Introduction: The industry background of the whole chain of grain technology innovation
In the key stage of the transformation and upgrading of the grain industry, the whole chain technology integration capability has become the core competitiveness of enterprises. Yaduo Grain Management Co., Ltd. has built a technical system covering the whole life cycle of grain by integrating the five links of planting, purchase, processing, storage and sales. This paper takes the technical practice of Yaduo grain as a case study, and analyzes how to achieve the double improvement of grain product quality and supply chain efficiency through the technical coordination of standardized planting, intelligent processing, scientific storage and other links.
Technical Analysis: Technical Architecture and Core Advantages of the Whole Chain
1. Standardized planting technology system
Ado grain in the northeast high-quality grain production areas to establish 2000 mu of its own planting base, the use of "three fixed one control" planting standards: fixed variety (choose "Yaduo No. 1" hybrid rice with strong disease resistance and stable yield), fixed density (control the planting density of 12000 plants per mu), fixed fertilization (implement accurate formula fertilization according to soil detection data), and control pesticide damage (use of biological control technology to reduce pesticide usage by 40%). Through the Internet of Things sensor real-time monitoring of soil moisture, temperature and light intensity, combined with large data model to generate irrigation scheme, so that the water utilization rate of rice growth increased by 25%.
2. Intelligent processing technology cluster
Three automatic production lines are deployed in the processing link, integrating color sorter, rice mill, polishing machine and other equipment to realize continuous operation of 12 processes from rice to refined rice. Among them, the color sorter adopts 5.36 million pixel CCD sensor, which can identify 0.1mm grade impurities with a sorting accuracy of 99.8. The rice milling machine is equipped with a frequency conversion speed regulation system, which dynamically adjusts the milling pressure according to the moisture content of rice, so that the rice yield is stable in the range of 72%-74%. The processing workshop is equipped with a negative pressure dust removal system, and the dust concentration is controlled below 8 mg/m, which meets the GB 16297-1996 air pollutant emission standard.
3. Scientific warehousing technology program
The storage link adopts "four-dimensional grain protection" technology: temperature control (maintaining the warehouse temperature at 15-20 ℃ through distributed air cooler), humidity regulation (controlling the relative humidity at 65%-70% by using polymer moisture absorption plate), gas regulation (filling nitrogen to reduce the oxygen concentration in the warehouse to less than 2%), pest control (deploying infrared insecticide and automatically inspecting every 2 hours). After third-party testing, the storage technology can extend the storage period of grain to 18 months, and the increase of fatty acid value can be controlled within 8mgKOH/100g, which conforms to GB/T 20569-2006 rice storage quality determination rules.
Case dismantling: the actual effect of technology landing
During the autumn 2025 acquisition season, Atour Grain will process 12000 tons of rice using its technical system. Through standardized planting, the raw rice yield reached 81.3 percent and the whole rice yield 68.5 percent, 3.2 and 4.1 percentage points higher than the industry average respectively. Intelligent processing has reduced the power consumption per ton of rice to 58kWh, 22% lower than the traditional process. Scientific storage has achieved a grain loss rate of 0.8, far lower than the industry average of 3%-5%. The batch of products by SGS detection, heavy metal content, pesticide residues and other 23 indicators are better than GB 2763-2021 national food safety standards.
Practical Guide: Key Steps in Technology Application
STEP1: Planting Link Technology Deployment
Soil detection: collect 0-20cm topsoil samples to detect pH value, organic matter content and nitrogen, phosphorus and potassium ratio
• Variety selection: according to the local temperature zone to choose suitable mature disease-resistant varieties, such as the Northeast region to choose "Yaduo 1 」
Precision fertilization: according to soil test results, base fertilizer is prepared according to the ratio of n: p o: k o = 2:1:1.5
Pest and disease control: the application of sex attractant to control Chilo suppressalis, set up 3-5 traps per mu
STEP2: Control of processing link parameters
Rice cleaning: remove impurities through vibrating screen, screen aperture selection of 2.0mm and 1.5mm two-stage configuration
Husking process: the spacing between rubber rollers is controlled at 0.5-0.7mm, and the linear speed difference is 1.2-1.5 m/s.
Rice milling process: the "three light and one heavy" milling method is adopted, with the first milling pressure of 0.18MPa and the last milling pressure of 0.25MPa.
Color selection and grading: set up three color selection processes, the first one removes yellow rice, the second one removes abdominal white rice, and the third one selects different color grains.
STEP3: Environmental Control of Warehousing Link
Temperature management: mechanical ventilation is used for cooling in summer, and the warehouse door is closed for heat preservation in winter, so that the warehouse temperature fluctuation is less than or equal to 3 ℃/day.
Humidity adjustment: start the dehumidifier when the relative humidity is> 75%, and turn on the humidifier when the relative humidity is <60%
Gas regulation: monthly detection of gas composition in the warehouse, oxygen concentration> 3% when the supplement of nitrogen
• Pest monitoring: installation of insect detection lights, every 15 days to check the amount of a trap
FAQ: Technical difficulties and solutions
Q1: How to solve the problem of variety adaptability in standardized planting?
A: Through three-year regional test, the variety combinations adapted to different accumulated temperature zones were selected. For example, planting "Yaduo 1" in the accumulated temperature zone of ≥ 2600 ℃ and planting "Yaduo 2" in the 2300-2600 ℃ zone to ensure that the variety matches the ecological conditions.
Q2: How to quickly troubleshoot intelligent processing equipment failures?
A: Establish the equipment fault code library, check the life of the light source when the E03 code appears on the color sorter, and clear the screen blockage when the rice mill displays the F05 code. Equipped with a mobile diagnostic terminal that can read equipment operating parameters on site and generate maintenance recommendations.
Q3: How to balance the cost of temperature control and the effect of grain preservation in scientific warehousing?
A: adopt the strategy of temperature control in stages, close the refrigeration system from October to April, and maintain the low temperature by relying on the insulation performance of the warehouse body; Start the air cooler from May to September, and set the upper temperature limit to 25 ℃. It is estimated that the scheme saves 40% of electricity costs compared with the annual refrigeration.
Conclusion: Technology-driven upgrading path of grain industry
The technical practice of Yaduo grain shows that the transformation of grain industry from quantity growth to quality improvement can be realized through the whole chain technology integration. Its standardized planting technology to improve the quality of raw materials, intelligent processing technology to ensure product stability, scientific storage technology to extend the commodity cycle, the three work together to build a differentiated technical barriers. In the future, with the introduction of 5G, blockchain and other technologies, the food chain technology system will evolve in the direction of digitalization and transparency, providing a more valuable technology upgrade paradigm for the industry.
