A refrigerant system includes a compressor connected to a first valve forming a harvest line, a condenser connected to the compressor by a first segment of conduit and an expansion device by a second segment of conduit with the condenser and the second segment of conduit forming a liquid line. A third segment of conduit is connected to the liquid line and the harvest line with the third segment of conduit having a second valve. The second valve allows flow of refrigerant from the liquid line to the harvest line through the third segment of conduit in an open position and the second valve blocking flow of the refrigerant from the liquid line to the harvest line through the third segment of conduit in a closed position.

Refrigerant system with liquid line to harvest line bypass

An ice making system includes a flavored liquid, an ice machine and a refrigerated storage bin. The ice making system continuously produces flavored ice pieces for storage in an ice storage bin. A refrigeration system cools the ice storage bin.

Method and system for the continuous or semi-continuous production of flavored ice

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.

An ice maker in which a non-metallic shroud surrounds the metal evaporator plate and has a continuous bulbous edge that engulfs the edges of the plate. The shroud further includes a roof disposed above the plate and slopes toward the front of the plate. The water distributor of the ice maker is mounted on the roof of the shroud.

Domestic clear ice maker

An ice maker in which a non-metallic shroud surronds the metal evaporator plate and has a continuous bulbous edge that engulfs the edges of the plate. The shroud further includes a roof disposed above the plate and slopes toward the front of the plate. The water distributor of the ice maker is mounted on the roof of the shroud.

An ice making machine comprises a refrigerant system having a compressor, a condenser, an expansion device, an evaporator and interconnecting refrigerant lines; a water system having a fresh water inlet, a water circulation mechanism, an ice-forming device in thermal contact with the evaporator and interconnecting water lines; and a control system comprising a temperature sensing device in thermal contact with the outlet of the condenser, and a microprocessor programmed to use input from the temperature sensing device either i) at a predetermined time after initiation of a freeze cycle to determine the desired duration of the freeze cycle or ii) at a predetermined time prior to the end of the freeze cycle to determine the desired duration of the harvest cycle, or iii) both i) and ii), to control the refrigeration and water systems to operate in a freeze cycle and/or the harvest cycle until the end of the desired duration(s).
