An ice machine includes an evaporator with a plurality of individual ice-forming cells. Each ice-forming cell is open at a lower end. A water distributor is coupled to the evaporator and configured to deliver water to the upper end of each ice-forming cell. A refrigeration system in the ice machine is configured to cool each of the plurality of ice-forming cells, such that individual ice cubes are formed in each ice-forming cell. A water recirculation system includes a water collection unit positioned between the evaporator and a water sump. The water collection unit collects water flowing from the ice-forming cells in first and second chambers. A water detection probe is positioned in the second chamber. A harvest cycle is initiated when the water level in the second chamber falls below a specified level. A method of operating the ice machine is also provided.

Low-volume ice making machine

An ice making machine has a water system, including a pump, an ice-forming mold and interconnecting lines therefore; a refrigeration system, including a compressor, a condenser, an expansion device, an evaporator in thermal contact with the ice-forming mold, and a receiver. The receiver has an inlet connected to the condenser, a liquid outlet connected to the expansion device and a vapor outlet connected by a valved passageway to the evaporator. In a preferred embodiment, two interconnected receivers are used. A cabinet housing the evaporator is preferably less than 18 inches deep. The pump is preferably mounted so that the pump motor is located outside of the water compartment, but can still be removed from the front of the machine.

Compact ice making machine with cool vapor defrost

A method of making and harvesting ice cubes includes freezing water in an ice-forming mold having a back surface, an open front face and dividers mounted on the back surface forming pockets for the formation of individual ice cubes, the water also forming ice bridges between the ice formed in the pockets, thus forming a slab of ice cubes; heating the ice-forming mold to release the ice cubes from their individual pockets; and using pressurized fluid to push the frozen slab of ice cubes out of the ice-forming mold. An ice making machine for practicing the present invention preferably includes an air compressor to supply compressed air as the pressurized fluid. The compressed air is directed preferably through a plurality of holes in the back of the ice-forming mold. Weep holes in the dividers allow this pressurized air to migrate from these holes to the areas behind each of the pockets in the ice-forming mold, thus applying a uniform pressure over a large surface area to assist the slab of ice in releasing from the ice-forming mold. The assisted harvest greatly increases the energy efficiency of the ice machine.

Ice machine with assisted harvest

An ice making machine has a water system, including a pump, an ice-forming mold and interconnecting lines therefore; a refrigeration system, including a compressor, a condenser, an expansion device, an evaporator in thermal contact with the ice-forming mold, and a receiver. The receiver has an inlet connected to the condenser, a liquid outlet connected to the expansion device and a vapor outlet connected by a valved passageway to the evaporator.
