Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a continuous automatic vacuum skin packaging machine. Background Technology

[0002] Vacuum packaging machines automatically extract air from packaging bags, achieving a predetermined vacuum level before sealing. They can also be refilled with nitrogen or other mixed gases before sealing. Vacuum packaging machines are commonly used in the food industry because vacuum packaging helps food resist oxidation, thus achieving long-term preservation. Besides inhibiting the growth and reproduction of microorganisms, vacuum deoxygenation also prevents food oxidation. Oily foods contain a large amount of unsaturated fatty acids, which oxidize under the influence of oxygen, causing the food to spoil and change flavor. Furthermore, oxidation leads to the loss of vitamins A and C, and unstable substances in food pigments darken in color under the influence of oxygen. Therefore, deoxygenation effectively prevents food spoilage.

[0003] With the development of technology, a large number of cooked foods can be preserved for a long time through vacuum packaging, which facilitates transportation and sales. Among them, skin vacuum packaging can effectively reduce the volume of finished products and reduce bulk transportation costs. Therefore, skin vacuum packaging machines are widely used in the field of fast food and snacks. However, when using skin vacuum packaging machines to package lighter foods, such as beans or small granules of spicy strips, bulk packaging can easily cause the food to shift, affecting the weight stability of the finished product and leading to inconsistencies in the weight of some finished products.
