Abstract
A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem is configured to receive and to thermally roast a batch of beans. The air handling subsystem is coupled to the roasting subsystem and includes a blower, a cyclone separator, and a heater. The blower is configured to impart air motion. The air passes through the air handling subsystem. The cyclone separator is configured to remove particulates from the air handling subsystem. The heater is configured to heat the air passing through the air handling subsystem. The heater includes heater windings that are incorporated into the cyclone separator.
