What is the benefit of using PSA Nitrogen Plants in the Food Industry?

PSA Nitrogen Plants in Food Industry

Nowadays, packaged foods are more popular than unpackaged foods, and people think that packaged foods are better in quality. To keep packaged foods fresh, smelling good, and crispy for a longer time, it’s important to fill the space inside the packaging with nitrogen gas. Scientifically, nitrogen gas is not reactive, which means it won’t cause the food to go bad or become stale. That’s why food packaging companies use nitrogen gas from PSA nitrogen plant food to give your food a longer shelf life and keep it in its normal state.

Companies that deal with food and drinks need a continuous supply of nitrogen gas from a PSA nitrogen plant for their packaging processes. Sometimes, there might be delays in getting nitrogen gas, which can cause problems for the food packaging. It’s not a good idea to leave processed or made food without packaging for too long. To avoid these problems, it’s a good idea to install a PSA nitrogen plant food unit, which can produce nitrogen gas on-site. With a PSA nitrogen plant manufacturer unit, the flow of nitrogen gas will never be delayed or stopped.

How Do PSA Nitrogen Food Plants Work?

PSA nitrogen generators use a smart way to take out nitrogen from regular air. They have special units called adsorption beds filled with a material that can grab oxygen molecules.

The process starts by pushing compressed air into these beds. The material inside grabs the oxygen, allowing only the nitrogen to pass through. This gives us a stream of pure nitrogen gas.

But after some time, the beds get full of oxygen they’ve collected. So, the generator releases the pressure and lets the oxygen go. This cleans the beds, and they’re ready to absorb oxygen again.

The generator keeps switching between the adsorption beds, creating a continuous supply of high-purity nitrogen gas. This nitrogen is then used for things like food packaging, where it helps keep products fresh for longer.

The genius of PSA generators is their ability to separate nitrogen from air efficiently, without using complex chemical processes. Plants made by an expert PSA nitrogen plant manufacturer are a reliable and cost-effective way to produce the nitrogen needed for many industrial and commercial applications.


Evolution of Nitrogen Supply Methods in the Food and Beverage Industry

In the food and beverage industry, nitrogen is essential for various processes, including packaging and preservation. Traditionally, companies relied on methods like high-pressure cylinders or liquid nitrogen containers to supply nitrogen. However, a growing trend is towards in-house nitrogen generation systems. These systems offer advantages such as efficiency, cost savings, and sustainability.

There are several methods through which nitrogen is supplied in the industry:

  • Nitrogen Cylinders: High-pressure cylinders store nitrogen gas and deliver it to the site when needed.
  • Bulk Nitrogen Gas Systems: Larger facilities opt for bulk gas systems, where nitrogen is delivered and stored in cryogenic tanks in large quantities.
  • Nitrogen Generators: On-site nitrogen generators are gaining popularity. These systems extract nitrogen from the air using technologies like Pressure Swing Adsorption (PSA) or membrane separation.
  • Liquid Nitrogen Tanks: Liquid nitrogen is supplied in bulk tanks and vaporized into gas before use.

Among on-site nitrogen generation methods, two main technologies are prevalent:

  • Pressure Swing Adsorption (PSA) Nitrogen Technology: This process separates nitrogen from other gasses in compressed air using carbon molecular sieves (CMS). Oxygen and other gasses are adsorbed, allowing nitrogen to pass through for collection.

Membrane Nitrogen Technology: This method utilizes selectively permeable membranes to separate nitrogen from other gasses in compressed air. Nitrogen permeates through the membrane while other gasses are trapped and removed.

Benefits Of PSA Nitrogen Plant In Food Industry

Maintain Integrity of Products:
Nitrogen gas plays a crucial role in preserving the quality and integrity of food products during packaging. This is one of the main benefits of the PSA nitrogen plant in the food industry. When used in the packaging process, nitrogen minimizes oxidation and prevents unwanted flavor changes that typically occur in the presence of oxygen. This gas creates a protective atmosphere, stabilizing raw materials such as cooking oils or seasonings, ensuring their taste remains intact throughout the product’s shelf life.

Prevents Aerobic Microbial Growth:
Oxygen can promote the growth of microorganisms, posing a significant risk to the safety and quality of food products, particularly fresh produce, meats, and ready-to-eat items. By modifying the atmosphere within the packaging with nitrogen, you can effectively inhibit the growth of these microbes, ensuring that your products remain safe for consumption. Incorporating higher levels of nitrogen in the packaging environment can significantly reduce the risk of microbial contamination.

Increases Distribution Distances:
The presence of oxygen can accelerate the decomposition process, leading to a shorter shelf life for food products. By blanketing the packaging with food-grade nitrogen gas, you can significantly prolong the shelf life of your products. This extended shelf life allows for increased distribution distances, enabling you to reach broader markets and expand your customer base without compromising product quality.

Unlimited Supply of Nitrogen:
When considering the benefits of PSA nitrogen plants in the food industry, onsite generators cannot be missed. Implementing an on-site pressure swing adsorption (PSA) nitrogen generator offers a sustainable and cost-effective solution for nitrogen supply. Unlike relying on external suppliers, an on-site generator provides an unlimited supply of high-purity nitrogen gas tailored to your specific needs. This not only ensures consistent product quality but also eliminates the need for recurring purchases or deliveries, streamlining your operations and reducing overall costs.
