In recent years, imported seafood, meat, dairy products and fruits have become consumers’ new favorites.
However, imported food needs to take the "express" of liquid nitrogen and cold chain to better ensure its fresh quality, meet the needs of consumption upgrades, and enter the world's major markets as much as possible.
Most food imports require a "long journey" in temperature, so their freshness has attracted much attention.
So, how can imported seafood, meat, dairy products and fruits remain fresh during long-distance transportation?
On the one hand, the use of liquid nitrogen refrigeration technology from the source, and then the use of liquid nitrogen quick freezers, cold chain and other refrigeration equipment, not only can maintain the fresh taste of the product, but also prevent the generation of harmful substances.
Naturally mature durians are susceptible to infection by sol bacteria and are difficult to store and transport over long distances. In order to ensure the safety of durian exports, some Chinese exporters screened, cleaned and packaged durians, and then used low-temperature liquid nitrogen freezing technology for rapid freezing to ensure the transportation quality of fresh durians.
As a kind of refrigeration equipment, the liquid nitrogen quick-freezer adopts low-temperature liquid nitrogen refrigeration technology. It can use -110℃ low-temperature quick-freezing and other fresh fruit products. The liquid nitrogen quick-freezer only takes a few minutes to completely freeze, and the center temperature can reach -18°C. The taste of the fresh fruit product can be maintained afterwards, as fresh as before.
On the other hand, in storage and transportation, cold chain logistics is used. Because imported fresh products take a long time, even if liquid nitrogen refrigeration technology is used from the source, if it is stored at room temperature during transportation, temperature changes will inevitably accelerate the reproduction of bacteria and microorganisms in the product, leading to deterioration or Shorten the shelf life. In the early stage of China's cold chain logistics development, China had fewer refrigerated trucks, reefer containers and reefer containers than developed countries, which made it difficult to sell and import products across regions.
Now, with the rapid development of the domestic cold chain product market, the rapid growth of China's demand for refrigerated trucks and other refrigerated equipment has been promoted to a greater extent, and the overall demand and share of the refrigerated truck market has shown a stable trend. Upward trend. As of the end of 2018, the number of refrigerated trucks nationwide reached 180,000, a year-on-year increase of 40,000, an increase of more than 28% year-on-year, and the growth rate remained above 20 percent for five consecutive years. Since the refrigerated truck can maintain constant low temperature storage and transportation and continuous refrigeration, it provides technical support for the fresh quality of imported products.
At present, driven by globalization, scale and industrialization, driven by national policies, and driven by consumer demand, liquid nitrogen quick freezers and cold chain driven refrigeration have become my country's largest manufacturing industry. While the fresh quality of imported products such as Chinese aquatic seafood, meat, dairy products and fruits is guaranteed, the industry will also usher in the development of higher quality.
