Food storage industry
liquid oxygen nitrogen plants are used in food storage to rapidly freeze food, preserving its nutrients, texture, and flavor by minimizing ice crystal formation that can damage cell structure. This process also extends the shelf life of food by preventing the growth of microorganisms, making it ideal for perishable items like fruits, seafood, and meat.
Laser cutting industry
In laser cutting, liquid nitrogen serves as a cooling medium to reduce the temperature of the material, minimizing the heat-affected zone, preventing deformation, and avoiding burn marks, which ensures precision and high-quality cuts. It also accelerates the cutting process, reduces oxidation on the surface, and protects the laser equipment from overheating, thereby extending its lifespan.
