Frequently Asked Questions
Q1: Can this UV-C tunnel sterilize both the inside and outside of a transparent clamshell container in a single pass?
A1: Yes. The upper-and-lower lamp array (dual-side option) irradiates the external surfaces from above and internal surfaces through the transparent material from below, achieving comprehensive, 360° coverage -- all within the same pass.
Q2: What is the typical UV dose required for a 4-log (99.99%) reduction of common foodborne pathogens on transparent packaging?
A2: A dose of 20-40 mJ/cm² generally achieves 4-log reduction for susceptible organisms like E. coli and Salmonella. More resistant pathogens may require 50-80 mJ/cm², while highly resistant spores can need 100-200 mJ/cm². Our systems provide adjustable dose control to accommodate these varying targets.
Q3: How does UV irradiation differ in effect between transparent and opaque printed packaging areas?
A3: Printed ink areas have reduced UV-C transmission. We recommend placing lamp arrays to preferentially treat transparent zones, extend dwell time, or configure higher-intensity emitters to compensate -- all achievable via customizable recipe adjustments.
Q4: Does the sterilization tunnel produce any harmful ozone?
A4: The optional 185 nm ozone-generating lamps can be entirely bypassed or excluded; our standard 254 nm UV-C lamps produce no significant ozone. Optional ozone-free lamp configurations are also available upon request.
Q5: What is the standard lamp replacement interval?
A5: Mercury lamps provide 8,000-10,000 hours of operation; LED-UV modules provide ≥20,000 hours to L70. The system tracks cumulative operating hours per lamp and alerts when replacement is due. Replacement can be performed without interrupting production line operation (hot-swappable lamp trays).
Q6: Can the system be retrofitted into an existing production line without major modifications?
A6: Absolutely. Conveyor height, width, control interface signals (dry contacts, Ethernet/IP, Profinet), and infeed/outfeed conveyor dimensions are fully customizable to match your existing line and upstream/downstream equipment. Retrofits are typically completed with minimal production downtime (2-4 days).
