Fujian Mushroom Farm: 22-Minute Vacuum Cooling Reduces Browning by 60%
An Fujian mushroom farm processes 800 kg per cycle with a CVF-1000A-3P, cooling from 24°C to 3°C in 22 minutes while maintaining 2.1% weight loss and superior color.
The Challenge
Mushrooms are notoriously difficult to cool due to high respiration rate and delicate structure. Conventional cold storage took 6–8 hours to reach 6°C inside the box, resulting in browning and cap opening.
The Solution
CVF-1000A-3P with multi-stage pressure reduction to prevent surface freezing.
Results
| Parameter | Value |
|---|---|
| Inlet temperature | 24°C |
| Outlet temperature | 3°C |
| Cooling time | 22 minutes |
| Weight loss | 2.1% |
| Browning index | Significantly reduced vs. room cooling |
Key Insight
Mushrooms need precise pressure control. Too fast a pressure drop causes localized freezing on the surface. The CVF-series multi-stage pressure reduction avoids this, delivering premium quality with 15–20% higher market price.
