Grain storage and preservation is a key link in the grain reserve system. Traditional grain storage mostly relies on chemical fumigation to prevent insects and inhibit bacteria, which easily causes pesticide residues on grain and environmental pollution. Meanwhile, the manual temperature and gas control mode has low accuracy and strong hysteresis, easily leading to grain mildew, insect infestation and aging, resulting in grain loss. With the popularization of green and intelligent grain storage concepts, pesticide-free modified atmosphere grain storage has become the mainstream trend in the industry. The CMS Nitrogen Generator for Grain Storage is a professional nitrogen production equipment developed exclusively for grain storage scenarios with core carbon molecular sieve (CMS) nitrogen production technology. Relying on a complete set of intelligent control systems, it realizes automatic gas production, precise gas regulation, intelligent operation and maintenance, and remote monitoring, completely solving the drawbacks of traditional grain storage nitrogen equipment such as cumbersome manual operation, extensive parameter regulation and serious energy waste, and providing core equipment support for green grain preservation, loss reduction, quality maintenance and intelligent management of granaries.

　　Equipped with core intelligent precise gas conditioning control technology, the equipment adapts to the refined fresh-keeping requirements of grain storage. Based on the mature CMS pressure swing adsorption nitrogen production process and a dedicated intelligent PLC control system, it can automatically match the optimal nitrogen purity, gas production flow and pressure stabilization parameters according to different grain types, storage volume and ambient temperature and humidity of the granary. The equipment can stably output high-purity nitrogen with a purity ranging from 95% to 99.9%, and dynamically adjust the gas production rate through intelligent algorithms. It will automatically enter the pressure and gas stabilization mode when the nitrogen concentration in the granary reaches the standard, accurately maintaining the low-oxygen inert environment inside the granary. This effectively inhibits the respiration of grain, eliminates the survival of mold and pests, and delays grain aging. Different from the extensive operation mode of traditional nitrogen production equipment with fixed parameters, the intelligent dynamic regulation perfectly adapts to the storage requirements of wheat, corn, rice, coarse grains and other grains, avoiding energy waste caused by excessive concentration and fresh-keeping failure caused by insufficient concentration, and greatly improving the stability and professionalism of modified atmosphere grain storage.

　　The all-weather intelligent monitoring and independent protection system is the core intelligent advantage of this special nitrogen production equipment for granaries. Integrated with multi-dimensional intelligent sensor modules, the equipment can collect core data such as oxygen concentration, nitrogen concentration, ambient temperature and humidity, equipment operating pressure and molecular sieve working status in real time for 24 hours, realizing dual intelligent monitoring of grain storage environment and equipment operating status. All operating data is displayed in real time visually, eliminating the need for on-site manual inspection and recording. The system can automatically generate data reports of grain storage gas conditioning, meeting the standardization and traceability management requirements of grain storage. Meanwhile, it is equipped with an intelligent fault self-inspection and linkage protection system. It can provide early warning, automatic shutdown protection and fault prompts for common problems such as pipeline air leakage, abnormal pressure, filter blockage and attenuated molecular sieve working status, avoiding the imbalance of grain storage environment caused by equipment faults from the source and ensuring stable gas supply throughout the year.

　　Intelligent remote operation and maintenance and unattended design greatly reduce the manpower and time costs of granary operation. Traditional grain storage nitrogen production equipment requires full-time staff for on-site start-stop, parameter debugging and regular inspection, resulting in heavy operation and maintenance workload and high labor costs. The CMS Nitrogen Generator for Grain Storage is equipped with an IoT intelligent interconnection module, supporting remote control via mobile phones and computers. Users can remotely start and stop the equipment, view operating data in real time and fine-tune gas conditioning parameters, realizing unattended intelligent operation. In view of the seasonal differences in grain storage, the equipment has an intelligent memory function, which can save gas conditioning parameter schemes for different grain types and switch working conditions with one click without repeated debugging, adapting to various operation scenarios such as rotating grain storage, batch storage and long-term reserve storage. In addition, it has an intelligent energy-saving mode, which automatically adjusts the load power according to the on-demand gas demand of the granary and operates with reduced energy consumption during low-load periods, reducing operating energy consumption by more than 35% compared with traditional equipment and delivering significant long-term energy-saving benefits for grain storage.

　　The intelligent adaptive design tailored for storage scenarios further improves the practicability and durability of the equipment. Considering the characteristics of granaries such as excessive dust and fluctuating ambient humidity, the equipment is equipped with an intelligent dust-proof and moisture-proof adaptive system, which can automatically adjust the operating power of the internal dehumidification module according to ambient humidity, protect the core CMS molecular sieve and electrical components, and extend the service life of the equipment. The integrated intelligent structure requires no complex manual debugging and can operate fully automatically after installation and power-on, adapting to various scenarios such as large-scale grain reserve depots, medium and small granaries and open-air storage tanks. Abandoning the shortcomings of traditional equipment such as complex operation, cumbersome maintenance and poor adaptability, it simplifies the operation process of grain storage gas conditioning through full-process intelligent design, creates a new model of green and intelligent grain storage with no pesticide, zero pollution, low loss and high efficiency, and boosts the digital, intelligent and green upgrading of the grain storage industry.
