Record - High Autumn Grain Purchases Nationwide, Surging Storage Demands

According to data released by the National Food and Strategic Reserves Administration, up to now, the cumulative purchase volume of autumn grain nationwide has exceeded 300 million tons, accounting for 60% of the autumn grain output in 2024. As the "main force" of the annual grain output, autumn grain encompasses major varieties such as rice, corn, and soybeans, concentrated in 13 major grain - producing areas including Northeast China, the Huang Huai Hai region, the middle and lower reaches of the Yangtze River, and the southwest region. With the continuous increase in purchase volumes, the demand for high quality grain storage facilities is becoming more urgent. This not only requires an expansion of storage capacity but also sets higher standards for the quality and performance of storage equipment, such as functions in moisture - proofing, heat - insulation, and pest - prevention.

Technological Innovation Empowers the Intelligent Upgrade of Grain Storage

Widespread Application of Intelligent Monitoring Systems

Grain depots in many regions are actively adopting intelligent sensor technologies to conduct real - time monitoring of key indicators such as temperature, humidity, and pest infestation during the grain storage process. The Yinchuan Grain Reserve Depot of Ningxia Grain Group, with the help of the "Smart Ningxia Grain" integrated management platform, transmits data from within the granaries to the management system in real - time through intelligent sensors. Once there are any abnormalities in the parameters, the system immediately issues an alert, and the staff can remotely control and adjust, realizing the intelligent guardianship of grain storage and greatly enhancing the efficiency and accuracy of warehousing management.

The Emergence of Digital Twin and Digital Intelligence Management

The provincial  level rural revitalization grain industry chain in Jiashan, Jiaxing, Zhejiang, adopts the "digital twin digital intelligence management" model to supervise the entire process of rice from warehousing, drying, storage, processing, to sales. Staff can remotely and real time monitor the operation of dryers through the twin system. In the entire base, a small number of staff can complete a large amount of work such as drying, storage, and processing of grain. Technological innovation helps the entire grain industry chain achieve efficient upgrading and iteration.

Promotion of Scientific Grain Storage Methods to Ensure Grain Quality and Safety

During the grain storage process, the application of scientific grain storage methods is crucial for ensuring grain quality and reducing losses. Yihai Kerry (Harbin) Grain and Oil Food Industry Co., Ltd. has shown remarkable practices in granary management. Before April each year, workers carry out "rice husk covering" on the grain surface in the granary, covering a layer of rice husk 20 - 30 centimeters thick, and block the ventilation openings of the silo to block the entry of outdoor air. From May to September, the grain situation is regularly surveyed. By making full use of natural conditions and coordinating the use of equipment such as axial flow fans, grain cooling machines, and centrifugal fans, the granary is ventilated, ventilated, and cooled in a timely manner. This scientific grain storage method basically prevents the breeding of pests and ensures the safety of grain storage. In particular, its innovative combination of the porosity of rice husk (about 65%) and forced ventilation to form an unsteady - state heat and mass transfer model is of exemplary significance in the field of grain storage engineering.

Policy - Driven Standardized Construction of Grain Warehousing

To implement the national food security strategy, local governments are taking active actions. Xuanzhou District, Xuancheng City, has made early plans for grain warehousing. It has comprehensively investigated the existing storage capacity, clarified the goal of optimizing the layout of warehousing facilities by 2030, and plans to phase out some old, small, scattered, and outdated grain storage depots, and upgrade and transform central and key depots to meet the requirements of green and energy  saving grain storage and enhance the risk  resistance ability of grain storage facilities. During the 2024 - 2025 purchase season, the Grain and Strategic Reserves Bureau of Heilongjiang Province took grain purchase and law abiding grain management as key tasks. It continuously organized and carried out services such as policy consultation and information release, strengthened on site management of purchases, and fully organized market - based purchase and sales to ensure the orderly progress of grain purchase and storage work.

Looking to the future, driven by both technological innovation and policy support, the grain storage field will continue to move forward in the directions of intelligence, greenness, and standardization, laying a solid foundation for global food security.
