| dc.description.abstract | This project presents the design and development of a Steam Sterilizer for Healthcare and
Industry Applications that integrates mechanical fabrication, electronic control, and software
automation into a unified system. The sterilizer was constructed with a stainless-steel pressure
chamber, heating elements, and safety valves, combined with sensors for real-time monitoring
of temperature and pressure. A microcontroller-based control board with PID algorithms was
implemented to maintain stable heating at the required set-point, ensuring accurate sterilization
conditions. Additionally, a SCADA system was developed to provide a user-friendly interface
for monitoring, control, database logging, and batch-wise report generation.
During testing, the system achieved a stable sterilization temperature of 121°C within 30
minutes, with pressure levels accurately tracked by both sensors and SCADA. The PID
controller effectively minimized overshoot and maintained consistent thermal regulation.
Validation with a Bowie-Dick test pack confirmed successful steam penetration and
contamination-free results, ensuring process reliability.
The project demonstrates a low-cost, reliable, and efficient sterilization solution suitable for
hospitals, laboratories, and small industries, offering an affordable alternative to costly
imported systems. | en_US |
