Product overview
The CVF-2000E-4P is Yuanxian's mid-to-large vegetable vacuum pre-cooler with an evaporative condenser design. A batch capacity of 2,000 kg makes it the model of choice for large vegetable farms, Hong Kong supply vegetables, mushroom processing bases and export-oriented cold chain facilities.
Typical applications: large-scale leafy green farms, fresh-cut vegetable plants, mushroom farms, fruit pre-cooling, and pre-cooling of export-grade produce for sea or air freight.
Key performance: 15–30 minute cooling time, ultimate vacuum level โค600 Pa, moisture loss โค2%, final product temperature adjustable from 0 to 10ยฐC.

Why choose the CVF-2000E-4P?
Versus cold room cooling: 20–30 minutes vs 8–12 hours, moisture loss <2% vs 5–10%, and a temperature uniformity of ยฑ1ยฐC vs a 5–10ยฐC gradient.
The Hanbell screw compressor saves 15–20% energy against a reciprocating compressor at part load. A Leybold vacuum pump holds โค600 Pa stable operation for a year — while domestic pumps lose performance within 6 months.
FAQ
Q: What is the actual daily throughput?
A: Based on a 25-minute cycle, 2 batches per hour and 16 hours of operation per day — about 64 tonnes in theory. In practice: 40–55 tonnes, depending on the product and on operating efficiency.
Q: How does an evaporative condenser differ from a water-cooled one?
A: An evaporative condenser saves 15–30% energy compared with air-cooled and needs no cooling tower. It is best suited to sites with a limited water supply.
Q: Is CE certification available?
A: Yes. All Yuanxian machines carry CE certification. They can be configured for 380V/50Hz or 460V/60Hz.
Q: Can it handle mushrooms and fruit?
A: Yes. The vacuum level and the cooling rate are programmable. The PLC stores presets for several different products.
