Abstract
An ice display device includes a chill tube and a piston that slides within the chill tube providing a fluidtight seal against the interior. The tube is filled with water and cooled to form an ice column. A shutter may selectively close the upper end of the chill tube with a fluidtight seal while the ice column is formed. The tube is warmed and the piston is lifted to an upper end of the tube to display the ice column. A plurality of water nozzles may selectively discharge streams of high pressure water inwardly to sculpt the ice column. An armature may extend upwardly from the piston to support and cool an interior of the ice column. The tube and armature may be cooled and warmed by a thermal transfer fluid. A device may be provided to induce turbulence in the thermal transfer fluid.
