What Principles To Follow When Choosing A Vacuum Packing Machine

The main function of vacuum packing machine is to remove oxygen to help prevent food spoilage. The principle is also relatively simple. The food spoilage is mainly caused by the activities of microorganisms, and most microorganisms (such as mold and yeast) need oxygen for their survival. In vacuum packaging, this principle is used to remove the oxygen in the packaging bag and the food cells, so that the microorganisms lose their living environment.

There are many types of vacuum packing machine, and you will inevitably be dazzled when choosing, so the editor summarizes the principles to be followed when choosing a vacuum packaging machine. I hope to help you:
a. Packing speed. For the sake of production efficiency, a double-chamber or multi-chamber vacuum packaging machine can be selected to follow the entire production schedule.
b. Whether the packaged items need to be filled with other protective gases. A multifunctional vacuum packaging machine with an inflation device can be selected.
c. Requirements for vacuum degree of packaged items. If the packaged items need to be kept intact under the condition of vacuum degree, you need to choose the cavity vacuum packaging machine.
d. The requirements of the composition status of the packaged items on the vacuum packing machine.

In addition to inhibiting the growth and reproduction of microorganisms, vacuum packing machine is another important function to prevent the oxidation of food. Because oils and fats contain a large amount of unsaturated fatty acids, they are oxidized by the action of oxygen to make the food smell and deteriorate. In addition, oxidation also makes Vitamins A and C are lost, and unstable substances in food coloring are affected by oxygen, making the color darker. Therefore, oxygen removal can effectively prevent food from spoiling.
