California: 12-Pallet High-Volume Vacuum Pre-Cooling — CVF-8500-12P
A California processor handles 8+ tons of leafy greens per batch with a CVF-8500-12P vacuum pre-cooler — 12 pallets, dual compressors, running reliably since 2014.
The Challenge
A large California processor needed to push 8+ tons of leafy greens and mixed produce per batch — more than any single-unit machine in its class at the time. Electrical standard was US 440V/60Hz. The client required a single machine capable of processing an entire harvest shift in one batch.
The Solution
We delivered a CVF-8500-12P (12-pallet) vacuum pre-cooler with a heavy-duty configuration:
| Parameter | Value |
|---|---|
| Model | CVF-8500-12P (12 pallet) |
| Product | Leafy greens / Mixed produce |
| Capacity | ~8,400 kg per batch |
| Cooling time | 25–35 min |
| Compressors | Dual BITZER CSH8563 (117.2 kW each) |
| Vacuum pumps | 4× V0630B (18.5 kW) |
| Feed system | Glycol conveyor |
| Power | 440V/60Hz |
| Status | ✅ Running since 2014 |
The 60Hz power actually increased compressor capacity by approximately 20% vs standard 50Hz rating.
Results
- Single machine processes an entire harvest shift in one cycle
- Over a decade of continuous operation without major downtime
- Multi-compressor + multi-pump configuration provides built-in redundancy
Key Takeaway
When throughput exceeds 5 tons per batch, a multi-compressor, multi-pump configuration is recommended. The per-unit redundancy also improves overall uptime.
