PACKING REEFERS FOR OPTIMUM USE

Our refrigerated containers can hold huge amounts of cargo and protect it from the outside elements; how you pack the container is key to getting the best value for money. Of course, professional packing takes into account the type of goods and the desired temperature level, so this process is not identical every time.

If you are using refrigerated containers in a professional capacity, it may benefit you to learn about the best packing practices and their impact on the temperature inside the unit; here are some tips:

How Much Space is There Inside of a Reefer?

One of the best traits of refrigerated containers is that almost all of their internal space can be utilised for storage purposes. The size of the actual container naturally plays a significant role, so the first decision you will need to make is selecting a container/containers of adequate size. You can choose between 10ft, 20ft, and 40ft units, which are approximately suitable for holding anything between 4 and 20 standard pallets. Since containers are rectangular and in their original state don’t feature any compartments, goods can be packed in rows and stacks to increase total holding capacity. That’s why the packaging methodology affects the total volume of goods that can be placed inside a reefer.

Ensuring Air Flow is Key to Proper Cooling

Owing to the way cooling systems work, it is necessary to ensure there is sufficient space around the cargo to allow for uninterrupted airflow throughout the container. This is important to ensure that the heat naturally emitted from produce is dissipated, rather than remaining in one spot and potentially raising the temperature locally.

When storing frozen goods, it is essential to understand that circulating air is warmer than the package and to direct it around and not through the goods. In general, you should be mindful to avoid creating ‘pockets' of air inside the container that have no way of escaping or placing goods so close together that circulation can’t occur.

Loading Goods in the Most Optimal Way

Several practical techniques allow for the maximum utilisation of available space without disrupting airflow:

• Goods are usually loaded onto pallets before being stored in containers, it is important that some space between pallets is left free to allow air to circulate.
• Pallets should be aligned with the sides of the container and the top layer of products should not touch the ceiling.
• It is also not good practice to turn on cooling while the container is empty, since this increases the risk of condensation inside the unit.

Adherence to these simple rules can greatly improve the performance of your refrigerated container and guarantee that the goods stored inside it stay fresh and suitable for consumption.
