Sterilization

Our recommendations


Ultraviolet (UV) and Gas ozonation

Potential benefits

  • +Low specific consumption
  • +Easily adapted to work with existing equipment
  • +Short sterilization times
  • +Suitable for dry processing
  • +Chlorine not needed for sterilization

Electron beam

Potential benefits

  • +Very few flaws and reduced wear over the long term as a result of low exposure
  • +Quick, effective sterilization of uniformly packaged low-density products

An electron beam is generated using two instruments: an electron gun and a magnetic or optical guide to direct the beam. The gun consists of an anode and a cathode operating in a vacuum. When the gun is turned on, the cathode directs a flow of electrons toward the anode, creating a beam that can be focused on the part to be treated.

Ultraviolet treatment is used as an alternative to the heat process pasteurization of juices. UV radiation kills microorganisms by penetrating their cell membranes.
