The Vacuum Sealing Machine
The vacuum sealing machine is to load food into the packaging bag, extract the air in the packaging bag, and reach the predetermined vacuum degree, then complete the sealing process. Products can also be placed in cartons or buckets and then vacuum packed. For particles, powders, pastes, liquids, and even nano-scale lithium materials, they can be vacuum sealed. Commonly used in vacuum packaging of food materials, medicine, lithium battery powder and other items.
1. The main function of the vacuum sealing machine is to remove oxygen to help prevent food spoilage. The principle is relatively simple, because the food mold spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as mold and yeast) survive Oxygen is needed, and vacuum packaging uses this principle to suck out oxygen in the packaging bag and food cells, so that the microorganisms lose their living environment. The experiment proves that when the oxygen concentration in the packaging bag is ≤1%, the growth and reproduction speed of microorganisms will decrease sharply. When the oxygen concentration is ≤0.5%, most microorganisms will be inhibited and stop breeding. (Note: Vacuum packaging cannot inhibit the deterioration and discoloration of food caused by the proliferation of anaerobic bacteria and enzyme reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt Marinated, etc.)
2. In addition to inhibiting the growth and reproduction of microorganisms, another important function of the vacuum sealing machine is to prevent food from oxidizing. Because oil and fat foods contain a large amount of unsaturated fatty acids, they are oxidized by the action of oxygen, which causes the food to taste and deteriorate. It also causes vitamins A and C to be lost, and unstable substances in food pigments are affected by oxygen, which darkens the color. Therefore, deoxidation can effectively prevent food spoilage.
