Dynamic Pre-Cooling (High-Suction Capacity Chambers): Designed to ensure even temperature distribution by regulating air velocity and cooling rate until the core temperature of the product is reached. Suitable for both packaged and unpackaged zucchini. |
Reinforced Cold Room: A flexible system that allows the same refrigeration chamber and its mechanical equipment to be used for light pre-cooling and subsequent storage. |
Low-Airflow Cold Room with Continuous Water Circulation (for zucchini with blossoms): Specialized design for products requiring high humidity and gentle air circulation (less than 25 recirculations per hour), maintained through continuous water flow. |
IMPORTANT TIPS
- Low-airflow water-circulated cold rooms are ideal for zucchini with blossoms. Alternatively, protect blossoms from direct cold air by placing crates as air buffers.
- Pre-cool rapidly in Dynamic Pre-Cooling systems and maintain the cold chain throughout all handling and transport stages.
- Pre-cool in a reinforced cold room and continue storage in the same chamber to maintain product quality and prevent fungal or bacterial decay.
- Keep CO₂ levels at moderate levels to help preserve freshness.
- Use modified atmosphere bags to extend shelf life.
- Avoid storage with ethylene-emitting products.
- Disinfect equipment and cold rooms before each use.
