In the grain storage industry, utilizing the chemical properties of nitrogen can put grains in a dormant and oxygen deficient state, slow down their metabolism, and achieve good insect, mold, and spoilage prevention effects, without contaminating the grains. Filling various types of grain piles such as rice, wheat, barley, corn, and rice with nitrogen can prevent insect infestation, prevent overheating, and prevent mold growth, so that the grain can smoothly pass through the summer. This method involves tightly sealing the grain with plastic cloth, first creating a low vacuum state, and then filling it with nitrogen gas with a purity of about 98% until the internal and external pressures are balanced. This can cause oxygen deficiency in the grain pile, reduce the respiratory intensity of the grain, inhibit the reproduction of microorganisms, and all pests will die within 36 hours due to oxygen deficiency. This method of reducing oxygen and killing insects can not only save a lot of costs (about one percent of the cost required for fumigation with highly toxic drugs such as zinc phosphide), but also maintain the freshness and nutritional value of food, prevent bacterial infection and drug contamination.

Sa diha nga ang hangin sa pressurized pinaagi sa pagputli ug pa-uga, Base sa Aerodynamics, nitrogen ug oxygen sa hangin sa zeolite molekular sieve (ZMS) sa Pressure tabyog adsorption ang performance sa lain-laing mga pagsabwag rate pinaagi sa adsorption sa nitroheno. Ang oxygen sa carbon molecular sieve sa ibabaw sa diffusion rate mas taas kay sa nitrogen. Kung ang adsorption dili balanse, ang oxygen masuhop sa carbon molecular sieve sa daghang gidaghanon, ug ang nitrogen gikonsentrar ug gipadato sa gas phase aron makab-ot ang pagbulag sa oxygen ug nitrogen.
