In recent years, with the vigorous development of China's economy, people's demands for quality of life have become increasingly high, and the requirements for freshness of food have also become stricter. The cold chain transportation industry has also experienced rapid development. Chongqing refrigerated truck editor provides a detailed introduction to the importance of refrigerated trucks in the cold chain transportation industry, helping you gain a deeper understanding of refrigerated trucks and the cold chain industry.

As an important component of the cold chain transportation industry, refrigerated trucks are enclosed box type transport vehicles that act as knights of cold chain products, maintaining the temperature of frozen or fresh goods. Refrigerated trucks are commonly used for transporting frozen foods (refrigerated trucks), dairy products (dairy transport trucks), vegetables and fruits (fresh goods transport trucks), and vaccines and drugs (vaccine transport trucks).

A suitable and high-performance refrigerated truck can reduce the loss of cold chain products to a relatively low level. A refrigerated truck consists of a specialized walking part for the car chassis, a heat-insulating compartment body (usually composed of polyurethane materials, fiberglass, color steel plates, stainless steel, etc.), a refrigeration unit, and a temperature recorder inside the compartment. For other vehicles with specific requirements, such as meat hook trucks, optional accessories such as meat hooks, cargo blocking troughs, aluminum alloy guide rails, and ventilation troughs can be added.

The body of refrigerated truck manufacturers is usually painted with the words B or C, mainly to distinguish between refrigerated, refrigerated, insulated, and constant temperature refrigerated trucks used for transporting goods. The refrigerated truck will be painted with one of A, B, C, D, E, F, G, or H on the body, with eight letters symbolizing the eight refrigeration levels of the refrigerated truck.

According to the different types of goods being transported, we can choose a suitable grade of refrigerated truck. The average temperature of A-class carriages is 12 ° C to 0 ° C, B-class carriages is 12 ° C to -10 ° C, C-class carriages is 12 ° C to -20 ° C, D-class carriages is ≤ 0 ° C, E-class carriages is ≤ -10 ° C, and F-class carriages is ≤ -20 ° C.

The above is the carriage temperature used for transporting perishable food cold chain products. The transportation of biological products mainly involves G-class and F-class carriages, with an average temperature of 8 ° C to 2 ° C for G-class carriages and ≤ -20 ° C for H-class carriages.
