Ever notice how a new bag of potato chips seems partially filled with air? It’s not air. It’s nitrogen gas. During the packaging process, nitrogen pushes the oxygen out of the bags, extending the shelf life of the product. It also provides a cushion that protects the integrity and quality of the chips. Other applications of nitrogen in food processing including fluffing, head space replacement, blanketing of process operations to prevent unwanted combustion, and pest control and fumigation.
The air we breathe is about 78% nitrogen. Higher purity nitrogen is generated by separating nitrogen molecules from other molecules within a clean, dry compressed air stream, resulting in a purified supply of nitrogen.
Companies that generate their own nitrogen in-house with a nitrogen gas generator enhance production flexibility by ensuring they have the nitrogen they need, at the level of purity they need, when they need it. Generate nitrogen in-house with a nitrogen gas generator and there is no worry about running out because there is no third-party supplier. This eliminates constant order processing, refills and delivery costs. It also frees up space otherwise needed to store nitrogen bottles (both full and empty).
