Which Roaster Type Maximizes Throughput: Air-Motion or Solid Drum?
You’re staring at two machines. They look powerful. You know throughput—the amount of coffee you can roast per hour—is critical. But which type truly wins? In this blog, you’ll see how an air‑motion roaster vs a solid drum design stacks up in throughput, efficiency, and roast consistency. You’ll get a clear picture of which roaster type might be best for your roasting goals. Keep reading—your next batch size decision could depend on it. What Frustrates Roasters Most About Throughput? Time. Heat transfer. Bean uniformity. You might have a machine that can roast a big load, but if some beans lag behind or some overheat, your yield drops. So throughput isn’t just about size—it’s about consistency at speed… You want a design that tackles bottlenecks: poor heat exchange, uneven roasting, and cooling delays. Each roast cycle that drags or fails costs you real dollars. Why Might Air‑motion Methods Roast Faster? Because they put beans in suspension—air lifts and moves each one so heat re...
