Abstract
A method and apparatus for dispensing a soft food mix, such as soft ice cream, milk shakes, yogurt or the like whereby mix from a pressurized container passes through a heat exchanger and particularly passes in a line disposed within a hollow coil immediately adjacent to a second line which carries either a heating or cooling fluid to prevent formation of an ice plug and maintain the proper consistency. Thermisters disposed on the coil sense the temperature of the mix and provide electrical control signals to automatically control supply of the heating and cooling fluids.
