Abstract
The roasting body is composed of a roasting body, a rotary drum supported on the inside of the roasting body to rotate in a horizontal attitude to accommodate and stir the coffee beans, infrared heaters disposed on the inner wall surface of the roasting body to surround the rotary drum in order to heat the coffee beans accommodated in the rotary drum by radiant heat, and a circulating path to circulate the hot air in the rotary drum into the roasting body in order to utilize the thermal energy effectively.
