Cooking appliance coffee roasting pan

A cooking appliance comprising:

• a cabinet defining a cooking chamber;
• a microwave module mounted within the cabinet, the microwave module positioned and configured for delivering microwave energy into the cooking chamber;
• a motor;
• a drive shaft connected to the motor;
• a rotating hub mounted to the drive shaft whereby the motor drives rotation of the rotating hub via the drive shaft;
• a ring assembly rotatably mounted on a floor of the cooking chamber, the ring assembly comprising a central body, an arm extending outward from the central body, and an array of wheels arranged about an outer perimeter of the ring assembly, the ring assembly coupled to the rotating hub at the central body of the ring assembly, whereby rotation of the rotating hub driven by the motor is imparted to the ring assembly;
• a pan defining an internal volume, the pan mounted on the ring assembly for rotation therewith, wherein the wheels of the ring assembly contact the floor of the cooking chamber and the pan, whereby rotation of the pan is driven by the wheels of the ring assembly;
• a rotating plate positioned below the pan with a finger extending downward from the rotating plate, the finger engaged with the arm of the ring assembly;
• and
• a stirrer rod positioned within the internal volume of the pan, the stirrer rod coupled to the rotating hub via the rotating plate and the ring assembly, whereby the stirrer rod rotates with the rotating hub, wherein rotation of the stirrer rod is driven by the engagement of the arm of the ring assembly and the finger of the rotating plate at a first distance from the rotating hub, wherein the pan and the wheels are engaged at a second distance from the rotating hub, the second distance larger than the first distance, whereby the pan rotates at a first speed and the stirrer rod rotates at a second speed greater than the first speed.
