Abstract
A method of producing ice while substantially reducing encapsulation of refrigerant in the ice by feeding a liquefied refrigerant in the form of a jet of very fine droplets to an aqueous body whereby the liquefied refrigerant is very rapidly vaporized and ice is produced, by transfer of heat from the adjacent water to the refrigerant, without encapsulating any significant amount of refrigerant in the ice. The refrigerant within the feeding device is desirably at a temperature above the freezing point of the aqueous body so as to prevent ice from forming on refrigerant feeding devices and blocking outlet orifices therein. Apparatus for producing ice in an aqueous body comprising a closed vessel for holding an aqueous body; a device for feeding a liquefied refrigerant in the form of very fine droplets to an aqueous body in the vessel; a conduit for feeding an aqueous liquid into the vessel; and a conduit for withdrawing an aqueous ice slurry and refrigerant vapor from the vessel.
