I. Corporate Technical Strength and Historical Development

Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory, established in 1951) is a senior enterprise in the field of grain processing equipment in China. With over 70 years of technical accumulation, it has developed into a comprehensive enterprise integrating research and development, production, and sales. The company has established a full-process standardized system covering design, production, and service through ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, ISO45001:2018 Occupational Health and Safety Management System, and CE safety certification, providing dual guarantees for technical stability and product safety.

II. Technical Layout of Lead Products and Core Advantages

The company's leading products include complete sets of peeling and flour-making equipment, forming more than ten series and over a hundred specifications of grain processing machinery, which meet the needs of various fields such as flour, beans, mixed grains, corn, rice milling, food, brewing, oil, starch, chemical industry, mining, and intelligent control. Its technical advantages are reflected in three aspects:

1. Patented technology drives innovationThe equipment for dehulling and film extraction of beans, corn polishing and hulling, and deep processing of corn cores holds multiple patents. By optimizing the dehulling process and embryo extraction efficiency, the raw material utilization rate is increased by 15%-20% and energy consumption is reduced by 12%-18%. For example, the corn dehulling and embryo extraction equipment uses a two-stage dehulling + intelligent sorting technology, which can accurately separate the germ from the hull, achieving a germ integrity rate of over 98%, meeting the production requirements of high-end corn oil.

2. Energy-saving and environmentally friendly design conceptThe equipment development adheres to the principles of "simplification, efficiency, energy-saving, and environmental protection". By optimizing the transmission structure and the wind selection system, dust emissions are reduced by over 30%, and noise is controlled below 75 decibels, meeting the EU CE safety standards. Taking a 50-ton/day flour processing line as an example, its unit energy consumption is 18% lower than that of traditional equipment, saving over 100,000 yuan in electricity costs annually.

3. Multi-domain adaptabilityEquipment supports modular assembly, allowing process parameters to be adjusted according to the characteristics of different raw materials (such as bean hardness, corn moisture content). For example, in the processing of high-starch corn, by adjusting the grinding gap and sieve mesh count, the starch extraction rate can be increased to 92%, while retaining the dietary fiber in the corn skin, meeting the requirements for food-grade raw materials.

3. Technical Implementation Case: Review of the African Corn Processing Project

In 2022, Shandong Jinyouliang provided a complete processing equipment for a certain African country, capable of processing 200 tons of corn per day, covering the entire process of peeling, embryo extraction, crushing, and packaging. The technical team customized the equipment parameters in response to the local corn's characteristics of high moisture content (18%-22%) and high impurities.

1. Pre-processing OptimizationBefore peeling, add two additional cleaning and drying processes to reduce the corn moisture content to 14%-16%, thereby decreasing the breakage rate during the peeling process.

2. Process parameter adjustmentThe drum speed of the peeling machine is adjusted from 450 rpm to 380 rpm, extending the stay time of corn in the peeling chamber, and improving the peeling rate to 99%.

3. Intelligent Control System IntegrationMonitor the equipment's operating status in real-time through the PLC control panel, automatically adjust the grinding pressure and sieve mesh count, ensuring the fineness (80-120 mesh) and stability of the powder output.

After the project was implemented, the customer reported stable equipment operation, a 10% increase in corn flour yield, a 15% increase in germ extraction, and an annual increase of over $500,000. Currently, the equipment has been running stably for 3 years with a failure rate below 2%, and has received high recognition from the customer.

4. Summary of Technical Experience and Future Planning

Shandong Jinyouliang's technical success originates from three aspects of experience: Firstly, adhering to "demand-oriented" research and development, regularly visiting Europe for study and learning, introducing advanced technology, and localizing it; secondly, constructing a collaborative system of "industry-academia-research-application," cooperating with multiple universities to carry out research on grain processing technologies; thirdly, strengthening "full lifecycle service," providing one-stop support from equipment selection, installation and debugging to after-sales maintenance.

In the future, the company plans to further expand into the intelligent control field, develop an Internet of Things-based remote monitoring system, achieve real-time collection of equipment operation data and fault warnings, and assist the grain processing industry in transforming towards digitalization and intelligence.
