摘要
为了规避在奶粉干法生产过程中各个环节存在的质量风险,实现对奶粉生产整个过程的控制与追溯,该文建立了一套基于奶粉干混和气力输送工艺条件下的小型MES系统。系统由分布式触摸屏计算机、条码扫描设备和PLC构成,采用基于客户/服务器(Client/Server)的SQL数据库结构,实现杀菌、配料、干混、气力输送及包装环节配料的品种、数量(重量)及人员信息的验证及与控制,以及前后工序间的工序流程控制。实际应用表明,该系统人机交互界面友善、信息响应速度快,为奶粉等食品类工业生产的MES系统的进一步研究与应用提供了实践基础。
In order to avoid the risk of each link in the production process of dry milk powder quality to achieve on the milk production of the whole process control and traceability,we establish a set of small MES system based on dry mixing powder and pneumatic conveying technology. This system consists of distributed touch screen computer, bar code scanning equipment and PLC,which using SQL database structure based on client/server to achieve steriliza- tion,ingredients,dry mixing,varieties of pneumatic conveying and the variety and quantity of ingredients （weight） in the packaging link and the verification and control of personnel information,as well as the process flow control in the front and back of the process. The practical application shows that this system has a friendly man-machine inter- face,fast response speed,and provides a practical basis on the further research and application of MES system in food industry such as milk powder.
