Chilled and Frozen Storage
Maintaining produce at chilled temperatures
If you want to keep produce at chilled temperatures, then use smaller amounts of dry ice in the container and don’t place it directly on the food or drink, but rather in a side compartment or with some kind of buffer or packing between the dry ice and the food. Gel packs are ideal if you only want to keep food and drink chilled without any risk of freezing. Soak Gel packs in water and then place in your freezer to prepare them. You can then distribute them evenly throughout your cooler.
Maintaining produce at frozen temperatures
If you want to keep your produce frozen then use dry ice. Dry Ice slices are ideal as they are individually wrapped and easy to distribute across your cooler or storage carton. 10kgs of dry ice would be suitable for 48 hours of storage. Remember, the better insulated the container the longer the dry ice will last. Fill any remaining airspace in the container with newspaper or some kind of packaging. This helps to reduce the rate at which the dry ice sublimates (turns from a solid to a gas form).
Recommended Product: Dry Ice Slices
Dry ice is widely used for airline shipping and is identified by a Class 9 UN1845 label. We supply these labels on our online store. For assistance calculating how much dry ice you will require, please contact our team with the internal dimensions of your storage container and the expected shipping time. As ambient temperatures can impact the longevity of the dry ice, we recommend using slightly more dry ice than you expect to need or using a Thermosafe Insulated Shipper. These are available in two different sizes and because they offer a greater level of insulation they will hold the dry ice for a longer period of time.
