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.
