produced, the standard and premium grade. A special topic which focuses on the potential of replacing the current granular activated carbon with ion exchange resins for its decolorization process was also done. A new decolorization scheme was proposed wherein the polished liquor will only undergo ion-exchange in styrenic and acrylic resin vessels. Both schemes were compared based on their color removal and the economics of the new scheme as a replacement was studied.
