60VAC 4BPM Industrial Vacuum Sealing Machine Boxed Fresh Meat Food Sealer SUS304

1. Modified atmosphere packaging is also called gas replacement packaging, and it is called MAP packaging (that is, ModifiedAtmospherePacking) internationally. The principle of the composite modified atmosphere packaging machine is to use composite fresh-keeping gas (2-4 kinds of gases are mixed according to the characteristics of the food) to replace the air in the packaging box or food bag, and change the food environment in the packaging box/food bag. Inhibit the growth and reproduction of bacteria (microorganisms), slow down the metabolism of fresh fruits and vegetables, thereby prolonging the preservation period and use period of food.

2. The fresh-keeping gas is generally composed of carbon dioxide (CO2), nitrogen (N2), oxygen (O2) and a small amount of inert gas. CO2 gas can inhibit the growth and reproduction of most bacteria and molds, and is the main component in the fresh-keeping gas; O2 can inhibit the growth of anaerobic bacteria, can maintain the color of fresh meat, maintain the aerobic respiration required for fresh fruits and vegetables, and keep food fresh Freshness； N2 is an inert gas, which is used as a filling gas to form a composite fresh-keeping gas with CO2, O2 and special gases. Different foods, fruits and vegetables require different components and proportions of fresh-keeping gas.
The difference between vacuum packaging and modified atmosphere packaging
 

1. The vacuum packaging machine automatically seals the packaging bag immediately after pumping it into a low vacuum. Due to the high vacuum in the bag, there is very little remaining air, which effectively inhibits the reproduction of bacteria and other microorganisms, and avoids food oxidation, mildew and Rotting, after vacuum packaging of some soft items, the packaging volume can be reduced, which is convenient for transportation and storage. Vacuum packaging puts the food into the packaging bag, extracts the air from the packaging bag, and completes the sealing process after reaching the predetermined vacuum Packaging is not suitable for fragile food packaging.

2. Modified atmosphere preservation packaging is to put food in a prefabricated box, and exhaust the air in the prefabricated box through a positive pressure system, fill the prefabricated box with the gas in proportion through the mixer, and then seal the prefabricated box, and then seal the prefabricated box. The color and taste of the food will not change, the color of the fresh meat inside will be rosy and elastic, the nutrition in the meat will not be lost, and the food inside will be in a state of sleep, so that nitrogen and carbon dioxide can reach the suppression. The role of bacteria, and oxygen can play a role in keeping fresh, so as to maintain the original flavor of the product, and the appearance of the modified atmosphere packaging is very beautiful, and it will not squeeze the product and fold the appearance like vacuum packaging. The packaging effect is very good.
