摘要
根据异相成核原理,在磷酸法沉降赤砂糖回溶糖浆过程中加入不同形貌的CaSO_3,以絮凝物沉降时间为指标,考察其对絮凝沉降过程的影响。并在单因素试验的基础上选取试验因素和水平,设计3因素3水平的响应面分析法,根据回归分析确定各因素的显著性和相互作用。结果表明对响应值影响显著的因素依次是:PAM用量>CaSO_3形貌>CaSO_3用量,最佳工艺条件为:花瓣状CaSO_3、CaSO_3用量0.4 mg/mL、PAM用量5 mg/kg。
According to the principle of heterogeneous nucleation, the method of phosphate sedimentation in the process of brown granulated sugar to dissolve the sugar syrup to join different morphology of CaSO3, with flocculating sedimentation time as an index, study its effect on the flocculation sedimentation process. And on the basis of single factor experiment to choose the test factors and levels, design three factors and three levels of response surface analysis, according to the regression analysis to determine the significance of various factors and interactions. Results show that the impact on the response value significant factors is in turn： PAM dosageCaSO3 morphologyCaSO3 dosage, the best process conditions for： petals CaSO3, CaSO3 dose of 0.4 mg/mL, PAM dosage of 5 mg/kg.
