The so-called reefer container is a specially designed container with a certain heat insulation performance, which can maintain a certain low temperature and is suitable for the refrigerated storage and transportation of various foods. The reefer container appeared in the late 1960s. The reefer container has a light steel frame, which is affixed with steel plates or light metal plates inside and outside, and the two plates are filled with thermal insulation materials. Commonly used thermal insulation materials are glass wool, polystyrene, foamed polyurethane, etc.
1. The reefer container has high utilization rate of loading volume, flexible operation scheduling and strong economical use.
2. The reefer container can be hoisted in the whole container, with high loading and unloading efficiency and relatively low transportation cost. The structure and technical performance of the new reefer container are more reasonable and advanced, and have a wide range of applicability.
3. Under certain conditions, reefer containers can be used as movable cold storages to adjust market supply and bring good economic benefits to marketers.
4. The reefer container can be used for intermodal transportation of various means of transportation, and there is no need to change the goods in the middle, and the goods can be kept in the required low temperature state uninterruptedly.
5. For international "cold chain" transportation, it can achieve "country-to-country" direct transportation from the origin to the point of sale, which provides the best storage and transportation conditions to ensure the freshness of various foods.
Container size standards are commonly 20-foot, 40-foot high container, flat container, open top container, freezer, etc. The usual 20-foot container and 40-foot container refer to the length of the container, and the foot here refers to feet and inches.
