ABSTRACT:

For example, coffee beans are uniformly roasted within a relatively short time and cooled in a similar but separate chamber with or without an intermediate quench. A movable bean spill which is movable upwardly or downwardly into engagement with the spinning bed is provided for directing a portion of the beans out of the bed inwardly and downwardly to increase the mixing of the beans. The movable beam spill includes a compound surface defined by a two-dimensional surface.
