Abstract

Actual operations and processes inside a raw sugar factory and refinery were observed in the field practice in BUSCO Milling Company, Inc. Several unit operations are involved in raw and refined sugar manufacture. The first step in raw sugar production is the extraction of juice from the sugarcane in the milling tandems. Impurities in the mixed are removed by means of clarification. the impurities or the mud undergoes filtration for recovery of crystallization sugar while the clarified juice undergoes evaporation to remove the water and produce syrup. The syrup is further concentrated into a material called massecuite in pan boiling. 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 remelting the raw sugar or affination. The next process is carbonatation wherein the carbon dioxide is introduced to the liquor to further remove the impurities such as colorants and non-sugars. It proceeds to decolorization for higher degree of color removal using GAC and IER columns. 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 aimed to find the relationship of the purity of refinery process material to the quality of refined sugar was taken from the refinery laboratory and was compared using the Spearman rank correlation. Results showed no significant monotomic relationship between the apparent purity of refinery process materials and the quality of refined sugar.
