This paper based on PLC for the UHT sterile machine computer control system design program, sterile machine in the engineering project is widely used, combined with the application of other industries, is put forward based on PLC UHT sterile machine braking control system. The working process is divided into four sterile machine for feeding, most of sterilization, cooling filling and CIP clean, in this thesis application omron PLC program compiling, and use PLC to control the sterile tank to cleaning sterilization, realized the automation control system sterile cans, better for through the PC to control the operation of equipment. Through the use of configuration king to achieve the working process of the real-time monitoring, make the whole process of the be clear at a glance, and better realize the automation Adopting PLC to control from the sterilization to the CIP cleaning, enables the control of tank system automatic, not only for labor productivity increasing, for aseptic performance stable, the degree of automation and production boosting are all full of profound significance, but also for the development of aseptic packaging technology plays a good promoting role.
