The difference between cold chain car and refrigerator car
Jan 21, 2021

In the category of fresh cold chain, the difference between the definition of "cold chain" and "cold storage" is often puzzling. What is the difference between a cold chain car and a refrigerator car? Is it the same kind of transportation?
In fact, there are some differences between them. From the definition: the cold chain vehicle is mainly in the whole process of transportation, whether it is loading and unloading, changing the mode of transportation, changing the packaging equipment and other links, so that the transported goods always maintain a certain temperature. Refrigerated vehicle is a kind of closed van type transport vehicle used to transport frozen or fresh-keeping goods. Refrigerated vehicle is a special transport vehicle equipped with refrigeration unit and polyurethane insulation box. Refrigerated vehicle can be classified according to manufacturer, chassis carrying capacity and compartment type. From the definition point of view, there is no doubt that the cold chain car maintains a certain temperature, while the refrigerator car uses the refrigeration unit to keep fresh. Refrigerated transportation: the logistics links of medium and long distance transportation and short distance distribution of food. Refrigerated transportation is the most familiar link. Refrigerated transportation includes the logistics links of medium and long distance transportation and short distance distribution of food. Refrigerated mainly involves railway refrigerated car, automobile refrigerated car, refrigerated ship, refrigerated container and other means of transport, among which the automobile is the main force of refrigerated transportation in China. In the process of refrigerated transportation, the temperature fluctuation is one of the main reasons for the decline of food quality, so the means of transportation should have good performance, at the same time of maintaining the specified low temperature, but also to maintain a stable temperature, long-distance transportation is particularly important.


 Freezing sale is the most common part of daily life. Freezing sale includes freezing storage and sale of all kinds of cold chain food into wholesale and retail. It is completed by manufacturers, wholesalers and retailers. 
With the rapid development of all kinds of chain supermarkets in the city, all kinds of chain supermarkets are becoming the main sales channels of cold chain food. In these retail terminals, a large number of refrigerated / frozen display cabinets and warehouses are used, which gradually become an indispensable part of the complete food cold chain. There are three types of cold chain transportation: fresh-keeping, cold fresh and frozen. For the whole cold chain logistics, people in the special vehicle industry are most concerned about the cold chain transportation. At present, the refrigerated transportation in China is mainly automobile transportation. According to the degree of food processing, cold chain transportation can be divided into primary agricultural products and processed food. Primary agricultural products include vegetables, fruits, meat, poultry, eggs, milk, aquatic products and flower products; processed foods include frozen foods, packaged cooked foods such as poultry, meat and aquatic products, ice cream and dairy products, and fast food raw materials. Different foods have different temperature requirements for preservation, so the types of vehicles needed for transportation are also different. 

According to the different temperatures required for food transportation, cold chain transportation can be divided into three categories, namely: fresh keeping, cold fresh and frozen. Insurance goods include vegetables, flowers, fruits, fresh-keeping vaccines, fresh aquatic products, and the transportation temperature is about 2-8 ℃; cold and fresh goods mainly include sour meat products, river seafood products, bean products, vaccine products, chocolate, etc., and the transportation temperature is between 0 ℃ and - 5 ℃; frozen goods include quick-frozen food, quick-frozen seafood, river fresh products, frozen meat, frozen meat products, etc The transportation temperature should be between - 10 ℃ and - 18 ℃.
