CVF-1000 Vacuum Pre-cooler – 2-Pallet, 800~1000kg/batch, 15~30 min to 1~10°C
Vegetable Vacuum cooling works by lowering the chamber pressure until surface moisture on the produce evaporates, carrying heat away. The CVF-1000 is Yuanxian’s standard 2-pallet model: 800
1000kg per batch, 1530 min cycle time, ≤600Pa ultimate vacuum, 1~10°C final product temperature.
What is it for?
The CVF-1000 is built for small-to-medium batch vacuum pre-cooling of fresh produce.
| Application | Typical Users | Batch Size |
|---|---|---|
| Leafy greens (lettuce, spinach, bok choy) | Export vegetable farms, cooperatives | 800~1000kg |
| Mushrooms (shiitake, button, oyster) | Mushroom growers | 800~1000kg |
| Cut flowers (roses, lilies, carnations) | Flower exporters | 800~1000kg |
| Soft fruits (strawberries, blueberries, cherries) | Fruit packhouses | 800~1000kg |
How it Works
Water boils at 100°C at standard atmospheric pressure. When chamber pressure drops below 600Pa, water boils at near 0°C — which means the water on the surface of your produce evaporates, and each kilogram of vapour carries away about 2500 kJ of heat from the produce itself.
| Step | Component | Function |
|---|---|---|
| ① Load | Hydraulic door | Hydraulic operation for easy cart loading |
| ② Evacuate | Leybold rotary vane pump (5.5kW) | Pulls chamber from atmosphere to ≤600Pa |
| ③ Cool | Chamber (8m³) | Surface moisture evaporates → produce cools from inside out |
| ④ Trap vapour | Vapour condenser (Yuanxian design) | Condenses water vapour, protects vacuum pump |
| ⑤ Maintain cold | Bitzer compressor (30.7kW) | Keeps vapour condenser cold, assists chamber cooling |
| ⑥ Stop | LS PLC control | Auto-stops when set temperature is reached |

Why the CVF-1000E-2P?
10x faster than cold room
A cold room takes 610 hours for 800kg of leafy greens. The CVF-1000 finishes in 1530 minutes.
Uniform cooling, no hot spots Vacuum pre-cooling removes heat through moisture evaporation — every item in the chamber reaches the same temperature. No cold-room problem where the surface is cold but the core stays warm.
Export-grade performance Strict cold chain requirements for export markets (e.g. ≤4°C core temp for long-haul transport). The CVF-1000 delivers consistent 1~10°C final temperature.
Proven components Bitzer compressors are used globally with wide service networks. Leybold SV300 pumps are industry-standard for medium vacuum. Routine maintenance is limited to oil and filter changes.
FAQ
What is the hourly power consumption? Full-load draw is 39.9kW. A single 20-minute cycle processing 800kg of vegetables consumes roughly 13~14 kWh. Actual consumption depends on product moisture content and starting temperature.
Can it fit standard pallet sizes? Internal chamber is 2600×1400×2200mm — fits 2 standard EU pallets (1200×800mm). Custom chamber dimensions are available on request.
Does it need an external chiller? No. The vapour condenser runs on the integrated Bitzer compressor circuit. For the condenser, choose air-cooled or water-cooled (water-cooled requires a cooling tower).
What about water loss on high-value crops? Weight loss is typically 1~3%, depending on surface-area-to-volume ratio and starting temperature. For mushrooms or other moisture-sensitive items, the final vacuum setpoint can be adjusted to reduce moisture loss.
Lead time? Standard configuration: 2~3 weeks (subject to production schedule).
