ABSTRACT:
Ice-making apparatus having an evaporator including a helical tubing section, means for supplying water to the exterior surface thereof and means for supplying refrigerant to the evaporator to cause freezing of a helix of ice on the exterior surface thereof. An elongated driver is located axially within the helical tubing, and hot gas from the compressor frees the ice helix from its bond to helical tubing following discontinuation of supply of refrigerant thereto. The driver is rotated to slide the ice helix along the tubing and fracture the leading end of the helix into smaller ice pieces at a discharge point, preferably at the top of the unit.
A star-wheel driver may be located coaxially within the helical tubing and have four radially extending fins for engaging grooves in the interior surface of the ice helix. The four fins are warmed so as to obviate formation of a strong bond between them and the ice helix. Water fills a tubular surrounding enclosure to sufficient depth to immerse a substantial portion of helical tubing, and air is supplied to a lower location therewithin during freezing to agitate the water and promote the formation of a helix of clear ice.
