Nowadays, most of China's development relies on refrigerated truck refrigerators, including drugs and vaccines used in hospitals, as well as fresh fruits, vegetables, seafood, and other items that require low-temperature storage to prevent material loss inside

The current Chongqing refrigerated trucks can be said to have added various functions, not only can they quickly achieve refrigeration effect, but also have good effects on the preservation of goods. In addition to their basic functions, including transportation in the later stage, methods are also needed.

3. Frozen foods, such as frozen meat, seafood, frozen foods, etc. These foods generally require storage temperatures below -18 ° C and can be stored for several months to over ten months.

During the transportation of these foods in hours, it is only necessary to set the temperature inside the compartment at -18 ° C, and there is no need to strictly control the accuracy of temperature fluctuations. This type of food should be transported by F-class refrigerated trucks.

2. Refrigerated foods, such as fresh meat, seafood, poultry eggs, etc. The transportation temperature requirement for this type of food is to ensure that the food does not freeze, and the lower the temperature, the better, that is, close to 0 ° C or lower.

This type of food requires transportation in refrigerated trucks of grades D, E, and F. Some canned foods require a transportation temperature of around -5 ° C and are transported using E and F grade refrigerated trucks.

3. Vegetables, fruits, etc. The transportation of this type of food is relatively complex in refrigerated transportation.

The temperature requirements for various vegetables or fruits are different; Secondly, many vegetables or fruits have high requirements for temperature fluctuations and cannot deviate significantly from the set temperature; Thirdly, due to the fact that vegetables and fruits still require respiration after harvesting, respiratory heat is generated, thus requiring refrigeration units to provide more cooling capacity.

In addition, this type of food also has requirements for relative humidity, so although refrigerated trucks from A to F can be used for transporting vegetables and fruits in principle, the carrier's technology and experience are very important.
