If you are transporting refrigerated goods (even if you’re simply hiring a mobile cold room for the weekend) there are a few things you need to know to ensure the quality of these products is maintained…
This applies whether you are transporting meat, beverages, fresh produce or pharmaceuticals.
Read on to ensure you’re doing the required things to keep your refrigerated goods in the best shape possible…
The ‘Never Warmer Than’ Rule
Every product that requires refrigeration has a temperature zone that needs to be maintained to avoid the growth of bacteria that can cause disease and can spoil an entire load of goods.
The “Never Warmer Than’ rule, as explained in the Australian Food Cold Chain Logistics Guidelines, dictates that:
“CHILLED FOODS must be transported, stored and handled at temperatures NEVER WARMER THAN +5°C; and FROZEN FOODS (including ice creams) must be transported, stored and handled at temperatures NEVER WARMER THAN -18°C.”
This rule should be followed whenever temperature sensitive products are being transported to ensure a safe temperature is maintained.
Mixing Loads – Managing Heat Transfer
It’s a fact of life that hotter items will warm cooler items, so effectively managing heat transfer when transporting refrigerated goods is crucial.
As stated in the Australian Food Cold Chain Logistics Guidelines:
Heat can flow in three ways:
- Conduction: A cooler product in contact with a warmer product will be heated up.
- Convection: The air around a warm product can heat up which can heat up other products nearby.
- Radiation: Warm products heat up surrounding products, like the grill element in an oven.
It’s wise to ensure all products in the same refrigerated transport vehicle or cold storage environment require the same temperature. However, this is not always possible as new products are introduced to the load which may be of a slightly different temperate…
To ensure all products stay at their required refrigerated temperature, the following techniques can be used:
- Utilise a “settling in” space for incoming products or distance new items;
- Use temperature loggers to monitor temperatures;
- Store sensibly; keep heat sensitive fresh products away from new products.
Maintaining The Refrigeration System
When transporting temperature sensitive products by refrigerated vehicle any mechanical failure can lead to your products being spoiled.
Effective maintenance of refrigerated vehicles is essential. This should include running defrost cycles after delivery, and checking seals on doors and windows regularly to maintain the performance of the refrigeration system.
