General Tips for Dates

Storage temperatureRelative Humidity (RH)DurationPre-coolingSensitivity to ethyleneEthylene ProductionControlled Atmosphere
Storage temperature: 0° C
Relative Humidity (RH): 82%-87%
Duration: 8-12 weeks
Pre-cooling: Air cooling
Sensitivity to ethylene: Moderate
Ethylene Production: Low
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.

IMPORTANT TIPS
  • 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.
