CVF-1000W-N Food Vacuum Cooler | 1000kg Batch Commercial Food Vacuum Cooling

From 90°C to 28°C in 2530 minutes. Bitzer screw compressor + Leybold rotary vane pump — German core components. 900~1000kg per batch for central kitchens, cooked meat factories, prepared meal lines, and meat processing plants. The refrigeration system provides cooling for the vapor trap condenser — the vacuum pump only handles non-condensable gases. This is the engineering foundation for tens of thousands of hours of reliable operation.

Quick Specs

How It Works

Food vacuum cooling operates on the evaporative cooling under reduced pressure principle. When chamber pressure drops below 600 Pa, moisture on and within the food surface begins to boil at low temperature, absorbing latent heat. Heat releases uniformly from core to surface — unlike blast chilling which relies on thermal conduction and often causes surface hardening before the center is cold.

The critical difference from vegetable vacuum precooling: food vacuum coolers handle hot product at 80~90°C (cooked meat, bakery, prepared meals). This requires a three-stage vacuum curve to control cooling rate and water loss:

• Stage 1 (Rapid Pressure Drop): Draw down to medium vacuum. Surface moisture evaporates fastest here — most water loss happens in this stage.
• Stage 2 (Controlled Evaporation): Maintain chamber pressure via an air-bleed valve. This lets the internal temperature catch up to the surface, preventing “dry outside, hot inside.”
• Stage 3 (Final Cooling): Drop to target pressure. Product cools uniformly from center to surface to the final temperature.

The refrigeration system’s role:

• The vapor trap (cold catcher) maintains a -10 to -15°C surface
• Water vapor condenses on the trap surface, releasing latent heat
• Refrigerant circulates the heat to an outdoor condenser
• The vacuum pump only removes non-condensable gases

Without a refrigeration system, the vacuum pump would pull a water vapor / gas mixture and suffer oil emulsification within days. This isn’t optional — every Yuanxian food vacuum cooler includes a complete refrigeration system.

FAQ

Q1: What’s the difference from a vegetable vacuum precooler? CVF-1000 is a food vacuum cooler designed for 80~90°C inlet temperature (cooked food, bakery). It uses a three-stage vacuum curve to manage cooling rate and water loss. Vegetable precoolers handle ambient temperature product (2535°C) with a different cooling curve. They are not interchangeable.

Q2: What is the typical water loss? Cooked meat: 1.82.5%. Bakery: 35%. Controlled via multi-stage vacuum curve. Recommended strategy: cool to 15°C then finish in a cold room — reduces water loss significantly.

Q3: Can I use it without a refrigeration system? No. The vapor trap needs refrigeration to condense water vapor. Without it, the vacuum pump pulls a vapor-gas mixture and emulsifies within days. Every Yuanxian cooler has a complete refrigeration system.

Q4: How many batches per day? At 25~30 min per cycle (including loading/unloading), approximately 2 batches per hour. In an 8-hour shift, ~16 batches — up to 16 tons/day throughput.

Q5: Can I run on 220V? Standard is 3P-380V-50Hz. 220V/60Hz or other voltages can be customized with transformer adjustments.
