Product Description: Background of Nitrogen Filling Technology:  In the early 21st century, the United Nations Food and Agriculture Organization (FAO) has imposed further restrictions and bans on the use of fumigants during the storage of grains and oils. It actively advocates for modifying the storage environment of pests and molds by adjusting the gas composition within grain piles (controlled atmosphere storage), reducing the aerobic respiration of the grains themselves. This approach aims to achieve safe grain storage, delay aging, and realize green grain storage. With the improvement in people's living standards, there is increasing emphasis on the hygiene indicators of grains. The promotion and application of nitrogen-based grain storage equipment can fully meet the demand for green food and is becoming the preferred new technology for green grain storage in China.Introduction to the Dedicated Nitrogen Generation System for Green Grain Storage:  The green grain storage nitrogen generation series products launched by Hangzhou Lecheng effectively achieve the goal of green grain storage. The generated nitrogen is delivered to the storage facility with specific purity, pressure, temperature, and flow rate. Through the gas distribution pipelines in the storage, the nitrogen is evenly diffused within the grain pile. As the concentration gradually increases and is maintained for a certain period, it disrupts the survival environment of pests and molds, causing pests to suffocate and die, inhibiting the physiological respiration of grains, delaying grain aging, and ensuring storage quality. The promotion and application of nitrogen-based controlled atmosphere grain storage.Advantages of the Grain Storage Nitrogen Generation SystemSystem Energy Efficiency Advocate—New energy-saving technology consumes only 75% of the energy compared to similar products.Extensive Engineering Case StudiesRich Experience in Supporting Grain Storage Technologies—Over a decade of engineering experience in the green grain storage industry.Ideal and Reliable Performance—No negative records since 2007.Fully Intelligent Control—One-click startup, remote monitoring, multifunctional comprehensive alarm system.High-Quality System ConfigurationProcess Flow of the Grain Storage Nitrogen GeneratorThe nitrogen generation system mainly consists of three parts: air compression, air purification, and nitrogen-oxygen separation and delivery.Air is compressed by the compressor to 7.0-8.5 Bar. It then passes through the three-stage filter, refrigerated dryer, and activated carbon oil remover in the purification system to remove most of the moisture, oil, and particulate impurities, providing a safer air source for the subsequent nitrogen generation host.The air enters the two adsorption towers of the nitrogen generation host. The towers are filled with high-performance carbon molecular sieves specifically designed for oxygen adsorption. Based on their different "selective adsorption" of nitrogen and oxygen in the air under pressure, the automatic switching of valves enables the two towers to undergo a pressure swing adsorption (PSA) process of "pressurized adsorption and depressurized desorption." Specifically, under pressure, the molecular sieve adsorbs oxygen while allowing nitrogen to pass through, which is then collected and delivered. When adsorption saturation is reached, the system automatically switches to the other tower for pressurized adsorption, while the current tower is depressurized to release the adsorbed oxygen. This alternating process continuously produces high-purity nitrogen.Some Technical Parameters of the Grain Storage Nitrogen GeneratorNitrogen Flow Rate: 1-6000 m³/hrNitrogen Purity: 95%-99.5% (100% minus oxygen content)Atmospheric Dew Point: ≤ -45°CNitrogen Pressure: 0.05~6 Bar, adjustableApplicable Environment: Temperature -15～35°C, Humidity more>
