Everyone knows that refrigerated trucks can be divided into many types, but what are the advantages of different types? Refrigerated trucks are one of the important tools for transporting fresh food. What makes them different from other transportation tools? Next, let's take a look. Refrigerated cars are divided into four categories: First, mechanical refrigerated trucks. Compressed refrigeration units are installed in the cars of the mechanical refrigerated trucks, so that the temperature inside the car can be automatically controlled, so whether it is short-distance or long-distance transport and transport of special refrigerated goods It is very suitable. There is also better insulation of the compartments of mechanical refrigerated trucks , which can reduce the temperature inside the vehicle. Its refrigeration unit not only occupies less space, but also weighs less. Has the characteristics of safety and reliability, not easy to fail. The second is the liquid nitrogen refrigerated truck. The biggest feature of the liquid nitrogen refrigerated truck is that the device is relatively simple, the initial investment is relatively small, and its cooling rate is very fast, and it can maintain the quality of food better. At the same time, the best thing is that there is no noise. Compared with the mechanical refrigeration device, it has a lot of weight reduction. However, as we all know, the cost of liquid nitrogen is relatively high, and how liquid nitrogen is supplied during transportation is a problem. If it is a long-distance transport, it is necessary to prepare a large liquid nitrogen container, which will reduce the amount of cargo. . Third, the refrigeration equipment of frozen-plate refrigerated trucks and refrigerated-plate refrigerated trucks uses the frozen plates with cooling capacity for cooling. The biggest advantage of a refrigerated plate refrigerated truck is that the temperature inside the vehicle is stable, and no noise is generated when it is cooled. At the same time, its failure is relatively small, the structure is relatively simple, and the investment cost is relatively low. Of course, it is also flawed. Its cooling time is limited, so it is only suitable for short-distance and long-distance transport. It is not suitable for long-distance transportation. The fourth is the dry ice refrigerated truck. The equipment it uses is also very simple. The biggest advantage is its relatively low investment cost and no noise. However, the temperature of the interior of the dry ice refrigerated truck is uneven, the speed of cooling is also very slow, and the cost of dry ice is relatively high. Different refrigerated trucks have their own shortcomings, but these will not affect their enormous role.
