Description
Technical Field
The invention belongs to the technical field of preservation control, and particularly relates to a cold chain transportation preservation control system.
Background
Cold chain transportation refers to transportation in which the transported goods are kept at a certain temperature throughout the transportation process, no matter in the links of loading, unloading, carrying, changing transportation modes, changing packaging equipment and the like. The cold chain transportation mode can be road transportation, waterway transportation, railway transportation and air transportation, and also can be a comprehensive transportation mode formed by a plurality of transportation modes. Cold chain transportation is an important link of cold chain logistics, so that the cold chain transportation box for keeping food fresh is particularly important in the development of modern society.
The product damage that can lead to the incasement when transporting agricultural and sideline products of current cold chain transport case because the automobile body vibration, the transport case has heat retaining effect simultaneously, nevertheless because the incasement does not have refrigeration plant for the transport case can't effectually carry out the efficient to inside product in long-distance transport and keep warm fresh, thereby causes the inside product of transport case to take place rotten easily.
In view of the above, the invention provides a cold chain transportation preservation control system, wherein the side surface and the bottom surface of a transportation box are provided with buffer mechanisms, and the box bodies are connected through suckers arranged on the side surfaces, so that the box bodies can be conveniently and quickly fixed in a carriage, and jolting and shaking generated in the transportation process of the box bodies can be reduced, thereby improving the safety and the freshness of agricultural products in the cold chain transportation process.
Disclosure of Invention
