“ When the timely rain falls and the time of Mangzhong arrives, rice seedlings are planted across the fields. ”， At this time of year, wheat in the north turns golden and is brought into the granaries, while rice seedlings make their debut in the south—bustling with activity and brimming with hope. Also in 。
During the Mangzhong period, summer grain is gradually being stored in granaries, marking a shift in food security from the fields to the warehouses. In this stage, Jiangsu Guoliang Storage Engineering Co., Ltd. plays a crucial role in providing engineering support. As a company specializing in grain storage projects, Guoliang Storage boasts core technologies for steel‑plate grain storage and grain preservation, and integrates systems such as Zhengchang conveying equipment and Zhengchang drying equipment to establish a comprehensive technical service framework for large‑scale storage facilities.
To uphold the century-old mission of Zhengchang—to safeguard the people’s dining tables— ， Drawing on years of research and development in grain storage, Guoliang Warehousing has established a mature, industry‑leading “four-in-one” intelligent grain‑preservation system: grain condition monitoring and control. + Smart Ventilation + Grain Cooling + Airtight grain storage integrates four interdependent technologies into a systematic grain‑preservation solution that spans monitoring to protection, precisely addressing the challenges of mold growth, pest infestation, and aging of stored grain in the rainy, high‑humidity conditions typical of the Mangzhong period.
The grain condition monitoring and control system performs basic monitoring functions. The system is equipped with temperature‑sensing cables, level sensors, and temperature–humidity sensors within the storage facility to continuously collect real-time data on internal grain‑pile temperatures, warehouse humidity, and storage conditions. Should an abnormal temperature rise occur, the system promptly triggers an alarm, providing critical information to guide subsequent operations such as ventilation, cooling, and fumigation.
The intelligent ventilation system can adjust in response to changes in temperature and humidity inside the grain storage facility. When grain temperature rises, internal humidity increases, or localized heat buildup occurs within the grain mass, the system automatically activates fans to draw cool outside air into the facility, facilitating heat and moisture exchange with the grain pile, thereby achieving cooling, dehumidification, and uniform temperature distribution.
Grain cooling systems use grain coolers to deliver cold air—cooler than the ambient temperature—into the storage bin, thereby further reducing the temperature of the grain mass. As the grain temperature drops, its respiration rate decreases, and the reproduction of pests and the activity of microorganisms are also suppressed, helping to minimize storage losses and slow down quality deterioration.
Airtight grain storage addresses protection challenges during long-term storage. A highly airtight silo minimizes the impact of external temperature and humidity fluctuations on the internal environment, while also facilitating operations such as fumigation and controlled-atmosphere storage. For grains requiring extended storage periods, the greater the silo’s airtightness, the more consistent and reliable the effectiveness of pest control, mold prevention, and quality preservation.
Food security is a matter of paramount national importance. Guoliang Warehousing leverages cutting-edge technology to ensure the safe and efficient storage of newly harvested grain, working hand in hand with grain enterprises and farmers across the country to safeguard this year’s bountiful harvest and jointly forge a prosperous future for the grain and oil industry.
