Storage temperature: 0,2° to 0,5° C

Ethylene Production: Very low
Controlled Atmosphere: Not recommended

Dynamic Pre-Cooling (Low-Pressure / Wet-Bulb Chambers): Specialized pre-cooling units designed for unpackaged vegetables immediately after harvest. They control relative humidity and create low-pressure conditions, ensuring a rapid and uniform drop in temperature.

Dynamic Pre-Cooling (High-Suction Capacity Chambers): Engineered to optimize air velocity and absorption time for consistent temperature distribution throughout the product mass.

Dynamic Cooling: Monitors and regulates all key storage parameters at multiple points in the cold chamber 24/7, maintaining ideal conditions and extending shelf life by 15%–20% beyond standard storage limits.

Controlled Atmosphere: Optimal gas composition: O₂ 1%–2% and CO₂ 2%–6%, which has been shown to extend storage duration and preserve freshness.

IMPORTANT TIPS
  • Dynamic Cooling is essential for preserving the freshness and extending the storage life of Chinese cabbage.
  • Pre-cool immediately after harvest in low-pressure or high-suction dynamic pre-coolers, and maintain a continuous cold chain during all handling and logistics phases.
  • Store with the outer leaves intact for added protection — remove them shortly before packaging.
  • Remove ethylene using ventilation systems or ethylene absorbers.
  • Install ozone generators to prevent fungal growth and maintain product hygiene.
  • Avoid storing with ethylene-producing products (e.g., apples, pears, tomatoes).
  • Maintain low CO₂ levels to preserve quality and prevent discoloration or tissue breakdown.
