Abstract
Apparatus to prepare an airstream laden with particles of solid dry ice. A rotor has passages which sequentially pass a source of particles and a source of air under pressure to prepare the airstream and send it to a nozzle. The rotor is held between pads whose force against the rotor is a function of air supply pressure. The speed of the rotor and of the particle feed are controllable, and the air feed persists after particle feed has stopped for a period of time sufficient to clear particles from the rotor.
