Mercury-Free UV LED Sterilization Tunnel for Food Packaging Lines

Composition of Production Line

This system is a self-contained, in-line processing module. A standard integrated production line includes:

1. Infeed Conveyor: Food-grade stainless steel wire mesh or belt with adjustable speed control.

2. UV-C LED Irradiation Chamber: Enclosed stainless steel housing with high-power UV-C LED array modules.

3. Agitation/Turning Mechanism (Optional): For irregular packaging, an internal automatic turning system can be integrated to ensure all surfaces receive uniform exposure.

4. Outfeed Conveyor.

5. Intelligent Control System: Integrated electrical cabinet with HMI (Human-Machine Interface), UV intensity sensors, and operation timer.

Product Description

This is an advanced in-line Ultraviolet (UV) sterilization tunnel designed for surface disinfection of various food packaging (e.g., plastic cups, bottles, films, boxes) immediately before filling and sealing. It replaces traditional mercury lamps with high-performance 280nm UV-C LEDs as the germicidal source. It instantly destroys microbial DNA/RNA, achieving a sterilization rate of up to 99.9%. The system eliminates risks of mercury contamination and requires zero warm-up time, offering a safer, more energy-efficient, and eco-friendly solution.

Technical Parameters

Application

• Pre-fill Packaging Disinfection: Internal sterilization of plastic cups, bottles, cans, boxes, and trays before filling.

• Packaging Material Treatment: Surface treatment of sealing films, lids, and foil laminates.

• Seamless Line Integration: Easily integrated into automatic filling, capping, and sealing production lines.

Customization

We understand production lines are unique. Our UV sterilization equipment is highly customizable to meet your specific needs:

• Dimensions & Power: Tunnel length, width, and UV intensity can be tailored to your line speed and required microbial log reduction.

• Conveyor Type: Choice of mesh, belt, or roller conveyor to suit your product.

• Special Configurations: Integration of turntables, multi-sided irradiation, or specialized housing for specific container shapes.

Key Features

• Mercury-Free & Instant-On: UV-C LEDs provide immediate full-power output, enhancing safety and operational efficiency.

• Energy Efficient & Low Heat: Consumes significantly less power than conventional mercury lamps and emits minimal heat, protecting heat-sensitive packaging.

• Precise Digital Control: Real-time monitoring and adjustment of UV dose via user-friendly HMI.

• Robust & Hygienic Design: Constructed from high-quality stainless steel, easy to clean and maintain, suitable for harsh washdown environments.

Support and Services

• Pre-Sales: Technical consultation and solution design.

• Installation: On-site or remote installation guidance and commissioning.

• Training: Comprehensive operation and safety training for your staff.

• After-Sales: 24-month warranty on main components, spare parts supply, and access to technical support.

Packing and Shipping

• Packing: The equipment is securely packed in an export-worthy wooden crate with foam and waterproof inner lining to prevent damage during transit.

• Shipping: We handle documentation and arrange sea or air freight to major global ports. Incoterms (FOB, CIF, DAP, etc.) are negotiable.

FAQ

• Q1: What is the lead time for a standard and a customized unit?

  • A: Standard units ship in 15-20 business days. Lead time for customized units depends on specifications and will be confirmed upon order.

• Q2: Do you provide a performance validation report?

  • A: Yes. Each unit can be supplied with a third-party test report verifying the UV dose output at the specified conveyor speed.

• Q3: How do I determine the required UV dose and tunnel length for my application?

  • A: Our engineers will assist you based on your target microorganisms, packaging material, and desired line speed. We can also conduct lab tests if needed.

• Q4: Is this equipment certified?

  • A: The electrical system is CE/UL certified. Other regional certifications can be discussed as part of the customization process.

• Q5: What maintenance is required?

  • A: 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.
