A nozzle-type gas flushing and sealing machine is a device used in packaging operations to remove air or modify the gas composition inside a package and then seal it. This process is commonly used in the food industry to extend the shelf life of perishable products by creating a modified atmosphere within the package.

Here's how the machine typically works:

1.       Package Placement: The operator places the product to be packaged inside the machine. This can be a tray, pouch, or any other type of container suitable for the product.

2.       Gas Flushing: The machine is equipped with one or more nozzles that introduce a specific gas or gas mixture into the package. The most commonly used gases are nitrogen, carbon dioxide. The choice of gas depends on the specific requirements of the product and its shelf life. Nitrogen is often used to displace oxygen and create an oxygen-free environment, which slows down the deterioration of many food products. Carbon dioxide is used as a preservative and to inhibit the growth of spoilage-causing microorganisms.

3.       Sealing: Once the desired gas composition is achieved inside the package, the machine seals the package to maintain the modified atmosphere. The sealing mechanism can vary depending on the machine design and the type of package being used. Common sealing methods include heat sealing, impulse sealing, or ultrasonic sealing.

4.       Product Removal: After sealing, the operator removes the sealed package from the machine, and it is ready for labelling and distribution.

Gas flushing and sealing machines are commonly used in industries such as food packaging, pharmaceuticals, electronics, and other sectors where the preservation of products is critical. These machines offer benefits such as extended shelf life, improved product presentation, and reduced spoilage.
