When using a high-purity PSA nitrogen generator for grain, how can you ensure that the stored grain is not affected by harmful impurities or moisture?

The high-purity PSA nitrogen generator for grain uses pressure swing adsorption (PSA) technology to extract high-purity nitrogen from the air through selective adsorption of adsorbents such as high-quality imported carbon molecular sieves. The equipment can stably provide 99.99% pure nitrogen, ensuring that the nitrogen contains almost no oxygen, moisture and other harmful impurities. The generator is equipped with an advanced monitoring system that can monitor the purity and flow of nitrogen in real time. Once the purity drops or the flow is abnormal, the equipment will automatically adjust the operating parameters to ensure that the purity and supply of nitrogen always remain within the set range.
Before grain storage, high-purity nitrogen should be injected into the storage bin in the prescribed proportion. At the same time, it is necessary to ensure that the storage bin has good airtightness to prevent external air from infiltrating. All holes (including roofs, basements, vents, etc.) should be sealed to ensure a closed environment for nitrogen. In actual operation, the final oxygen content in the bin should be set according to the type of stored grain and storage conditions. By regularly monitoring the oxygen content in the warehouse and replenishing nitrogen in time, it can be ensured that the oxygen content in the warehouse is always controlled within a safe range, thereby effectively inhibiting the respiration and microbial activity of grains.
In order to ensure the long-term stable operation of the grain high-purity PSA nitrogen generator and the high purity of nitrogen, the equipment needs to be maintained and calibrated regularly. This includes checking and replacing key components such as filters and adsorbents, as well as cleaning and lubricating other parts of the equipment. Operators should receive professional training and be familiar with the working principle of the nitrogen generator, the nitrogen delivery operating procedures, and the use of safety protection equipment. During operation, the operating procedures should be strictly followed to ensure the correct operation and safe use of the equipment.
Before storing grain in nitrogen, the grain can also be dried to reduce its moisture content. This helps to further reduce the risk of mildew and fermentation of grains during storage. During storage, the state of the grain in the storage bin should be checked regularly, and impurities and dust should be cleaned in time to keep the storage environment clean and hygienic.
