Krones develops new aseptic filler for low output companies

Krones AG, a plastics processing technology provider based in Germany, has developed a

compact sized aseptic filler, PET-Asept D Compact, for mid tier companies with low output range, according to the company’s press release on June 27.

The PET-Asept D Compact is based on a line acceptance-tested by the US FDA (Food and Drug Administration). It no longer needs any sterile-water UHT system in order to operate: the containers and the isolator are sterilized 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. Its small footprint on a minimized floor area is comparable with linear machines, says Krones.

In the core section, the machine’s design concept needs an area of merely 6x2m. In there, the containers are passed by a gripper conveyor system first through a pre-warming zone, then sterilized by means of gaseous H2O2 before entering the blow-out section of the sterilizer. After this, the containers are filled and capped. The height-adjustable conveyor is already isolated from the sterile zone, which means that minimized change-over time is achieved without any handling parts needing to be replaced. This machine 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-synchronized with a stretch blow-molding machine.

Krones states that a first reference line featuring the new PET-Asept D Compact was delivered to a German bottler early this year.
