RAPID FLUID COOLING AND HEATING DEVICE AND METHOD

摘要

A method and device for rapidly changing at least one of the temperature and the state of a liquid in a container (10) is provided. The container (10) is rapidly rotated about its longitudinal axis. A source of a thin film of a medium having a different temperature than the liquid in the container (10) is provided to thermally affect the container (10) while rotating the container (10). The container (10) is positioned at an angle to the horizontal of less than 45~, and the position of the container (10) with respect to the thin fi lm source is controlled by angling the axis of the container (10) skewed from t he axis of the rotating mechanism. The device can be used to cool liquids such as beverages, warm liquids such as infant formula, and/or make ice cream.
