A heated issue: product treatment

Delicate products like juice drinks are thermally treated before filling – whether in glass or in PET bottles. This has a beneficial effect on the taste of the product which is one crucial factor for its sales success. But a much more important feature of hot filling is product safety and quality, because yeasts and moulds are the most frequent cause of spoilage. Pasteurisation at temperatures exceeding 100 °C can kill pathogenic germs and deactivate enzymes. Temperatures for sterilisation are less than 100 °C. All microorganisms – except for the heat-resistant spores – are killed off.
Krones offers suitable systems for this type of product treatment:

The product treatment step is individually designed: the heat retention time and the heating strategy are adapted to the product concerned in order to achieve optimal process reliability and maximised product quality. The flexibility of the systems´ performance capabilities provides the bottler with scope for many new product developments.
