Manual or open-loop roasting leads to thermal variability and batch-to-batch flavor inconsistency. Automating control ensures precise adherence to target temperature curves regardless of environmental fluctuations.

Inconsistent flowering intervals in Rubiaceae species prevent synchronized harvesting and industrial processing. Stabilizing the reproductive timeline ensures predictable yield cycles and resource allocation.

Uneven heat distribution and residual byproduct accumulation lead to non-uniform roast profiles. Standardizing thermal transfer ensures repeatable flavor profiles and prevents batch contamination.
