LDH liquid nitrogen
Industrial use
In industrial production, liquid nitrogen obtained by compressed liquid air fractionation can be used as deep refrigerant. Because of its chemical inertia, it can directly contact with biological tissue and freeze immediately without destroying biological activity, so it can be used as deep refrigerant
(1) Rapidly freezing and transporting food, or making ice products;
(2) Research on low temperature physics;
(3) Demonstrate the low temperature state in science education. At room temperature, a soft object soaked in liquid nitrogen will be as brittle as glass;
(4) Provides the temperature required for high temperature superconductors to show superconductivity.
(5) It can be used as refrigerant to quickly freeze biological tissue to prevent tissue damage.
(6) It is used for industrial nitrogenous fertilizer.
(7) For chemical detection.
Liquid nitrogen is a liquid with a low temperature of - 196 ºC and is obtained from nitrogen which occupies more than 70% of the air. Inert, colorless, non-toxic, volatile, very wide range of use. Liquid nitrogen is easy to volatilize at low temperature, so it is generally stored in a special container liquid nitrogen tank.
According to the use of liquid nitrogen purity classification, often divided into food grade liquid nitrogen, industrial grade liquid nitrogen. The purity of food grade liquid nitrogen is high, because considering the safety of human consumption, the purity reaches 5 9, that is 99.999%. The purity of industrial grade liquid nitrogen is not as high as that of food grade liquid nitrogen.
In the process of using liquid nitrogen, people often think that the safety is not good, but because of the low temperature of liquid nitrogen, it will gasify immediately when it meets air, so the safety is still guaranteed. Just pay a little attention to safety, and there should be safety awareness in any case.

Our company's core technical personnel are teachers from the Chinese Academy of Sciences, with reliable technology and high product stability. Our liquid nitrogen products have been sold to the United States, Peru, Southeast Asian countries, Germany, Lhasa, China, and are used stably at an altitude of 4500 meters.
Working principle of Liquid Nitrogen Plant
In a Liquid Nitrogen plant, the atmospheric air is first compressed to 7 bar pressure into compressor. This high temperature compressed air is then cooled in the external refrigeration system. Then, the cooled compressed air is passed through moisture separator to trap the moisture from the air. This dry compressed air is then passed through a bed of carbon molecular sieves where Nitrogen and Oxygen are separated from the air. Separated Nitrogen is then allowed to get through Cryo cooler which cools the gaseous Nitrogen to a liquid state at the boiling point of Nitrogen (77.2 Kelvin). Finally, the Liquid Nitrogen gets collected in Dewar's vessel where it gets stored for several industrial purposes.
Uses of Liquid Nitrogen
Liquid Nitrogen is used in many applications because of its very low temperature and low reactivity. Some of the common applications are:
It is used in cryo therapy to remove skin abnormalities
Serves as a source of an extremely dry gas
Freezing and transporting of food products
Cooling of superconductors like vacuum pumps, and other equipment
Cryo preservation of blood
Cryo preservation of biological samples like eggs, sperms, and animal genetic samples.
Preserving of animal's semen
Branding of cattle
Cryosurgery (removing dead cells from the brain)
Quick freezing of water or pipes to let workers work on them when valves are not available.
Protects materials from oxidization.
The shielding of materials from oxygen exposure.
Other applications that include creating Nitrogen fog, making ice-cream, flash-freezing, flowering that shatters when tapped onto a hard surface.
