Abstract
Icemakers are characterized by a plurality of vertical evaporator tubes arranged in parallel and in a circle within the interior of a cylindrical ice making section. During an ice making cycle, water is supplied to the exterior surfaces of the evaporator tubes and refrigerant is supplied to the interiors of the tubes, to cause tubes of ice to freeze on the evaporator tubes. At the end of the ice making cycle and during a harvest cycle, the evaporator tubes are heated to free the ice tubes from their bond to the evaporator tubes, and a driver is actuated to move the ice tubes slidably along and off of the evaporator tubes and to fracture the leading ends of the ice tubes into smaller pieces of ice as they leave the evaporator tubes. In one embodiment, the driver comprises a piston for pushing the ice tubes off of the evaporator tubes. In another embodiment, a helical driver moves the ice tubes off of the evaporator tubes.
