ABSTRACT:
A method and apparatus for rapidly chilling liquid or slurried food products through a two-stage sequence of jacket cooling followed by vacuum chilling. Slurry and liquid food products heated in a batch are chilled by first employing a chilled liquid flowing through a double walled jacket (22) surrounding the vessel chamber (17). When the food product reaches a temperature at which jacket cooling becomes inefficient, this is followed by pulling a vacuum in the space above the product to vacuum cool the product to the desired chilled temperature.
