Nitrogen is used to displace the oxygen in food packaging (like snack packages), ensuring that the food is kept fresh and doesn’t age or decay. This prolongs the lifetime of the food and ensures that it’s crisp when you open it!
Now let’s consider your bag of peanuts. To slow their aging process, nitrogen delays oxidation. This slow-down controls the peanuts’ fats and oils and increases the time they stay crisp and fresh. Inside the bags the pockets of space fill with nitrogen, pushing oxygen out of the bag and eliminating moisture and mold.
Nitrogen generators are used on-site in various manufacturing applications beyond beer and peanuts such as wine, potato chips, bird food, vegetables, and fruits.
For all these applications key decisions are having to be made about whether to use on-site nitrogen generators within the manufacturing facilities or have nitrogen bottles and tanks delivered to the facilities on a periodic basis.
A strong case can be made for using on-site generators because they reduce manufacturing delays, equipment storage space needs, and overall costs while increasing safety, reliability, and efficiency.
On-site nitrogen generators run 24-7 and give manufacturers access to nitrogen any time they need it. As such, manufacturers don’t have to wait for nitrogen bottle and liquid tank nitrogen deliveries, which can be delayed and sometimes cancelled.
The up-front costs to buy an on-site nitrogen generator could be a concern for some manufacturers. But in the long run they are likely to accelerate manufacturing processes, reduce waste, and cut costs. By investing in an on-site generation, a brewery could break even within the first two years of installation and, over time, save from 40-75 percent on overall nitrogen costs.
