Dynamic Pre-Cooling (Low Atmospheric Pressure – Wet Bulb Chambers): Specialized chambers for unpackaged celery immediately after harvest. They regulate humidity and pressure to achieve rapid, uniform temperature reduction. |
Cold Room with Natural Airflow and Nebulized Atmosphere: Combines gentle air movement with mist humidification to maintain high humidity levels for moisture-sensitive produce. |
Low-Airflow Cold Room with Continuous Water Circulation: Designed for very high humidity storage (<25 air changes/hour), using continuous water flow to maintain leaf freshness and prevent dehydration. |
IMPORTANT TIPS
- Dynamic Cooling is essential for maintaining product quality during storage.
- Perform rapid pre-cooling in Dynamic Pre-Cooling Units and ensure cold chain continuity at every handling stage.
- Avoid storing celery with ethylene-producing fruits such as apples, pears, melons, or peaches above 5°C, as ethylene accelerates leaf yellowing and quality loss.
- Install ozone generators to prevent fungal development.
- Avoid high CO₂ concentrations, as they can cause leaf yellowing and reduced visual quality.
