Cold-chain logistics coloration temperature scale

Abstract

The invention provides a cold-chain logistics coloration temperature scale which comprises a substrate layer, a temperature indicating layer and a protective layer. The substrate layer is the bearing subject of the temperature indicating temperature scale. The temperature indicating layer is arranged above the substrate layer. The protective layer covers the upper surface of the temperature indicating layer. The temperature indicating layer comprises a number of temperature-sensitive coloration layers. The temperature-sensitive coloration layers are successively coated on the upper surface of the substrate layer. Each temperature-sensitive coloration layer is corresponding to different discoloration temperatures. The color of each temperature-sensitive coloration layer is different after discoloration. The specific color of each coloration layer can be visually seen through the protective layer, and then the temperature of an item can be derived based on the color. The temperature-sensitive coloration layer corresponding to the maximum temperature uses a permanent discoloration temperature-sensitive paint, and permanently remains a coloration state after temperature rise and discoloration. Whether chain scission occurs in a cold-chain transportation process can be visually determined, and then whether the cold-chain item is still in a normal state is determined.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics, in particular to a color temperature scale for cold chain logistics that can intuitively obtain the temperature. Background technique [0002] At present, many specific foods and medical vaccines that have corresponding requirements for storage temperature need to be equipped with relatively complete low-temperature cold chain transportation equipment during transportation to ensure the freshness and reliability of food and medical vaccines. The broken chain of the cold chain link, food and medicine are pre-cooled at the place of production and loaded into the transport vehicle to reach the wholesale market at the place of sale, and finally enter the retail link for storage. In these links, the broken chain of the cold chain is prone to occur. [0003] The cold chain is broken, which means that the refrigerated environment cannot be kept at the specified low temperature during transp...

Problems solved by technology

[0002] At present, many specific foods and medical vaccines that have corresponding requirements for storage temperature need to be equipped with relatively complete low-temperature cold chain transportation equipment during transportation to ensure the freshness and reliability of food and medical vaccines. The chain of the cold chain is broken. Food and medicine are pre-cooled at the place of production and loaded into the transport vehicle to reach the wholesale market at the place of sale, and finally enter the retail link for storage. In these links, the cold chain is prone to break

[0003] The broken cold chain means that the refrigerated environment cannot be kept at the specified low temperature during transportation, and the temperature of the storage environment of food or medicine during transportation rises. Through heat exchange, the temperature of food and medicine in transportation rises together. When the temperature rise exceeds When the temperature reaches a certain value, the refrigerated food or medicine can be regarded as spoiled and can no longer be eaten or used normally. In the end, the receiver or consumer will bear the corresponding loss
