4 Tips for Refrigerated Cargo Transportation
The maintenance of food quality during its transportation makes a world of a difference for the suppliers and clients alike. Restaurants, food factories and local markets depend on the day to day supply of fresh food. Thanks to refrigerated cargo, fresh food can be transported over long distances, without risking the spoilage of food and ruining the order. No supplier would want to bleed out profits in vain like this. Commercial refrigerated haulers maintain the right storage temperature of the cargo that it carries, no matter how long the journey is. This sophisticated engineered electrical system provides freezer trucks of today, the ability to carry foods that are vulnerable to spoilage over long distances. It is important to remember that no matter how well your refrigerated transportation system works, food safety and food quality isn’t only dependent on the truck’s ability to maintain a particular temperature. There are other factors concerning handling that influence it. Here are four ways you can ensure that your cargo is loaded properly and will be completely safe during transit.
Don’t forget to chill the goods before loading
Quite often, people confuse the function of a freezer trucks refrigeration unit and assume the truck is going to change the cargo’s temperature to its desired storage temperature. This is not true and too many frozen food cargos have lost their quality along the way because of this malpractice. The truck’s refrigeration unit is actually designed to maintain the temperature of the load, not to change it. So make sure, that the goods are the optimum storage temperature before they’re loaded, so that after you load them, the truck’s temperature controlled compartment will take it from there to maintain the temperature of the goods from there on out.
Cool the truck before loading
For the same reason as mentioned above, it is also a bad practice to start cooling the truck after loading the cargo because the truck must have some retained heat energy from its walls, floors, roofs and enough surfaces, to transfer its heat into the cargo that will absorb the heat from the truck, in case the truck is not cooled to the right temperature before loading the goods.
Don’t stop the transit
Make sure that at any given point, the cargo does not sit on an un-refrigerated dock for too long. You can’t afford to allow the load to heat up the slightest or else it will warm up the cargo, jeopardize the good’s quality and develop hot spots on the loading dock that can warm up the cargo on it.
Space cargo appropriately
Loading the goods closely packed with each other reduces the surface area to volume ratio of the cargo, which basically means you’ve minimized the surface area exposed to air for heat exchange, and you don’t want that. This can also result in poor air distribution and, consequently, the production of hot spots along with short cycling refrigeration system. So, make sure you keep a distance of 2 inch from the sidewalls and sparsely place the cargo with gaps between them to allow for effective airflow. Also, avoid making the rookie mistake of blocking the refrigeration system’s evaporator vent with cargo.
