Technological Accumulation: A seventy-year craft inheritance honed over time

Shandong Jinyouliang Peeling and Flour Milling Equipment Co., Ltd. (formerly known as Shandong Flour Machinery Factory established in 1951) is one of the earliest domestic enterprises engaging in the research and development of grain processing equipment. Its flour machine production base, after more than 70 years of technological iterations, has developed over a hundred models of equipment across more than ten series, covering peeling, flour making, and intelligent control, with an annual production capacity exceeding 5,000 sets. The company has obtained certifications for ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System, ensuring standardized control throughout the entire process from raw material procurement to finished product delivery.

Technological Breakthrough: Patent-driven Equipment Upgrade Path

In core equipment research and development, the company focuses on two major directions: energy-saving and environmental protection, as well as efficiency enhancement. For example, its corn polishing and peeling equipment adopts a two-stage cyclone separation technology, which can increase the corn germ extraction rate to over 92%, reducing energy consumption by 30% compared to traditional equipment. The dehulling and film extraction equipment for beans utilizes a dynamic pressure regulation system to achieve a dehulling rate of 98% while maintaining the integrity of the beans, suitable for processing over 20 types of beans such as peas and chickpeas. As of 2023, the company has accumulated 12 invention patents and 45 utility model patents, including the "Intelligent Control Flour Mill" patent technology (Patent No.: ZL202110XXXXXX.X), which optimizes production parameters in real-time through a PLC control system, increasing the flour yield by 5 percentage points.

Industry Applications: From grain processing to cross-industry technology extension

The company's technological layout is not limited to the traditional flour processing field. In the chemical industry, the deep-processing equipment for corn cob developed by the company, through the high-temperature hydrolysis process, can convert corn cob into high-value-added products such as furfural and xylitol, with a daily processing capacity of up to 15 tons per unit; in the mining industry, the wear-resistant powder mill developed for ore crushing needs, using a high-chromium alloy hammer head combined with a grading screen, extends the service life of the equipment to 2.3 times that of the traditional model. These cross-industry application cases demonstrate the scalability of the company's technical platform – through modular design, the same core power system can be adapted to material processing needs in different industries.

Technical Management: International Certification and Continuous Improvement Mechanism

The company establishes a trinity management system of "Technology-Production-Service": the R&D department invests 8% of annual revenue in new technology research, the production workshop implements the "6S" on-site management standard, and the after-sales service team covers 32 provincial-level administrative regions across the country. Taking the 500 tons/day wheat flouring equipment set for export to Russia as an example, the project team optimized the equipment lubrication system and motor protection level through simulation tests in the Siberian low-temperature environment, ensuring stable operation of the equipment at -30℃. This case is included in the company's "Manual for Equipment Adaptability Improvement in Extreme Environments" and serves as a technical reference for subsequent market expansion in the Nordic region.

Future Outlook: Dual Drive of Intelligence and Greening

Faced with the trend of intelligent transformation in the grain processing industry, enterprises are advancing the construction of "digital twin factories" by embedding Internet of Things sensors in equipment to achieve real-time collection of production data and cloud optimization of process parameters. At the same time, their new-generation flour mill adopts permanent magnet synchronous motors and variable frequency speed regulation technology, reducing the electricity consumption per unit output to 0.035 kW·h/kg, a decrease of 18% compared to the industry average. These technological upgrades will help enterprises move towards the goal of "zero-carbon factories" and provide a replicable green solution for the global grain processing industry.
