Chongqing refrigerated truck editor will talk about frozen foods on the market. If you observe carefully, it is not difficult to find that whether it is the freezer in supermarkets, the refrigerator at home, or the refrigeration machine in cold chain transportation, their refrigeration conditions are basically minus 18 degrees Celsius. Why is it 18 ℃? But not minus 10 ℃?

We need to understand that low temperatures do not eliminate microorganisms, but rather inhibit their reproduction and the decomposition of physical objects. According to the temperature adaptation range of microorganisms, they can be divided into thermophilic bacteria, thermophilic bacteria, and psychrophilic bacteria, and psychrophilic bacteria only stop reproducing at minus 18 degrees Celsius.

Generally speaking, thermophilic bacteria that cause food poisoning do not produce toxins at temperatures below 3 degrees Celsius, while molds only stop growing at -15 degrees Celsius. Moreover, the temperature of minus 18 degrees Celsius in the freezer does not consume electricity, which can save a considerable amount of expenses over the course of a year.

In reality, when transporting these frozen foods, the temperature of the refrigerated truck is not fixed at minus 18 degrees Celsius, but is controlled based on the nature of the goods. If you carefully observe the car body, you will find that different English letters are sprayed on the refrigerated truck.
