Cup sterilization with H2O2 and hot sterile air

Sterile air and H2O2 consumption, as well as all necessary valves and pipes are placed in a separate sterile module next to the machine.
The running cups are sterilized with a mix of sterile air and H2O2 and are dried on two further stations.

Cup sterilization with UVC-irradiation above the cups

consisting of:

  • UV-high-pressure irradiators in most advanced design
  • Irradiator housing with cooling fan
  • Control unit for regulation of irradiation intensity.

Cup sterilization with "Pulsed Light"

A high-intensive flashlight with a flash interval of 0,1 sec. sterilizes the inner cup surface effectively.

Sterilization station, consisting of:

  • Electrical control cabinet with loading and unloading electrics
  • Optical cabinet with gas unloading reflectors
  • Passive safety system (covers with safety switches)
