<p>The ice machine includes an elongated, flexible member (64) formed as an endless loop which is rotated through a freezing tube (26) by means of a harvesting pulley (60). The freezing tube (26) includes an evaporator (96) therearound in order to freeze water in the tube (26) and around the flexible member portion located therein. After an ice column (136) is formed, hot refrigerant gas passes through the evaporator (96) to loosen the ice column (136) from the tube interior (38) whereupon the pulley (60) rotates to withdraw the flexible member portion from the freezing tube (26) and the ice column (136) attached thereto upwardly therefrom. The ice breaking element (66) adjacent the pulley (60) engages the ice column (136) and fractures it into chips (138) as the flexible portion passes over the pulley (60).</p> |
