Refrigerated trucks

Refrigerated trucks are those trucks, which are used to transport the goods, which are of perishable nature, and thus, needs very low temperatures for their transportation. The refrigerated trucks can be a van truck or any other truck that can carry goods at extremely low temperatures. The reader must clearly understand that the refrigerated trucks and the insulated or ventilated trucks are not the same. In the ventilated or insulated trucks, there are no cooling devices fitted for providing extremely low temperatures. The insulated or the ventilated trucks are those trucks that use to carry fruits etc. Let us now discuss the various types of refrigerated trucks available in the market.

TYPES OF REFRIGERATED TRUCKS

There are many types of refrigerated trucks available in the market. It can be an ice-cooled truck or it can be fitted with various types of mechanical refrigeration systems, in order to provide the low temperature. There are also refrigerated trucks that use carbon dioxide gas in order to provide low temperatures. A person also finds many refrigerated trucks that use certain types of liquids as a cooling agent for the low temperatures. When the number of goods or the size of consignment that is to be sent is big, or in case the distance to be covered by the refrigerated truck is large, articulated trucks are mostly used. These trucks carry the refrigerated vans or semi trailers. Let us now discuss some of the related aspects of refrigerated trucks.

RELATED ASPECTS OF REFRIGERATED TRUCKS

Let us now discuss some aspects of refrigerated trucks. As said above also, these trucks are used for the transportation of perishable goods. These include foodstuff, chemicals, pharmaceutical products etc. One of the main problems that are faced by the refrigerated trucks is that since the outside temperatures vary to a great extent, it becomes difficult to keep the low temperature or the deep freeze temperature inside constant. If the temperature rises, there is every likely that the perishable goods inside would decay or deteriorate. As the refrigerated trucks have to move on road, there are many bumps, vibrations etc encountered.

To save the goods from these, it is very important that there is rigid polyurethane foam in used in the refrigerated truck which can easily save the goods from different types of jerks. It is to be noted here that in the present times, the use of polyurethane is gaining importance and it has now become the core material in the production of refrigerated trucks. These are mostly used as the sandwich elements. There are certain features that can be easily attributed to this material. Like it has high mechanical strength but has low weight, it provides high insulating capacity but the wall thickness is quite low; there are no cold bridges as the material is made of self supporting structure and the price is quite economical. So, it is advised that if any transport company wishes to buy a new refrigerated truck, it must be ensured that it invariably contains polyurethane.

There must be heat insulation materials used in the refrigerated trucks. The refrigerated trucks must also have long-term thermal conductivity, which can easily be attained by means of diffusion proof facings. Temperatures as low as ?35 degree Celsius are also have to be maintained some times and thus, it is very important that water must be prevented from diffusing through various channels. Almost all the refrigerated trucks that are manufactured by companies of good repute of international presence take care of all these aspects.

In the present times, there is a new concept regarding the refrigerated trucks that is gaining importance. It is the RFID systems. This is basically a wireless system that is used for the monitoring of low temperatures inside the refrigerated trucks. This system has been developed by a UK company and it helps the managers to keep eye constantly on the temperatures inside the refrigerated truck trailers etc. At the time of parking or when the truck is being loaded, it is very important to keep the low temperature constant in order to prevent the goods from getting deteriorated.

There are transmitters that are used in RFID system and these have a range of about 300 meters. This enables the inspector to get the temperature inside the refrigerated truck. The RFID is dependent on the devices that can use store and retrieve the data wirelessly. These are called as the tags or transponders. This tag is basically a small object that can easily be incorporated into the animal or the product.

Thus, all the food safety requirements regarding low temperatures can easily be maintained.

The temperature checks of the refrigerated trucks gain more importance when trucks are standing in the yard. There are inspectors employed for the above purpose and it is their duty to ensure that the transporters are maintaining the temperature conditions are required.

In the present times, it has been made possible to measure the temperature inside the refrigerated van when it has been uncoupled from the trucks by way RFID.

As far as the usage is concerned, the refrigerated trucks are used in all the countries to transport perishable goods. These trucks have a great impact on the economy of the nation. For example, in the United States, there is great demand of different types of meat products. Thus, refrigerated trucks are used frequently here to transport the meat products in order to meet the increasing demand. If, due to any reason, the refrigerated truck stop working, it would of course affect the economy.

THUS, REFRIGERATED TRUCKS ARE VERY USEFUL

Refrigerated trucks are used to transport the perishable goods from one place to another. There are many types of refrigerated trucks that are available in the market now days. In the present times, there are many devices and technologies that are used in these trucks to ensure that the low temperatures are maintained throughout the journey. There are many countries in which these trucks are used extensively and thus, they have a great impact on economy also.
