Roasting Methods MOC¶
Roasting method refers to both the equipment type used to apply heat and the approach to controlling heat transfer throughout the roast. The primary equipment categories — drum, fluid-bed, and hybrid — each deliver different ratios of conductive, convective, and radiant heat, which in turn shapes how flavour develops. Profile approach (the sequence of temperatures and airflow decisions across the roast) operates within the constraints of the equipment chosen. This MOC maps equipment types, heat transfer mechanisms, and profile methodologies.
