Recently, UVL completed a customized UV disinfection project for a major dairy manufacturer specializing in yogurt production. The goal was clear: sterilize plastic bottles directly on the conveyor line without halting production, ensuring reliable microbial control before filling.
Challenge: Continuous Disinfection in Tight Spaces
After an on-site technical evaluation, our engineers identified the ideal integration point along the conveyor. The line speed and required UV dose (35 mJ/cm²) were used to calculate the optimal installation parameters. The solution: a compact 540W UV system housing three 180W quartz UV lamps, mounted within a precision-engineered stainless steel enclosure.
System Features and Execution
- Guided mounting rails for seamless alignment with existing equipment
- Custom-built frame and electrical cabinet included
- Rapid installation: the full system was installed and operational in a single day during scheduled maintenance, ensuring no production downtime
- Pre-validated UV output matched to container material and line speed
The result: yogurt bottles now arrive at the filling zone already sterile, significantly reducing spoilage risks, improving shelf life, and enhancing product consistency.
Built-in Safety for Food Industry Standards
To meet the strict hygiene protocols of the food sector, we incorporated several safety and performance features:
- Shatterproof UV lamps with protective coating for safe operation near food packaging
- Real-time monitoring system that shuts down the conveyor if a lamp fails
- Delayed start logic ensures UV exposure begins only when the lamps reach full output
- Flexible UV-blocking silicone shields protect workers from stray light exposure
Turnkey Solution — or Modular Design for DIY Integration
This turnkey installation demonstrated our full-cycle capabilities: from dose calculations and enclosure design to on-site commissioning and validation.
But we also support self-installation projects. You provide your conveyor specs — we’ll engineer the UV disinfection lamp, develop the housing, and deliver a ready-to-mount solution tailored to your production line.
If your operation demands UV packaging sterilization that works in real time, integrates seamlessly, and meets food-grade safety expectations — we’re ready to help.
