In modern pharmaceutical and chemical manufacturing, process automation and control accuracy are critical to ensure consistent product quality and regulatory compliance. Upgrading the electrical control panel and programming software of equipment such as the Granulation Line and VG (Vertical Granulator) Mixer plays a vital role in achieving higher efficiency, safety, and process repeatability.
This project involved a complete modernization of the granulation and mixing system’s control infrastructure, focusing on:
Replacement of outdated electrical panels
Integration of PLC-based control logic
Custom HMI design for enhanced user interaction
Re-programming of process sequences for optimized performance
The upgrade aimed to improve automation precision, batch consistency, and system reliability while simplifying operator control and maintenance.
The new control panels were engineered with:
PLC & HMI Integration: Transition from manual or semi-automatic control to a fully programmable system.
VFD Drives for Motors: Enabling variable speed control for granulators and mixers to match different product formulations.
Sensor Integration: Real-time monitoring of temperature, pressure, torque, and mixing speed.
Safety and Compliance: Panels designed to meet GMP and industrial safety standards with proper interlocks and emergency stops.
Custom PLC and HMI software were developed to automate and fine-tune every stage of the granulation process:
Automated Batch Sequencing: Controls wet granulation, drying, and mixing cycles with precise timing.
Recipe Management: Allows operators to store and recall multiple product recipes.
Real-Time Data Display & Alarms: Continuous monitoring of process variables with instant alerts for deviations.
Data Logging & Reporting: Batch data is recorded automatically for quality assurance and traceability.
Post-installation, the system underwent:
I/O and function testing to validate performance and interlocks.
Calibration of temperature, speed, and load sensors.
Operator and maintenance training to ensure smooth transition to the upgraded system.
Increased Production Efficiency: Reduced manual intervention and faster batch cycles.
Consistent Product Quality: Accurate control of mixing and granulation parameters.
Improved Safety & Compliance: Enhanced process interlocks and monitoring.
Ease of Maintenance: Simplified diagnostics and modular panel design.
The upgrade of the granulation line and VG mixer control systems demonstrates how modern automation can transform legacy equipment into smart, data-driven production assets. With improved reliability, precision, and compliance, manufacturers are better equipped to meet evolving quality and productivity demands in the pharmaceutical and chemical industries.
