Because nitrogen is inert at room temperature and is not easy to breed bacteria, it is widely used in the preservation and storage of beverages, fruits, vegetables, pastries, tea, Chinese herbs, pasta and other foods, which can fully maintain the original color, aroma and taste, and its storage quality is obviously better than mechanical refrigeration.

In the field of food storage and preservation, the need for nitrogen is not the higher the purity, the better, the food in the preservation process, the ambient gas containing trace oxygen can get a good preservation effect.

In order to meet the nitrogen requirements of the food industry, on the basis of the general food nitrogen machine, combined with the characteristics of the food industry, the company has specially developed a special food nitrogen solution with a purity of 95% to 99.9% and adjustable purity, and on the basis of combining different food with different nitrogen purity requirements, to achieve excellent preservation effect.
Equipment characteristics

1. Purity can be adjusted in the range of 95% ~ 99.9%, nitrogen drying, low dew point, conducive to food preservation;

2. Excellent price performance, fast investment recovery;

3. Simple appearance, compact structure, small footprint, easy to clean, to meet the high cleanliness requirements of the food industry;

4. Mature process, the use of high-quality components, durable.

Nitrogen is chemically inactive and is a colorless, odorless, inert gas that cannot be burned. Nitrogen is the main cost of air, accounting for 78%, and is not easy to pass through the packaging film compared with other conventional gases, so in the food industry, the use of food nitrogen production mechanism to take nitrogen for the main filling gas in the air conditioning packaging system.

Nitrogen is used in nitrogen-filled packaging, which is rapidly replacing traditional vacuum packaging in the packaging of fried foods, freshly sliced agricultural products, special cheeses and fresh meat. Nitrogen-filled packaging can better maintain the taste, taste and nutrition of food, and its application field is expected to further expand.

Most of the deterioration of food is oxidation reaction under the participation of O2, and promote the reproduction of microorganisms and bacteria, resulting in food spoilage. As an asphyxiating inert gas, N2 has an asphyxiating and inhibiting effect on bacterial multiplication in food. The purpose of using N2 is to eliminate O2, slow the oxidation and respiration of food, and the solubility of N2 in water and oil is very small, the adsorption effect of food on N2 is also small, therefore, it can be used as a better food preservation gas.

In addition, nitrogen-filled packaging can also play a good role in protecting the shape of the food inside: prevent crispy and fragile food from being crushed; To avoid the imbalance of internal and external pressure so that the packaged food is bonded together under pressure, so that its texture becomes hard; Even the irregular shape of the food can maintain the appearance of the packaging body surface, reduce the surface folding caused by packaging material damage and food deterioration.

Nitrogen quality is the key: gas quality is an important factor in the packaging of food air conditioning. The packaging has strict regulations on the purity of N2, the gas used must reach the pure nitrogen grade, that is, food grade, and the content of impurity components in the gas must be lower than the safety limit standard that does not endanger human health. The main impurity components in N2 are O2, CO, CO2, CH2 and H2, etc. The national standard of pure nitrogen has specific provisions for their content.
