<p>CONTROLLED COFFEE ROASTING A coffee roasting method permitting control of final product properties is disclosed. Gases, usually air and combustion gases, are heated to a temperature selected from the range between 200.degree.C and about 240.degree.C. A bed of coffee beans is suspended in a bubbling bed by the heated gas and maintained that way for about 2 minutes to about 10 minutes. The roasted coffee beans are subsequently discharged from the bubbling bed and cooled. The density of the roasted coffee beans is determined by the specific roasting conditions selected.</p> |
