|
Dynamic Pre-Cooling (Low Atmospheric Pressure – Wet Bulb Chambers): Specialized units for unpackaged arugula leaves immediately after harvest. These systems regulate relative humidity and create low pressure, ensuring rapid and uniform temperature reduction. |
Dynamic Pre-Cooling (High-Suction Capacity Chambers): Engineered for packaged products, ensuring uniform airflow and temperature distribution throughout the product mass. |
Cold Room with Natural Airflow and Nebulized Atmosphere: Combines natural air movement with mist humidification to maintain ideal humidity and protect delicate leaves from dehydration. |
Low-Airflow Cold Room with Continuous Water Circulation: Designed for products requiring very high humidity, maintaining consistent moisture through continuous water flow and reduced air recirculation (<25 air changes per hour). |
- Perform rapid pre-cooling in Dynamic Pre-Cooling Units and maintain the cold chain throughout storage and transport.
- Avoid storing arugula with ethylene-producing fruits such as apples, pears, peaches, and nectarines.
- Control CO₂ levels — concentrations up to 10% effectively slow leaf yellowing.
- Remove ethylene using absorption or ventilation systems.
- Use Modified Atmosphere Packaging (MAP) to extend freshness and shelf life.
- Install ozone generators to inhibit fungal growth and maintain hygiene.
