Claims1
A method for roasting coffee beans comprising the steps:
- roasting said coffee beans in a roasting chamber at a temperature equal to or less than 500° F.;
- removing heated air, smoke, and chaff out of said roasting chamber;
- sending said heated air, said smoke, and said chaff into a catalyst preheater wherein said chaff falls into a collection bin and said heated air is heated or cooled to a predetermined temperature;
- sending said heated air and said smoke across a heating element to bring said catalytic converter up to a temperature for combustion;
- detecting said catalytic converter firing and lowering the temperature of a catalytic converter as desired;
- consuming said smoke by traveling through said catalytic converter;
- detecting the temperature of said heated air and lowering or raising said heated air as desired;
- and
- routing said heated air back to said roasting chamber.
