ABSTRACT:
A coffee bean roaster is provided with a cylindrically shaped transparent viewing tower in which coffee beans are roasted by an upwardly directed hot gaseous stream while being fluidized into a visually pleasing ascending central and descending outside columns during the roasting cycle. A two way valve located at the bottom of the tower permits the gaseous stream to enter the tower when the valve is in a first position and the roasted beans to be diverted to a cooling chamber when the valve is in a second position.
