Enhanced Cold Room: A flexible system that allows the existing storage chamber and its refrigeration equipment to be used for light pre-cooling followed by storage. |
Natural Airflow Cold Room – Mist Atmosphere: A specialized chamber where natural air circulation combined with fine misting maintains optimal humidity and gentle air movement for highly sensitive produce. |
Low-Airflow Cold Room with Continuous Water Circulation: Designed for products requiring very high humidity and low air movement (<25 air exchanges/hour). Humidity is maintained through continuous water flow. |
Ethylene Removal: Use of ethylene absorbers is recommended to slow aging and prevent yellowing. |
IMPORTANT TIPS
- Handle fennel carefully at all stages of post-harvest processing.
- Store fennel in low, shallow layers to avoid compression damage.
- Use ethylene absorbers within the storage chamber.
- Maintain high CO₂ levels, as they help retain leaf color and reduce deterioration.
- Manage CO₂ concentration carefully to maintain internal balance and prevent off-odors.
- Use modified atmosphere packaging (MAP) to extend freshness and shelf life.
