Air roasting consistency for a specified roast
The purpose of a roaster is to roast quality beans to a precisely specified roast. Most beautique roasters simply can not deliver an exact roast level with a drum roaster. Each bean is going to come into contact with the scorching drum surface differently. Air roasting is the only way to ensure each bean is roasted to exactly the specified roast level and the Sivetz fluidized-bed air roaster does this best.
