What is the cold chain?
The cold chain is keeping a perishable product within a defined temperature range from the moment it is produced until it reaches the consumer. The chain metaphor is not accidental: once one link breaks, no matter how well the rest of the journey is managed, the freshness that was lost does not come back. Even a short interval of raised temperature permanently shortens shelf life.
The links in the chain
For a typical food product the chain runs through these links: production or harvest, pre-cooling, bulk storage, transport, the store's back-of-house and finally the display cabinet. Each link is managed with different equipment and often by a different business. The retailer directly controls only the last two links — but that is exactly where the customer judges the product.
Where does the chain break?
Breaks usually happen not when equipment fails but during transitions. Goods waiting on the loading bay at intake, the time taken moving stock from the back room to the cabinet, overfilling the cabinet and doors left open for long periods are the most common causes. None of these produces a fault record, which is exactly why they are hard to notice. Regular temperature monitoring is the only practical way to see a break before the product spoils.
As important as temperature: humidity and air distribution
The cold chain is not only a matter of temperature. When humidity is too low, fruit, vegetables and bakery products lose water and their appearance suffers; when it is too high, condensation forms on packaged goods. Balanced air distribution matters just as much: in a cabinet where cold air does not reach the whole display area evenly, some points stay warm even though the average temperature looks correct.
Protecting the cold chain at the point of sale
A few practical decisions keep the chain intact in the sales area. Not exceeding the cabinet's load line, not blocking the cold air curtain, not leaving products standing while shelves are rearranged, and choosing a door or cover option for product groups that need closed display all come first. Where the cabinet sits in the store matters too: placing it near the entrance, near heat sources or on a façade in direct sunlight forces the same cabinet to work under harder conditions.
The right equipment for the product group
Not every product group wants the same conditions. Dairy products, meat products and fruit and vegetables are stored in different temperature ranges; frozen products belong to an entirely separate class. This is why a sales area's cold chain is not built with a single type of equipment. When multideck cabinets, serve-over counters, cold rooms and the central system are planned together, the final link of the chain is strengthened as a whole.
Yaşarsan Refrigerating's cold chain solutions
Since 1988 Yaşarsan Refrigerating has been producing the equipment that builds the cold chain at the point of sale: multideck cabinets, serve-over counters, upright freezers, promotion cabinets, modular cold rooms and the central refrigeration systems that feed them. The temperature class suited to your product group and sales area is determined together with our technical team. Get in touch to discuss your project.
