Decontamination of infant powder milk cans

Claranor launches a dry, chemical free, can sterilisation solution

Claranor has designed the first pulsed light sterilisation equipment dedicated to infant formula milk powder cans. The unit will be on display at the Anuga Foodtec in March.

Claranor already offers reliable and sustainable pack sterilisation solutions for ultra-clean and ESL lines for dairy products including the following: caps, cups and foils.

Infant milk powder is a brand-new market for Claranor. The market of infant formula milks has a very demanding quality system and it is expected that the level of regulation will only increase to meet international specifications.

To comply with producers' expectations, Claranor has designed a dry cooling system and it has performed several microbiological trials to demonstrate the efficiency on a new range of micro-organisms: Cronobacter sakazakii, Bacillus cereus, Candida albicans.

To achieve dry sterilisation, cooling of the pulsed light sterilisation unit will be carried out using air instead of a closed water cooling system, which is currently used.

The microbiological tests are performed by Claranor's internal laboratory in Avignon and repeated by an external laboratory, the Fraunhofer Institute, to insure the neutrality of the results. They will be presented during the trade-fair.

The Claranor prototype presented during the show has been designed for the most common format on the infant milk powder market: a can of 900 g with a diameter of 127 mm on a single-stranded conveyor, with a speed-line up to 300 strokes/minute.

The can steriliser will be running on the booth giving the chance for visitors to see the equipment in operation. The unit meets the standard of food safety: hygienic design (stainless steel 304) and cleanability.

On top of dry decontamination, the Claranor solution offers several advantages compared to existing technologies

  • high level of efficiency
  • no heating around the treatment zone
  • compact equipment, easy to integrate on new or existing line (<1.5 m)
  • instant treatment (no pre-heating time)
  • lower running costs
  • sustainability (no hazardous waste management)

Claranor offers a full range of packaging sterilisation solutions dedicated to ESL for dairy and food markets.
