With the development of my country's economy, consumers are increasingly demanding the quality of food materials. As fresh food materials are an important part of daily consumption, cold chain logistics to ensure their quality is particularly important. At the same time, with the rapid development of my country's fresh food e-commerce, consumers' demand for cold chain logistics is diversified, and more stringent requirements are put forward for the functions of cold chain terminal distribution equipment. In the circulation stage before delivery, suppliers of fresh food ingredients can usually guarantee the cold chain circulation of fresh food ingredients, but in the distribution stage of fresh food ingredients, the chain is often broken. Consumers have the characteristics of small batches, multiple varieties, and multiple frequencies when purchasing fresh ingredients. Because different fresh ingredients have different storage temperature requirements, for fresh food e-commerce, supermarkets and other merchants must control the temperature during the delivery of fresh ingredients. It's a pain point.

The delivery stage is constrained by the types of fresh ingredients, distribution equipment, cost, etc., and the delivery personnel cannot guarantee that the fresh ingredients are at an appropriate delivery temperature. In addition, the flexibility and flexibility of distribution equipment also has a great impact on the distribution of fresh food merchants. At present, most of the market is based on single temperature control, which cannot realize the temperature control of distribution equipment. At present, for the delivery of fresh ingredients, the more common delivery method is to use "foam box + ice pack" for single-temperature cold preservation or without any cold preservation measures, which cannot meet the requirements of fresh ingredients for distribution temperature. Therefore, the quality of fresh ingredients in the delivery stage There are usually large changes, especially for temperature-sensitive ingredients, which are prone to more losses. At the same time, the lack of flexibility of distribution equipment leads to the need for equipment of various specifications, which increases the difficulty and cost of distribution.
