82%-87%
|
Duration:
8-12 weeks
|
Pre-cooling:
Air cooling
|
Sensitivity to ethylene:
Moderate
|

|
Controlled Atmosphere:
Recommended
|
Storage Temperature: Recommended storage temperature is 0 °C. |
High Humidity: Use an air cooler with a low temperature differential (ΔT) between the inlet and outlet air. |
Storage Duration: Recommended period is 8 – 10 weeks (outside controlled atmosphere conditions). |
Ventilation: Design and install a ventilation mechanism to manage respiratory by-products, particularly carbon dioxide (CO₂). |
Air Recirculation: Install cooling elements with inverter-driven fans, digitally controlled for continuous 24-hour operation. |
Ozone: Installation of an ozone system is recommended to reduce microbial load. |
Controlled Atmosphere: Recommended use of modified atmosphere storage can extend the storage duration up to 26 weeks. |
Dynamic Cooling: Continuously monitors multiple points within the chamber to maintain ideal storage parameters across the entire volume, 24/7. |
- Maintain uniform temperature throughout the storage chamber.
- High CO₂ levels contribute to long-term preservation.
- For the control of insects, fungi, and bacteria, expose the dates to an atmosphere of 100 % CO₂ for 24 hours at temperatures below 5 °C.
- Use modified atmosphere bags to extend storage life.
- Disinfect cold-storage rooms before use.
- Avoid exposure to foreign odors, as dates easily absorb environmental scents.
