With the PET-Asept D Compact for dry-aseptics, bottlers now have an option for handling even relatively small batches in aseptic mode while retaining viable cost-efficiency.
The PET-Asept D Compact is based on a line acceptance-tested by the American Food and Drug Administration. It no longer needs any sterile-water UHT system in order to operate: the containers and the isolator are sterilised with gaseous hydrogen peroxide. The machine itself is cleaned using caustic and acid, which means that peracetic acid and foam cleaning products are no longer required on the system.
How it works
Containers are passed by a gripper conveyor system first through a pre-warming zone, then sterilised by means of gaseous H2O2 before entering the blow-out section of the steriliser. After this, the containers are filled and capped. The height-adjustable conveyor is already isolated from the sterile zone, which means that minimised change-over time are achieved without any handling parts needing to be replaced.
The PET-Asept D Compact filler from Krones has an output range covering 6,000 to 12,000 containers an hour. It can be installed as a stand-alone line component or monobloc-synchronised with a stretch blow-moulding machine.
A first reference line featuring the new PET-Asept D Compact was implemented by a German bottler earlier this year.
