Definitions

  • the present invention relates to an apparatus and method for cleaning articles by dry snow.
  • Dry ice is carbon dioxide converted to the solid state and cooled to at least -78.5 ° C. Dry ice passes under atmospheric pressure directly from the solid state in the gaseous, whereby no molten liquid is formed. This can be particularly easy Way, namely with normal compressed air, both the bombardment with dry ice and the suction and removal of dirt particles done.
  • Dry ice is present during production in the form of snow.
  • the cleaning effect of CO 2 snow is limited. To remove more stubborn soils, it is compressed into granules or pellets or the like by pressing them through dies.
