摘　　要：为考察水力空化强化亚硫酸钙沉淀吸附糖液中非糖分的作用,通过涡轮产生空化并作用于亚硫酸法糖液澄清过程,考察了空化处理时间、涡轮出口压力、溶液温度、溶液浓度等因素对糖液简纯度的影响。结果显示:涡轮空化作用能够有效地强化亚硫酸钙沉淀吸附糖液中的非糖成分,明显提高糖液的简纯度;涡轮空化强化亚硫酸钙吸附非糖分的最佳工艺条件为空化处理10s、出口压力0.1MPa、溶液温度50℃、溶液浓度15°Bx,在此条件下糖液的简纯度为86.99%,明显高于无水力空化条件下澄清糖液的简纯度(86.18%)。研究结果表明了水力空化能够有效强化亚硫酸钙吸附糖液中非糖分。The effects of hydrodynamic cavitation on the adsorption of non-sugar on calcium sulfite were studied. The hydrodynamic cavitation generated with the turbine were applied to the syrup, and the effects of cavitation treatment time,turbine outlet pressure, solution temperature and solution concentration on the apparent purity（AP） of syrup were investigated.Results showed that the hydrodynamic cavitation improved the AP of syrup effectively. It was found that the optimal conditions using turbine cavitation adsorption of non-sugar on calcium sulfite.. cavitation treatment time was 10s,the turbine outlet pressure was 0.1 MPa,the solution temperature was 50℃, and the solution concentration was 15° Bx. Under the optimal conditions the AP of syrup increased from 86.18% to 86.99% ,increased by 0.81% compared with that without hydrodynamic cavitation treatment.
