Preform neck sterilization could be done by integrating this equipment on the preform chute upstream of the blowing step(preform necks), or on the conveyor upstream of the filler (bottle necks).
The decontamination levels obtained on preform necks achieve a 3 - 4 log microbial reduction in bacteria and molds.
The preform neck (internal and external) is decontaminated by pulsed light.
The body of the preform is decontaminated when it passes through the oven at the blowing step.
