CVF-5000E-10P Vegetable Vacuum Pre-Cooler — 10-Pallet Evaporative-Condenser
CVF-5000E-10P vegetable vacuum pre-cooler handles 5000kg per batch in about 40 minutes with 1-2% weight loss. Evaporative condenser saves water, 294kW+ cooling capacity. For large bases and export produce.
Vacuum pre-cooling makes surface moisture evaporate at reduced pressure, pulling field heat out of produce fast. The CVF-5000E-10P is a 10-pallet large model handling 5000kg per batch, cooling produce to 0–10°C in about 40 minutes with 1–2% weight loss. The evaporative-condenser design saves water and suits large bases and export processing.
Overview
The CVF-5000E-10P is a 10-pallet evaporative-condenser vegetable vacuum pre-cooler for large bases and export-produce processing. The chamber is about 46m³ (L5650×W2750×H3000mm), holding 10 standard pallets. A Bitzer compressor + Leybold pump set deliver 294kW+ cooling capacity. The complete machine includes the mounting frame, vacuum chamber, vacuum pump, and refrigeration system.
Three selling points:
- Large 10-pallet size, 5000kg/batch — covers large bases and export processing
- ~40 minute pre-cooling with 1–2% weight loss
- Evaporative condenser with 294kW+ capacity — stable under heavy load

Product Advantages
1. Large 10-Pallet Size
Fits standard pallets, 5000kg/batch — one machine covers a large base or export line’s daily volume.
2. Rapid Pre-Cooling
~40 minutes from field temperature to 0–10°C — over 10× faster than cold-room natural cooling.
3. Low Weight Loss
1–2% weight loss vs 3–5% in open-air cooling — better appearance and shelf life.
4. High-Capacity Evaporative Condenser
294kW+ cooling capacity with water-saving evaporative condenser — stable under heavy load.

FAQ
Q1: How much per batch? 5000kg per batch (10 pallets). About 40 minutes per cycle; 30–50 tonnes per day.
Q2: What is the weight loss? 1–2%. Lower than open-air cooling — better appearance and shelf life.
Q3: Evaporative vs water-cooled? Evaporative saves water and suits dry regions; water-cooled has slightly higher efficiency but needs a tower. Choose by site water conditions.
Q4: Does it need defrosting? No. Pre-cooling cycles are about 40 minutes — the vapor condenser does not need defrosting.
Q5: What warranty and response time? Full-machine warranty 1 year; major components follow brand standards. Domestic fault response within 24 hours.
