<p>A roasting apparatus (20) for coffee beans and other food includes a removable drum (64) on the housing rotatable about a horizontal axis and drive means on the housing for supporting and rotating the drum (64). The drum (64) has a plurality of internal vanes (114) arranged such that (i) as the drum (64) is rotated in one direction the beans are stirred and retained by the vanes (114) within the drum (64), and (ii) as the drum (64) is rotated in the opposite direction the beans are moved by the vanes (114) toward the drum (64) opening for dispensing from the roasting apparatus (20). A removable cover (24) includes a safety interlock (140) which, when activated, prevents opening of the cover (24) when the drum (64) is at bean roasting temperature and which automatically deactivates upon cooling of the drum (64) to permit opening of the cover (24) to remove the drum (64). A chaff collector (26) has an opening for alignment with the drum opening and a lip (128) which is captured by the cover (24) when the cover (24) is in the closed position, and is non-removable from the roasting apparatus housing when the cover (24) is in the closed position. The chaff collector (26) includes a baffle (124) for deflecting chaff into the chaff collection portion while permitting dispensing of the beans out of the roasting apparatus.</p> |
