Dynamic Pre-Cooling (High-Suction Capacity Units): Specialized study of heat absorption time and airflow velocity ensures uniform temperature reduction throughout the product mass. Used for both packed and unpacked tomatoes, pre-cooling delays ripening and significantly extends shelf life. |
Pallet Arrangement: To ensure uniform temperature during storage, maintain 5–10 cm gaps between pallets, aligned with the airflow direction of cold air circulation. |
IMPORTANT TIPS
- Rapid pre-cooling at 14°C in Dynamic Pre-Cooling Units, followed by continuous cold chain maintenance across all stages of handling and transport.
- Dynamic Cooling is essential for optimal preservation and extended storage duration.
- Do not store tomatoes alongside ethylene-producing fruits such as apples, pears, peaches, or nectarines.
- Avoid temperatures below 8°C, as chilling injury may occur — leading to surface pitting, poor color development, and internal breakdown.
- Degreen in Dynamic Degreening Chambers, applying ethylene to maintain a steady concentration of 100–150 ppm throughout the process.
- Control CO₂ levels to prolong storage life and preserve quality attributes.
- Store tomatoes at the lower threshold of physiological ripeness (third green stage) before degreening for optimal post-harvest performance.
