<p>The device for roasting coffee beans, comprises a roasting container (1) formed by a rotor bowl (2) and a stationary lid device (3), a driving device for rotating the rotor bowl relative to the lid device around an axis, an air heater (5) connected over a supply channel with the roasting container and arranged above the rotor bowl, a recirculation device connected with the additional channels (6, 7) and/or the supply channel, guide blades arranged in the lid device, a gap formed between the rotor bowl and the lid device, and a mold produced from sheet metal. The device for roasting coffee beans, comprises a roasting container (1) formed by a rotor bowl (2) and a stationary lid device (3), a driving device for rotating the rotor bowl relative to the lid device around an axis, an air heater (5) connected over a supply channel with the roasting container and arranged above the rotor bowl, a recirculation device connected with the additional channels (6, 7) and/or the supply channel, guide blades arranged in a lid interior of the lid device, a gap formed between the rotor bowl and the lid device, a mold produced from sheet metal, and a filler tube led by the mold. The heater and the supply channel are component of the lid device with vertical axis. The supply channel is vertically arranged in the area of a lid opening, through which the hot air enters into the roasting container, and is axis-symmetrically arranged to the rotor axis of the rotor bowl. The supply channel is circularly surrounded by additional channels, by which the exhaust airflow is conducted. The recirculation device has regulation flaps to supply process exhaust airflow to different supply channel. The regulation flap is arranged in an inlet connection piece of the heater. The multi-walled rotor bowl is formed and has an inner bowl produced from sheet metal. The exchangeable inner bowl is surrounded by a double-walled insidely insulated outer bowl. The mold is intended in a head area of the roasting container. The mold is connected with the lid device and has an interval for lid interior for the formation of an exhaust channel for process exhaust airflow. The truncated cone shaped exhaust channel has a circular cross section and is connected with one of the additional channel. The lid device has a discharge opening, which is arranged in the area of the guide blades. The discharge opening is connected over an outlet channel with a fluidized bed cooler. An independent claim is included for a procedure for operating a device for roasting coffee beans.</p> |
