ABSTRACT Apparatus for roasting small quantities of coffee (typically less than two kilograms) includes a roasting chamber with base and cylindrical wall portions in fixed relation to each other, Disposed coaxially within the chamber is a downwardly extending tube that has an outlet orifice spaced from the base surface, and an exhaust outlet is in the upper portion of the chamber. A stream of hot roasting gas flowed downwardly through the central tube at high velocity for impact on the base surface and deflection radially outwardly and then flow upwardly through the exhaust outlet at the top of the chamber produces a toroidal circulation pattern of fluidized coffee beans with rapid and uniform roasting of the green coffee, in a simple and compact arrangement in which roasting parameters (such as fluid temperature and cycle duration) may be easily adjusted depending on the degree of roast desired.
