Applications of Nitrogen Generators in the Food Industry

语言切换示例

Prevents Oxidation: As an inert gas, nitrogen displaces oxygen in the package, stopping fats and sugars from oxidizing and causing discoloration, off-flavors, or rancidity.
Freshness & Nutrient Protection: Filling packages with nitrogen slows microbial growth and preserves freshness and nutrients.
Examples: Used for cured meats, seafood, nuts, coffee, fresh produce, and ready-to-eat meals to extend shelf life.

Snack Foods: Chips and popcorn require an “air cushion” of nitrogen to prevent breakage during transport and storage.
Liquid Protection & Headspace Purging: In beverage and liquid food packaging, nitrogen replaces headspace air to prevent oxidation and spoilage.

Blanketing Process: Creates an inert atmosphere to prevent self-heating or oxidation of oils and flammable materials in storage or packaging.
Pest Control: High-purity nitrogen fumigation in grain and nut storage replaces chemical treatments, offering an eco-friendly and effective solution.

Beer Production & Transfer: Nitrogen is used to purify piping, assist in beer transfer, and reduce excessive foaming.
Wine Bottling: Bottle purging before and after corking removes residual oxygen, protecting acidity, color, and aroma.
Other Beverages: Juices and functional drinks also benefit from nitrogen headspace purging to maintain flavor and quality.

Generation Methods: PSA (Pressure Swing Adsorption) or membrane separation isolates nitrogen from compressed air, delivering continuous, high-purity (≥99%) nitrogen.
On-Site Production Advantages:
- Stable Supply: Eliminates reliance on cylinder deliveries and risk of shortages.
- Cost Savings: Up-front investment in a generator reduces recurring cylinder rental or purchase costs.
- Space Efficiency: Frees up storage space by avoiding large cylinder inventories.

Flexible Usage: Ideal for short-term projects or peak seasons, rent a generator to produce nitrogen on-site as needed.
Purity Options: Available in 99%, 99.9%, or 99.99% purity grades, with parallel operation to meet high-flow demands.
Containerized Unit: Indoor/outdoor ready, fast setup and commissioning, easy to relocate and deploy.
