Although China's production profession starts relatively slowly and develops relatively backward compared with developed countries, in the trend of innovative science and technology, China's domestic companies struggle to advance, constantly introducing new concepts and developing new skills in manufacturing operations, which lays a solid and thick foundation for domestic nitrogen machines and promotes the acceleration of domestic production occupations.

In industrial production, many materials or finished products need to be packed with nitrogen to be retained for a long time, because it is easy to lead to the reproduction of microorganisms in an oxygen environment, making the material moldy and bad. Not only that, in metallurgy, metal processing occupations, petrochemical occupations, electronic occupations, etc., nitrogen is widely used as a maintenance gas, which has also increased the speed of development of China's nitrogen machine occupation.

However, with the development of modern society faster and faster, all walks of life on the need for progressive power is also very urgent, after the purchase of bottled nitrogen can not meet the needs of modern industrial development. In this need, the presentation of the nitrogen machine completes the improvement of the nitrogen production power in the industry. The real sense of the nitrogen machine appeared in the middle of the nineteenth century, the industrial revolution liberated the production capacity, improved the production power, especially the food, pharmaceutical occupation of nitrogen demand greatly increased, so the need for nitrogen machine is very large, nitrogen machine formed a mass production, nitrogen machine as a separate occupation independent development. After hundreds of years of continuous progress, the structure of nitrogen machine products has gradually been improved, and various types of nitrogen machines are suitable for the special use of all walks of life. In particular, the presentation of modular nitrogen machines in the 21st century represents the development of China's nitrogen machine skills in the direction of higher scientific and technological content.

The start of China's nitrogen machine occupation is very late compared with developed countries. However, after the continuous exploration of China's nitrogen machine occupation, it has also obtained certain results in skills. At present, China's nitrogen machine occupation has formed a considerable industrial scale, the production of nitrogen machines can now be completely satisfied with the needs of the domestic market, and the previous history of Chinese industry relying on imported nitrogen machines is completed.

In summary, the development of China's nitrogen machine occupation, although China's nitrogen machine occupation started late, but has now entered a relatively sophisticated stage of development, domestic nitrogen machine in chemical industry, medicine, food, metallurgy, electronics and other industries play a huge effect. Trust with the continuous development of science and technology, China's nitrogen machine skills will certainly be able to get a greater break in the future development.
