World Food Day | Building a Stronger Grain Security Barrier Through Technology

October 16 marks World Food Day.

Food security is closely connected with people’s livelihoods and the stability of the global food system. From fields to dining tables, in addition to grain production, safe storage and efficient circulation are equally essential components in ensuring food security.

The theme of World Food Day 2026 is “Innovate today. Nourish tomorrow.” This year, SRON was invited to participate in the 2026 International Seminar on Post-Harvest Grain Loss Reduction, marking the third time the company has been invited to take part in related exchanges. The seminar focuses on topics including post-harvest grain loss reduction, the development of resilient food systems, and green development. Committed to advancing food security, SRON continues to deepen its expertise in grain storage technologies and engineering practices. Through more reliable grain storage facilities and systematic solutions, SRON contributes to safer grain storage and more efficient grain circulation.

Safeguarding Food Security Starts with Proper Grain Storage

After grain enters storage, factors such as temperature, humidity, pests, and changes in storage conditions can affect grain quality. Modern grain storage facilities must not only meet capacity requirements but also ensure long-term safety and stability.

To address the needs of modern grain storage, SRON has developed integrated solutions covering silos, ventilation, grain condition monitoring, fumigation, conveying, drying, and intelligent control systems. Among these technologies, airtightness serves as a key foundation for maintaining a controllable grain storage environment.

Building a Stable Grain Storage Environment Through Airtightness and Insulation

Airtightness is not simply about sealing the grain silo. It requires systematic sealing of critical areas, including silo walls, roofs, insulation layers, foundation connections, fan interfaces, steel plate joints, and seams.

SRON adopts integrated airtight sealing technology featuring multi-point sealing, multi-layer protection, and overall airtightness enhancement to improve the silo’s sealing performance. Technical indicators of airtight insulated steel silos show that the pressure half-life from 500 Pa to 250 Pa is 5 minutes, meeting the airtightness requirements for grain fumigation and green controlled-atmosphere storage.

Meanwhile, SRON integrates cold-bridge-free insulation technology with airtight sealing technology. Through continuous insulation installation, joint bonding, and staggered double-layer glass wool placement, the impact of thermal bridges is reduced, creating stable conditions for low-temperature and quasi-low-temperature grain storage. Combined with ventilation, grain cooling, recirculating fumigation, and intelligent grain condition monitoring technologies, SRON further enhances the management and control capabilities of the grain storage environment.

From Storage Technology to Engineering Practice, Enhancing Grain Storage Security

The value of technology is ultimately demonstrated through practical engineering applications.

Addressing different grain varieties and storage requirements, SRON continuously optimizes grain storage solutions. In the COFCO 50,000 t soybean steel silo project, eight insulated steel silos form the core storage facilities, with a storage capacity of 6,250 tons per silo. Designed for long-term grain storage needs, the insulated silo structure provides a reliable facility foundation for safe grain preservation.

For materials with specific storage requirements, such as flour, silo design and joint treatment are equally important. For the Mongolia 16 * 200 m³ flour silo project, SRON tailored the silo design to the storage characteristics of flour and adopted an assembled silo structure with welded seam sealing. This approach meets silo airtightness requirements while effectively preventing flour from adhering to the silo walls.

Food security extends beyond storage inside the silo. From receiving and conveying to storage and dispatch, each stage requires seamless integration. In the San Miguel Group project in the Philippines, SRON constructed four 10,000 t flat-bottom steel silos equipped with ventilation, level monitoring, temperature monitoring, ship unloading, conveying, and bulk grain dispatch systems, enabling the silos and supporting equipment to work together as an integrated grain storage and handling solution.

This systematic approach also extends to storage scenarios for different types of commodities. In the Vietnam coffee bean silo project, SRON constructed 12 units of 500 t silos and equipped them with conveying, cleaning, receiving and discharge, packaging, and electrical control systems, meeting the project’s requirements for coffee bean storage and handling operations.

From soybean storage and airtight flour silo design to grain port storage and handling, as well as coffee bean storage, SRON continuously integrates silo design, supporting equipment, and engineering implementation to provide tailored grain storage solutions for diverse application scenarios.

To date, SRON has constructed over 1,000 silos across more than 40 countries and regions worldwide, forming a total storage capacity of over 3 million tons. Each engineering project represents not only storage capacity, but also SRON’s understanding of and response to the specific storage requirements of different materials.

From insulated grain storage and airtight silo design to grain receiving, conveying, and multi-commodity storage applications, SRON continues to apply engineering technologies to various grain storage scenarios.

Food security is a systematic undertaking that requires technical support throughout every stage of storage and handling.

From airtightness and insulation to ventilation, fumigation, and grain condition monitoring, SRON continues to focus on the grain storage sector, providing systematic solutions and engineering practices to support safe grain storage and efficient circulation.

Innovate today. Nourish tomorrow.

SRON will continue to strengthen the foundation of food security through professional grain storage technologies and engineering capabilities.
