Dynamic Cooling: Maintains ideal storage parameters at multiple points throughout the chamber 24/7, ensuring uniform conditions across the entire volume. Dynamic Cooling delivers superior product quality and extends storage life by 15%–20% beyond standard conditions.

Pallet Arrangement: Maintain 5–10 cm spacing between pallets in the direction of airflow to ensure consistent temperature distribution throughout the storage area.

IMPORTANT TIPS
  • Dynamic Cooling is essential for long-term potato storage.
  • Ensure skin curing (suberization) before harvest — the skin must be firm and resistant before storage.
  • Do not store potatoes harvested above 25°C; they will lose moisture and become soft. Such lots should be sold immediately.
  • Cover exposed piles of stored potatoes with breathable materials (e.g., seed sacks, not tarps) to protect from light, humidity, and excess airflow.
  • Avoid light exposure during storage — it causes greening and solanine formation.
  • Potatoes stored at temperatures below the optimum may convert starches into sugars; this can be reversed by gradually warming them to 12–25°C over 10–12 days.
  • During loading, maintain 12°C until all batches are stored. Then, lower to 8°C for one week, and finally stabilize at 6–7°C for long-term conservation.
  • Use approved sprout inhibitors to prevent sprouting during extended storage.
