What Are The Classifications Of Vacuum Packaging Machines?

        What is a vacuum packaging machine?

        After the vacuum packaging machine reaches the preset vacuum degree, it can automatically extract the air in the packaging bag to complete the sealing process. Or it can be filled with nitrogen or other mixed gas again, and then complete the sealing process. Vacuum packaging machines are often used in the food industry, because after vacuum packaging, food can resist oxidation, so as to achieve the purpose of long-term preservation.

        The working principle of the vacuum packaging machine.

        The vacuum packaging machine is composed of a vacuum system, a suction sealing system, a hot pressing sealing system and an electrical control system. External vacuum packaging machines are designed to automatically seal the bag as soon as it is drawn into a low vacuum. For some soft foods, after packaging with an automatic vacuum packaging machine, the packaging volume can be reduced, which is convenient for transportation and storage. The principle of the desktop vacuum packaging machine is to use plastic composite film or plastic aluminum foil composite film as packaging material to vacuum pack or vacuum solid, liquid, powdery and pasty food, chemicals, electronic components and rare metals, etc. Package.

        Application of vacuum packaging machine. 

        1.Vacuum packaging machines can obtain packaging with consistent specifications according to the requirements of the packaged goods and the required shape and size, but manual packaging cannot be guaranteed. This is especially important for exporting goods. Only vacuum-packed products can realize the standardization of packaging and meet the requirements of collective packaging.

        2.Operations that cannot be achieved by manual packaging can be realized. Some packaging operations can only be achieved by vacuum packaging, which cannot be achieved by manual packaging.

        3.It can reduce labor intensity and improve working conditions. Manual packaging is labor intensive. For example, manual packaging of bulky and heavy products is labor-intensive and unsafe; for light and small products, workers are prone to occupational diseases due to high frequency and monotonous movements.

        4.Conducive to the labor protection of workers. For some products that seriously affect health, such as dusty and toxic products, as well as irritating and radioactive products, artificial packaging will inevitably endanger health, while mechanical packaging can be avoided and can protect the environment from pollution.

        Classification of vacuum packaging machines.

        1.Food vacuum packaging machine.

        This kind of packaging machine needs to control the temperature before vacuum packaging, and the equipment has its own cooling system, so the requirements for freshness preservation are relatively high.

        2.Medical vacuum packaging machine.

        This kind of packaging machine should have a vacuum pumping form that can preserve the product for a long time; since the medical packaging machine should be used in places with high requirements such as dust-free and aseptic workshops, this type of vacuum packaging machine can also be applied to food packaging with aseptic requirements , and achieved good results.

        3.Vacuum packaging machine for electronic products.

        The use of vacuum packaging machines for electronic products can prevent oxidation and discoloration of moisture and internal metal products.

        4.Tea vacuum packaging machine.

        This is a machine integrating weighing, outer packaging and inner packaging. The birth of the vacuum tea packaging machine marks a big step forward in the level of tea packaging in my country and realizes the standardization of tea packaging.
