Self-production of food nitrogen

E941 food nitrogen generators

Since 1979, Claind has been meeting the demands of companies operating in the food industry, which need to use nitrogen generators for packaging food in a protective atmosphere and for storing liquid foods.

Specifically designed for preserving perishable products.

Claind’s line of FOOD nitrogen generators has been specifically designed for preserving perishable products and guarantees the quality of E941 food nitrogen in compliance with current regulations. Nitrogen prolongs the shelf life of products and retains the organoleptic properties of food, preserving its freshness and making it more appealing in terms of colour, shape and composition.

Specifically designed for <strong>preserving</strong> perishable products.

Specific technology to produce food nitrogen.

Claind’s solutions for nitrogen self-production use PSA (Pressure Swing Adsorption) technology. In order to constantly provide our customers with high[1]quality solutions and innovation, we have further improved PSA technology by designing and registering the exclusive international FAST PURITY® patent

Specific technology to produce <strong>food nitrogen.</strong>

Designed to support your work.

The Claind food nitrogen generators are incorporated into our customers’ production processes and have been designed for the following Food & Beverage applications:

 Packaging in a protective and modified atmosphere. - image

Packaging in a protective and modified atmosphere.

This packaging technique consists in replacing the air that is in contact with the food inside the packaging with the most appropriate nitrogen mixture to prolong the product’s shelf life.


By shelf life we mean the period of time during which a product maintains its sensory characteristics (colour, smell, taste, etc.). These properties are of paramount importance for the simple fact that the consumer’s acceptance or rejection of the product depends on them. Moreover, it is worth highlighting that, through the use of nitrogen, various treatments can be eliminated with chemical or physical stabilisers, thus improving the final quality of the packaged food. Nitrogen also performs a filling function to prevent the packaging from collapsing on the product. In this way, the following advantages can be obtained:

  • fresh products that retain their organoleptic characteristics
  • longer shelf life
  • increased product marketability
  • reduced product losses due to waste or returns, higher quality and food safety levels
Storage of liquid foods. - image

Storage of liquid foods.

In order to protect liquid foods, nitrogen is used to neutralise storage tanks, for bottling and in all phases of transfer and handling of liquid products to evacuate dissolved oxygen.


Inerting consists in replacing the air that is in contact with food with gaseous nitrogen so that the product can be preserved for longer. In fact, when in contact with air, liquid foods develop a series of oxidative reactions that change their chemical composition and radically change their colour, smell and taste. Nitrogen, instead, maintains an inert atmosphere inside the tank that allows food, thus protected, to retain its qualitative and organoleptic characteristics. The same principle also applies to bottling, where nitrogen is used during the final phase of liquid treatment for bottle washing (pre-evacuation), for actual bottling and before capping for the inerting of head space.

  • In the coffee packaging process
  • In the wine production process
  • In beer protection and preservation processes
