Abstract
A method for the production of ice from water filled stalls and comprised of applying heat absorption thereto until an iced condition is reached, followed by the simultaneous application of heat thereto to thaw the stall-to-ice interfaces and of refill water thereto to eject the ice by means of floatation; to be embodied, for example, in apparatus to perform this method comprised of one or a series of stalls embraced by the evaporator of a refrigeration system having a hot gas bypass that is intermittently discharged through the evaporator simultaneously with refill water applied to the stall or stalls to eject the ice, a temperature sensor and refrigerant control alternately reacting to effect the iced and thaw conditions of the stall, thereby automatically cycling the apparatus for continued operation.
