【摘要】 研究了超细碳酸钙做为亚硫酸法糖厂糖汁澄清的晶核 ,对蔗汁澄清效果的影响。研究结果表明 ,在一定条件下加入超细碳酸钙可起到晶核的作用 ,更有利于沉降速度的提高 ,减少蔗汁在沉降池中的停留时间。同时 ,碳酸钙是一种良好的吸附剂 ,它能使更多的胶体和色素以及其它非糖分因被吸附而除去 ,有效地降低清汁色值和钙含量 ,并提高蔗汁的纯度。更多还原

【Abstract】 The sedimentation velocity of sugarcane juice clarification using over-fine calcium carbonate crystal for intensifying was studied. It will make sedimentation velocity faster and reduce the time of sugarcane juice sedimentation. In the same time, calcium carbonate crystal is a good adsorption as we know;it can remove more colloid, coloring matter and non-sugar contents. It also can reduce color value of sugarcane juice and calcium content, and increase purity of sugarcane juice.更多还原
