ABSTRACT:
A repetitive ice block or cube maker in which chilled water flows over a vertical evaporator to form ice blocks within ice freezing pockets of designated shape. The ice blocks are positively released by concurrently heating the evaporator while inducing a designated vibration in the evaporator. The vibration may be of sonic or ultrasonic frequency. A breather vacuum breaker vent may be provided in the bottom of each ice pocket. Each ice block is released with a minimum of heat being developed while heating the evaporator.
