摘要
目的:研究以果葡糖浆为原料,利用模拟移动床法(simulated moving bed,SMB),从果葡糖浆中分离第3代高纯度果糖的工艺方法。方法:首先通过对分离度影响因素的分析,进行单柱脉冲实验,确定树脂型号、进料体积、进料流速、进料浓度以及操作温度等操作参数,然后通过安全因子法得到SMB的简易参数设计方法,确定模拟移动床的理论参数,并在实验中修正得到实际的最佳参数。结果:理论模拟结果很好的吻合实验结果,实验得到模拟移动床最佳参数为切换时间469s、进料流速0.325L/h、洗脱液流速1.574L/h、提取液流速0.902L/h、提余液流速0.951L/h、循环流速1.897L/h;通过模拟移动床法分离第3代高纯果糖纯度为99.91%、得率为80.32%、葡萄糖纯度为92.34%、得率为90.13%。
Purpose： To prepare high fructose corn syrup Fg0 （with a fructose content of 90%） from F42 （with a fructose content of 42%） by simulated moving bed chromatography （SMB）. Methods ： The effects of resin type, feeding volume and rate, corn syrup concentration and operating temperature on separation degree were investigated by single-column pulse experiments. The theoretical SMB parameters were identified by the safety factor method and experimentally modified to be the optimal parameters. Results： The theoretically stimulated and experimental results showed good agreement. The optimal SMB parameters were switching time 469 s, feeding rate 1.574 L/h, elution solution flow rate 0.325 L/h, extraction solution flow rate 0.902 L/h, raffinate flow rate 0.951 L/h, and cycling flow rate 1.897 L/h. The yield and purity in the final product were 80.32% and 99.91% for fructose and 90.13 % and 92.34% for glucose, respectively.
