When it comes to liquid nitrogen, laboratories are often used to preserve samples, medical use for liquid nitrogen beauty, frozen embryos, etc. Livestock is used to freeze semen, but when we want to play with liquid nitrogen, it is cruel and requires liquid nitrogen. tank.
Under standard conditions, nitrogen is in a gaseous state and occupies a very high volume, and compression of the gas allows the volume of the container in which it is stored to be reduced by the same amount. An effective method of reducing the volume of gas is liquefaction obtained by compression at low temperatures.
In order to store liquid nitrogen, a liquid nitrogen container is used, which is mainly characterized by high heat insulating ability.
The specific uses of liquid nitrogen in various industries are as follows:
Liquid nitrogen is used for long-term preservation of biological or biological materials. Therefore, it is used to store cell lines for scientific research, semen samples or proteins that are particularly unstable for long-term storage.
When grinding many foods, liquid nitrogen is used to absorb the heat generated by friction, which can cause the product to overheat, causing the product to melt and form undesirable clumps or thermal degradation.
Food and food
Since the beginning of the 21st century, liquid nitrogen has been introduced into the kitchens of large restaurants due to the cooperation between some chefs and scientists active in the field of molecular gastronomy.
Its main use is related to the production of impromptu ice cream, which has been supplied in some ice cream parlors in Italy (the first country in the world) since 2006.
Liquid nitrogen is used in other industries, including chemical industry, scientific research, environmental and medical technology.
Note: Because the temperature of liquid nitrogen is extremely low, we must remember to wear safety goggles, gloves and other equipment when contacting liquid nitrogen.
