Abstract
An apparatus for producing dry ice is provided. The apparatus generally includes an expandable shell assembly, an expansion control assembly for controlling expansion of the expandable shell assembly, and a delivery system for delivering liquid carbon dioxide from a supply of liquid carbon dioxide to the dry ice chamber. The expandable shell assembly is made of multiple separable shell portions and an inner surface of at least one of the shell portions forms a wall of the dry ice chamber. The expandable shell assembly is structured to automatically relieve pressure within the dry ice chamber when the dry ice chamber has been sufficiently filled with a mass of dry ice.
