Key Concepts
-
Heat Recovery:
-
Capture heat from exhaust gases to preheat incoming air or beans.
-
Use afterburners efficiently to reduce fuel consumption.
-
Insulation and Sealing:
-
Properly insulate drum and airflow channels to minimize heat loss.
-
Seal doors, hatches, and joints to prevent energy leaks.
-
Roasting Profiles:
-
Optimize roasting curves to achieve desired roast levels with minimal energy input.
-
Reduce idle or over-roasting periods to save energy.
-
Equipment Selection:
-
Choose burners, fans, and motors with high efficiency ratings.
-
Consider variable-speed drives for motors to match energy usage to demand.
-
Operational Practices:
-
Schedule batch sizes to maximize roaster utilization.
-
Perform regular maintenance to maintain efficiency.
Summary
Applying energy efficiency strategies in roasting not only cuts costs but also supports sustainable coffee production by reducing carbon footprint and resource consumption.
