The Cold Chain: Why Unbroken Temperature Control Matters
A cold chain is the unbroken path of temperature control that keeps frozen or chilled food at the correct temperature from the moment it leaves the production facility until it reaches the end consumer. For frozen exports, the target is usually -18°C or lower — and any prolonged exposure above that temperature begins to degrade quality.
The cold chain has several links:
1. Freezing at source. Products are frozen to the required temperature immediately after processing, using IQF tunnels or blast freezers.
2. Cold storage at the factory. Finished goods are stored in dedicated freezer warehouses with continuous temperature monitoring.
3. Reefer loading. Refrigerated shipping containers (reefers) are pre-cooled before loading and loaded quickly to avoid temperature spikes.
4. Ocean or land transport. GPS-enabled temperature loggers record the temperature inside the container throughout the voyage. Any deviation is flagged.
5. Port handling and customs. This is the most vulnerable link — delays at port or customs can expose the container to ambient heat. Experienced exporters plan paperwork in advance to minimize dwell time.
6. Destination cold storage. The importer's warehouse receives the goods and continues cold storage until distribution.
7. Last-mile delivery. Refrigerated trucks deliver to retail or food service customers.
A single weak link compromises the entire chain. At SANDA, we handle our own freezing, storage, loading, and reefer monitoring — and work only with proven shipping partners to ensure the product that leaves our facility arrives in the same condition it was packed.
