Refrigerated transport is a technique of moving cargo that has epical temperature requirements. Doing this by road means using a vehicle with temperature control capabilities. Essentially, the vehicles keep your perishable products at a desired temperature to prevent them from going bad in transit. Decades ago, transporters relied on crude methods such as placing salt and ice below temperature-sensitive goods. That has changed with time. Today's transporters rely on state-of-the-art methods and devices to keep perishable goods from going bad. Keep reading to understand the technique used by your service provider to keep your goods fresh during delivery:
Dry ice is one of the simplest ways to achieve temperature control when transporting perishable goods. It is ideal for heavy-duty refrigeration for big containers in transit. The dry ice often referred to as solidified carbon dioxide, remains at low temperatures of about -78 degrees Celsius for a long time. Additionally, dry ice undergoes sublimation that converts it directly from a solid to a gas. The resulting gas is non-toxic and poses no threat to the integrity of your perishable goods.
On the downside, dry ice requires careful handling because it can cause painful burns when it comes into contact with a handler's skin. Moreover, the gas produced when temperatures rise replaces the oxygen in the room. This can lead to asphyxiation in a small, unventilated trailer.
Special Specimen Kits
What other perishable products can you think of besides food? Well, items like biological specimens, medical samples and experimental chemical extracts require transportation within certain temperatures. In this case, the best option is to use special specimen kits that allow unique variations in the temperature during transit. For example, you can opt for pre-freezable bottles to set the right temperature tone for incoming perishable items. You can also choose heavy-duty freeze packs built to keep specimens below freezing points when vehicles pass through high-temperature zones.
Blankets and Drum Heaters
Seemingly, the focus of refrigerated transport is to keep perishable items cold and safe from the intrusion of external heat. What happens when the outside surrounding is too cold for your cargo's good? You need to protect the perishable items from external freeze and thaw. Typically, blankets and drum heaters will come in handy in such cases. The devices sustain product flow and apply controlled heat distribution to prevent heat loss from the products you are transporting. Usually, both blankets and drum heaters come in user-friendly designs that pose no risk to your transport crew.
