Export flowers from Kunming require rapid removal of field heat before air freight. Every extra hour of delay reduces vase life by 1–2 days. Conventional cold storage took 6+ hours, and shipping loss rates were 12%.
The Solution
CVF-1000A-3P vacuum pre-cooler installed at the flower export hub.
Results
| Parameter | Value |
|---|---|
| Core temp drop | 26°C → 4°C in 18 minutes |
| Vase life | 8–10 days (vs 4–5 days without pre-cooling) |
| Shipping loss rate | reduced from 12% to 3% |
| Industry adoption | 75% of Kunming flower exporters now use vacuum pre-cooling |
Key Insight
Kunming’s flower industry has made vacuum pre-cooling a de facto standard for export-grade flowers. The rapid temperature pull-down combined with surface moisture removal prevents botrytis and extends vase life by 2×.
