In the model code, A stands for air-cooled condenser, L stands for low-temperature type.
Where it is used
| Application | Typical materials | Description |
|---|---|---|
| Cooked food and braised product processing | Braised beef, braised duck, roast chicken, pig trotters | Whole batch goes into the chamber after cooking, 200 kg in one load, stable batch rhythm |
| Central kitchen / group catering | Braised pork, stewed dishes, side dishes | Cooling no longer blocks the portioning line, multiple batches per shift |
| Prepared dish production lines | Prepared meat products, toppings, soup dishes | Shortens work-in-process time, reduces waiting-for-cooling occupancy |
| Meat and poultry processing | Roast chicken, roast duck, sausage, ham | Core and surface cool simultaneously, no cold-outside-hot-inside |
| Bakery plants | Toast, bread, mooncakes | Baked goods have low moisture content (15~45%), less moisture loss, crust less prone to cracking |
How cooling works
Vacuum cooling uses two stages, with two vacuum pumps dividing the work, not the same pump from start to finish.
| Step | Cooling range | Working parts | Description |
|---|---|---|---|
| 1. High-humidity stage rough pumping | 90°C → about 50°C | Water ring pump works alone | Water ring pump withstands high temperature and high humidity, circulating water also acts as first-stage water capture |
| 2. Low-temperature stage fine pumping | About 50°C → 0~8°C | Rotary vane pump + water catcher | Refrigeration system starts, water catcher condenses water vapor, rotary vane pump draws chamber pressure down to ≤600 Pa |
| 3. Break vacuum and unload | Target temperature reached | Stop and break vacuum | After pressure equalizes, open door and remove materials, proceed to next batch |
The water catcher is a prerequisite for this process. Without it, water vapor enters the rotary vane pump, the pump oil emulsifies, and vacuum level cannot be maintained. Therefore all Yuanxian vacuum coolers come standard with a refrigeration system, and the water catcher evaporation temperature is uniformly -10~-5°C.

Why choose it
- Two pumps each handle one stage. The water ring pump tackles the high-humidity stage from 90°C→50°C first, the rotary vane pump only does low-temperature fine pumping, pump oil is less prone to emulsification, oil change intervals and vacuum stability are more controllable.
- The 1.44 m³ chamber with L1000×W800×H1800 mm internal cavity allows standard tray carts to roll in and out whole, no need to unload materials for loading and unloading.
- Air-cooled, easy floor conditions. Workshops without cooling towers, with unstable circulating water quality, or worried about pipe freezing in winter can install the machine directly.
- Refrigeration system comes standard. The water catcher condenses water vapor at -10~-5°C, water vapor cannot reach the pumps, chamber pressure stays stable at ≤600 Pa, results are consistent between batches.
FAQ
How much can CVF-200A-L hold per batch, and how long does it take?
Batch load 200 kg, cycle time 20~30 minutes, including loading, vacuum pumping, cooling and vacuum breaking for unloading. Time depends on material thickness, moisture content and target temperature; the greater the thickness variation within a batch, the closer the core temperature reaching target time is to the upper limit.
What discharge temperature can be reached?
The low-temperature (L) type discharge temperature is 0~8°C, settable within the temperature control range. The endpoint can be set near 8°C, leaving the remaining temperature difference to the cold storage for equalization, with less moisture loss.
What are the chamber internal dimensions, can tray carts be used?
Vacuum chamber internal dimensions L1000×W800×H1800 mm, volume 1.44 m³. Standard tray carts can be pushed in whole; specific shelf layout and cart dimensions are confirmed per order before signing.
How are the vacuum pump and water catcher configured?
The vacuum side is water ring pump + rotary vane pump two-stage: the water ring pump withstands high temperature and high humidity, responsible for rough pumping from 90°C→50°C; the rotary vane pump does fine pumping at the rear end of the water catcher, drawing chamber pressure down to ≤600 Pa. The water catcher has a heat exchange area of 8.5 m², Yuanxian self-made hot-dip galvanized iron pipe, evaporation temperature -10~-5°C.
What is the difference from CVF-200W-L?
The two models have the same load, chamber volume, cooling capacity and cycle time; the difference is the condenser: A is air-cooled, W is water-cooled. Choose the water-cooled model if the workshop has a cooling tower and circulating water system, choose the air-cooled model if there are no water conditions. For more capacity tiers see the food vacuum cooler series page.
