Abstract
An iced-beverage making machine comprises a tank (11) to contain the beverage, a mixer (12) to stir the beverage in the tank and a refrigerating circuit (14) to cool the beverage in the tank. The mixer is connected by a magnetic joint to a movement reduction motor (13). The magnetic joint comprises a driving portion (16) which is provided with a crown of first magnets (22) and is connected to the reduction motor (13), and a driven portion (17) which is provided with a crown of second magnets (21) and is connected to the mixer and magnetically driven in rotation by the driving portion. Close to the two magnet crowns there is the presence of means (23, 24) for detecting the angular phase displacement of the two crowns relative to the angular position of maximum attraction between the magnets, the detecting means sending a disabling signal (26) to the refrigerating circuit when the detected angular phase displacement exceeds a preestablished value. In this manner, density of the produced iced beverage is adjusted.
