During egg processing and packaging, reusable plastic egg trays are constantly exposed to egg liquid, eggshell fragments, and other contaminants. When selecting an egg tray washer machine, companies consider not only cleaning performance but also whether to incorporate UV or ozone treatment systems. More disinfection features aren't necessarily better; the key is whether the equipment meets actual hygiene requirements and integrates effectively with existing cleaning processes.
Why Do Egg Tray Washer Machines Need Disinfection Capabilities?
1. Cleaning and Disinfection Address Different Issues
Cleaning primarily removes egg liquid, dust, and other visible contaminants; disinfection, on the other hand, targets microbial control and requires meeting specific, validated treatment conditions. If a significant amount of organic residue remains on the surface of the egg trays, the effectiveness of subsequent disinfection may be compromised.
Therefore, when selecting an egg tray washer machine, you should first confirm whether processes such as pre-rinsing, main washing, and rinsing can effectively remove contaminants. Only then should you determine, based on your facility's hygiene management requirements, whether a separate disinfection stage is necessary.
2. Confirm Actual Hygiene Objectives
Egg tray turnover rates, contamination levels, and subsequent usage methods vary from facility to facility. Before purchasing, clearly identify the hygiene risks that need to be controlled, the applicable standards, and whether a validated disinfection procedure exists. One cannot assume that egg trays have met specific hygiene standards simply because the plastic egg tray washer is equipped with ultraviolet (UV) or ozone technology.
What Is the Difference Between UV and Ozone Systems?
1. UV Treatment: Focus on the Irradiation Range
UV systems can be used for specific surface treatment scenarios, but their effectiveness is influenced by irradiation intensity, exposure time, surface cleanliness, and any obstructions. Egg trays have numerous recesses; if certain areas cannot be directly exposed to effective irradiation, inadequate treatment may result.
Therefore, before installing a UV module, one should verify the installation location, irradiation coverage, equipment safety measures, and whether the actual egg tray structure is suitable.
2. Ozone Treatment: Focus on Concentration and Contact Conditions
Ozone has oxidizing properties and can be used in properly designed and validated treatment systems. However, its application requires consideration of concentration, contact time, material compatibility, exhaust gas treatment, and personnel safety. Ozone is not suitable for direct use in general cleaning areas without proper safety design.
Companies should require suppliers to explain the ozone system's operating principles, safety measures, and validation criteria, rather than making decisions based solely on whether the option is available.
How to Determine Whether to Add a Disinfection Module?
1. Determine Based on the Cleaning Process and Tray Application
For standard, reusable plastic egg trays, prioritize confirming whether the configuration—including multi-angle spraying, hot water washing, rinsing, and filtration systems—meets actual needs. If the facility's hygiene control program requires additional disinfection, then evaluate UV, ozone, or other validated treatment methods.
LONKIA's egg tray washer machine can be configured according to tray specifications, processing capacity, and production layout. When purchasing, clearly identify which features are part of the standard configuration and which are optional, and confirm that the specific model supports the required modules.
2. Verify Treatment Effectiveness Through Practical Testing
Before accepting the egg tray washing machine, it is recommended to conduct tests using actual egg trays and typical stains to check cleaning effectiveness in areas such as grooves and edges, and to verify disinfection effectiveness in accordance with applicable hygiene protocols. Additionally, confirm the equipment's processing capacity, operational stability, maintenance requirements, and safety measures.
Conclusion
Whether a UV and ozone system is necessary depends on the company's hygiene objectives, tray usage conditions, and validated treatment protocols. When selecting an egg tray washer machine, first ensure that the basic washing process is properly designed, then evaluate whether additional disinfection modules can address specific issues. By verifying equipment configurations, validating actual performance, and clarifying maintenance requirements, companies can select an egg tray washing solution that best meets their production needs.
