PET BOTTLING: 100% CHEMICAL FREE PACKAGING STERILIZATION
le 30 déc. 2016
Claranor announces PET-preform sterilization, opening the way for 100% chemical free ultra-clean line
Despite having the Claranor chemical free solution for cap sterilization, owners of PET lines had no way to decontaminate preforms without chemical sterilants.
In collaboration with 1Blow, French manufacturer of blow-molding machines, Claranor has performed a series of microbial testing demonstrating a high killing rate on preforms while flashing the preform just after the oven.
The results are following:
|Preform neck + body||2.1||2.0
|Results in mean log reduction||Oven heating
(115 - 120°C)
(115 - 120°C)
In this combination of treatments, there is no effect of heat on the neck that remains cold, but where pulsed light is the strongest. On the contrary, the effect of pulsed light is total on the internal and external surface of the neck, and the rays arriving inside the body increase the effect of the heat.
The industrialization of this process is accessible, as the pulsed light reflector can continuously and instantly treat preforms passing from the oven to the blowing machine, with only 50cm straight section. The treatment can reach 100.000 bph.
The external surface of the preform is also decontaminated, body + neck.
OEM have shown great interest in this innovative patented solution previewed at the Petnology conference in Nuremberg the 8th of November and presented in Bangkok the 30th of November at the Aseptipak forum.
