Abstract: The present invention provides an apparatus and method for producing substantially clear ice in a variety of desired shapes. An insulated ice mold form containing one or more mold cells is suspended over a liquid water reservoir contained in an insulated container. Each ice mold cell is exposed to freezing air resulting in the formation of ice in each mold cell with ice formation progressing from the top to the bottom of each ice mold cell. A liquid water reservoir below each ice mold cell serves as an impurity sink into which impurities and gases are driven as ice crystals form in each ice mold cell and as a heat sink to substantially arrest ice shape growth beyond the bottom of each ice mold cell at or near the ice-reservoir water interface.

Abstract: A clear ice making system and method utilizes an ice forming tray pivotally connected to opposing side walls of an icemaker housing. Ice forming fingers of a dedicated evaporator extend into fluid within the ice forming tray, and are cooled by communication with the refrigerant circulating system of the refrigerator. A motor oscillates the ice forming tray about a longitudinal axis at a frequency of about 0.4-0.6 hertz as fluid channels freezes on the ice forming fingers over time, forming clear ice pieces. During an ice dispensing event, the motor pivots the ice making tray about the longitudinal axis such that fluid remaining within the ice making tray drains into a fluid reservoir below. The ice forming fingers are then heated to release the clear ice pieces for transfer from the fresh food compartment to the freezer compartment of the refrigerator.

Abstract: An apparatus for decontaminating water in an ice machine or a beverage-dispensing machine comprising an ultraviolet radiation source, an ozone source and a controller. As potable water enters the apparatus via a conduit, the potable water is decontaminated by an ultraviolet (UV) light source, which irradiates the potable water, and by an ozone generation system that provides ozone to be injected into the potable water to oxidize contaminants. Because water is often circulated within ice machines, the circulating water conduits and reservoir are also treated with ozone and UV radiation. The present invention also provides a controller for optimizing the decontamination process by providing UV light and ozone production only when required for decontamination. Typically, ozone generation and UV radiation are required whenever makeup potable water is brought into the apparatus or when the refrigeration compressor is running.

Abstract: Apparatus and method are disclosed for production of ice and maintenance of an ice conveyance free of microbial contamination. Ozone is incorporated into water from which the ice is made, so that significant ozone content is present in the ice. This ice may be recovered for human consumption. The ice manufactured in the ice maker is conveyed through a conveyance system to one or more locations remote from the ice maker, where the ice is to be used. Ozone gas is evolved as the ice melts, sublimes or is abraded. The evolved ozone evolved penetrates into all areas of the system and kills substantially all microbial materials which are within the system. Cleanliness is thereafter maintained since passage of more ice and water though the system causes the evolution of additional ozone, which in turn kills any microbial contamination which may subsequently get into the system.

The system comprises a device for treating at least one of the incoming stream and the recirculating supply in the transport conduit before the water from either flows over the evaporator plate.

Abstract: A water filter assembly mounted to an inner surface of a refrigerator and accessible from within a refrigeration compartment of the refrigerator. The filter assembly includes a first housing part, a second housing part, and a replaceable filter cartridge. The first and second housing parts cooperate to define a fluid-tight chamber for receipt of the filter cartridge.

The second housing part surrounds a portion of the first housing part and provides a volume sufficient to hold the filter cartridge and any water within the chamber when the second housing part is released from the first housing part to replace the filter cartridge, and thereby prevents or minimizes spillage of water from the filter assembly during filter cartridge replacement.

Abstract: The invention relates to a process and an apparatus for the granulation of granulatable and/or pelletizable substances in which the substance to be granulated is introduced in the form of a closed jet into a rapidly flowing refrigerant--preferably liquid nitrogen.

Abstract: An apparatus for growing free-floating, buoyant crystals to a predetermined size. Crystals having a positive buoyancy such as water crystals (ice) grow due to immersion in a stream of supercooled feed water that flows downward in a tapered incubation duct with a velocity that decreases as the cross-sectional area of the duct increases with increased depth. As the crystals grow, their terminal buoyant velocity increases until it exceeds the peak stream velocity. At this time the crystals float upward and out of the apparatus. A plurality of interconnected incubation ducts may be stacked vertically one above the other. The apparatus may be combined with apparatus to grow free-floating crystals having a negative buoyancy from a supersaturated salt solution that is discharged from the bottom of the apparatus for growing crystals having a positive buoyancy.

Abstract: In a method of freezing a liquid such as cream, a continuous, pulsating stream of liquid is dispensed from nozzles onto a stream of liquified gas flowing along downwardly inclined channels provided by a trough. The liquid forms itself into discrete spheroidal bodies, a substantial number of which have a larger cross-sectional area than that defined by the outlet of each nozzle from which they are dispensed. The bodies are carried by the liquified gas along the channels and at least their peripheries are frozen by the time the bodies reach the downstream end of the channels. Freezing may be completed by gas cooling. The bodies are then separated from the liquified gas.
