KHS Pacific ’s ACF compact system for dry sterilisation is a completely enclosed system for the cold aseptic filling of still and sensitive products in PET and HDPE containers (bottles and caps). The product range covers still mineral waters, fruit juices and fruit spritzers, as well as iced teas, wellness drinks, milk and mixed milk drinks. The system requires an installation area of 15m2.
The system has high-efficiency particulate air (HEPA) filters in the roof, as well as a neck ring isolator. It complies with Class 100 clean room quality - this is less than a quarter of a litre of clean room volume per bottle. In order to maintain this quality, a total of four tubes are in permanent use, ensuring the continuous supply of sterile air. The result is a laminar flow which ensures that no germs of any kind can remain within the clean room area.
The sterilisation process begins with the addition of warm sterile air. The H2O2 is activated and decomposes into oxygen and water during the heating process, then dries without leaving residue. The plastic bottles are then fed into the filler area where they are filled under Class 100 clean room quality conditions.
The Innofill NV filling system has a servomotor in place of a gearbox. It provides maximum microbiological and hygienic safety due to the non-contact filling process using an open jet filling valve. Volumetric filling using an electromagnetic induction flowmeter ensures precise filling quantities from start to finish. The system can easily and conveniently be changed over for different bottle sizes and shapes at the push of a button.
The dry sterilisation process is rounded off by the Innofill SV-ACF ACF-compliant capper, offering separation of the capping movement into the rotary movement of the cap and the vertical movement of the bottle. Major cleaning of the system should be performed every 48 to 72 hours, which also includes the complete CIP and SIP cycle. Rinsing with sterile water under pressure is normally sufficient for product changeover.
