Abstract
A continuous stream of compressed air is introduced to a elongated chamber surrounded by a distribution jacket for introducing water at substantially the same pressure via a multitude of inward directed tubular members into the stream of axially moving, decompressing air. The stream of partially decompressed air atomizes the introduced water into tiny droplets which are mixed with the air, and are accelerated through a converging-diverging exit nozzle so as to be projected through a distance, along which the swiftly moving droplets cool from their initial to nucleating temperature, and ultimately freeze into crystalline particles of ice.
