II. Complete Roasting Process
Core Process: Green Bean Preparation → Preheating Stage → Dehydration Stage → Maillard Reaction → First Crack Stage → Development Stage → Cooling
1. Pre-Roasting Preparation
Green Bean Selection: Select high-quality green beans, removing defective beans and impurities.
Equipment Preheating: Preheat the 200kg roaster to 180-200℃.
Parameter Setting: Set the roasting curve according to the characteristics of the bean variety.
2. Core Roasting Stage
Dehydration Stage (4-8 minutes): Temperature 100-150℃, beans turn from green to yellow, releasing a grassy aroma.
Maillard Reaction (3-5 minutes): Temperature 150-180℃, producing nutty and caramel aromas.
First Crack Stage (5-8 minutes): Temperature 180-205℃, beans burst and expand, fruity aromas become prominent.
Development Stage (2-5 minutes): Temperature 205-230℃, flavor compounds fully develop.
3. Roasting Degree Control
Light Roast: Early first crack, bright acidity, retains floral and fruity aromas
Medium Roast: After first crack, balanced sweet and sour, nutty and chocolate flavors
Dark Roast: Second crack stage, rich bitterness, smoky caramel notes
