Refrigerated trucks you don’t know about “cold†knowledge
When summer arrives, it is the peak period of using a refrigerated truck. Only the correct use and operation of a refrigerated truck can guarantee the complete delivery and preservation of the goods. Because refrigerated trucks are used exclusively for temperature-sensitive products, the guarantee of temperature is the key to refrigerated trucks. Improper use or improper operation can result in the goods not being stored or shipped in good condition. How to use a refrigerated truck normally? How to avoid the risk caused by improper use?
Correct use
During transportation, temperature control is necessary if the temperature is too high or too low to load the refrigerated car carrier, and the refrigerating device is again set to the necessary temperature of the transport cargo, and the temperature of the cargo is lowered or to a necessary temperature for a certain period of time. . In fact, on the contrary, the goods not only cannot drop in temperature (or go up), but instead cause the goods to be damaged or deteriorated.
Refrigerated cars are not cold storage, and refrigeration units are mainly insulated.
The chiller that owns this car is not refrigerated and frozen in many people's concepts. The chiller unit can be loaded into the cargo frozen or heated to the desired temperature.
Prior to loading, the car must be pre-cooled or warmed up
Before loading, the car must be pre-cooled or warmed up for about 1.5 hours.
Turn off the unloading of the chiller assembly cargo, the temperature loss of the reefer box is slower
During the discharge, during the discharge process, the refrigeration unit must be turned off. During the loading and unloading of the goods, the refrigeration unit is not closed. Many people think that this can make the temperature of the goods rise slowly. In fact, this is a very wrong understanding.
Pay attention to the discharge of goods, and keep the circulation of cold air in the compartment
Their cargo must take into account the cold air circulation in the refrigerated compartment, the best cargo can be stacked on a double-sided tray fresh cargo tray without wrapping plastic film, plastic, film will block cycle air-conditioning cycle to stay in the top of the car and the goods The distance between more than 23 cm. Floor refrigerated trucks usually have a road ventilation slot, but some do not, do not operate double-sided pallet loading to ensure that the air conditioning cycle at the bottom of the floor.
