Abstract
A roasting chamber for roasting green coffee beans with a heated air current flowing from a lower air inlet region to an upper air outlet region of the roasting chamber, includes a roasting-waste settling chamber disposed in the air outlet region, the settling chamber being in the form of a substantially horizontal annular receiving trough having a substantially vertical central air inlet opening formed therein, an air-permeable and coffee-waste particle-impermeable filter covering the receiving trough, and a supplemental cup-shaped trough disposed concentrically below the receiving trough, the cup-shaped trough having a larger diameter than the air inlet opening and having an edge region disposed at a distance from the receiving trough defining a radial air passage therebetween.
