Traditional food preservation generally has to add vacuum, but neither of the two ways can better extend the freshness period of food or is harmful to the human body. Our company specifically for the requirements of food preservation, the development of food nitrogen machine, especially for food preservation. Before food packaging, the bag is filled with high-purity and high-cleanliness nitrogen, so that there is almost no oxygen in the bag, so as to prevent food oxidation, extend the food freshness shelf life, and it is a physical method of preservation, will not have any harm to the human body. This technology has been widely used in Europe and the United States, and some high-end food products in China have also adopted this method. All parts of the food nitrogen machine are imported, and the cleanliness is very high, and according to the needs of users or the special requirements of food with sterilization kettle and filter.
Applicable to:
1, beer, wine, fruit wine, cooking oil, pressure can, blow bottle, capping before use, can remove oxygen to prevent carbonated drinks and cooking oil oxidation, * and fading. If the cork cork is used, it can prevent the cork inside the bottle from appearing mildew.

3, pastry, baked goods, egg yolk pie: the general preservation time can be extended by 3-5 months or more. Nitrogen filling can prevent deformation and crushing during transportation
4, milk powder, soy milk powder: the use of trace nitrogen can prevent or reduce milk powder long-term extrusion storage caused by caking phenomenon.
5, cereals, nuts, fruits, vegetables: filled with 95% of the purity of nitrogen, you can prevent the harm of pests, leaving 5% of the oxygen can also reduce the respiration rate of the fruit, the preservation effect is obvious.
6, candy, small food: mainly suitable for the use of non-breathable bag packaging. Same effect as 2 and 3
Gas flow rate: 1-300Nm³ / h;
Product gas purity: 95-99.9995%;
Outlet pressure: 0.1-0.6 (adjustable)
