Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging, in particular to a food vacuum packaging device. Background Art

[0002] Food vacuum packaging is to put food into packaging bags, extract the air in the packaging bags, and complete the sealing process after reaching a predetermined vacuum degree. In the food industry, vacuum packaging is very common. For example, when producing food products such as duck feet and duck wings, the main function of food vacuum packaging is to deoxygenate, which is beneficial to prevent food spoilage. The principle is relatively simple, because food mold and spoilage are mainly caused by the activities of microorganisms, and most microorganisms (such as molds and yeasts) need oxygen to survive. Vacuum packaging uses this principle to extract the oxygen in the packaging bags and food cells, depriving the microorganisms of their living environment. Therefore, vacuum-packed food has a long shelf life, greatly extending the shelf life of food.

[0003] However, the depth of the vacuum chamber in some food vacuum packaging machines is fixed. When vacuuming different foods, due to the vacuum chamber being too deep or too shallow, it is very easy for the packaging bags to move or slide when vacuum packaging bags of different sizes, resulting in poor vacuum effect. Therefore, those skilled in the art provide a food vacuum packaging device to solve the problems raised in the above background technology. Utility Model Content
