CAPPING / CLOSURES 27 PET planet insider Vol. 15 company has established partnerships with a number of packaging plant sup- pliers who are interested in integrating Claranor technology into their offers, in place of hydrogen peroxide or con- tinuous UV treatment units. Around 80 sensitive beverage filling lines worldwide are now equipped with Claranor cap sterilisation units. Sensitive beverages, such as fruit based drinks with low preservative content, low carbonated soft drinks, flavoured waters, drinkable yoghurts and other drinks filled in ultra-clean condi- tions are very much aware of the need for packaging decontamination. Enterprises in these markets that have chosen pulsed light solutions include Hansa Heemann in Germany, which recently installed its fourth pulsed light cap sterilisation unit on a KHS new line, and Vilsa Brun- nen, which has three lines equipped with the Claranor solution. The technology The use of flash UV lights for microbiological decontami- nation was first developed in Japan in the 70’s and has since been widely tested in laboratory situations. Ultravio- let rays contained in intense flashes of white light emitted by Xenon lamps have been demonstrated to be effective as decontaminants against a wide range of microor- ganisms: bacteria, moulds, viruses, etc. The UV part (200 – 400nm) of the radiation included in the flash, brings about the destruction of microorganisms present on the product under treat- ment by a combination of a photothermic effect and a photochemical reaction. The absorption of UV rays by DNA provokes its modification, leading to the death of the microorganism. The decon- tamination level obtained depends on the number and power of the flashes applied and the nature of the surface being treated; it ranges from simple logarithmic reduc- tion to complete sterilisation.

The treatment equipment is com- posed of two main parts:  An electronics bay, which generates high power impulses from mains energy, through a capacitor. A control panel is used for observation and control of the process;  An optical cavity located in the opti- cal cabinet, fitted with one or several lamps and aluminium reflectors, specifically designed to homogenize and focus the light ray on the surface under treatment. An additional cooling system ena- bles the regulation of the temperature of the lamp’s water. www.claranor.com
