FDA Letter of non-objection for dry-aseptics

In December 2010, Krones has received a letter of non-objection from the FDA for a rotary dry-aseptic PET-bottle filling system featuring H₂O₂ as the sterilising agent.

The system works in the low output category and has been installed in a Nestlé research department in the U.S.

In a complete dry process, bottle and closure sterilisation as well as sterilisation of seal and isolator (after caustic CIP) are based on the use of evaporated H₂O₂ instead of peracetic acid which had formerly been used.

The machine has currently been validated for 48 hours of continuous operation. The cleaning and sterilisation process after this period takes a mere 3.5 hours.
