What is the Difference between Air Roasting and Cylinder Roasting?
Hot-air roasted coffee is roasted in a large vertical standing machine. The coffee is consistently moved with hot-air heated by natural gas. This system is also known as a fluid bed roaster. While the beans are moving evenly in the roasting chamber, light impurities (sticks, chaff, and smoke) are blown away into a compartment above called a chaff cyclone. This roasting method is unrivaled in its consistency and cleanliness. Cylinder roasted coffee is roasted in a large horizontal machine that rotates over a hot flame. When the roast is done, beans are released into a large cooling trough.
