CVF-4000E-8P Vegetable Vacuum Pre-Cooler — 8-Pallet Evaporative-Condenser
CVF-4000E-8P vegetable vacuum pre-cooler handles 4000kg per batch in 30-40 minutes with 1-2% weight loss. Evaporative condenser saves water, 247kW+ 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-4000E-8P is an 8-pallet standard model handling 4000kg per batch, cooling leafy vegetables to 0–10°C in 30–40 minutes with 1–2% weight loss. The evaporative-condenser design saves water and suits large bases and export processing.
Overview
The CVF-4000E-8P is an 8-pallet evaporative-condenser vegetable vacuum pre-cooler for large bases and export-produce processing. The chamber is about 22–39m³ (L5200×W1940×H2200mm or per drawings), holding 8 standard pallets. A Bitzer compressor + quad vacuum pumps deliver 247kW+ cooling capacity. The complete machine includes the mounting frame, vacuum chamber, vacuum pump, and refrigeration system.
Three selling points:
- Standard 8-pallet size, 4000kg/batch — covers large bases and export processing
- 30–40 minute pre-cooling with 1–2% weight loss
- Evaporative-condenser design — water-saving, suited to hot regions

Product Advantages
1. Standard 8-Pallet Size
Fits standard pallets, 4000kg/batch — one machine covers a large base or export line’s daily volume.
2. Rapid Pre-Cooling
30–40 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 for export produce.
4. Water-Saving Evaporative Condenser
Uses less water than water-cooled systems — suited to hot, dry growing regions with lower running cost.

FAQ
Q1: How much per batch? 4000kg per batch (8 pallets). Leafy vegetables pre-cool in 30–40 minutes; 20–40 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 30–40 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.
