CVF-4000W-10P Fruit and Vegetable Vacuum Precooler (10 Pallets / 4000kg)

CVF-4000W-10P is a 10-pallet vegetable vacuum pre-cooler with a batch capacity of 4,000kg. It cools ambient-harvested produce from 2530°C down to 28°C in about 30 minutes; leafy greens are recommended at 24°C, root vegetables at 48°C. The W suffix indicates a water-cooled shell-and-tube condenser. The vacuum chamber volume is 31.46m³, the cooling capacity is 252.2kW, and the ultimate vacuum is ≤600Pa. It is the large-batch tier of the vegetable vacuum cooler series, suited to production origins with circulating water available.

Where it is used

How cooling works

Vacuum pre-cooling uses the property that water boils at a lower temperature under low pressure: when the chamber pressure drops to ≤600Pa, moisture on the produce surface begins to evaporate, and the latent heat of vaporization comes directly from the produce itself, carrying heat away from the inside. The process has four stages.

Before water vapor enters the vacuum pumps, it is condensed into water by the water catcher (the evaporator of the refrigeration system), so the pump oil does not emulsify. Related process descriptions can be found in the Technical Library.

For models with the same capacity tier and number of pallets, A, W and E differ only in the condensing-end configuration; the vacuum system and water-catching capacity are the same.

Main configuration list

Why choose it

1. A water-cooled solution for 4,000kg per batch. 10 pallet positions and a 31.46m³ chamber; the water-cooled shell-and-tube condenser keeps the condensing temperature stable at 40°C, suitable for origins that already have a cooling tower or circulating water on site.
2. Cooling capacity 252.2kW, operating power 99.7kW. The 73.2kW Hanbell screw compressor drives the complete refrigeration system, completing one batch of pre-cooling in a cycle of about 30 minutes.
3. Parallel rotary-vane pumps directly pull down to ≤600Pa. The target vacuum for vegetable pre-cooling is ≤600Pa, which 2 rotary-vane vacuum pumps in parallel can reach, without adding a water-ring pump or a Roots pump.
4. Complete electrical control and loading/unloading package. LS microcomputer control plus Weinview HMI, with LS temperature detection and Jimai electric system; the chamber interior can be cleaned with a high-pressure water gun.

Installation conditions

• Site: Refrigeration unit external dimensions L2800 × W1900 × H1800mm, vacuum chamber internal dimensions L6500 × W2200 × H2200mm; reserve working and maintenance space accordingly.
• Load-bearing: Equipment weight is about 14,500kg; calculate the foundation load-bearing on this basis, subject to final drawings.
• Power supply: 460V / 60Hz / 3P (source solution configuration); domestic or other voltage systems to be confirmed per order.
• Media: The water-cooled shell-and-tube condenser requires a cooling tower or circulating water system, with makeup water and drainage reserved.
• Exhaust air: Heat rejection is concentrated when the refrigeration unit runs; the installation position must keep air intake unobstructed.

Warranty and after-sales

One-year warranty for the complete machine; solution within 2 hours, on-site arrival within 24 hours, fault clearance within 72 hours; one free on-site visit per year; lifetime technical support.

FAQ

What does the W suffix mean?

W stands for water-cooled, i.e. equipped with a shell-and-tube condenser, requiring a cooling tower or circulating water system. The same capacity tier also has A (air-cooled) and E (evaporative condenser): choose A when no water is available on site, and choose E when you want a stable condensing temperature with only a small amount of makeup water.

With 4,000kg per batch, how much can be processed per day?

Each cycle is about 30 minutes; actual daily throughput depends on loading and unloading time, produce category and loading density. After confirming your daily harvest volume and site rhythm, we can calculate the number of batches per day according to the feeding method.

Why 10 pallet positions?

Pallet positions are arranged according to standard pallet dimensions; 10 positions correspond to a loading capacity of 4,000kg per batch. If your pallet specifications or stacking height differ, the loading capacity will change, and the model selection needs to be checked against the actual pallets and chamber dimensions.

What on-site support does a water-cooled model require?

It requires a cooling tower or circulating water system, as well as power distribution for makeup water, drainage and the circulating water pump. The advantage of water cooling is that the condensing temperature is stable near the design value of 40°C, unaffected by summer ambient air temperature.

What is the power supply?

The source solution configuration is 460V / 60Hz / 3P. Voltage and frequency systems differ by country and region; for export or domestic projects, the corresponding electrical configuration is issued after order confirmation.
