CVF-2000E-4P Vegetable Vacuum Cooler

Product Overview

The CVF-2000E-4P is Yuanxian's workhorse medium-to-large vegetable vacuum cooler with an evaporative condenser design. The 2000 kg batch capacity makes it the first-choice model for large vegetable farms, Hong Kong-bound produce, mushroom processing bases, and export-oriented cold chain facilities.

Typical Applications:

• Large-scale leafy green farms (lettuce, spinach, choi sum, broccoli)
• Fresh-cut vegetable processing plants — raw material pre-cooling
• Mushroom farms — rapid post-harvest cooling
• Fruit pre-cooling before cold storage transport
• Export-grade produce pre-cooling for sea/air freight

The evaporative condenser keeps it running in areas with limited water supply or restricted cooling tower space — one less maintenance point than a traditional water-cooled chiller setup.

Why Choose the CVF-2000E-4P?

vs. Cold Room Cooling

vs. Competing Models

Most Chinese 2000 kg-class vegetable vacuum coolers use domestic dual-stage or water-ring pumps. The ultimate vacuum drifts after 6 months — and when the vacuum degrades, cooling time stretches. CVF-2000's Leybold pump keeps the ≤600 Pa vacuum stable for a year of continuous operation.

The Hanbell screw compressor delivers 15–20% better COP over piston compressors at partial load. Over a 300-day working year, that's a real difference on the monthly electricity bill.

FAQ

Q1: What's the actual daily throughput?
A1: With a 25-minute cycle (including loading/unloading), 2 batches per hour, 16 hours per day, theoretical throughput is ~64 tonnes of leafy greens. Real-world output ranges 40–55 tonnes depending on product type and operator efficiency.

Q2: How does the evaporative condenser differ from water-cooled?
A2: Evaporative condensers use water evaporation to reject heat — 15–30% more energy-efficient than air-cooled, and don't need a cooling tower. Best for sites with limited water supply, restricted installation space, or hard water prone to scaling. Requires good ventilation and periodic fin cleaning.

Q3: Is CE certification available for export?
A3: Yes. All Yuanxian machines carry CE certification. The CVF-2000 can be configured for 380V/50Hz or 460V/60Hz to match destination country power standards.

Q4: What's the spare parts lead time?
A4: Common parts (pressure switches, filters, seals) held in stock — shipped within 48 hours domestically. Hanbell and Leybold parts supplied directly by the manufacturers. Recommend quarterly stocking of consumables (refrigeration oil, filter elements).

Q5: Can this handle mushrooms and fruits too?
A5: Yes. The vacuum level and cooling rate are programmable. Mushrooms (button, shiitake, oyster) require slightly slower pull-down to prevent cap damage. For soft fruits (berries, cherries), set a higher final temperature target. The PLC stores multiple preset programs.
