Reliable UVC surface disinfection of food products as well as packaging materials and tools

The flow-through lock for UVC surface disinfection was developed in close cooperation with KRONEN's partner sterilAir®. The UVC Lock is a reliable and quick solution for reducing surface contamination during transfer to the hygiene area. Dry disinfection takes place without heat exposure and without undesirable additives or residues. The highly efficient UVC technology leads to excellent disinfection performance with a short contact time. This also results in the compact design of the machine and its practical use, even for heat-sensitive products. 

The products are brought onto the conveyor belt manually or in a processing line via the infeed belt and are guided through a screened area with UVC emitter tubes. The UVC Lock enables disinfection from all sides, while the efficient arrangement of the UVC emitters ensures a virtually complete radiation area. The stainless steel mesh conveyor belt ensures the minimum possible shading of the product from below. At the belt outfeed, the disinfected product is discharged, for example into the high-care area.

A wide range of application options:

The UVC Lock is frequently used for the surface disinfection of boxes, tools, packaging materials (e.g. buckets or cans), outer packaging of food products (e.g. sausages), and fruit and vegetable products before further processing, e.g. cabbages or pre-peeled onions and carrots.

The capacity depends on the product and the contact time, which determines the degree of germ reduction. Cabbages, for example, can be disinfected at a rate of up to 3,000 kg/h at belt speeds of 0.05 to 0.3 m/s. If transport boxes (600 x 400 mm) are used, this figure increases to up to 900 units per hour at a belt speed of 0.2 m/s.

Please note: The disinfection of food products depends on the country-specific statutory regulations.

Benefits

The UVC-Lock disinfection lock from KRONEN has been optimized in terms of safety and simplicity in operation

Simple, safe operation

The handles with which the cover is closed and also simultaneously locked are positioned with ergonomic spacing. Opening is assisted by powerful gas pressure springs. The lateral contact protection at the belt infeed and outfeed ensures personnel safety. The fully enclosing housing with a belt cover is made of stainless steel; the triple plastic curtains on each side serve as a screen. The UVC Lock is equipped with safety switches to ensure that the emitters are switched off as soon as the cover is opened. The machine is operated via a switch panel. A touch screen display, which can be covered during the cleaning process, is offered as an option. The machine can also be operated from the high-care area thanks to the second control panel with an emergency stop switch on the belt outfeed side. When the belt is stopped, it continues to run until it is completely empty.

The UVC-Lock disinfection lock from KRONEN is easy to clean and service thanks to its sophisticated hygienic design

Optimized cleaning and hygiene

The fully accessible interior, the base frame made of round tubes and the cleaning mode, in which the belt runs with the cover open, enable fast and easy cleaning and maximum hygiene. The tube emitters comply with protection class IP 65, meaning that the UVC Lock can be completely foamed and rinsed with water. The tubes are welded into a Teflon tube, which serves as splinter protection. The screening curtains can be easily unhooked. Ballasts and electrics are accommodated in a separate box, and the lower emitters are installed in a pull-out drawer, which makes cleaning and replacement easier. The base frame is optionally available with casters as a mobile version.

The dry disinfection of surfaces using UVC technology makes the UVC-Lock disinfection lock from KRONEN safe, efficient and versatile

Effective UVC disinfection for flexible use

The surfaces of the products are subjected to a highly effective dry disinfection process using UVC radiation. In this process, the energy of the UVC light at a wavelength of 254 nm damages microorganisms and prevents their proliferation. The ingress of undesirable microorganisms into sensitive production areas can be reduced; the hygiene of objects and the shelf life of food products extended. The UVC disinfection unit is used to separate low-care and high-care areas. It is also suitable for locations with wet cleaning and for all usual temperature ranges between 0 and 40 degrees Celsius room temperature. (Fig. © sterilAir®)


Accessories

The UVC-Lock disinfection lock from KRONEN can also be equipped with low-pressure and hybrid tubes depending on individual requirements – the ideal equipment is calculated for the customer
Individual equipment with state-of-the-art UVC tubes from sterilAir®

The disinfection lock offers a large throughput capacity with highly efficient germ elimination. Either 12 or 20 ET 2236-4H low-pressure tubes are provided as standard. The machine is optionally available with 6 to 26 low-pressure tubes or alternatively with the even more powerful hybrid tubes, depending on the reduction in bacterial load and capacity to be achieved. After switching on the UVC Lock, the emitters are brought up to operating temperature in about three minutes such that full power is available before the machine is used. This is ensured by a time-delayed release of the conveyor belt. A long service life, low energy consumption and a low surface temperature characterize the UVC tubes from sterilAir®.

Close checks on the emitter tubes in the UVC-Lock disinfection lock from KRONEN is possible through integrated monitoring
Tube monitoring with data transmission

A simple tube check on the unit is possible via the inspection window on the front and back. An integrated tube monitoring system is available as an option. This allows each individual UVC tube to be monitored via the control box. The group values or individual values can be read out on a PC or a mobile device. This makes it possible to identify the output of the tubes and when they need to be changed. In addition, it is possible to read out other machine states such as running times or speeds.

The belt speed controller can be used to vary the capacity and contact time (i.e. degree of microbial load reduction) in the UVC-Lock disinfection lock from KRONEN
Belt speed regulation

The belt speed can be used to regulate the capacity and the contact time, which determines the extent of bacteria reduction. A frequency converter in the control box allows the adjustment of the belt speed. The belt runs at a fixed speed as standard, but a controller is available as an option to flexibly adjust the belt speed. 

The upper emitter tubes in the UVC-Lock disinfection lock from KRONEN are easy adjustable and thus optimally adaptable to anyproduct
Height adjustment of the upper tubes

If the disinfection lock is used for different products, the optionally available, tool-free height adjustment of the upper emitters is ideal. This enables you to set the minimum distance to the radiation source for each product, thus ensuring the optimal effect.

The belt of the UVC-Lock disinfection lock from KRONEN can also be reversed and thus transport products back or discharge them
Transport in both directions

If the lock is used between low-care and high-care areas, products can be discharged from the high-care area again with the optional right-left run. The UVC Lock is then used as a conveyor belt.
