气浮清净工艺处理甘蔗糖液的试验研究

对亚硫酸法清净甘蔗糖液中应用的糖浆气浮、清汁气浮、预灰汁气浮、中和汁气浮等几种气浮清净工艺进行了试验研究,分析了气浮工艺的可行性,并探讨了糖浆气浮清净工艺的条件。结果是糖浆气浮、清汁气浮、中和汁气浮都有较好的清净效果,糖浆气浮适宜工艺条件是:磷酸加入量为200～300mg/kg,上浮糖浆pH6.4～6.6,上浮糖浆温度80～85℃。

Experimental Study of Flotating Purification Process of Cane Juice

An experiment was designed to study the application of several flotating purification processes, the cane syrup flotation, purified juice flotation, preliming juice flotation, and neutralized juice flotation in the sulfite purification of cane juice. The feasibility of the floatation process was analyzed, and the Conditions of cane syrup floatating purification process were discussed. The results showed that they have a good clean effect in the cane syrup flotation, purified juice flotation, neutralized juice flotation. Optimum conditions are the quantity of phosphoric acid as 200～300 mg/kg, cane syrup pH 7.5, cane syrup temperature 80～85 ℃.
