ABSTRACT:
A roasting system includes a roasting chamber having an air infeed vent for receiving air and a flue for directing exhaust air from the roasting chamber. An air reconditioning system coupled between the air infeed vent and the flue eliminates the need for external venting. The air reconditioning system includes a heater for heating the air received in the roasting chamber through the infeed vent and an air filtering system. A fan draws the exhaust air from the roasting chamber, passes the exhaust air through the air filtering system and past the heater and then recirculates the filtered and reheated air back into the roasting chamber. Continuously filtering recirculated air allows the roasting system to be placed in retail coffee shops without requiring external ventilation or producing objectionable odors. By reusing the heated air from the roasting chamber, the roasting system is also more energy efficient than current coffee roasting systems and allows the roasting system to be operated in non-industrial locations.
