Claims12
A method for roasting coffee beans with a roasting apparatus, the roasting apparatus being positioned in a room, and the roasting apparatus comprising:
- a roasting device,
- a smoke treating unit comprising a contaminants treating device configured to treat smoke produced in the roasting device and to prevent a dispensing of air contaminants in the room, the air contaminants including coffee aromas;
- a smoke collecting device connected to the roasting device and configured to collect the smoke produced in the roasting device;
- and
- a smoke diverting device positioned between the smoke collecting device and the contaminants treating device, the smoke diverting device configured to divert a part of the smoke collected by the smoke collecting device away from the contaminants treating device and directly to an outside of the roasting apparatus;
- the method comprising:
- introducing the coffee beans in the roasting device;
- heating the coffee beans during a time;
- and
- diverting, by the smoke diverting device, the part of the smoke away from the contaminants treating device and directly to the outside of the roasting apparatus,
- wherein the part of the smoke produced during the time of the heating step is dispensed in the room without being treated by the contaminants treating device configured to prevent the dispensing of the coffee aromas in the room.
