Abstract

The Cold carbon dioxide jet has a liquid carbon dioxide line with valve to form crystals and an annular compressed air input. It has (in direction of flow) an expansion jet (3) to create dry ice particles, and a capillary tube with a conical end to create snow crystals. The compressed air channel and the capillary tube are concentric. The jet tube (4) and the outlet (8) are rectangular. A spiral flow of carbon dioxide snow is created.
