BOTTLING / FILLING PET planet Insider Vol. 19 No. 10/18 www.petpla.net 23 Flexibility in the pasteurisation process Microbiological safety With the Innopas SX KHS GmbH provides a tunnel pasteuriser in a modular design. The systems supplier from Dortmund, Germany has optimised spare part management for this flexible machine. The beverage market is facing increasing levels of dynamic com- petition, with new flavours in new packaging formats hitting supermar- ket shelves at ever shorter intervals. Flexibility is thus becoming more of an issue when it comes to filling. The necessary pasteurisation of filled and sealed beverage containers for longer shelf lives is a decisive factor. The completely modular KHS Innopas SX tunnel pasteuriser is intended to sat- isfy these demands for PET and glass bottles and cans. Dynamic adaptation to line behaviour The basic functions of the Innopas SX are initially identical to the tried- and-tested tunnel pasteuriser sys- tems already provided by KHS. The dynamic pasteurisation unit or PU control system reacts variably to changes in conditions. If, for example, a fault occurs during the pasteurisa- tion process, the process tempera- tures are kept under control in the hot zones of the tunnel pasteuriser to ensure both product safety and flavour stability. New features on the KHS Innopas SX include extended functions in the dynamic PU control system which result in greater flex- ibility and yield savings in energy and media. Much of this is attributable to the optional speed regulation func- tion. The individual zone temperatures are automatically raised or lowered depending on the conveyor speed. “This allows the pasteuriser to dynam- ically adjust to match the line behav- iour within a range of 50 to 105% of the nominal capacity for most pro- cesses without making any drastic changes to the pasteurisation units and maximum product temperature,” states Knut Soltau, product manager for Bottle Washers and Pasteurisers at KHS. This prevents the correspond- ing consumption of media and at the same time has a positive impact on the behaviour of the entire line. With a new program for PU control the customer can independently adapt the pasteurisation unit setpoint for a specific container type. Here, the full functionality of the PU control unit is maintained. “In this way subsequent product changes or new products can be easily made or introduced at any time,” says Soltau. “Bottlers can thus react quickly to changes on the market and product trends.” Improved design KHS has also made several improvements to the design of its Innopas SX, with emphasis on easy operation. The tunnel pasteuriser is clearly structured; optimum access simplifies the maintenance and clean- ing of the system. For this reason, parts of the process engineering, such as the heat exchangers and media supply, have been relocated on the machine as modules in order to further improve servicing and machine safety. Spare part management for the KHS Innopas SX has also been opti- mised. The number of components the customer is required to keep in stock has been reduced while the delivery times for spare and wear parts have been shortened, meaning that func- tions can also be simply retrofitted as an option. www.khs.com The Innopas SX tunnel pasteuriser product development caps & closures design high cavitation moulds multi-component moulds closure production systems after sales service competent – professional – inspiring Dr.-Walter-Zumtobel-Strasse 9 | 6850 Dornbirn | Austria | www.z-moulds.com FAKUMA 2018 October 16th-20th meet us at booth A7-7502 Mould at FAKUMA 26mm 3-start water, 72-cavity @ENGEL, booth A5-5204
