The inventive process comprises micro-processing means utilizing a coffee roaster control algorithm for controlling the roast process of coffee beans. The algorithm utilizes curve fitting techniques to calculate polynomial coefficients used in generating a smooth curve to control the coffee bean temperature during the roast process. Through the use of multiple set points and actual historical data, the polynomial coefficients are generated. The coefficients are then used to plot a graph that indicates the path the roast process will try and maintain.

A coffee roaster that includes a combustion chamber and a connected roasting oven in which the heating gases for roasting the coffee beans are recirculated to the combustion chamber wherein the coffee bean chaff is separated from the recirculating heating gases prior to venting to atmosphere, and an associated cooling chamber wherein the roasted coffee beans are cooled in a two-stage-heating cycle wherein the cooling air is recirculated to the combustion chamber to be reheated to roasting temperatures and vented to atmosphere during the second stage of cooling.

A fluidized bed coffee roaster controls air flow and/or temperature to maintain a desired time-temperature roast profile. The roaster may also provide a two stage quenching cycle for rapidly cooling roasted coffee beans to ambient temperature. In a first stage of the quenching cycle unheated air is passed through the roasted beans while they are still in the roasting chamber of the fluidized bed roaster. In a second stage of the quenching cycle which is carried out outside of the roasting chamber, in a fluidized bed quenching station, unheated air is flowed through, and fluidizes, the roasted coffee beans cooling them to ambient temperature.

A coffee bean roasting machine of the type having a cyclone separator heating chamber and a coffee bean roasting chamber in a recirculating process stream driven by a recirculation fan is operated to air cool the roasted coffee beans in the roasting chamber, to a temperature beneath which the beans give off smoke, while at the same time incinerating smoke removed from the roasting chamber. A purge gate in ducting between the cyclone separator and the roasting chamber is opened to allow the flow of ambient air into and through the roasting chamber while blocking flow out of the cyclone separator, so that ambient air is directed through the roasting chamber. The smoke and any airborne particulate material from the roasting chamber are carried into the heating chamber and through the incineration tube, where they are incinerated. Preferably the system and process are operated automatically by a computer and programming.
