sivetz coffee sivetz 10lb air roaster

the 10lb air roaster sits in the small production or high-volume sample roasting range at 4.5 kg batch capacity. like all Sivetz machines, it uses pure convective heat transfer with manual control over inlet air temperature and airflow. this gives you direct, responsive control but requires experience to manage profiles effectively. the fixed batch size means you're roasting 10lb batches every time, which works well for consistent production runs but limits flexibility if you need to roast smaller test batches or scale up significantly. roast times are typically faster than drum roasters due to the direct heat transfer method. the stainless steel construction is built to last, and the machine produces less smoke than drum roasters, which can simplify ventilation requirements. best for small roasteries that want the specific cup profile of fluid-bed roasting and have the skill to work with manual controls, or as a secondary roaster for established operations exploring convection roasting methods.
