A batch ice maker can execute a pulsed fill routine in which a control system pulses water from a water supply into the sump until the sump reaches a predefined freeze routine starting level. Pulsing may begin after continuously filling the sump to a fill-approach level. A batch ice maker can execute a differential freeze routine in which the control system circulates water from a sump to an ice formation device until water level decreases by a predefined differential amount from a high control water level based on the water level in the sump at a point in time after the sump was filled to a freeze routine starting level. The high control water level can be set based on water level in the sump when sump water temperature reaches a predefined pre-chill temperature. The predefined pre-chill temperature can be associated with a switchover from sensible cooling to latent cooling.

An ice making assembly for a refrigerator appliance includes a resilient mold defining a mold cavity and a heat exchanger in thermal communication with the resilient mold to freeze water and form one or more ice cubes therein. The ice making assembly also includes a lifter mechanism positioned below the resilient mold for selectively deforming the mold and raising the ice cubes formed therein. A resilient seal is sealingly engaged with the lifter mechanism and the heat exchanger, whereby an air-tight seal is formed between the lifter mechanism and the resilient seal and between the heat exchanger and the resilient seal.

A system for manufacturing clear ice products is provided. The system includes a freezing module, a demolding module, and a converting station. The freezing module includes a frame comprising a plurality of levels, a plate freezer provided at each level, and at least one mold provided for placement on each plate freezer and suitable for receiving water. A control frame is provided associated with each plate freezer and is movable from an elevated position to fill position. In the fill position, the control frame is at least partially disposed within the mold. One or more circulation pumps are associated with each control frame for circulating water in the mold to release air bubbles as the water freezes. The demolding module removes the mold from the freezing module and removes formed ice from the mold. The converting station converts the formed ice into a clear ice product.
