CMS Nitrogen Generation for Food Packaging

Carbon Molecular Sieve (CMS) Nitrogen Generator for Food Packaging

Nitrogen plays a crucial role in food packaging by creating an inert atmosphere that slows down spoilage and extends shelf life. In modern packaging operations, especially those using Modified Atmosphere Packaging (MAP), the demand for high purity nitrogen is continuous and precise. Carbon Molecular Sieves enable food makers to generate nitrogen on-site through PSA, so they avoid external supply and ensure consistent purity for sensitive packaging.

What Does Modified Atmosphere Packaging (MAP) Mean?

Modified Atmosphere Packaging (MAP) is a method where the natural air inside a food package is replaced with a specific gas mixture. In most cases, includes high nitrogen and low oxygen levels. The purpose is to slow microbial activity and oxidative spoilage, which are the primary causes of food degradation.

How CMS Nitrogen Generation helps in Food Packaging?

• Nitrogen Injection: PSA generators with CMS separate oxygen from air, producing ultra-dry, pure nitrogen. After filling, a nozzle injects precise nitrogen into the package headspace.
• Oxygen Removal: This nitrogen instantly displaces oxygen inside the package, creating a clean, dry, and inert environment around the food product.
• Immediate Sealing: The package is sealed within fractions of a second after nitrogen injection. As a result, traps the nitrogen gas inside.
• Extended Shelf Life: With oxygen and moisture removed, the nitrogen atmosphere prevents oxidation, preserves freshness, maintains texture and flavor, and significantly extends the product’s shelf life without preservatives.
• Reliable, Onsite Operation: From CMS nitrogen production to package sealing, the process runs quickly, reliably, and cost-effectively right on the production line.

Advantages of CMS Nitrogen Generation for Food Packaging

• On Site, On Demand Supply: Eliminates cylinder deliveries and the risk of running out of gas.
• Moisture and Oil Free Output: Keeps packaged foods dry, fresh, and free from contamination.
• Longer shelf life: Nitrogen pushes nearly all oxygen out of the package. Therefore, with below 0.5% oxygen, fats stay fresh, colors stay bright, and mold growth slows.
• Cost Effective and Operationally Efficient: Cuts nitrogen costs, compared with bulk or bottled supply. Uses only ambient air; no chemicals or liquid cryogens are required.

Why CMS Nitrogen Generation is Essential for Food Packaging?

• Prevents Oxidation and Spoilage: High purity nitrogen effectively displaces oxygen in snack bags and meal trays. As a result, oxidation slows down, preventing flavor loss, color fading, and the breakdown of vitamins.
• Extends Product Freshness: Using nitrogen ensures snacks stay crisp, fats do not become rancid, colors remain vibrant.
• Produces High Purity Nitrogen On-site: Carbon Molecular Sieve (CMS) within the PSA nitrogen generator selectively adsorbs oxygen. Thus, it produce continuous streams of pure nitrogen (typically 99.5% purity or higher) directly at the production location.
• Maintains Dryness in Powdered Foods: Dry nitrogen prevents powdered products from clumping and ensures they remain free flowing and easy to handle.
• Protects Fragile Food Items: Nitrogen acts as a cushioning gas, filling food packages. It shields delicate products like chips and crisps from damage during transport.
• Reliable and Immediate Nitrogen Supply: With an on-site CMS nitrogen generator, you get instant supply, so you avoid delivery delays, prevent downtime, and reduce logistics.
