Abstract
A beverage dispenser for partially frozen beverages includes at least one bowl for storing a beverage product, with a freezing cylinder positioned in the bowl. The beverage dispenser further includes a cooling system for supplying a cooling medium to the freezing cylinder to cool the beverage product when stored in the bowl, along with a dispenser assembly for dispensing the beverage product from the bowl. The beverage dispenser includes an auger which rotates about the freezing cylinder. A driven hub is positioned on and rotates with respect to the freezing cylinder, and the driven hub engages a rear end portion of the auger. A driver hub is positioned inside of the freezing cylinder and is magnetically coupled to the driven hub, such that rotation of the driver hub causes a corresponding rotation of the driven hub, and thus, rotation of the auger.
