Dairy cold storage temperature and refrigeration requirements
Dairy sites often combine several narrow temperature bands on one campus — raw milk, ripening, chilled finished goods and hard-frozen ice cream — which makes zoning and plant staging the central design questions.
| Condition | Indicative temperature | Humidity | Engineering note |
|---|---|---|---|
| Raw milk / chilled dairy | +2 to +4 °C | 80–85 % RH | Tight tolerance; continuous receipt in many plants. |
| Cheese ripening / maturation | +8 to +14 °C | 80–95 % RH | Humidity control is as important as temperature. |
| Butter / frozen dairy | −18 to −25 °C | 90–95 % RH | Long-term frozen holding. |
| Ice cream hardening & storage | −25 to −35 °C | 90–95 % RH | Hardening tunnels require lower temperatures than storage. |
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
Humidity control
Cheese maturation rooms need controlled humidity, not just controlled temperature; this changes evaporator selection and control strategy.
Multiple temperature classes
Separate plant staging or multi-temperature systems avoid running the whole site at the coldest requirement.
Heat recovery
Dairy plants have continuous hot-water demand, which often makes refrigeration heat recovery economically attractive.
Hygienic construction
Washdown regimes and CIP areas influence panel, floor and coil specification.
