Sivetz 1lb Air Roaster

the verdict

the 1lb air roaster is a sample roasting tool, not a production machine. at 0.45 kg fixed batch size, it's built for cupping and quality control work where you need to evaluate green coffee or replicate production roasts at small scale. the manual controls are straightforward: you manage inlet air temperature and airflow directly, and the fluid-bed design gives you a clear view of bean color development. it's not adjustable for smaller or larger batches, so you're locked into that 1lb capacity. useful for roasteries that need a dedicated sample roaster or for quality labs doing evaluation work. the fixed batch size can be limiting if you need flexibility, and manual operation means you're tied to the machine during the roast. durable stainless steel construction typical of Sivetz, and parts availability is solid.
