Decowell PLC Solution Empowers High-Efficiency, Stable, and Intelligent Production on a Large-Scale Rice Packaging Line

Decowell PLC Solution Empowers High-Efficiency, Stable, and Intelligent Production on a Large-Scale Rice Packaging Line

In modern food processing, packaging operations demand precise equipment control and highly stable systems. To address key challenges faced by a client—including excessive vibration, frequent false triggers, poor sealing, and electromagnetic interference—Decowell provided a comprehensive automation control solution based on the MTC series PLC and remote I/O modules. The result: significantly improved system reliability and production efficiency.

Project Background

Large-scale rice packaging lines typically include feeding, weighing, packaging, and sealing systems. To ensure accurate bag weight, proper sealing, and compliance with hygiene standards, the control system must offer high responsiveness, strong anti-interference performance, scalability, and easy maintenance.

Decowell Solution

Decowell deployed an automation architecture using MTC series PLCs and remote I/O modules, fully replacing traditional wiring systems to enhance responsiveness and system stability.

Key Highlights:

• Annual Output: Over 2 million units

• Core Components: MTC-CEC-A series valve island with rapid response and precise control

• Plug-in Solenoid Valves: Shock-resistant, false trigger-proof, and EMI-resistant

• Multi-Zone Pressure Control: Single I/O module handles multiple packaging specifications

• Layered Control Architecture: From information layer – PLC – execution layer – sensing layer; highly scalable and easy to maintain

Before & After Comparison:

• Original System: Complicated wiring, delayed response, and high failure rate

• With Decowell:

  • Significantly improved response speed

  • Enhanced system stability and flexibility

  • Easy maintenance with true "plug-and-play" functionality

  • Over 30% improvement in overall efficiency

Industry Impact

This project demonstrates how Decowell's PLC systems enable smart upgrades for traditional food packaging lines. From rice to flour, grains to nuts, our solution is scalable and adaptable to a wide range of food processing applications. Decowell continues to drive intelligent, clean, and green manufacturing through technological innovation—actively contributing to the vision of "Made in China 2025."
