Research on Dry Mixed Control System of Milk Powder Based on MES

Abstract

In order to avoid the risk of quality in the various production processes of milk powder mixed, to achieve control and traceability of the whole process in milk powder production, we set up a small MES system based on dry mixed 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 sterilization, 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 interface, fast response speed, and provides a practical basis on the further research and application of MES system in food industry such as milk powder.
