PROBLEM TO BE SOLVED: To provide an air circulation system of a roaster, by which a uniform air flow cycle is formed inside the roaster. SOLUTION: The roaster 100 is equipped with: a first air flow space 10; a second air flow space 20 having an air inlet port 21; a fan bracket 33 that is installed in the second air flow space 20 and provided with an inlet port 31 and an outlet port 32; a fan 30 installed inside the fan bracket 33: a rotary motor 40 for driving the fan 30; a board 50 for placing a baking plate 70 thereon; an electric heater 60 fixed on a holding base 51 of the board 50; and the baking plate 70 in which an oil discharge port 71 is formed. In the roaster 100, air flowed in the second air flow space 20 through the air inlet port 21 by the rotation of the fan 30 is passed through the fan bracket 33 and made to flow in the inner space of the roaster 100. The air is then exhausted from the oil discharge port 71 of the baking plate 70 and again flowed in the second air flow space 20 through the air inlet port 21. COPYRIGHT: (C)2008,JPO&INPIT
