【Preface】

This system is an integral tunnel structure, divided into preheating area, high temperature sterilization area, cooling area of three parts, using hot air laminar flow disinfection principle for the container for short time high temperature sterilization. It is suitable for drying and sterilizing ampoule bottles, antibiotic bottles, oral liquid bottles, and other medicinal glass bottles. The system adopts advanced PLC man-machine interface control system, through the man-machine interface control, in addition to monitoring the working condition of the machine, to ensure the production process requirements. It can also be combined with the cleaning equipment and the filling and sealing equipment to control the working condition, and show the cause, location and simple elimination methods of the fault. And also can automatically record the temperature and graph.

【Text】

The electric control system of the tunnel oven system is mainly composed of three parts: temperature control, power transmission and report data, which make it meet the following technological requirements:

◆Equipped with the device of preventing spontaneous combustion in high temperature section of power failure, no fire hazard

◆The process parameters such as heating and running are set in advance

◆Parameter status display, automatic printing records

◆Circulating air flow can be adjusted to ensure uniform temperature in the box

◆Temperature measuring points are provided in the box and the box mouth

◆The machine is designed according to GMP requirements

【System structure】

1、HMI：PSM101PA

2、PLC：Host DPH60Y24R+PT module DPH-4AD-PT+TC module DPH-4AD-TC

3、Frequency converter: the number of VFT series economic frequency converter

【System specifications】

       Winmo DPH60Y24R high performance PLC as the control core of the system, centralized collection of oven preheating area, high temperature area, compensation area of the temperature, and with PID function to accurately control the temperature of each part. With independent RS485 serial port communication, the disorder can be controlled by Modbus communication through separate expansion, and the high-speed data exchange platform between PLC and various frequency converters is built perfectly, and the control parts are dynamically adjusted with the precision of 0.01Hz.

      At the same time, combined with the powerful expansion ability of Winmo DPH series PLC, it provides 4-channel TC data conversion and 4-channel PT temperature conversion, realizing the temperature acquisition of various sensors on site, highly ensuring the real-time and effectiveness of SV data.

      Supplemented by PSM101PA size touch screen, with a friendly interface, rich data manifestation form, perfect alarm control and powerful curve, report function, very good data display, data printing, data backup and other follow-up processing conditions.
