BOTTLING / FILLING PET planet Insider Vol. 21 No. 03/20 www.petpla.net 31 Effective sterilisation When further developing its linear aseptic filler KHS focused on increased efficiency. The filling machine for sensitive products is available in both a standard aseptic and ESL version. In the KHS process sterilisation takes place in several stages. First, the machine disinfects the neck and bottle interior. Here, the inside of the con- tainer is sprayed twice with a hydrogen peroxide aerosol (H 2 O 2 ) at a speed of up to 80km/h. “This ensures that every part of the bottle is sprayed and sterilised; we even achieve this with individual designs and critical shapes,” Redeker states. Secondly, two aero- sol reaction cycles are initiated. The process ends with a four-stage drying process which uses sterile hot air. Gentle filling for product protection In order to ensure the quality of the products, it is essential that the aseptic zone is absolutely clean. KHS said they are doing so by gentle non- contact filling, among other things, performed in two stages. This prevents any excessive beverage foaming. After filling the bottle is conveyed to the capping unit. Here, the closure is sterilised in the same manner as the bottle in the filling section. This entails two-step disinfection with H 2 O 2 and two drying stages with hot sterile air. “In the capper unit we’ve also made sure that all parts in the aseptic zone have a flat surface. By doing so we can prevent any air turbulence, making cleaning and disinfection easier,” Redeker com- ments. The bottle is then dated for full documentation of all information. “Our customers can always see which prod- uct was filled when on which valve,” explains Redeker. One-block system With its new dry aseptic block KHS reacts to the current dairy demand for flexible, resource-saving filling of sensitive products. The system boosts line availability and considerably reduces energy consumption. Opera- tors have greater flexibility thanks to the short changeover times: format changes are facilitated by the well- coordinated interfaces. The modular design enables customers to expand their linear aseptic filler block in order to meet current market demands at all times, KHS stated. www.khs.com High output: The new linear InnoPET BloFill ABF aseptic block is designed to fill milk, mixed milk beverages, juice, smoothies and iced tea into PET bottles holding between 250ml and 2 l. 40 Bar Oil-Free Piston Compressors For PET Applications. www.hertz-kompressoren.com Building the future in every moment of your business
