Packaging machinery specialist Multivac claims it is now possible to integrate high-pressure treatment into automated packaging lines and also to apply high pressure processing (HPP) treatment to modified atmosphere packaging (MAP).
HPP is designed to deactivate microorganisms, such as salmonella or listeria, without loss of nutritional value or flavour.
Thanks to Uhde High Pressure Technologies, pressure in the sterilising autoclave is regulated so as to put the packaging material under less stress, allowing it to retain its functionality after the high pressure treatment.
Multivac further says it has the means to integrate modular HPP systems in automated packaging lines. The development is a result of German machine builder KBH’s ‘groundbreaking’ approach for the transport containers. It entails specific packaging loading patterns being defined, which specify the nature and manner of the packaging placed into the loading baskets by the automated handling modules, to handle as many packs as possible per cycle. The loading baskets have ‘special’ inserts to minimise the unfilled volume of round containers. Maximum machine throughput guarantees high efficiency, explains Multivac. In addition to single chamber systems, with volumes of 55, 160 and 350 litres, there is a tandem system with a capacity of 700 litres (2 x 350 litres).
