    • Disclosed herein are a roasting apparatus and a method of controlling a roasting apparatus, and more particularly, are a roasting apparatus in which an object is stirred and roasted in a roasting chamber, and a method of controlling the roasting apparatus.
      The roasting apparatus for heating an object includes a roasting chamber part which includes a cylindrical roasting chamber, in which an object is stirred and which extends in a vertical direction, and a rotary stirring part rotated to stir the object accommodated in the roasting chamber, wherein the rotary stirring part is rotated about a stirring axis formed in the vertical direction; a casing unit configured to surround the roasting chamber part; a heat source part including a first heat source part configured to provide radiant heat to the roasting chamber part; and a radiant temperature measurement unit configured to measure a temperature of the roasting chamber or the object and a chamber outer space temperature of a chamber outer space between the casing unit and the roasting chamber part on the basis of infrared rays emitted from an inner surface of the roasting chamber part or a surface of the object, which is heated by the heat source part, wherein a preheating operation is performed until the chamber inner temperature of the roasting chamber and the chamber outer space temperature reach a preset reference chamber inner temperature and a preset reference chamber outer space temperature.
