Get Close to WONE's UVC Tunnel Disinfection Machine
In the demanding world of food processing, surface hygiene is a non-negotiable requirement. Chemical disinfectants, while effective, leave residues, require rinsing, and can be inconsistent.
Enter the WONE ESD-T60 UVC Tunnel Disinfection Machine—a conveyor-based system that uses ultraviolet-C light to deliver fast, non-chemical, residue-free surface disinfection.
Let's see the machine, exploring its design, operation, and how it solves the most persistent surface hygiene challenges in food factories, all while meeting the rigorous standards of GB 28235
-2020, Codex Alimentarius, and BRCGS Issue 9.
What is the WONE ESD-1200A UVC Tunnel?
The WONE ESD-T60 is a tunnel-style surface disinfection machine designed for continuous, automated disinfection of objects passing through on a conveyor belt. It is built for the food industry,
where chemical residues on food surface, packaging, tools, and equipment are unacceptable.
How Does UVC Tunnel Disinfection Machine Work?
The ESD-T60 operates on a simple yet effective principle: expose the surface of an object to high-intensity UVC light for a controlled duration.
1. Conveyor Feed:
- Objects are placed on the conveyor belt, which moves them through the tunnel at an adjustable speed.
2. UVC Exposure:
- Inside the tunnel, arrays of UVC lamps (typically emitting at 253.7 nm, the peak germicidal wavelength) irradiate the surface of the object from multiple angles.
3. DNA Damage:
- The UVC energy penetrates the cell wall of microorganisms (bacteria, viruses, fungi, spores) and damages their DNA, preventing replication. This is a physical process—no chemicals are used.
4. Exit:
- The disinfected object emerges from the tunnel, ready for use or further processing, with zero chemical residue.
The touchscreen control panel allows operators to set timer functions, and log operational data for audit purposes.
Why Choose the WONE ESD-T60?
1. Non-Chemical, No Residue
The most significant advantage. UVC disinfection leaves no chemical residue, no rinse requirement, and no risk of tainting the product. This is critical for RTE foods, dairy, and beverage
applications where even trace chemicals can affect taste or safety.
2. High Throughput and Consistency
The conveyor system processes items at a consistent speed, ensuring that every object receives the same UV dose. This eliminates the variability of manual disinfection and dramatically
improves throughput—up to thousands of items per hour.
3. Hygienic Design
The UVC disinfection machine is built with 304 stainless steel and features smooth, cleanable surfaces. The control panel is designed for easy cleaning, and the tunnel interior is accessible for
maintenance. The machine complies with the hygienic design principles required by EHEDG and 3-A SSI.
4. Verifiable Performance
According to GB 28235-2020 Table 3, UVC tunnel disinfection can achieve a ≥3.00 log reduction for Staphylococcus aureus and E. coli on object surfaces. The ESD-1200A's real-time
monitoring and data logging capabilities provide auditable evidence of performance.
5. Safety Features
The machine is equipped with safety interlocks---the UVC lamps will not operator exposure to harmful UV radiation. It also includes overload, short-circuit, and leakage protection.
