Abstract: A mixing machine for ice cream shakes and malts comprising a base platform and coupled back wall for partially enclosing the mixing area of the malt or shake. At least one mixing arm is provided within the area and projects downward above the platform to enable insertion within a malt container. A fluid conduit and elongated dispensing opening is provided to establish a thin layer of water across the surface of the back wall, thereby developing a flowing liquid barrier between the mixing arm and the surface of the back wall.
