  • Apparatus and method of dispensing particulate ice and cold beverage with irreversible separation of cooling ice
    Patent number: 4803850
    Abstract: A method of and apparatus for dispensing both particulate ice and cold beverage wherein a common supply of ice is used firstly for dispensing and then secondly for cooling of the beverage. A pair of co-axial rotors are co-rotated about a common vertical axis by a single motor, the upper rotor dispenses particulate ice off of an annular upper bottom. All ice that falls through the open center of the upper bottom irreversibly falls down upon a cold plate and the lower rotor moves the fallen cooling ice on the cold plate for enhanced cooling.
