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.

1. A beverage dispenser for partially frozen beverages, comprising: at least one bowl for storing a beverage product;a freezing cylinder positioned in the bowl;a cooling system for supplying a cooling medium to the freezing cylinder to cool the beverage product when stored in the bowl;a dispenser assembly for dispensing the beverage product from the bowl near a front of the beverage dispenser;an auger which rotates about the freezing cylinder, the auger including a first end positioned near the front of the beverage dispenser and a second end positioned near a rear of the beverage dispenser, and the auger defining a rear end portion at the second end of the auger with the rear end portion of the auger defining an internal cavity with a generally cylindrical volume, with multiple teeth extending from a wall surface of the internal cavity;a driven hub that is positioned on and adjacent an external surface of the freezing cylinder and rotates around the freezing cylinder, the driven hub engaging the multiple teeth of the rear end portion of the auger; anda driver hub that 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;wherein the auger and the driven hub are configured to slide along the length of the freezing cylinder, thus facilitating the removal of the auger and the driven hub from the freezing cylinder. 2. The beverage dispenser as recited in claim 1, wherein the driver hub is operably connected to a motor. 3. A beverage dispenser, for partially frozen beverages, comprising: at least one bowl for storing a beverage product;a freezing cylinder positioned in the bowl;a cooling system for supplying a cooling medium to the freezing cylinder to cool the beverage product when stored in the bowl;a dispenser assembly for dispensing the beverage product from the bowl near a front of the beverage dispenser;an auger which rotates about the freezing cylinder, the auger including a first end positioned near the front of the beverage dispenser and a second end s positioned near a rear of the beverage dispenser, and the auger defining a rear end portion at the second end of the auger;a driven hub that is positioned on and adjacent an external surface of the freezing cylinder and rotates around the freezing cylinder, the driven hub engaging the rear end portion of the auger; anda driver hub that 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;wherein the rear end portion of the auger defines an internal cavity with a generally cylindrical volume, with multiple teeth extending from a wall surface of the internal cavity for engaging the driven hub;wherein the driven hub defines alternating cogs and pockets along its periphery, such that the multiple teeth that extend from the wall surface of the internal cavity in the rear end portion of the auger extend into the pockets; andwherein the auger and the driven hub are configured to slide along the length of the freezing cylinder, thus facilitating the removal of the auger and the driven hub from the freezing cylinder. 4. The beverage dispenser as recited in claim 1, wherein the auger is a unitary member. 5. The beverage dispenser as recited in claim 4, wherein the auger is molded from a thermoplastic material. 6. The beverage dispenser as recited in claim 1, wherein the auger includes a helical flange. 7. The beverage dispenser as recited in claim 6, wherein the auger further includes at least two longitudinal ribs that extend the length of the auger. 8. The beverage dispenser as recited in claim 6, wherein, at the first end of the auger, the helical flange terminates in a cylindrical member that defines an internal cavity for receiving a boss extending from a front surface of the freezing cylinder. 9. A beverage dispenser for partially frozen beverages, comprising: a first bowl for storing a first beverage product;a first freezing cylinder positioned in the first bowl;a first auger which rotates about the first freezing cylinder, the first auger including one end positioned near a front of the beverage dispenser and another end positioned near a rear of the beverage dispenser, and the first auger defining a rear end portion at the end of the first auger positioned near the rear of the beverage dispenser with the rear end portion of the first auger defining an internal cavity with a generally cylindrical volume, with multiple teeth extending from a wall surface of the internal cavity;a first driven hub that is positioned on and adjacent an external surface of the first freezing cylinder and rotates around the first freezing cylinder, the first driven hub engaging the multiple teeth of the rear end portion of the first auger;a first driver hub that is positioned inside of the first freezing cylinder and is magnetically coupled to the first driven hub, such that rotation of the first driver hub causes a corresponding rotation of the first driven hub;a first dispenser assembly for dispensing the first beverage product from the first bowl near the front of the beverage dispenser;a second bowl for storing a second beverage product;a second freezing cylinder positioned in the second bowl;a second auger which rotates about the second freezing cylinder, the second auger including one end positioned near a front of the beverage dispenser and another end positioned near a rear of the beverage dispenser, and the second auger defining a rear end portion at the end of the second auger positioned near the rear of the beverage dispenser, with the rear end portion of the second auger defining an internal cavity with a generally cylindrical volume, with multiple teeth extending from a wall surface of the internal cavity;a second driven hub that is positioned on and adjacent an external surface of the second freezing cylinder and rotates around the second freezing cylinder, the second driven hub engaging the multiple teeth of the rear end portion of the second auger;a second driver hub that is positioned inside of the second freezing cylinder and is magnetically coupled to the second driven hub, such that rotation of the second driver hub causes a corresponding rotation of the second driven hub;a second dispenser assembly for dispensing the second beverage product from the second bowl near the front of the beverage dispenser; anda cooling system for supplying a cooling medium to the first freezing cylinder and the second freezing cylinder to cool the first beverage product stored in the first bowl and the second beverage product stored in the second bowl;wherein the first auger and the first driven hub are configured to slide along the length of the first freezing cylinder, thus facilitating the removal of the first auger and the first driven hub from the first freezing cylinder, and wherein the second auger and the second driven hub are configured to slide along the length of the second freezing cylinder, thus facilitating the removal of the second auger and the second driven hub from the second freezing cylinder.
