Abstract
Abstract A regulated flow of water is refrigerated, and a source of concentrated orange juice at atmospheric pressure is also refrigerated and is metered and combined with the water under pressure in a refrigerated blending and storage device along with nitrous oxide gas, and the resulting mixture is transferred to a separate freezing chamber where water is frozen from the mixture as pure ice. The mixture is dispensed from the freezing chamber to atmospheric pressure so that the nitrous oxide gas breaks out of the semifrozen product to render it fluffy.
