Abstract: 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 10 s, the turbine outlet pressure was 0.1MPa, the solution temperature was 50℃, and the solution concentration was 15° Bx. Under the optimal conditions the AP of syrup increased from 86.18% to86.99%, increased by 0.81% compared with that without hydrodynamic cavitation treatment.
