nitrogen application ：

Nitrogen-filled packaging is widely used in the packaging of fried food, puffed food, baked food, fresh sliced agricultural products, special cheese and fresh meat. Nitrogen-filled packaging can better maintain the taste, taste and nutrition of food. Nitrogen can suffocate and inhibit the reproduction of bacteria in food. The purpose of using nitrogen is to exclude oxygen and slow down the oxidation and respiration of food. Moreover, the solubility of nitrogen in water and oil is small, and the adsorption of food to nitrogen is relatively high. Small, therefore, it can be used as a better gas for food preservation and preservation.

Process ：

Compressed air enters the small nitrogen generator through the filter. Under the action of food-grade carbon molecular sieve, oxygen is absorbed by the molecular sieve, and nitrogen is transported from the outlet to the point of use or mixed with other gases. Pressure swing adsorption adopts the principle of one group of work and one group of regeneration to achieve the purpose of recycling.

Scope of application: 

Modified atmosphere packaging and nitrogen packaging of fruits, vegetables, flowers, tea, puffed food and egg yolk pies, European-style egg rolls, etc.
