ABSTRACT:
A coffee roaster which roasts coffee beans in an oven chamber employing both radiant and convection heating techniques while the beans are continually intermixed in a fluidized bed. Roaster control means are provided to terminate the roasting process by quenching the beans and oven chamber while maintaining the beans in a fluidized bed to avoid scorching or further roasting by the residual heat of the coffee bean mass.
