摘要
甘蔗糖蜜中含有大量无机盐,其中的钾盐使糖蜜呈涩味。试验通过离子交换膜电渗析法对甘蔗糖蜜进行脱盐处理。结果表明:电渗析对糖蜜脱盐有良好的效果,在工作电压为30V,流量70 L/h,糖蜜浓度为25°Brix时,糖蜜的电渗析脱盐精制脱盐率达到77.35%,脱钾率达到86.37%。
Plenty of mineral salts were contented in sugar cane molasses, which played an importance role in the taste of astringency, expecially the potassium salt. In present study, ion-exchange membrane （IEM） mediated eleetrodialysis （ED） was applied to desalinate the sugar cane molasses. The removal rate of inorganic salt and potassium salt were 77. 35% and 86. 37% respectively under the optimized conditions of voltage 30 V, flow rate 70 L/h, density 25°Brix.
