Apparatus is provided for automatically dispensing CO2 snow on articles moved by a conveyer underneath a snow storage container-dispenser outlet opening. The dispensing is controlled by a motor driven segmented drum with brush-like elastic blades closing the dispenser outlet opening actuated when an article is moved into place thereunder. The snow is generated from liquid CO2 flowing through cooling coils in the snow and dispensed through a nozzle in the upper portion of the container in response to capacity sensing means such as a photocell level detector to thereby keep the container snow level constant. |
