Corrective profile adjustments

Key Concepts

• Identifying Issues:

• Review defect logs and sensory feedback to pinpoint issues like baked beans, tipping, scorching, or underdevelopment.

• Consider bean origin, moisture content, and batch density as contributing factors.

• Adjusting Heat Application:

• Modify charge temperature, drum or airflow settings to reduce scorching or tipping.

• Adjust rate of rise (RoR) curves to prevent baked or underdeveloped beans.

• Development Time Tuning:

• Extend or shorten time after first crack to adjust roast development.

• Ensure proper balance between Maillard reactions and caramelization.

• Airflow and Drum Speed:

• Increase airflow to cool surface and reduce tipping.

• Adjust drum speed for uniform heat application.

• Iterative Approach:

• Make small, incremental changes and monitor results.

• Document all adjustments and outcomes to refine future profiles.

• Preventative Measures:

• Maintain clean roaster and calibrated probes.

• Ensure consistent green coffee quality and moisture content.

Summary

Corrective profile adjustments involve carefully analyzing defects, tweaking roasting parameters, and iterating based on outcomes. A systematic approach allows roasters to consistently achieve desired roast levels while minimizing defects.
