Aseptic filling of sensitive beverages in PET
July 7, 2009
In response to changes in consumer preferences and the increasingly stricter regulations in food, aseptic filling opportunity to reformulate a more naturally sensitive beverages so far have been packaged with preservatives.
Combi Predis FMa is a simple and innovative system of Sidel for blowing of bottles and filling of sensitive products in aseptic conditions. The key feature that distinguishes this system is the ' dry technology for preforms ', which substitutes a dry sterilization of bottle rinsing of her preform at the entrance of the oven, which uses steam of hydrogen peroxide (H2O2). Combi Predis FMa combines the Predis solution with the latest technology for aseptic filling of Sidel, Sensofill FMa, in a team for blowing, filling and covered consisting of a single machine.
Maximum hygiene and energy saving
The solution of the dry sterilization of preforms has numerous advantages. According to the company, Predis offers "maximum hygiene sensitive beverages, an unparalleled profitability and numerous advantages to the product and the environment". While a traditional aseptic bottling line uses daily 250 cubic metres of water and 200 liters of chemical agents to decontaminate the bottles, the dry solution Predis clears preforms them using hydrogen peroxide vapor, so it does not need waterit consumes a minimum of chemical agents and does not generate waste liquids. Other advantages are energy savings, reduction of the total space needed for the machines and the possibilities of reducing the weight of the bottle: with high temperature sterilization of preforms them instead of bottles, eliminates the thermal stress on empty bottles.
The PET is the dominant material in the packaging of juices, Nectars and teas, and begins to be seen increasingly as an alternative to milk. Treatment of little acidic drinks at room temperature, such as milk and other dairy products, they are very delicate and require an even more careful work, is a real challenge. In collaboration with a milk producer, Sidel is now confronted with the challenge of entering in the latter field of application: the aseptic filling of milk UHT by Combi Predis FMa.
