<p>A novel rotor is provided for attachment to the lower end portion of the motor-driven shaft of a liquidmixing device, such as a liquifier or mixer commonly used in the preparation of milkshakes, malts and like ice cream mixes. The rotor features a one-piece element in the form of a V having a flat bottom and a pair of upwardly and outwardly divergent arms providing mixing blades related in diametrically opposed fashion. A disk having a central opening receives the shaft and is disposed in radial plane spaced axially above the flat bottom and its periphery is affixed to the terminal upper ends of the blade arms. The disk has an annular flange which presents a smooth circular surface that prevents the blades from damaging the mix container during operation of the mixer as well as during removal of the container while the shaft and rotor are still rotating.</p> |
