Description
本发明涉及植物深加工产品的除钙镁离子领域,具体地指一种植物深加工产品的除钙镁离子的方法。
植物深加工产品,比如甜菜糖蜜、含木糖的造纸废液、玉米芯生产木糖、甘蔗渣生产木糖等,都含有大量的钙镁离子,钙镁离子的存在,对生产过程有很多不利影响。比如,甜菜糖蜜的CaO含量约为0.15-0.7%,甜菜糖蜜用于谷氨酸的生产中,钙会影响谷氨酸的结晶,在废水的处理中,会使蒸发器结垢,影响蒸发的效率。因此,在工业生产中,植物深加工产品除钙镁离子,对加工过程非常重要。
常用的植物深加工产品除钙镁离子的方法有:
1)离子交换法:物料通过阳树脂,钙镁离子被钠离子交换,树脂饱和后,用氯化钠溶液再生。但是这个方法用于植物提取物的脱钙镁,有很多缺陷。植物提取物一般钙镁含量很高,软化树脂很快饱和,需要频繁的再生,会产生很多废水,特别是很多物料色素含量很高,比如甜菜糖蜜、含木糖的造纸废液等,这些有色的废水很难处理。
2)化学法,比如,在甜菜糖蜜软化中常用的纯碱法,加入纯碱后,会将甜菜糖蜜的PH值从中性,变为碱性,而甜菜糖蜜用于发酵,一般都是在酸性条件下,因此,还需要加酸,将pH值调到酸性,在这个过程中,即增加了成本,又容易产生一些副反应。
因此,由上可知,上述两种方法均不是最佳的工业化生产方案,迫切需要一种适用于植物深加工生产,且经济适用的去除植物深加工产品中钙镁离子的方法。
