ABSTRACT:
A machine for preparing and delivering frozen beverages, such as water-ices, comprises a tank (12) for holding and refrigerating the beverage, in which there is an evaporator (16) of a refrigerating circuit and a mixing propeller (18) the rotation axis (19) of which is magnetically coupled, through a tank wall (28), with the rotation axis of an electric reduction motor (21). The magnetic coupling is formed of a first magnetic set (22) external to the tank and driven in rotation by the rotation axis of the reduction motor, and a second magnetic set (23) internal to the tank and connected to the propeller rotation axis. The first and second sets face each other on opposite faces of the tank wall to be magnetically coupled through said wall, the first set (22) thereby driving in rotation the second set (23).
