摘　　要：为了解决熟食品真空预冷过程中,封闭式捕水器不易清洗,自来水补水不均匀,空气回压导致二次污染等问题,设计了一种集冷却、补水、杀菌、回压一体化的全自动新型真空预冷机。采用罗茨-水环真空机组解决了封闭式捕水器的弊端;采用小分子水替代自来水,改善补水的不均匀问题;采用臭氧发生器设计臭氧回压模块,解决了空气污染问题。根据初始性能参数,对设备进行了理论计算和选型。改进设计的的新型真空预冷机易于清洗、补水均匀,有效解决了常规真空预冷机在工业应用中存在的问题,具有实际应用价值。In order to solve the problem of vacuum pre-cooling of cooked food that closed-type water trap is not easy to clean, the tap water replenishment is not uniform, the air back pressure causes secondary pollution and so on, a new set of cooling, replenishment, sterilization, back pressure integration automatic vacuum pre-cooling machine was designed. Roots-water ring vacuum pump unit was used to solve the shortcomings of closed-type water trap; Small molecules of water was used to improve the replenishment of non-uniform problems; ozone generator was adopted to design an ozone back pressure module to solve the air pollution problems. According to the initial performance parameters, the equipment was calculated and selected. This improved design solved the problems of conventional vacuum pre-cooling machine in industrial application effectively, and had practical application value.
