Natural Airflow Cold Room – Mist Atmosphere: Specialized chamber ensuring natural air movement combined with fine misting, ideal for sensitive products that require gentle airflow and high humidity. |
Ventilation: Custom-designed, digitally controlled system for removing gases produced during respiration. |
Controlled Atmosphere (optional): Optimum composition — Oxygen (O₂) 3%–5%, Carbon Dioxide (CO₂) 4%–10%. |
Ozone System: Recommended installation of an ozone generator to reduce microbial load and prevent fungal growth. |
Pallet Arrangement: Maintain 5–10 cm spacing between pallets to allow even temperature distribution and airflow within the chamber. |
IMPORTANT TIPS
- Moderate CO₂ levels help maintain quality and preserve the green color of okra pods, reducing discoloration and surface damage.
- Remove ethylene using absorbers or ventilation.
- Use modified atmosphere packaging (MAP) to extend freshness and prevent dehydration.
- Install ozone devices to control mold and bacteria.
- Avoid storing okra alongside ethylene-emitting products such as tomatoes, melons, or bananas.
