Abstract
A machine for making ice cream and the like, having a receptacle for receiving liquid ingredients to be used for making the ice cream. A mixing chamber is provided which has an egress from which the ice cream exits. A cooling chamber surrounds the mixing chamber. A rotor centrally mounted in the mixing chamber atomizes and mixes the liquid ingredients and moves it through the mixing chamber to its egress. The rotor has a central post and outwardly projecting blades. A conduit feeds the liquid ingredients from the receptacle to the central post of the rotor. An outlet port on the central post is provided, through which the liquid ingredients are ejected outwardly from the central post for action by the blade means. A pull down screw arrangement helps pull down the liquid ingredients from the receptacle to the mixing chamber.
