Challenge
Cleaning medical waste bins presents a unique set of challenges due to the nature of the contaminants and the need for reliable sanitation. The customer was managing high volumes of bins in multiple sizes, each requiring thorough cleaning to remove biological residue and ensure safe reuse.
Manual cleaning methods proved inefficient and inconsistent, creating bottlenecks and variability in cleanliness results. Additionally, the system needed to accommodate different bin heights and geometries while also processing lids in parallel. Achieving complete coverage, maintaining throughput, and ensuring repeatable sanitation standards required a fully automated and controlled cleaning solution.
Approach
Better Engineering engineered a custom conveyor parts washer designed specifically for high-volume medical waste bin cleaning:
- Implemented a continuous, belt-driven conveyor system with adjustable speeds, enabling throughput up to 200 parts per hour based on operational demand
- Integrated a heated, recirculated wash stage (S5) operating up to 180°F, powered by a 10 HP pump delivering approximately 200 GPM at 60 PSI for aggressive residue removal
- Designed a dual-lane configuration to process bins and lids simultaneously, ensuring proper alignment and full spray coverage for both components
- Included an optional heated drying stage (DH) reaching up to 250°F, allowing bins and lids to exit clean, dry, and ready for immediate reuse
- Constructed wetted components from 304 stainless steel for durability, corrosion resistance, and compatibility with sanitary applications
- Built a modular, expandable system to support future capacity increases and simplify installation
Results
The implementation of the conveyor parts washer transformed the customer’s cleaning operation from a labor-intensive process into a controlled, high-throughput system. Automation significantly reduced manual handling while improving consistency across all bin sizes and lid configurations. The high-temperature wash stage ensured effective removal of contaminants to support sanitation requirements, while the continuous conveyor design eliminated bottlenecks and maintained a steady production flow. Overall, the system delivered reliable, repeatable cleaning performance with improved operational efficiency.
Conclusion
By transitioning to a custom conveyor parts washer, the customer established a more hygienic, efficient, and scalable approach to cleaning medical waste bins and lids. The system’s continuous operation, high-temperature wash capabilities, and optional drying stage ensure that containers are consistently cleaned and ready for reuse without delays. With reduced labor demands, improved sanitation control, and the flexibility to expand alongside operational growth, the solution provides a long-term foundation for safe and efficient medical waste handling.
