Product Overview
The Yuanxian CVF-1000E-2P Vegetable Vacuum Cooler (2-pallet standard model) is a batch rapid-cooling system designed for farms, cooperatives, cold-chain logistics centers, and produce export companies. Powered by a BITZER (Germany) compressor and Leybold (Germany) vacuum pump, it is CE/CSA certified and deployed in 30+ countries.
Target Applications: Leafy greens (lettuce, spinach, bok choy), mushrooms (shiitake, button, oyster), fresh-cut flowers (roses, lilies, carnations), fruits (strawberries, blueberries, lychee), and export cold-chain first-step precooling.
Key Performance: Cooling speed 20–30 min vs 6–12 hours in cold rooms, capacity 800–1,000 kg/batch (up to 8–12 tons/day), water loss ≤2%, final temperature 0–10°C (adjustable).

Key Advantages
- Ultra-Fast Cooling — 20 min vs 12 hours in cold storage. 10–20× faster than conventional cold rooms.
- Uniform Temperature — Core-to-surface even cooling with ≤1°C variance across batch.
- Low Weight Loss — ≤2% water loss vs 3–5% for forced-air cooling.
- Extended Shelf Life — Leafy greens from 3 days to 7–10 days.
- Hygienic — Low-oxygen vacuum environment suppresses bacterial growth.
- Fully Automated — One-button start, unattended operation, remote monitoring.
- International Certification — CE and CSA certified, deployed in 30+ markets.

How It Works
- Evacuation — Vacuum pump reduces chamber pressure to ≤600 Pa
- Water evaporation — At 600 Pa, water's boiling point drops to ~0°C; surface moisture vaporizes instantly
- Heat absorption — Evaporation consumes latent heat (~2,500 kJ/kg), drawn directly from the produce
- Temperature drop — Continuous evaporation rapidly lowers product temperature
- Auto shutoff — System stops automatically when target temperature or vacuum level is reached
FAQ
Q: What is the daily capacity?
A: 8–12 tons per day with 2–3 cycles per hour and 8–10 hours of daily operation.
Q: Which produce types benefit most?
A: High-moisture produce with open surface area: leafy greens, mushrooms, berries, herbs, and cut flowers.
Q: Vacuum precooler vs. cold room?
A: Vacuum precooling is 10–20× faster with lower water loss and more uniform cooling. The two methods complement each other in a complete cold chain.
Q: Can the CVF-1000 cool cooked food?
A: The CVF-1000 is designed for fruit and vegetable precooling. For hot food cooling (90°C to 10°C), see Yuanxian's Food Vacuum Cooler series.
Q: What are the installation requirements?
A: Requires 380V/50Hz/3P power (150A breaker), cooling water supply, and minimum 6m × 3m installation footprint.
