What Is the Standard Temperature for a Freezer Warehouse?

The temperature standard for a freezer warehouse is not a single fixed value but is strictly graded and refined according to national food regulations, industry norms, and the characteristics of different goods.

I. National Statutory Baseline: -18°C

According to the explicit provisions of the "National Food Safety Standard for Food Cold Chain Logistics Hygiene" (GB 31605-2020), the storage environment temperature for food requiring freezing shall not exceed -18°C. This is the "bottom line" that all freezer warehouses must adhere to. In actual operations, to cope with temperature fluctuations caused by door openings or equipment defrosting, enterprises typically lower the internal control setpoint to around -20°C and require temperature fluctuations to be controlled within ±2°C.

II. Subdivided Temperature Zones and Special Cargo Requirements

With the refined development of cold chain logistics, freezer warehouses are further subdivided to meet the needs of different goods:

Standard Freezer Warehouse (-18°C to -25°C): This is the most common low-temperature cold storage range, mainly used for long-term storage of meat, aquatic products, ice cream, and other foods.

Blast Freezer (-35°C to -40°C): Mainly used for rapid freezing of food, allowing the core temperature to quickly pass through the "ice crystal formation zone," thereby preserving the integrity of cell structures to the greatest extent.

Ultra-Low Temperature Cold Storage (-45°C to -60°C and below): Designed specifically for high-value or special goods, such as long-term preservation of premium tuna, storage of special research materials, or biological samples.

III. Dynamic Operations and Temperature Control Details

Temperature management in a freezer warehouse involves not only static indicators but also dynamic operational standards. During door-opening operations such as loading and unloading, due to the exchange of hot and cold air, the temperature rise of food must be strictly controlled within 3°C. Additionally, for designated storage cold stores such as those for imported meat, the temperature difference between day and night must not exceed 1°C to ensure absolute stability of quality.

IV. Hardware Configuration and Compliance Management

To achieve the stringent temperature standards mentioned above, freezer warehouses have specific requirements in construction and operation. The warehouse body typically uses 150mm to 200mm high-density polyurethane insulation panels and is equipped with continuous temperature recording devices with over-limit alarm functions. At the management level, cold stores must establish a comprehensive temperature and humidity monitoring system, ensuring 24-hour uninterrupted recording (at intervals not exceeding 30 minutes), and develop strict deviation handling and emergency response plans.

In summary, the temperature standard for a freezer warehouse is a system with -18°C as the statutory baseline, extending to lower temperatures based on the characteristics of the goods. When constructing a cold store, enterprises must strictly align with national standards and combine them with the specific characteristics of the goods to be stored for precise design, ensuring food safety and quality.
