Ethylene Production: Very low
Controlled Atmosphere: Not recommended

Dynamic Pre-Cooling (Low Atmospheric Pressure – Wet Bulb Chambers): Specialized pre-cooling chambers for unpackaged radicchio immediately after harvest. These systems maintain optimal humidity while creating low atmospheric pressure for rapid temperature reduction and uniform cooling.

Dynamic Pre-Cooling (High-Suction Capacity Chambers): Ensures even air distribution and uniform cooling throughout the product mass, suitable for both packaged and unpackaged produce.

Dynamic Cooling: Regulates all key storage parameters—temperature, humidity, and air circulation—continuously across the chamber, maintaining stability 24/7. This process extends product shelf life by 15–20% beyond conventional storage conditions.

IMPORTANT TIPS
  • Dynamic Cooling is essential for optimal radicchio preservation.
  • Perform rapid pre-cooling in Dynamic Pre-Cooling Units and maintain a continuous cold chain during all handling and transport stages.
  • Avoid storing radicchio with ethylene-producing products — ethylene exposure accelerates leaf darkening, fungal decay, and discoloration of white stalks.
  • Remove ethylene using absorbers or proper ventilation systems.
  • Use Modified Atmosphere Packaging (MAP) to maintain crispness and color.
  • Install ozone generators to suppress fungal growth and extend storage life.
