UVC-Lock Disinfection Chamber

Safe UVC Surface Disinfection for Food, Packaging Materials, and Tools
In close collaboration between Kronen GmbH and sterilAir®, the UVC-Lock disinfection chamber was developed for UVC surface disinfection. The UVC-Lock offers a reliable and fast solution to reduce surface microbial load when transitioning into the hygiene area. The dry disinfection process occurs without heat or undesirable residues and additives. Thanks to highly effective UVC technology, we achieve excellent disinfection results in a short time. This allows for a compact design of the machine and its application even for sensitive products.

Products are either manually placed or fed via a processing line onto the conveyor belt and passed through a shielded area with UVC emitter tubes. The UVC-Lock enables 360-degree disinfection, with the efficient arrangement of UVC emitters ensuring an almost complete irradiation surface. The stainless steel mesh belt minimizes product shadowing from below. At the end of the conveyor, the disinfected product is transferred, for example, into the high-care area.

Versatile Applications:
The UVC-Lock is commonly used for surface disinfection of crates, tools, packaging materials (e.g., buckets or cans), food outer packaging (e.g., sausage casings), and fruit and vegetable products before further processing, such as cabbage heads or pre-peeled onions and carrots. The capacity varies depending on the product and contact time, which affects germ reduction. For instance, cabbage heads can be disinfected at a rate of up to 3 t/h with conveyor speeds ranging from 0.05 to 0.3 m/s. For transport crates (600 x 400 mm), up to 900 pieces per hour can be treated at a conveyor speed of 0.2 m/s.

Note: The disinfection of food is subject to country-specific legal regulations.
