High-Throughput Cage Washing System with Advanced PLC Control for Animal Research Facilities

Project Overview

A large-scale animal research center required a high-throughput, fully automated cage washing solution capable of supporting continuous operation while meeting strict hygiene and biosecurity standards. Based on the client's high daily processing volume and workflow requirements, our engineering team designed and delivered a customized tunnel cage washing system built for 24/7 operation and seamless integration into the facility's cage handling process.

System Architecture and Workflow

The system combines pre-washing, intensive washing, rinsing, and high-temperature drying within a continuous conveyor structure, ensuring fast turnaround and consistent cleaning performance. Automated loading and unloading sections minimize manual handling and improve overall efficiency, allowing laboratory staff to focus on higher-value research activities.

Core Technology Components

To ensure long-term reliability and precise control, the system is equipped with internationally recognized components selected for their proven performance in demanding industrial environments:

Cleaning and Disinfection Technology

High-pressure spray technology combined with controlled thermal disinfection effectively removes organic and inorganic contaminants. The system supports the strict barrier conditions required in modern animal facilities, including SPF-level environments where contamination control is critical to experimental validity.

Optional Configuration Modules

• HMI Touch Screen Interface - User-friendly operation panel with intuitive controls, reducing operator training time and minimizing human error
• Data Monitoring and Traceability - Real-time logging of wash cycles, temperature curves, and system diagnostics to support facility management and regulatory compliance documentation
• Energy- and Water-Saving Design - Optimized recirculation and heat recovery modules that significantly reduce operational costs over the equipment lifecycle
• Pre-Slag Removal Device - Automated debris separation to protect downstream spray nozzles and extend maintenance intervals
• Automatic Disinfectant Proportioning - Precision chemical dosing system for consistent sanitization results

Client Results and Performance Metrics

After installation and commissioning, the client reported measurable improvements across key operational indicators:

Conclusion

This project demonstrates our capability to deliver high-performance, customizable, and globally competitive cage washing systems tailored to the specific needs of large-scale laboratory animal facilities. By combining advanced automation, internationally certified components, and flexible configuration options, we help research institutions achieve higher throughput, lower operating costs, and rigorous biosecurity compliance.
