CVF-1000E-2P Vegetable Vacuum Cooler: 1,000 kg Twin-Pallet

Product overview

Yuanxian CVF-1000E-2P vegetable vacuum pre-cooler (2-pallet standard model) is a batch rapid cooling system designed for farms, cooperatives, cold chain logistics centres and produce export companies. Fitted with German BITZER compressors and German Leybold vacuum pumps, and CE / CSA certified.

Target applications: leafy greens (lettuce, spinach, pak choi), mushrooms (shiitake, button, oyster), fresh cut flowers (roses, lilies, carnations), fruit (strawberries, blueberries, lychee) and first-step pre-cooling for the export cold chain.

Key performance: cooling in 20–30 minutes (against 6–12 hours in a cold room), capacity 800–1,000 kg per batch (up to 8–12 tonnes per day), moisture loss ≤2%, final temperature 0–10°C (adjustable).

Core advantages

1. Extremely fast cooling — 20 minutes against 12 hours in a cold room. 10–20 times faster than a conventional cold room.
2. Uniform temperature — uniform cooling from core to surface, with a temperature difference within the batch of ≤1°C.
3. Low weight loss — moisture loss ≤2%, against 3–5% for forced air cooling.
4. Longer shelf life — leafy greens from 3 days to 7–10 days.
5. Hygiene and safety — the low-oxygen vacuum environment suppresses bacterial growth.
6. Fully automatic operation — one-button start, unattended running, remote monitoring.
7. International certification — CE and CSA certified.

How it works

1. Evacuation — the vacuum pump reduces chamber pressure to ≤600 Pa
2. Moisture evaporation — at 600 Pa the boiling point of water falls to about 0°C; surface moisture vaporises instantly
3. Heat absorption — evaporation consumes latent heat (about 2,500 kJ/kg), drawn directly from the produce
4. Temperature drop — continuous evaporation rapidly lowers the product temperature
5. Automatic shutdown — the system stops automatically when the target temperature or vacuum level is reached

FAQ

Q: What is the daily throughput?
A: 8–12 tonnes per day, 2–3 cycles per hour, running 8–10 hours per day.

Q: Which product types benefit most?
A: Products with high moisture content and an open surface: leafy greens, mushrooms, berries, herbs and fresh cut flowers.

Q: How does a vacuum pre-cooler compare with a cold room?
A: Vacuum pre-cooling is 10–20 times faster than a cold room, with less moisture 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 pre-cooling. To cool hot food (from 90°C down to 10°C), see Yuanxian's food vacuum cooling range.

Q: What are the installation requirements?
A: A 380V/50Hz/3P power supply (150 A breaker), a cooling water supply, and at least 6 m × 3 m of installation space.
