1. technology layout: the whole chain of grain processing technology system

Based on high-quality grain production areas, Yaduo Grain Management Co., Ltd. has built a full-chain technical system covering planting, acquisition, processing, storage and sales. In the planting process, the company uses intelligent monitoring system to collect soil temperature and humidity, light intensity and other parameters in real time, combined with the Internet of Things technology to achieve precision irrigation and fertilization. For example, 500 soil sensors deployed in the core production area of Zhaoyuan County can transmit data to the cloud platform to generate fertilization recommendations through AI algorithms, increasing corn yield by 12%.

2. acquisition link: multi-parameter detection technology to ensure the quality of raw materials

The company's self-developed grain purchase detection system integrates moisture meter, bulk density device, imperfect grain analyzer and other equipment, which can simultaneously detect 12 quality indicators. Taking corn acquisition as an example, the system can complete the detection of key parameters such as moisture (accuracy of 0.5%) and impurity content (accuracy of 0.2%) within 30 seconds, and the detection efficiency is 3 times higher than that of traditional methods. The system has been applied to 20 acquisition sites in the three northeastern provinces, and has detected more than 500000 batches of grain samples.

3. processing link: low temperature finishing technology to retain nutrition

The Swiss Bühler low-temperature rice milling equipment introduced by the company controls the rice processing temperature below 65°C through a multi-stage light milling process, which is 20°C lower than traditional equipment. After testing, the process can increase the retention rate of vitamin B1 in rice to 85%, and the amylose content is stable in the range of 18%-20%. At present, the technology has been applied to the daily processing of 300 tons of rice production line, the product through the SGS nutrition retention certification.

4. storage link: intelligent temperature control technology to extend the shelf life

The company's self-developed intelligent storage system uses a distributed temperature sensor network to monitor the internal temperature changes in the grain pile in real time. When the local temperature exceeds 25 ℃, the system automatically starts the nitrogen gas conditioning device to reduce the oxygen concentration to less than 2%, effectively inhibiting insect pests and mildew. Data from the application of the 100000-ton storage base in Zhaoyuan County show that the technology has reduced the grain storage loss rate from 3 per cent to 0.8 per cent and extended the shelf life to 24 months.

5. sales link: blockchain traceability technology to build trust.

The food traceability platform developed by the company integrates more than 200 items of data in planting, processing, storage and other links. Consumers can view the whole life cycle information by scanning the packaging QR code. Taking "Yaduo Jinsui" rice as an example, the traceability system records the transportation track, processing time, quality inspection report and other key data from the planting base to the processing plant in Zhaoyuan County, realizing the transparency of "from field to table. The platform has been connected to the national agricultural product quality and safety traceability management information platform, and has generated more than 20 million traceability codes.

6. technical parameters and industry adaptation

1. Intelligent planting system: sensor accuracy ± 0.1 ℃, data transmission delay <1 second, suitable for major producing areas such as northeast black soil area and Huang-Huai-Hai Plain
2. Acquisition detection system: detection cycle of 30 seconds/batch, support corn, rice, wheat and other 6 kinds of grain detection
3. Low temperature processing equipment: processing temperature 65 ℃ 2 ℃, capacity range 10-500 tons/day
4. Intelligent storage system: temperature control accuracy of ± 0.5 ℃, single warehouse capacity of up to 50000 tons
5. Traceability platform: data storage cycle of 10 years, support 100000 query requests per day

7. typical application cases

In the acquisition of corn in the fall of 2025, the company applied an intelligent detection system to grade the quality of 30000 tons of corn in the Jianxanjiang production area of Heilongjiang Province. The system automatically divides five grades through parameters such as bulk density (≥ 720g/L) and moisture (≤ 14.5), so as to increase the proportion of high-quality grain from 65% to 82% of the traditional grade and help cooperative farmers increase their income by 12 million yuan. The case was selected as a "typical application scenario of digital agriculture" by the Ministry of agriculture and rural areas ".

8. Technology Iteration Direction

The company plans to invest 20 million yuan in 2026 to develop grain molecular marker detection technology, through DNA fingerprinting to achieve variety purity identification, is expected to shorten the variety identification time from 7 days to 24 hours. At the same time, the impurity sorting equipment based on machine vision is being tested, which can identify small impurities above 0.3mm, with a sorting accuracy of 99.5%.
