I. Technical Background and Industry Status

Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory, established in 1951) is a comprehensive enterprise specializing in the research and manufacturing of complete sets of grain processing equipment, with independent import and export rights. 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, and has also obtained the "CE" safety certification. Its leading products cover more than ten series and over a hundred specifications of peeling and flouring equipment, widely used in the fields of flour, beans, mixed grains, corn, corn cobs, rice milling, food, brewing, oil and fat, starch, chemicals, mining, and intelligent control, with products exported to countries such as Europe, Africa, Russia, and South Korea.

II. Core Technology and Patent Layout

The company adheres to the design philosophy of "sophistication, efficiency, energy-saving, and environmental protection" and continuously improves equipment technology. For example, the dehulling and film extraction equipment developed by the company uses patented technology, achieving a dehulling rate of ≥98% while reducing the particle breakage rate to ≤1.5% through optimizing the dehulling roller gap (adjustable from 0.5-2mm) and the speed ratio (1:2.5-3.2). The corn polishing, dehulling, and germ extraction equipment utilizes a multi-stage polishing process (3-5 levels selectable) and a negative pressure suction system (airflow 5000-8000m³/h), effectively removing surface impurities from corn and enhancing the purity of germ extraction to over 95%. In addition, the deep-processing equipment for corn cobs converts them into high-value-added products such as xylose raw materials (conversion rate ≥85%) and furfural (extraction rate ≥70%) through high-temperature and high-pressure hydrolysis technology (temperature 180-220°C, pressure 1.5-2.0MPa).

3. Typical Application Cases and Technical Effects

In a European flour processing project, the 6FT-50 type flour-making equipment provided by Shandong Jinyouliang achieves a wheat flour yield of 78% (meeting the national standard for first-grade flour) through a combination of five skin grinding systems and eight core grinding systems. The electricity consumption per ton of flour is reduced to 58kWh, saving 15% of energy compared to traditional equipment. In terms of equipment operation stability, the main shaft uses SKF imported bearings (life ≥ 50,000 hours) and is matched with an intelligent control system (PLC + touch screen), which can monitor the roller spacing of the mill (accuracy ±0.01mm) and feeding amount (range 100-1000kg/h) in real-time, ensuring that the fluctuation of process parameters during processing is ≤2%.

4. Technical Upgrade and International Cooperation

The company regularly conducts inspections in Europe to study advanced equipment and technology, such as introducing Germany's dynamic balancing technology for flour millers (residual unbalance ≤0.5g·mm/kg) and Italy's air distribution optimization scheme for flour cleaners (wind speed uniformity ≥90%), and integrates these with domestic raw material characteristics (e.g., wheat hardness index 50-80) for localized improvements. The 50 tons/day corn processing equipment exported to Africa, designed with modularization (single module size ≤3m×2m×2.5m) and quick-install interfaces (installation time reduced by 40%), adapts to local infrastructure conditions and achieves rapid production.

V. Summary of Technical Advantages

Shandong Jinyouliang's technical advantages are reflected in three aspects: Firstly, the patented technology covers core processes (such as peeling, flour making, and deep processing), forming a technical barrier; secondly, the equipment parameters have a wide adjustable range (such as roller spacing, air volume, and temperature), adapting to different raw materials and processing requirements; thirdly, the energy-saving and environmentally friendly design (indicators such as ton powder electricity consumption and particle rate are better than industry standards), in line with the global green transformation trend of the grain processing industry. Through continuous technological innovation and international cooperation, the company is gradually moving from domestic leadership to the global technical competition ranks.
