Nitrogen Generators for Food Packaging

Food Packaging

One of the easiest ways to extend the shelf life of your packaged food is with nitrogen gas. This is because it displaces oxygen and moisture, which can cause mold, mildew, and other quality issues. Here at On Site Gas, we offer nitrogen delivery systems that can be used with food processing and packaging equipment.

Nitrogen for Food Processing

Using nitrogen for food processing is extremely important for preventing discoloration (due to oxidation), bacteria and mold development, and changes in taste and texture. During food manufacturing and processing, nitrogen can be used to flush tubes, pipes, and containers before moving the product through the system. It can also be used to flush and fill glass jars, bottles, cans, plastic containers, and plastic and cellophane bags where food will be stored until it is purchased and consumed.

Nitrogen Gas in Food Preservation

Nitrogen gas is used in food preservation, most commonly during a technique known as flushing. The process involves placing the food into its container and filling it with nitrogen. The nitrogen displaces the oxygen, forcing it out of the bag. The package is then sealed tightly to prevent the nitrogen from escaping. This process increases the shelf-life of the food and adds a layer of cushioning, which is extremely important for fragile foods, like chips, pretzels, and popcorn.

Vacuum Packing with Nitrogen

Vacuum packing foods is an effective way to increase shelf-life because it removes all of the air inside the package prior to sealing it. However, even the best vacuum packing machines may still leave a small amount of oxygen in the bag. Vacuum packing with nitrogen is a great way to mitigate this. During this process, nitrogen is introduced into the package before it is vacuum-sealed, which displaces any existing oxygen. Then, the vacuum seals the package by removing all of the air. Nitrogen vacuum packing is ideal for delicate items, as the gas provides a cushion that helps to prevent breakage.

Trust On Site Gas for Your Nitrogen Needs

On Site Gas has been manufacturing high-quality nitrogen generators for over three decades. We offer standard and custom nitrogen generators for the food processing and packaging industries. This includes Pressure Swing Adsorption (PSA) nitrogen generatorsmembrane nitrogen generators, and engineered nitrogen systems. The type of generator you choose will depend on your overall purchase and installation budget, as well as your desired nitrogen purity levels. For example, if you need 99 percent purity, a nitrogen membrane generator may be best for you. Or, if you want a generator that will provide you with a quick return on your investment and low year-round nitrogen production costs, you may want to choose a PSA system. We also offer a variety of refurbished generators if you are looking for a more budget-friendly option.
