The Development Prospect Of Vacuum Packing Machine

The vacuum packing machine puts the food into the packaging bag, extracts the air in the packaging bag, and completes the sealing process after reaching a predetermined vacuum degree. The main function of vacuum packing is to remove oxygen to help prevent food from spoiling. The principle is also relatively simple. Because food mildew and spoilage are mainly caused by the activities of microorganisms, most microorganisms (such as molds and yeasts) need oxygen to survive. Yes, and vacuum packaging uses this principle to extract the oxygen in the packaging bag and food cells, so that the microscopic objects lose the "survival environment".

The automation of the vacuum packing machine not only improves the production efficiency, but also has the advantages of safety and health. In addition, many foods are not suitable for vacuum packaging and must be vacuum-filled packaging. Such as crispy and fragile foods, foods that are easy to agglomerate, foods that are easy to deform and run out of oil, foods with sharp edges or corners or high hardness that will pierce the packaging bag. After the food is vacuum-inflated, the air 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 without affecting the appearance of the packaging bag and printing decoration.

The vacuum packing machine can effectively keep the freshness and color of fruits and vegetables, and the high concentration of oxygen can keep the fresh meats bright red. In terms of control technology, more computer technology and microelectronic technology are used; in terms of sealing, heat pipe and cold sealing technology are applied; advanced devices are directly installed on the vacuum packing machine, then the development of the vacuum packaging machine is a blueprint!
