Food processing apparati including magnetic drives are described herein. According to one exemplary embodiment, a food processing apparatus may include a motor having a motor shaft, a rotor rotatably mounted on the motor shaft, and a stator producing an electromagnetic field for interacting with the rotor. The rotor may magnetically drive a drive plate coupled to an impeller inside a food-contact chamber.
