Shandong Jinyouliang Peeling and Flour Milling Equipment Co., Ltd.
I. Company's Technical Background and Industry Status
Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. was originally established as the Shandong Flour Machinery Factory in 1951 and is one of the earliest enterprises in China to engage in the research and development of grain processing equipment. With over 70 years of technical accumulation, the company has formed a full industrial chain technical layout covering wheat cleaning, peeling, flour making, and packaging. The products have passed the ISO9001 quality management system certification and CE international certification, with self-operated import and export rights covering more than 30 countries and regions around the world. Its leading products include intelligent peeling machines, high-efficiency milling machines, and fully automated flour production lines, with technical parameters reaching the advanced level of the industry. For example, the JYL-60 peeling machine developed by the company can achieve a peeling rate of up to 98.5%, with energy consumption reduced by 22% compared to traditional equipment.

Chapter 2: Core Technology Analysis: Integrated Peeling and Flour Production Process
The company's core technology focuses on the deep integration of peeling and flour-making processes. Traditional flour processing requires peeling before flour-making, which involves redundant processes and nutritional loss. JinYouLiang Shandong optimizes equipment structure and process parameters to achieve simultaneous peeling and flour-making: its patented multi-stage roller peeling system (Patent No.: ZL201810567890.2) employs adjustable roller spacing technology, allowing dynamic adjustment of peeling intensity according to wheat varieties, removing over 95% of the bran while ensuring the integrity of the endosperm; the flour-making stage uses an eight-set mill in series process, achieving a flour yield of 78% through precise control of grinding pressure (0.8-1.2MPa) and sieve mesh count (60-120 mesh), controlling ash content below 0.55%, meeting the national special-grade first-class flour standard.
3. Technical Parameters and Equipment Compatibility
Taking the JYL-120 automatic flour production line as an example, this equipment integrates four major modules: cleaning, peeling, flour-making, and packaging, with a processing capacity of 120 tons/day, compatible with voltage of 380V±10%, power requirement of 220kW, and a footprint of only 180㎡. It saves 35% of space compared to traditional production lines. Its core components use imported German bearings (SKF/FAG) and Japanese inverters (Mitsubishi/Analog Devices), ensuring continuous operation stability with a failure rate below 0.3%. To meet different customer requirements, the equipment supports modular customization: for example, it can add a color selection module (accuracy ±0.01mm) or add trace element reinforcement devices to meet the production needs of functional flour.

4. Technical Implementation Case: Flour Mill Upgrade Project in a Certain African Country
In 2022, Shandong Jinyouliang provided a technical upgrade solution for a 50-ton/day flour mill in an African country. The original mill used traditional flour-making technology, which had issues such as low yield (65%) and high energy consumption (75kWh per ton of flour). By introducing a combination of JYL-60 peeling machine and JYL-80 miller, the project achieved three major breakthroughs: 1) The yield was increased to 75%, resulting in an annual increase of 1,800 tons of flour production; 2) The electricity consumption per ton of flour was reduced to 58kWh, saving $120,000 in electricity costs annually; 3) The ash content of the flour was reduced from 0.8% to 0.6%, allowing the product to pass local food certification and increase market selling price by 15%. After the project was accepted, the client placed additional orders for 3 production lines and recommended it to neighboring countries, forming a demonstration effect of technology output.
V. Technological Trend Development and Industry Impact
With the global food processing industry transitioning towards intelligence and greenization, JinYouCang in Shandong continues to increase its R&D investment, with R&D expenses accounting for 6.2% in 2023, higher than the industry average. The company is developing an AI vision detection system that can identify wheat impurities in real-time (with an accuracy of 99.2%), complemented by an IoT module for remote equipment operation and maintenance, expected to be commercialized by 2025. In addition, the national standard "Energy Efficiency Limit Values and Energy Efficiency Grades for Food Processing Equipment" (GB/T 38452-2020), formulated with the company's participation, has been implemented, promoting the standardization of industry technology development. Through dual drives of technological innovation and standard formulation, JinYouCang in Shandong is gradually transforming from an equipment supplier to a food processing solution service provider.
