Leafy spices: 40–50°C
Seeds/bark (cinnamon, pepper): 45–60°C

High temperatures can cause essential oils to evaporate, affecting their aroma and value.

Drying Time

6–24 hours, depending on the material
Controlled humidity & airflow

Cooling & Conditioning

Prevent moisture reabsorption
Stabilize product quality

Grinding / Packaging(High added value)

Powder processing
Blending
