Dynamic Cooling: Monitors and regulates storage conditions at multiple points throughout the chamber volume, maintaining optimal parameters continuously over 24 hours. This system extends product shelf life by 15–20% compared to standard conditions.
Curing (Skin Hardening): A critical step prior to long-term storage. It can be performed either inside the existing cold room using added drying mechanisms or in specialized curing chambers at 22°–26°C and 70%–75% RH for 4–5 days.
Pallet Placement: To achieve uniform temperature distribution, maintain gaps of 5–10 cm between pallets in line with cold air circulation.
IMPORTANT TIPS
Dynamic Cooling is essential for maintaining quality and prolonging storage life.
Ensure the rhizomes are properly cured before cold storage to prevent surface damage and decay.
Monitor storage temperature — do not allow it to drop below 12°C, as chilling injury can occur (discoloration, cracking, sunken spots, mass shrinkage, and softening of tissue).
Maintain relative humidity between 65% and 90%:
Below 65% causes dehydration and shrinkage.
Above 90% promotes sprouting; above 95% leads to tissue breakdown and darkening.
Install ozone generators to control fungal growth and microbial load.
