Field-generated nitrogen solutions for the food industry

 

Nitrogen is an inert gas that accounts for atmospheric79%, can be distilled from ordinary air. However, companies that use this product in their daily operations know that it is not as simple as what we breathe, and it is much more expensive. The main method of obtaining nitrogen for industrial use is to transport it on site in liquid form, which must be transported and stored at low temperatures. But, in fact, what is the point of converting nitrogen into a liquid for transportation, transporting it to the place of use and then converting it into a gas?

 

 

Application of Nitrogen in Food Industry

Nitrogen as a food preservative has been widely accepted as a non-chemical method of food preservation because it can improve the quality and expand the supply of perishable goods without leaving any chemical residues. In addition to preservation, compact nitrogenPSA generators have a variety of applications in the food packaging industry, including packaging, fluff and headspace displacement. Control the atmosphere storage and oxidation control of perishable food; spray liquid/wine; cover process operation to prevent combustion; beer distribution; cleaningCylinderand vessels; and pest control and fumigation.

Storage

Nitrogen does not react with surrounding elements and can be used to displace oxygen in agricultural storage facilities, thereby slowing the maturation process. Nitrogen slows down the ripening process and keeps the fruit alive during transportation to reach the gas purity level specified for various products; the purity of the ideal atmosphere for storing vegetables and fruits should beBetween 95% and 99%. The process also displaces the carbon dioxide produced by the respiration of the product in the storage space.

Packing

In order to prevent oxidation and deterioration of raw food ingredients, nitrogen is used in food packaging to achieve a meaningful shelf life. Almost every type of packaged food can beIt thrives in an atmosphere of 99% pure nitrogen, including potato chips, meat snacks, peanuts, and other oil snacks that are sensitive to oxygen. By using 99% gaseous nitrogen in the processing and packaging of coffee, the oxidation of flavor oils can be minimized, thereby extending the shelf life and increasing profitability for merchants and retailers. Edible liquids can also benefit from the use of nitrogen. Purging the liquid and the headspace between the bottle and the lid of the container and replacing it with nitrogen can extend the shelf life by 500 percent. Juices may require 99.5 percent pure nitrogen, and many breweries not only use 99 percent pure nitrogen to purge the headspace, but also purge the entire bottle before filling it. Even poultry seeds are sometimes packed with nitrogen.

Pest control and fumigation

In addition to its preservative properties, nitrogen also has the ability to kill insects that eat grain. As government regulators seek alternatives to ozone-depleting pesticides, nitrogen as a pest-killing chemical is becoming increasingly popular. The recent increase in sales of organic fruits, vegetables and grains shows that consumers are also increasingly aware of the dangers of chemical ingestion.
