CVF-300W-L Food Vacuum Rapid Cooler | 300kg/batch · 25–35 min · 90℃→0–8℃

CVF-300W-L is the 300 kg water-cooled model in the Vacuum-Fresh rapid cooling line. It loads 300 kg of hot food per batch and cools from a 8090℃ out-of-pot temperature down to 08℃ in 25~35 minutes; the vacuum chamber volume is 3.2 m³, the cooling capacity is 60 kW, and the installed power is 55 kW. In the model code, W indicates a water-cooled condenser and L indicates the low-temperature type.

Where it is used

How cooling works

Rapid cooling uses two stages, with two vacuum pumps dividing the work; the same pump is not used from start to finish.

The water catcher is a prerequisite for this process. Without it, water vapor would enter the rotary vane pump, the pump oil would emulsify, and the vacuum level could not be maintained. Therefore all Vacuum-Fresh rapid coolers are equipped with a refrigeration system as standard, and the water catcher evaporation temperature is uniformly -10~-5℃.

For the capacity tiers and suffix meanings of the entire rapid cooling line, see the product series page.

Main configuration list

Why choose it

1. The two pumps each handle one stage. The water ring pump first handles the high-humidity stage from 90℃ to 50℃, and the rotary vane pump only performs low-temperature fine pumping, so the pump oil is less likely to emulsify, and the oil change interval and vacuum stability are more controllable.
2. 3.2 m³ chamber, 300 kg per chamber. The main tier for medium-sized cooked food plants and central kitchens; chambers can be opened continuously in a single shift, with no waiting for cooling from out-of-pot to warehousing.
3. Water-cooled model, with sufficient margin in hot seasons. The condenser is water-cooled; when the workshop already has a cooling tower and circulating water system, heat dissipation is more stable, making it suitable for southern summers and continuous production conditions.
4. Refrigeration system included as standard. The water catcher condenses water vapor at -10~-5℃, so water vapor cannot enter the pump, the chamber pressure stays stable at ≤600 Pa, and results are consistent between batches.

FAQ

How much can CVF-300W-L hold per batch, and how long does it take?

The batch load is 300 kg, and the cycle time is 25~35 minutes, including loading, vacuum pumping, cooling and vacuum breaking for discharge. The time depends on material thickness, moisture content and target temperature; braised products with broth have greater evaporation, so the time will be closer to the upper limit.

What discharge temperature can be reached?

The discharge temperature of the low-temperature (L) type is 0~8℃, settable within the temperature control range. If there is a subsequent cold chain portioning process, the endpoint can be set near 8℃, and the remaining temperature difference can be balanced by the cold storage.

What needs to be provided on site for the water-cooled model?

The site needs to provide circulating cooling water and a cooling tower; the cooling water flow rate is configured according to order requirements, and the inlet water temperature is recommended to be controlled within 32℃; in addition, a three-phase power supply and clean, dry compressed air are required for the pneumatic door and valves. Specific pipe diameters, flow rates and pressures are confirmed item by item during the solution stage.

How are the vacuum pump and water catcher matched?

The vacuum side is two-stage: water ring pump + rotary vane pump. The water ring pump withstands high temperature and high humidity and handles rough pumping from 90℃ to 50℃; the Leybold SV300B rotary vane pump performs fine pumping downstream of the water catcher, drawing the chamber pressure down to ≤600 Pa. The water catcher evaporation temperature is -10~-5℃; it first condenses water vapor, and then the refrigerant carries the heat out of the chamber.

How to choose between it and CVF-500W-L?

CVF-500W-L has a batch load of 500 kg, a vacuum chamber volume of 6.0 m³, a cycle time of 3040 minutes, a discharge temperature of 410℃, a cooling capacity of 95 kW, and an installed power of 75 kW. For a daily processing capacity of around 1 ton, choose CVF-300W-L; for more than two tons, consider the 500 kg tier. For more capacity tiers, see the food vacuum cooler series page.
