摘　　要：为探究亚硫酸法糖厂白砂糖糖粉中的不溶于水杂质含量,及其对产品质量的影响和控制策略,本研究通过采样检测、成分分析及工艺优化实验,系统研究了糖粉中不溶于水杂质含量及其来源和控制方法。检测结果显示,3家糖厂从白砂糖干燥间采样的18个糖粉样品中的不溶于水杂质平均含量为245 mg/kg;成分分析表明,糖粉沉淀杂质中主要阳离子成分为Ca^(2+)、Si^(4+)、K^(+)、Mg^(2+),主要阴离子组分为SO_(4)^(2-)、PO_(4)^(3-)、SO_(3)^(2-),主要来源于甘蔗原料和生产助剂及制糖生产过程中的化学反应所产生的物质。通过对中和pH值、硫熏强度、磷酸添加量、沉降时间等工艺参数的优化控制、强化糖浆上浮工艺、改进澄清中和设备等措施,能有效降低糖粉中的不溶于水杂质含量。研究表明,系统性的工艺优化和设备改进可有效控制糖粉及白砂糖中的不溶于水杂质含量,但需结合原料管理、结垢清洗、白砂糖筛分等措施,以实现白砂糖质量的持续改进。In order to investigate the content of water-insoluble impurities in white granulated sugar powder produced by sulfite sugar factory,as well as their impact on product quality and control strategies,this study systematically studies the content,sources,and control methods of water-insoluble impurities in sugar powder through sampling detection,component analysis,and process optimization experiments.The results show that the average content of water-insoluble impurities in 18 sugar powder samples collected from the white granulated sugar drying room by three sugar factories is 245 mg/kg.Composition analysis shows that the main cationic components in the impurities of sugar powder precipitation are Ca^(2+),Si^(4+),K^(+),Mg^(2+),the main anionic components are SO_(4)^(2-),PO_(4)^(3-),SO_(3)^(2-),the main sources are sugarcane raw materials and production aids,as well as substances produced by chemical reactions in sugar production.By optimizing and controlling process parameters such as neutralization pH value,sulfur fumigation intensity,phosphoric acid addition amount,settling time,strengthening syrup flotation process,and improving clarification and neutralization equipment,the water-insoluble impurities in sugar powder can be effectively reduced.Research has shown that systematic process optimization and equipment improvement can effectively control the water-insoluble impurities.However,measures such as raw material management,scaling cleaning,and white granulated sugar screening need to be combined to achieve continuous improvement in the quality of white granulated sugar.
