1. Technology Architecture: Digital Control of the Whole Chain from Field to Table

Yaduo Grain Management Co., Ltd. has built a digital technology system covering the five links of planting, purchase, processing, storage and sales. At the planting end, the company uses IoT sensors to monitor soil moisture, temperature and nutrient content in real time, and combines satellite remote sensing technology to generate farmland health maps to guide precision fertilization and irrigation. For example, in the 10,000-mu corn planting base in Zhaoyuan County, Heilongjiang, the intelligent irrigation system has increased the utilization rate of water resources by 40% and reduced the use of chemical fertilizers by 25%.

2. processing link: intelligent sorting and quality control technology

The company introduced the intelligent color sorter of Bühler Group in Germany, equipped with high-precision CCD camera and AI image recognition algorithm, which can identify and eliminate mildew and moth-eaten particles in real time, with a sorting accuracy of 99.97%. In the rice processing line, through multi-stage milling process and laser impurity removal technology, the rice crushing rate is controlled within 1.2, which is far lower than the industry standard of 3%. The intelligent packaging line put into operation in 2025 adopts a visual inspection system, which can automatically identify the sealing defects of packaging bags, and the defect detection rate is 80% higher than that of artificial.

3. warehouse management: low-temperature quasi-low-temperature grain storage technology system

The company's self-developed intelligent storage system integrates temperature sensors, gas concentration monitors and ventilation control modules, which can realize layered monitoring of grain pile temperature and precise temperature control. In the 50000-ton bungalow warehouse, the grain temperature is stabilized in the range of 15-20 ℃ by internal circulation temperature control technology, and the mortality rate of stored grain pests is 98%, and the grain preservation period is extended to 3 years. The newly built vertical silo group in 2026 adopts distributed ventilation system, and the energy consumption of single silo is 35% lower than that of traditional silo type.

4. Quality Traceability: Blockchain Enabling Food Safety Transparency

Yaduo Grain has established a quality traceability platform based on block chain, which stores more than 200 key indicators such as grower information, agricultural input records, processing batch data, storage environment parameters, etc. Consumers can view the whole process information of grain from sowing to sales by scanning the two-dimensional code of packaging, including pesticide use time, processing equipment number, storage temperature and humidity curve, etc. The system has passed the ISO 22000 food safety management system certification, data retention cycle up to 10 years.

5. Technology Layout: Industry-University-Research Collaborative Innovation Mechanism

The company and the School of Food of Jiangnan University jointly established a joint laboratory for food processing, focusing on whole grain nutrition retention technology, and successfully developed a brown rice processing technology that retains 92% dietary fiber. In the field of storage, the intelligent ventilation controller developed in cooperation with the Chengdu Food Science Research Institute of China Grain Storage can automatically adjust the air volume according to the heat transfer model of the grain pile, reducing the ventilation energy consumption by 40%. Of the 8 utility model patents obtained in 2025, 4 are related to the optimization of low-temperature grain storage equipment.

6. Application Case: Technical Practice of Serving Large Grain and Oil Enterprises

In a customized solution for a central enterprise grain and oil group, Yaduo Grain shortened the grain storage inspection time from 72 hours to 8 hours by deploying intelligent sampling equipment and rapid testing laboratories. The system integrates near-infrared spectrometer and heavy metal rapid detector, which can simultaneously complete the detection of 12 indicators such as moisture, protein, aflatoxin, etc., and the detection data is automatically uploaded to the customer's ERP system to realize seamless connection of the supply chain.

7. technical parameters: core equipment performance indicators

1. Intelligent color sorter: processing capacity 8 tons/hour, color sorting accuracy 99.97, take-out ratio 1:1.2
2. Low-temperature quasi-low-temperature warehouse: temperature control accuracy 0.5 ℃, nitrogen concentration ≥ 98%, single warehouse capacity 5000 tons
3. Block chain traceability system: data chain delay <0.5 seconds, supporting 1000 query requests per second
4. Intelligent ventilation controller: air volume adjustment range 0-5000m ³/h, control accuracy 5%

8. Technology Advantage: Analysis of Three Core Competitiveness

1. Full-chain data penetration: breaking the data island of planting, processing and warehousing to achieve pre-control of quality risks
2. Precise environmental control: through the Internet of Things and AI algorithm to build a grain pile microenvironment adjustment model, grain storage loss rate control within 1%.
3. Rapid response capability: relying on the national layout of 12 regional testing centers, can achieve 48 hours to complete the quality of cross-provincial re-inspection

Impact of 9. industry: promoting technological upgrading of grain industry

Yaduo Grain's technical system has served more than 200 grain and oil enterprises in 32 provincial administrative regions across the country, helping customers to reduce operating costs by an average of 18% and raise the qualified rate of products to 99.6. The group standard of "intelligent granary construction standard" led by the company has been incorporated into the key promotion project of the "14th Five-Year Plan" of the State Grain and Material Reserve Bureau.

10. Future Outlook: Blueprint for Intelligent Grain Ecological Construction

In 2026-2028, the company will invest 0.12 billion yuan to build an Internet platform for the grain industry to integrate the capacity data of 1000 upstream and downstream partners. Focus on the research and development of digital twin-based intelligent storage system, through the virtual granary to simulate the effect of grain storage under different climatic conditions, to achieve preventive maintenance decision-making. At the same time, the layout of grain carbon footprint accounting technology, to help the industry to achieve the "double carbon" goal.
