مزود حلول التخزين البارد في الصين
مع اقتراب موسم الحصاد, يسأل العديد من المزارعين:
- "كيف يمكنني تمديد نضارة الفواكه والخضروات?”
- “Can I store apples, الكيوي, or pears until next year and still keep them fresh?”
If you’re facing the same challenge, then Controlled Atmosphere (كاليفورنيا) cold storage may be the solution you’re looking for.

What Is Controlled Atmosphere (كاليفورنيا) Cold Storage?
CA storage, also known as modified atmosphere storage, is one of the most advanced post-harvest preservation methods globally.
Unlike traditional refrigeration, CA storage precisely regulates:
Temperature
رطوبة
Oxygen (O₂)
Carbon dioxide (CO₂)
Ethylene gas levels
By adjusting these environmental parameters, the respiration and aging processes of produce are slowed down, significantly extending both storage life and shelf life — while maintaining freshness, color, firmness, and flavor.
Why Choose Controlled Atmosphere Over Standard Cold Storage?
Core Advantages vs Conventional Cold Storage
| Parameter | Conventional Cold Storage | CA Storage | Improvement |
|---|---|---|---|
| Storage Duration | 3-6 months | 9-12 months | +200% |
| Post-Storage Shelf Life | 7-10 days | 28-35 days | +300% |
| Fruit Firmness Retention | 65% | 92% | +41% |
| Weight Loss | 8-12% | 2-4% | -70% |

How CA Technology Works
1. Triple-Action Preservation
- O₂ Reduction: 1-5% (vs 21% ambient) → slows respiration
- CO₂ Enrichment: 1-10% → inhibits microbial growth
- Ethylene Scrubbing: <0.1 ppm → delays ripening
2. Precision Environmental Control
- Temperature: -0.5°C to 15°C (±0.3°C)
- رطوبة: 90-95% RH (±2%)
- Gas Composition: Laser sensors maintain ±0.2% accuracy
Industry-Proven Applications
| Produce | Optimal CA Parameters | Max Storage |
|---|---|---|
| Apples | 1.5% O₂, 1% CO₂ @ 0.5°C | 12 months |
| Kiwifruit | 2% O₂, 5% CO₂ @ 0°C | 10 months |
| Broccoli | 1% O₂, 10% CO₂ @ 0°C | 8 weeks |
| Avocados | 2% O₂, 5% CO₂ @ 5°C | 6 weeks |
