CVF-1000A-2P Fruit and Vegetable Vacuum Precooler — 2-Pallet Air-Cooled, 800–1000 kg/Batch

CVF-1000A-2P is a Yuanxian 2-pallet air-cooled vegetable vacuum pre-cooler: 8001000kg per batch, cools ambient produce (2530°C) to 110°C in 1530 minutes, ultimate vacuum ≤600Pa, uses an air-cooled condenser, no cooling tower required.

Where it is used

CVF-1000A-2P is designed for small to medium batch post-harvest pre-cooling, especially at production sites where water supply is inconvenient or pipes freeze in winter.

How cooling works

Water boils at 100°C under normal pressure. When the pressure inside the chamber is drawn below 600Pa, the boiling point of water drops to near 0°C — moisture on the surface of the produce begins to evaporate, and each 1kg of water evaporated carries away about 2500kJ of heat. The heat is drawn directly from the produce itself, so cooling proceeds from the inside out and is uniform throughout the chamber.

Why choose CVF-1000A-2P

An order of magnitude faster than a cold room 800kg of leafy vegetables takes 610 hours to cool to 5°C in a cold room; a vacuum pre-cooler does it in 1530 minutes.

Uniform throughout the chamber, no cold spots Vacuum pre-cooling removes heat through moisture evaporation; every item in the chamber reaches the same temperature, without the cold-room problem of “surface cold, core still warm”.

Air-cooled model, no cooling tower needed No circulating water, no cooling tower, and no risk of pipes freezing and bursting in winter; installation and routine maintenance are simpler.

Mature component selection Bitzer compressors and Leybold SV300 vacuum pumps have well-established service networks at home and abroad; routine maintenance is mainly oil and filter changes.

FAQ

How much electricity does one cycle consume? Running power at full load is 39.9kW. Processing 800kg of vegetables in a single 20-minute cycle consumes roughly 13~14kWh; actual consumption depends on product moisture content and starting temperature.

Can it hold standard pallets? The chamber is 2600×1400×2200mm and holds 2 standard pallets (1200×800mm). Custom sizes are available.

Does it need an external chiller? No. This model has a built-in air-cooled condenser that shares the compressor circuit with the main refrigeration system.

What is the approximate weight loss? Usually 1~3%, depending on the surface-area-to-volume ratio of the product and the starting temperature. For moisture-loss-sensitive products such as shiitake, the final pressure setting can be adjusted to reduce weight loss.

What is the lead time? 2~3 weeks for standard configuration, depending on the production schedule.
