ABSTRACT:
An apparatus for roasting coffee beans or the like includes a controlled spinning bed or fluid bed roaster in combination with a cyclone separator for removing chaff from the heating medium. The cyclone separator is disposed above and in coaxial and abutting relationship with the roaster. The separator has a generally cylindrical shape with a plate having a plurality of louvers in the base thereof. The louvers impart rotational movement as the heating medium passes therethrough so that the chaff can be removed therefrom. In a preferred embodiment of the invention, a second centrifugal separator which is relatively small with respect to the first separator is disposed adjacent the first separator for making a final separation and returning the heated medium to the roaster.
