1. The Problem: How H5N1 Spreads on a Processing Line

Influenza viruses are lipid-enveloped and can survive on stainless steel, plastic conveyor surfaces, and in refrigerated air for extended periods. Key contamination vectors in a typical facility include:

• Conveyor belts and sorting equipment: Continuous cross-contamination between raw and finished product zones.
• Air handling units: Recirculated air can distribute viral particles across large floor areas.
• Storage and packaging rooms: Low-temperature, high-humidity environments that preserve virus viability.
• Worker touchpoints: Handrails, control panels, and packaging machinery.

The challenge is that these surfaces must be disinfected continuously, without halting production, and without leaving chemical residues that could contaminate food products.

2. Why Traditional Methods Fall Short

None of these approaches satisfy the dual demand of inline + continuous (24/7) + residue-free disinfection that modern biosecurity protocols require.

3. The Tianhui Solution: Solid-State UVC LED Disinfection Engines

Tianhui provides modular, embeddable UVC LED engines designed specifically for OEM integration into food processing equipment.

3.1 Peak Wavelength Precision (265nm/275nm)

Sterilization efficacy peaks at 265nm, where viral DNA/RNA absorbs UV energy most efficiently. For low-ozone and long-running applications, 275nm provides a balanced profile with reduced ozone generation, preferred for food-contact environments. Tianhui employs ±3nm precision binning, ensuring every module delivers consistent, verifiable germicidal performance — critical for facilities that must document inactivation rates to international buyers.

3.2 100% Mercury-Free & Global Compliance

Our solid-state modules contain zero mercury, aligning with the Minamata Convention and strict international food-safety and environmental standards (RoHS, CE). This removes export barriers and simplifies environmental audits for producers selling into regulated global markets.

3.3 Industrial Reliability: 50,000-Hour Service Life

Through Full Inorganic Encapsulation — featuring AlN (Aluminum Nitride) ceramic substrates and quartz glass lenses — Tianhui modules resist the "yellowing" degradation that shortens ordinary LED life under intense UVC exposure. The result is a stable 50,000-hour (L70) operational lifespan, up to 5x that of mercury lamps, with dramatically lower maintenance costs.

3.4 Designed for Inline Integration

• Air sterilization: Modules embed into HVAC ducts and air handling units for continuous air purification.
• Surface sterilization: Linear arrays mount above conveyor belts, providing controlled dose (irradiance × exposure time) irradiation of product surfaces and equipment.
• Compact footprint: Flip-chip architecture reduces module volume by up to 60%, enabling integration into space-constrained OEM designs.

3.5 Intelligent Safety

Optional PIR (human proximity) sensing automatically shuts down UVC emission when personnel approach, while optional enclosed light-chamber designs ensure zero UV leakage — meeting safety requirements for human-occupied facility zones.

5. Engineering Support for OEM/ODM Partners

Tianhui acts as an engineering partner, not just a component supplier:

• Optical simulation reports: We model UV dose distribution for your specific equipment geometry.
• CAD integration files: Complete mechanical drawings for seamless embedding.
• Rapid prototyping: Small-batch samples for on-line validation, flexible MOQ.
• Documentation: English manuals, test reports, and certification documents (CE, RoHS, FDA-compliant data).

6. Why Tianhui

With 23+ years of dedicated UV LED engineering, Tianhui is a validated supply-chain partner to Tier-1 global brands including GREE, Haier, Midea, and Audi. We bring the same precision manufacturing and quality discipline to food safety disinfection that we deliver to the world's leading appliance and automotive manufacturers.
