On the other hand, Patent Document 2 discloses a raw-bean roasting mechanism of a coffee machine. That is, Patent Document 2 discloses a raw-meat roasting mechanism of a coffee machine comprising a kettle in which green beans are stored, a stirring means rotatably mounted inside the kettle, a heating means for heating the beans, and a cover body .

However, in Patent Document 2, there is a problem that the roasting efficiency is significantly lowered because the heater means for roasting the green bean is formed separately from the kettle. And the separation of the silver skin, which is separated from the green bean during the roasting process, is not properly performed, so that it is difficult to extract high quality coffee beans.

On the other hand, coffee machines can cause smoke in roasting the green beans. Such smoke may contaminate the room, and when the amount of generated smoke is excessive, there is a problem that the user's unpleasantness or the health of the user may be deteriorated.
