Meat cold storage temperature and refrigeration requirements
Meat facilities carry three distinct refrigeration duties — carcass chilling, chilled holding and frozen storage — each with a different load profile. Combining them into one nominal cold room specification is a frequent cause of under-performance.
| Condition | Indicative temperature | Humidity | Engineering note |
|---|---|---|---|
| Carcass chilling | 0 to +4 °C air | 85–90 % RH | High pull-down duty immediately after slaughter. |
| Chilled storage / cutting | 0 to +4 °C | 85–90 % RH | Cutting rooms carry substantial internal heat gains. |
| Frozen storage | −18 to −25 °C | 90–95 % RH | Long-term and export-grade frozen meat. |
| Blast freezing | −30 to −40 °C air | n/a | Sized on batch mass and required core temperature. |
Values are indicative planning ranges used for early-stage refrigeration sizing and procurement. They do not replace product-specific food-safety, pharmaceutical, regulatory or customer requirements, which take precedence in every case. Confirm final conditions with your quality function and a qualified refrigeration engineer.
Refrigeration engineering considerations
Chilling duty vs. holding duty
Carcass chilling load peaks sharply after slaughter and then falls. Plant sizing must cover the peak; control strategy should avoid running the whole plant at peak all day.
Weight loss and humidity
Air velocity, humidity and coil temperature difference influence evaporative weight loss, which is a direct commercial cost in meat operations.
Hygiene and washdown
Panel finish, floor drainage and coil coatings are part of the refrigeration specification in meat plants.
Zoning
Separating chilled, freezing and dispatch zones reduces cross-infiltration and improves temperature stability.
