A nitrogen filling machine is a device used to fill nitrogen gas inside packages or containers.
Nitrogen is a stable, inert gas that makes up approximately 78% of the Earth's atmosphere. Its inert properties prevent oxidation and deterioration when used to replace oxygen in packaging, thereby extending the shelf life of food products and pharmaceuticals. By filling packaging with nitrogen, the freshness of products is preserved for longer periods.
Nitrogen filling machines use high-pressure nitrogen or liquid nitrogen cylinders to apply pressure and seal nitrogen into containers. The nitrogen gas pressure and flow rate are precisely controlled by a microcomputer, PLC, or other control devices. Many machines are equipped with pressure relief valves and overpressure prevention devices to ensure the safe handling of liquefied nitrogen or high-pressure nitrogen. This process helps prevent oxidation and maintains product quality over time.
Nitrogen filling machines are primarily used to prevent oxidation by eliminating oxygen from packaging. Common applications include:
Nitrogen filling is widely used in food packaging to eliminate oxygen and prevent oxidation, thereby preserving product quality and freshness. Common examples include snacks, coffee beans, and dried fruits.
Nitrogen filling machines are also used for packaging frozen foods, which are often stored and consumed over long periods. The nitrogen filling prevents oxidation and deterioration in the frozen state, maintaining the quality of the product for extended periods. Additionally, nitrogen is used in packaging for products like wine and whiskey, whose flavors can be altered by oxidation.
Nitrogen filling is also employed for moisture-sensitive products, such as semiconductor components and electronic equipment. During transportation, nitrogen gas is often used to fill the packaging atmosphere to prevent damage or deterioration. Nitrogen packaging may also offer protection against physical shock and vibration. In some cases, nitrogen filling machines are used for precision instruments, such as high-end watches, to prevent deterioration caused by oxidation and moisture.
Nitrogen filling machines are commonly used in the packaging of pharmaceuticals, particularly those containing ingredients that are prone to oxidation, such as vitamins and antibiotics. By filling the packaging with nitrogen, the oxygen is eliminated, preventing oxidation reactions and preserving the active ingredients for an extended shelf life. This ensures that the efficacy of the drug is maintained for a longer period.
