ABSTRACT:
A machine for manufacturing ice including a plurality of elongated vertical tubes of uniform internal cross-sectional dimensions, a cylindrical shell for each tube of length less than the tube and surrounding a substantial portion of the length of the tube, the internal nominal diameter of the shell being greater than the maximum external cross-section dimensions of the tube, the shell having a spiral groove formed in the cylindrical wall thereof, the depth of the groove being such that the interior surface of the shell at the groove contacts at least part of the exterior surface of the tube thereby forming a flow path in the annular area between the exterior of the tube and the interior of the shell which is, at least in part, spiraled. Refrigerant gas is expanded in the tube-shell annular areas to chill the tubes. Water is introduced into the upper end of the tubes to flow downwardly through them and form in each tube a rod of ice. The tubes are then heated, such as by introducing hot gas into the annular tube-shell area to release the rods of ice which falls downwardly out the lower end of the tubes, the annular refrigerant flow path providing improved effectiveness and efficiency in chilling the tube for the formation of ice. Pivotally actuated cutter sever the rods of ice into short lengths. A diverter arrangements directs water flowing out of the tubes as ice is being formed into a reservoir and shifts to direct the produced ice out of the machine.
