China cold storage solution provider
A blast freezer (IQF or tunnel-style) isn’t just a cold room—it’s a production-critical system that freezes food from +15°C to –18°C in under 4 hours, locking in texture, color, and nutrients. Without it, seafood turns mushy, meat loses yield, and ice cream forms large ice crystals.
But how much does a commercial blast freezer really cost—and how much can it actually freeze and store?
Spoiler: The real question isn’t “per square meter”—it’s “how many tons can you freeze per day?”
📦 Two Capacities Matter: Freezing vs. Storage
| Type | Purpose | Measured In |
|---|---|---|
| Freezing Capacity | How much fresh product you can freeze per 24 hours | Tons/day |
| Storage Capacity | How much frozen product you can hold after freezing | Tons (static) |
✅ Example: A poultry plant may need to freeze 20 tons of chicken/day but only store 60 tons total (shipped weekly).
