Section 1: The Science and Art of Coffee Roasting

Coffee roasting involves applying heat to transform green coffee beans into the rich, flavorful ones we brew. Heat and airflow work together to enhance the taste and aroma.

Key Scientific Processes:

Drying phase (100–160°C): Moisture is evaporated.

Maillard reaction (160–180°C): Sugars and amino acids react, producing color and aroma.

First crack (196–205°C): Gases escape, beans expand. This is the benchmark for most medium roasts.

Development phase: Controls the final flavor.

Second crack (215°C+): For dark roasts. Oils rise to the surface; bitterness may increase.

Precision in each stage is critical. That’s why high-quality, programmable roasting equipment is a must for commercial applications.

Section 2: Why Roasting Equipment Is Business-Critical

If you’re in the coffee business, your roasting machine is your production backbone. An inconsistent or poorly constructed machine can lead to:

Undesirable flavor variations

Bean scorching or tipping

Inefficient energy use

Safety hazards

Customer dissatisfaction

On the other hand, a well-built commercial coffee roaster machine can provide:

✅ Stable and repeatable roast curves
✅ Accurate temperature and airflow control
✅ Integrated cooling and smoke control
✅ Long service life with minimal maintenance

At Yetinhon, we’ve helped hundreds of new and expanding coffee businesses choose the right roaster based on volume, budget, and goals. We’ve seen firsthand how the right equipment leads to better quality, smoother workflows, and stronger customer retention.
