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 rotating in the horizontal plane. 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. The oven chamber includes an upper transparent section through which the roasting charge of beans may be viewed and thereby allow manual control of the process in response to visual observation.
