Description

Technical Field

[0001] The present invention relates to the technical field of pork chop cold chain logistics, and in particular to pork chop cold chain logistics equipment and method for preserving pork chop freshness. Background Art

[0002] Pork chop cold chain logistics refers to a systematic project that ensures the quality of pork chops and reduces losses by keeping them in a specified low-temperature environment at all stages of production, storage, transportation, sales and before consumption. Cold chain logistics is particularly important for perishable foods such as pork chops, which can ensure that they remain fresh and safe throughout the entire supply chain.

[0003] The development of pork chop cold chain logistics can help improve food quality and safety, reduce economic losses, and meet consumers' demand for fresh and healthy food. However, the implementation and management of cold chain logistics also face many challenges, such as technology updates, cost control, and regulatory compliance. Therefore, continuous improvement and innovation are the key to promoting the development of pork chop cold chain logistics.

[0004] In the existing cold chain logistics of pork chops, long-distance transportation is often carried out by trucks, and the truck compartments have a refrigeration function, so that the transported pork chops can be refrigerated for transportation. However, the storage method of pork chops in the existing cold chain transportation is box stacking, which causes the temperature of the pork chops in the middle of the box to be higher than the temperature of the upper and lower stacks, causing the middle pork chops to easily deteriorate during transportation. In addition, since the pork chops often need to be inspected during transportation, and the existing box stacking method for refrigerated storage is difficult to conveniently inspect, the cold chain transportation time is too long.

[0005] To this end, we propose a pork chop cold chain logistics equipment and method that is easy to preserve freshness. Summary of the invention
