Nitrogen for mixing and packaging products

Mixers are used in various areas of product manufacturing, including the chemical, pharmaceutical, metal and food industries. When mixing dry and powdery products as well as liquids and chemicals, an inflammable mixture can be formed due to the influence of oxygen. In this context, nitrogen is used for blanketing in order to prevent explosions and fires.

The quality of many foodstuffs changes as a result of contact with oxygen. Certain enzymes that set metabolic processes in motion result in the discolouration and spoilage of goods, for example. In order to delay this process, the packaging of foodstuffs for transport and the time until consumption is realised with the aid of the shielding gas nitrogen. To this end, nitrogen is added to the packaging to displace the oxygen. This nitrogen atmosphere keeps food fresh and durable for longer without the addition of preservatives. This MAP method (Modified Atmosphere Packaging) is mainly used for oxygen-sensitive foodstuffs such as meat, fish, yoghurt and cheese.

But even electronic components can be protected from ageing processes by being packaged in nitrogen dry packs. For this purpose, the components are packed in special bags to which desiccants are added. These are vacuum-sealed and welded after nitrogen flushing. The "removal of oxygen" allows electronic components to be stored safely for a number of years.

With our nitrogen generators, we supply high quality solutions for the stationary and mobile production of nitrogen for different applications, including for low volume requirements.
