The vacuum packaging machine is controlled by a microcomputer program, with reasonable structure, stable performance, wide application range, and convenient use and maintenance. The vacuum cover of the vacuum packaging machine is made of stainless steel material in one molding, which is sturdy and reliable and has a long service life. The equipment uses vertical sliding vacuum cover design, stable and reliable operation, and a high degree of product automation.

Main functions of the fried food vacuum packaging machine
The vacuum packaging machine refers to a machine that evacuates the packaged product after the packaging bag contains the product. There are many materials for packaging bags, such as aluminum film and composite materials.
The shape and physical properties of packaging containers are also different. Therefore, the packaging forms and packaging equipment used are also different. In addition to vacuuming and sealing, the food vacuum packaging machine also has the functions of nitrogen filling and coding.
Vacuum inflatable packaging for snacks
The main function of vacuum inflatable packaging is not only the function of deoxidization and quality preservation of vacuum packaging but also the functions of an anti-stress, gas barrier, and freshness, which can effectively maintain the original color, fragrance, taste, shape, and shape of food for a long time.
Many crunchy and fragile foods, foods that are easy to agglomerate, and foods that are easily deformed are not suitable for vacuum packaging and must be vacuum-inflated. After the food is vacuum-inflated, the inflation pressure inside the packaging bag is stronger than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure.
Why choose vacuum packaging for fried foods and snacks?
1. The main function of vacuum packaging is to remove oxygen to prevent food from spoiling. Food mold spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) require oxygen for survival, and vacuum packaging removes the oxygen in the packaging bag and food cells, so that the microorganisms have lost their survival environment.
2. In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum deoxygenation is to prevent food oxidation. Deep-fried foods contain a lot of unsaturated fatty acids, which are oxidized by the action of oxygen, which will make the foods smell and deteriorate.
3. Moreover, oxidation also causes loss of vitamins A and C in food. Therefore, vacuum packaging can effectively prevent food from spoiling and maintain its color, aroma, taste, and nutritional value.
