Krones Inc.'s booth at NPE2012 in Orlando featured the SuperPET bottle-to-bottle recycling process and the latest generation of the Contiform PET stretch blow molding machine.
Krones has completely revamped the blow molding module for the Contiform 3, the third generation of the Contiform S/H series. The linear oven of the S/H series has been enhanced to cut energy consumption.
Designers also increased the amount of output per station, reduced total air consumption, shortened changeover time, improved access to the machine and made it easy to use, according to the company.
The Contiform 3 comes in sizes ranging from eight to 36 blow molding stations, reaching an output of up to 81,000 containers an hour.
By mid-2012, heat-set and small-cavity versions of the Contiform will be available, as will the integration of Krones' Contipure for decontamination of preforms.
Since Contiform was introduced 14 years ago, Krones officials said the company has installed about 1,500 of the blow molding machines worldwide.
Also at NPE, held April 1-5, Krones highlighted SuperPET recycling technology, which complies with Food and Drug Administration rules. PET bottles are recycled into new bottles and food containers.
SuperPET completely removes foreign materials such as labels, adhesives, dirt and other contaminants, according to Krones.
Both the flake washing and decontamination processes are harmonized to ensure the production of food-grade PET.
The washing technology includes several processes, including a dry cleaning phase and a wet cleaning phase, where foreign material is removed.
