Drum roasters employ simple technology that hasn’t really changed a whole lot over the years. In a basic sense, the typical drum roaster is just a cylinder rotating on a horizontal axis. Flights, vanes or paddles mix the beans, and heated air moves through the drum and removes the roasting by product.
Drum roasters are especially popular in the specialty coffee industry because of the manual control options. Indeed those who enjoy the artistic side of the roasting process almost invariably use a drum roaster.
At The Coffee Cube, we bring over 15 years of drum roasting technology to Hong Kong.
