1 序文
真空均质乳化机（简称乳化机）首要运用于化工、医药、生物、食物等许多领域中非均相液一固和液一液多相体松散系统的混合。现在该设备在国内首要是选用传统的继电器控制系统构成，操作人员需求根据阅历和表面闪现输入指令或数据进行手动操作，主动化程度不高，一同控制系统存在操作繁琐、温度控制超调量大、能耗高级缺点。
2 乳化机的工作进程
2.1 工作原理
乳化机由乳化锅、水相锅、油相锅、真空设备、温度控制系统、电气控制系统等构成。
出产技术流程如图1所示［1，2］。油溶性和水溶性材料分别在油相锅和水相锅内熔化或溶解，温度通常坚持在80℃左右，将用水蒸气加热的油相和水相材料通过过滤器加至乳化锅内，以进行均质搅拌、乳化和真空脱气。然后，向夹套通入冷水，冷却到必定温度后，增加香精，继续冷却至恳求的温度间断搅拌，待恢复常压即可出料。
2.2 工作进程
（1）油相锅、水相锅进料后，发起油相、水相搅拌电机，在线设定油相、水相电机的转速；
（2）设定油相锅、水相锅控制温度后，发起油相锅、水相锅的温度控制；
（3）当油相锅、水相锅内材料初处理结束后，发起油相锅、水相锅出料泵，将初处理后的物料泵入乳化锅内；
（4）当油相锅、水相锅内的物料完全泵入乳化锅内后，出料泵间断工作。发起液压电机，垂直降低主搅拌器与均质搅拌器，当降低到位时，液压电机间断工作，然后手动旋紧密封阀；
（5）当真空乳化锅密封后，发起主搅拌、均质搅拌电机。转速将从零上升到用户的设定值，并可根据不一样的加工恳求，在线改动主搅拌、均质搅拌电机的转速；
