modified atmosphere packaging equipment

The modified atmosphere packaging technology will play an important role in the intelligent packaging era. With some food and vegetable fresh-keeping products becoming the mainstream of food consumption and occupying an increasing share in the domestic and foreign markets, the application of modified atmosphere packaging machine will greatly prolong the shelf life of food.

Modified atmosphere fresh-keeping gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small amount of special gases. CO2 has the effect of inhibiting the growth and reproduction of most putrefaction bacteria and molds, and is the main bacteriostatic component in the protective gas. O2 can inhibit the growth and reproduction of most anaerobic spoilage bacteria, maintain the color of fresh meat, maintain the aerobic respiration of fresh fruits and vegetables, and maintain their freshness. N2 is an inert gas, which does not work with food. As a filling gas, N2 is composed of composite fresh-keeping gas with CO2, O2 and special gases. The composition and proportion of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) are different for different food.

The main changes in automated MAP packaging equipment are reducing labor, reducing the possibility of contamination, and making food safer. This is also our goal. MAP packaging of cold meat, using modified atmosphere preservation technology to fill a certain proportion of gas into the package and seal it to isolate fresh meat from the outside world. The mixed gas in the MAP package can inhibit the growth and reproduction of microorganisms and prevent its oxidation. So as to achieve the purpose of extending the shelf life of fresh meat. In addition to keeping the meat fresh, the boxed modified atmosphere packaging can clearly show the meat quality and promote product sales. The MAP packaging seal is strong and easy to tear, which can give customers a high-quality consumption experience.

For modified atmosphere packages (MAP), the natural gas in the packages is replaced by the appropriate gas (Nitrogen, Oxygen, Carbon Dioxide at a certain proportion) for the product. In order to maintain the shape, color and freshness of the product, the air in the modified atmosphere package is replaced by a mixture of gas suitable for the product. This modified atmosphere is usually composed of carbon dioxide, nitrogen and oxygen.
