PSA nitrogen generator for food preservation and transportation
Principle: During food transportation, nitrogen can be used as an inert gas to effectively prevent food oxidation, mildew and pest breeding. NEWTEK PSA nitrogen generator can produce high-purity nitrogen on site, and its principle is to use pressure swing adsorption technology. Under a certain pressure, nitrogen in the air is adsorbed by the adsorbent, and then the nitrogen is desorbed by decompression to obtain nitrogen with higher purity.
Case: For example, in the transportation of fresh fruits, such as strawberries, blueberries and other perishable fruits, filling nitrogen in the transport container can reduce the oxygen content, slow down the respiration of the fruit, and extend the shelf life. Packing strawberries in a nitrogen-filled modified atmosphere packaging bag can extend its shelf life from 1-2 days to about 5-7 days at normal ambient temperature, greatly reducing the loss during transportation. At the same time, for some processed foods that need to be transported over long distances, such as potato chips and nuts, filling with nitrogen can also prevent the food from being crushed, because nitrogen plays a buffering role.
PSA nitrogen plant is used for the transportation of chemical products
Principle: Many chemical products are flammable, explosive or oxidizable. Nitrogen, as a gas with stable chemical properties, can play a role in safety protection in the transportation of chemical products. The nitrogen produced by PSA nitrogen production equipment can provide an inert environment for chemical products and reduce the risk of chemical reactions.
Case: Taking the transportation of liquid organic chemicals as an example, chemical products such as styrene, which are easy to polymerize, are prone to polymerization reactions if they come into contact with active substances such as oxygen during transportation, resulting in a decrease in product quality and even causing danger. By filling nitrogen into the transport tank, replacing the air in the tank, and placing styrene under nitrogen protection, the occurrence of polymerization reactions can be effectively prevented. In addition, for the transportation of some flammable and explosive gas mixtures, such as hydrogen and oxygen mixtures, nitrogen is pre-filled into the transportation pipeline for purging to remove air and impurities in the pipeline, and then the mixed gas is transported, which can significantly reduce the risk of explosion.
PSA O2 generator is used for the transportation of electronic components
Principle: Electronic components have high requirements for the environment. Factors such as humidity and oxygen content may affect the performance and quality of electronic components. Nitrogen can effectively control the humidity and oxygen content in the transportation environment and provide a dry, oxygen-free transportation environment for electronic components. The nitrogen produced by NEWTEKPSA industrial nitrogen production equipment has high purity and can meet the strict requirements for the transportation of electronic components.
Case: During the transportation of semiconductor chips, the chips are easily corroded by moisture and oxygen in the air. Placing the chip in a sealed transport container filled with nitrogen, the moisture content in the nitrogen is extremely low (usually controlled at a very low ppm level), which can prevent the chip from getting damp, and the oxygen-free environment also avoids the oxidation of the metal pins of the chip. This ensures that the performance of the chip is not affected during transportation, which is crucial to ensuring the quality and reliability of electronic products.
PSA nitrogen plant is used in the transportation of cultural relics
Principle: Cultural relics, especially organic cultural relics such as paper, wood, and silk, are easily damaged by environmental factors, such as oxidation and mildew. Nitrogen can create a stable, oxygen-free transportation environment for cultural relics, slowing down the aging and damage process of cultural relics. PSA N2 equipment can provide a suitable nitrogen environment according to the specific needs of cultural relics transportation.
Case: For example, ancient calligraphy and painting have extremely high environmental requirements during transportation. Place the calligraphy and painting in an airtight box filled with nitrogen. The nitrogen in the box can prevent the fading of the painting pigments and the aging of the paper. Some wooden cultural relics unearthed by archaeology, such as thousand-year-old coffins, can also be protected by nitrogen during transportation. By filling the transport container with nitrogen and reducing the oxygen content, it can effectively prevent the decay and insect infestation of wooden cultural relics, which is of great significance for the long-term preservation and safe transportation of cultural relics.
