摘　　要：用臭氧发生器制取高浓度臭氧气体,经高效涡旋气-水混合泵与水循环混合溶解臭氧而取得高浓度的臭氧水,然后把高浓度臭氧水持续地送入快速制冰机中制成鳞片状的臭氧冰。通过对影响制取臭氧冰浓度的臭氧气体流量、水温、混合压力、水pH和水质等条件进行研究,最终确定臭氧冰的生产工艺。实验结果表明,在水的pH为4.0,水温接近0℃,臭氧气体流量2.5L/min,混合泵出水压力0.2MPa的条件下进行循环混合,能制出高浓度的臭氧水和臭氧冰,所制得臭氧冰的臭氧浓度达16.7mg/L。High concentration ozone,produced by ozone generator,was mixed with water by vortex pump to obtain the high concentration ozone water,and then the high concentration ozone water was inducted continuously to the fast ice-making machine,the flake ice was made.The impacts of flow rate,water temperature,mixing pressure,and water pH value and water quality were studied.The results showed that when the water pH reached 4.0,the water temperature closed to 0℃,the ozone gas flow rate was 2.5L/min,pressure of mixing pump was 0.2MPa,the high ozone concentration of water and ice could be produced,its concentration reached 16.7mg/L in the ice.
