On-site nitrogen leads to huge savings in modified atmosphere packaging applications
In today’s global market place there is an increasing demand for fresh food produce with consumers expecting an increasing selection of foods in a “just produced” condition. This is demanded regardless of season and location and all at competitive, affordable prices.
Modified atmosphere packaging (MAP) is a vital component for much of the food and beverage industry and is used to extend shelf life and maintain the quality of fresh produce and perishable products. MAP works by changing the levels of gases in the packaging to help slow down natural spoilage processes. These include the prevention of fungal and bacterial growth, reducing oxidation, and decreasing respiration rates of fruits and vegetables.
Nitrogen is the most widely used gas for MAP purposes and barring a few exceptions, is used in some way for all foods that can benefit from MAP.
The traditional method of utilising nitrogen for MAP is to buy it in from gas companies – with supply methods including high pressure cylinders, liquid mini tanks and bulk storage vessels. However, ensuring that there is a ready supply of nitrogen gas can be logistically problematic and expensive.
What’s the Alternative?
Parker’s Nitrogen gas generators turn air from a standard factory compressor into food grade nitrogen. It means that users will have gas on demand and zero waste (it’s estimated that 10% of cylinder gas goes back to the gas company, whilst liquid nitrogen “boils off” losses each day).
Crucially Parker’s nitrogen gas generator users can save over 90% of their gas costs and achieve a return on investment on the capital cost of the generator in less than 12 months.
Other advantages over traditional nitrogen supplies, which include:
• Food grade nitrogen at consistent flow, pressure and purity
• Enhanced safety without the need to store or handle high pressure cylinders
• Reduced downtime owing to an on-demand supply
• Very low cost of ownership
• No need for expensive civil works prior to installation
• Proven reliability
The Parker MAXIGAS nitrogen gas generator can operate from a standard factory compressed air supply and deliver food grade Nitrogen, E941, fully compliant with EU regulations, without the need for additional purification.
The seven energy saving models feature automatic economy mode, a built in oxygen analyser for continuous purity monitoring, and the modular design offers flow rates for all applications, large or small. The Parker Maxigas also has a user-friendly interface and compact design, which all adds up to a proven money-saving nitrogen gas generator that can increase production and safety in your MAP applications.
But don’t just take our word for it. Thousands of our customers have already benefited from Parker’s nitrogen gas generators. Here is just one of those:
