Clarifying the remelt syrup of brown granulated sugar by phosphate flocculating process
摘要
Abstract
The remelt syrup of brown granulated sugar was studied using the Calcium phosphate flocculation method. The sedimentation velocity and compactness of the floc sedimentation were observed under different adding order of the phosphoric acid and calcium hydroxide,and the way of adding them simultaneously was used for the flocculating sedimentation. The effect of the phosphoric acid dosage, preliming pH,reaction time,and reaction temperature on the decolorization and deturbidity of the remelt syrup of brown granulated sugar were investigated. The orthogonal tests were proceeded to optimize the experimental conditions,and the results showed that the optimal phosphoric acid dosage was 210 mg/kgBx,reaction time was 5min,the reaction temperature was 85℃,and the preliming pH was 7.10. Under the optimal conditions,the decolorization rate reached 70.1% and the deturbidity rate reached 97.7%. The results proved the feasibility of the calcium phosphate flocculation method for the clarification and decolorization of the remelt syrup of brown granulated sugar.关键词
