Mercury-Free UV LED Sterilization Tunnel for Food Packaging Lines
Product Overview
Advanced in-line Ultraviolet (UV) sterilization tunnel designed for surface disinfection of various food packaging immediately before filling and sealing. Replaces traditional mercury lamps with high-performance 280nm UV-C LEDs as the germicidal source.
Instantly destroys microbial DNA/RNA, achieving a sterilization rate of up to 99.9%. Eliminates risks of mercury contamination and requires zero warm-up time, offering a safer, more energy-efficient, and eco-friendly solution.
Production Line Composition
Infeed Conveyor: Food-grade stainless steel wire mesh or belt with adjustable speed control
UV-C LED Irradiation Chamber: Enclosed stainless steel housing with high-power UV-C LED array modules
Agitation/Turning Mechanism (Optional): For irregular packaging, ensures all surfaces receive uniform exposure
Outfeed Conveyor
Intelligent Control System: Integrated electrical cabinet with HMI, UV intensity sensors, and operation timer

Frequently Asked Questions
What is the lead time for a standard and a customized unit?
Standard units ship in 15-20 business days. Lead time for customized units depends on specifications and will be confirmed upon order.
Do you provide a performance validation report?
Yes. Each unit can be supplied with a third-party test report verifying the UV dose output at the specified conveyor speed.
How do I determine the required UV dose and tunnel length for my application?
Our engineers will assist you based on your target microorganisms, packaging material, and desired line speed. We can also conduct lab tests if needed.
Is this equipment certified?
The electrical system is CE/UL certified. Other regional certifications can be discussed as part of the customization process.
What maintenance is required?
Routine maintenance is minimal: regular cleaning of the quartz sleeves (if applicable) and the conveyor. The LED modules have a long lifespan with no scheduled replacement under normal use.
