Cold food cold chain logistics for the expansion and development is quite fast, cold storage construction is already very common. Because there are certain advantages, coupled with the development of cold chain logistics is now more and more fruit and vegetable origin. By cold storage, cold chain logistics development also reflects China's further development. With the improvement of living standards now, people growing demand for fruits and vegetables, but the same kind of fruit and vegetable production time is affected by the climate there is a certain limit, fruit and vegetable production of light, the season is very clear, in order to meet people demand for fruits and vegetables, we choose to build cold storage of fresh vegetables, which is the installation of cold storage, and installation of cold storage for fruit, vegetable storage is also very convenient. Currently cold storage installation types are also several good points: the installation according to the temperature of cold chain logistics can be divided into: 12 ~ -2 ℃ high temperature library, and the library -2 ~ -10 ℃ temperature, the low temperature of -10 ~ -20 ℃ library, freezing cold -20 ~ -30 ℃, the quick-freezing cold of -30 ~ -40 ℃, -40 ℃ ultra-low temperature below the library, there is a library for rapid cooling, depending on the temperature of the items to be cooled design cold temperatures. Installed by cold chain logistics capacity can be divided into: large cold storage ≥10000t and medium-sized refrigerator of 5000 ~ 10000t, 1000 ~ 5000t of small and medium sized refrigerator, <1000t a small refrigerator. Cold storage installation in accordance with the nature of their use can be divided into: the production of cold: the production of cold is usually some major food manufacturers and fish, meat processing and the construction of cold storage, such as: Frozen -30 ~ -40 ℃ cold storage and so on. Distribution of cold: cold chain logistics is a transit and distribution of cold reserve was mainly large storage capacity, is generally used to regulate the supply of seasonal demand on the market guaranteed. Retail cold storage: generally built in large food stores or markets inside the city, for the temporary storage of retail food, and some food and beverage industry will also need to build, cold storage capacity is small, the storage time is short, cold temperatures can vary according to the requirements Some important and improve international competitiveness of food; not only for the world to improve food distribution; also ensure that the original can be a good quality of food; can increase the value of agricultural Vice: For this one of the important technologies for cold chain logistics One technique. Cold chain logistics can be chosen according to different storage refrigeration equipment items, such as cold storage and preservation of fruits and vegetables you can use the cooling pipes, but can not use the chiller, avoid direct impact of wind and cold storage in the fresh fruit and vegetable products. Construction and installation of cold storage cold chain logistics in rural and vegetable origin and food base has become a very effective way to help increase economic efficiency. Now cold chain logistics are installing high degree of automation, and reliable performance, good preservation effect, economical and practical, civil construction Ran refrigeration installation of various cold storage, cold storage of fruits and vegetables fresh, frozen frozen cold storage, cold storage refrigeration maintenance of a range of services.
