Abstract
Abstract A CONSTANT VOLUME OF ICE CREAM OR SIMILAR MATERIAL IS POSITIONED IN EACH OF A SERIES OF CONTAINERS. THE FILLED CONTAINERS ARE WEIGHED, AND A SIGNAL IS ESTABLISHED WHICH IS REPRESENTATIVE OF THE WEIGHT OF EACH CONTAINER. IN RESPONSE TO THIS SIGNAL THE DENSITY OF THE PRODUCT IS ADJUSTED SO THAT A PREDETERMINED VOLUME-WEIGHT RELATIONSHIP IS MAINTAINED. THIS CAN BE ACCOMPLISHED BY ADJUSTING AIR INTRODUCTION TO THE ICE CREAM FREEZER, FOR EXAMPLE.
