CVF-500A-1P_Vacuum_cooler

CVF-500 Fruit & Vegetable Vegetable Vacuum Cooler | 500kg/batch, Cool from Field to 2~5°C in 20 min, Water Loss <2%

The CVF-500A-1P fruit & vegetable [vegetable vacuum cooler](https://www.vacuum-fresh.com/products/vacuum-precooler/) is designed for small-to-medium farms, cooperatives, and distribution centers.It processes 500kg of produce per cycle, cooling from field temperature (25~35°C) to 2~5°C in just 20~30 minutes, with water loss controlled under 2%. This is 5~10x faster than traditional cold room pre-cooling, extending shelf life by 3~7 days. Built with a Copeland ZB scroll compressor, Busch vacuum pump, and LS industrial control system, it achieves ultimate vacuum ≤600Pa. CE/CSA/BV certified, 380V/50Hz/3P power, 29.24kW total power draw. Ideal for leafy greens, mushrooms, berries, cut flowers, and herbs — the essential first link in the cold chain.

DETAIL

Product Overview

The CVF-500A-1P is Yuanxian's standard 1-pallet vegetable vegetable vacuum cooler, operating on the principle of vacuum flash evaporation. Harvested produce is placed inside a sealed vacuum chamber. When the pressure drops below the saturation pressure corresponding to the product temperature, surface water flashes into vapor, rapidly removing latent heat and cooling the product uniformly.

Target Applications:

Leafy greens (lettuce, spinach, bok choy, Chinese greens)
Mushrooms (button, shiitake, oyster, king oyster, enoki)
Soft fruits (strawberries, blueberries, bayberries, lychee, longan)
Cut flowers (roses, lilies, chrysanthemums)
Herbs (mint, basil, cilantro, celery)
Greenhouse / hydroponic produce

Market Position: Compared to larger multi-pallet models (CVF-1500+), the CVF-500A-1P offers a lower investment threshold with a smaller footprint. Its 500kg per batch capacity matches the daily harvest of small-to-medium farms, making it the ideal entry-level solution for direct farm supply, community distribution, and export-grade produce.

Key Benefits:

Speed: 20~30 minutes per cycle (cold room: 2~4 hours)
Low Water Loss: just 1~2% (cold room air-drying loss: 3~8%)
Uniform Cooling: chamber temperature variance ≤±1°C
Quality Retention: vibrant color, fresh texture, extended shelf life
Plug & Play: 380V/50Hz/3P standard supply, easy installation
