China cold storage solution provider
Kiwifruit is one of the most temperature-sensitive fruits in global trade. After harvest, it continues to respire—and without precise cold chain control, it softens, loses acidity, and becomes unmarketable in under 2 weeks.
But with a professionally designed cold room, you can:
✔️ Extend shelf life to 50–60 days (standard chill)
✔️ Or 100–120+ days with Controlled Atmosphere (CA)
✔️ Maintain firmness, flavor, and export-grade quality
✔️ Ship by sea—not air—to Europe, the Gulf, or North America
So how much does a 100-ton kiwifruit storage facility really cost—and how much space do you actually need?
📦 Updated: Realistic Storage Capacity (Industry Standard)
For a 100-Ton Facility:
| Parameter | Value |
|---|---|
| Required usable volume | 500 – 550 m³ |
| Typical floor area (4m height) | 125 – 140 m² |
| Pallet capacity | 220 – 260 pallets (400–450 kg each) |
| Carton equivalent | ~22,000 – 28,000 boxes (depending on size) |
✅ This is enough to store 2–3 full 40ft refrigerated containers—perfect for batch harvesting and staggered exports.
💰 Total Investment: Standard vs. Controlled Atmosphere (CA)
| Option | Temp & Atmosphere | Shelf Life | Total Turnkey Cost (USD) |
|---|---|---|---|
| Standard Chilled Room | 0°C ±0.5°C Normal air, 90–95% RH |
50–60 days | $38,000 – $48,000 |
| Controlled Atmosphere (CA) Room | 0°C ±0.5°C O₂: 2–3% / CO₂: 4–5% + Ethylene scrubber |
100–120+ days | $72,000 – $95,000 |
✅ Both include:
- 120mm PU insulated panels (high-density, food-grade)
- Emerson Copeland scroll compressor (reliable, low maintenance)
- Ceiling-mounted air cooler with precise humidity control
- Digital monitoring with cloud alerts (SMS/email)
- Full installation & commissioning (~10–12 days on-site)
💡 Why CA costs more: Airtight doors, O₂/N₂ generator or membrane system, CO₂ scrubbers, and continuous gas monitoring.
Project Timeline
- Equipment lead time: 12–15 days
- On-site installation: 10–12 days
- Ready for fruit: Within 4 weeks of order—ideal for pre-harvest planning
🌍 Real Exporter Insight: CA Pays Off in Off-Season Markets
A kiwifruit cooperative in central Italy built a 520m³ CA room (100-ton capacity):
- Total Investment: $84,000 USD
- Stored: 100 tons of Hayward kiwifruit (harvested October)
- Sold: February–April to German & Dutch supermarkets
- Result:
- Achieved €1.85/kg in March vs. €0.78/kg at harvest
- ROI in 11 months
🔑 Critical Storage Conditions for Kiwifruit
- Temperature: 0°C (never below –0.5°C → chilling injury)
- Relative Humidity: 90–95% (prevents weight loss & shriveling)
- Ethylene: Must be <0.1 ppm—kiwifruit is extremely sensitive
- Pre-cooling: Fruit must reach 0°C within 12–24 hours of picking
❌ Overcrowding = poor airflow = hot spots = uneven ripening
✅ Proper spacing (5–5.5 m³/ton) = uniform quality across all pallets
