ABSTRACT:
A coffee roaster suitable for use in the home and/or retail establishments includes a container where initially green unroasted coffee beans are levitated while heated air is forced through the beans to roast the beans to a desired degree. The container is shaped to allow continuous rotation of the beans to avoid charring and uneven roasting. The warm air is circulated in a closed circulation loop and, after roasting is completed, cool ambient air is circulated through the beans to cool them. An optional companion grinder is provided to grind the fresh roasted beans for immediate coffee brewing.
