ABF 4C is the ESL configuration of ABF technology, designed specifically for the ultraclean blow filling of PET bottles. It is a rotary ultraclean blow moulding machine (Airstar 4C) with an integrated ultraclean filler and capper.
After passing through a traditional oven, preforms are decontaminated internally and externally before the blowing phase. This is achieved in a single, safe and reliable process, using Vaporised Hydrogen Peroxide (VHP). The treatment - fully controlled in H2O2 concentration, temperature and injection time - provides full coverage of internal and external preform surfaces simultaneously, without risk of cross contamination. This treatment achieves up to 3 Log red with A.brasiliensis, according to the ESL specifications.
The system reduces the use of chemicals and doesn’t need any water in production. Energy usage is kept to a minimum by the elimination of air conveyors and rinsing carrousels. The whole system is more compact than traditional technology and requires fewer operators.
ABF 4C is an extremely flexible system that can blow and fill up to 48,000 bottles per hour on 500 ml bottles, and operates at different levels of decontamination appropriate for each product: this allows products with different shelf-lives, low acid and high acid ESL beverages, to be filled on the same system.
