Shandong Jinyouliang Peeling and Flour Milling Equipment Co., Ltd.
Technical Background: The Leap from Traditional Flour Milling to Intelligent Processing
Shandong JinYouLiang Peel Removal and Flour Milling Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory) has been dedicated to the research and manufacturing of grain processing equipment since its establishment in 1951. Its leading products cover peeling and flour-making complete sets, with over ten series and more than a hundred specifications. The application fields have expanded from flour processing to beans, mixed grains, corn, food, brewing, and many other industries. The company has obtained ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and CE Safety Certification, ensuring the entire process from design to production is standardized, providing a solid guarantee for technical implementation.

Technical Analysis: Core Advantages Driven by Patents
The company's technological layout is centered around "energy-saving, environmental protection, and efficiency," successfully developing multiple patented technologies. For example, the dehulling and film extraction equipment for beans adopts a low-temperature dehulling process, achieving a dehulling rate of over 98% by optimizing the roller speed (300-500 rpm) and sieve aperture (0.5-2mm), while reducing the breakage rate of the bean kernel to below 2%, significantly improving the powder yield. The corn polishing and dehulling equipment for germ extraction achieves precise separation of corn germ and skin through multi-stage polishing and wind selection systems, with a germ extraction rate of 95%, suitable for the starch and oil extraction stages in the corn deep-processing industry chain.
In terms of intelligent control, the company's intelligent control system can monitor equipment operating parameters (such as current, temperature, and speed) in real-time and achieve remote fault diagnosis through the Internet of Things module. For instance, after a flour mill applied its intelligent flour-making equipment, the electricity consumption per ton of flour dropped from 65 degrees to 58 degrees, saving over 200,000 yuan in annual electricity bills, while the equipment fault response time was shortened to within 30 minutes, and production efficiency was improved by 15%.
Practical Case: Full-process Support from Equipment Selection to Process Optimization
Taking an African corn processing project as an example, the client needs to process corn into high-precision corn flour (fineness 80-120 mesh) while extracting corn germ for edible oil production. Shandong Jinyouliang, based on the characteristics of the raw materials (corn moisture content 14%-16%) and process requirements, has customized an integrated solution of "peeling-polishing-extracting germ-making flour".
Step 1: Equipment Selection
Choose the corn专用peeling machine (model JYL-TP500) with adjustable roller gap (0.8-1.5mm) and double-layer screen, suitable for different particle size corn; the配套dehulling machine (model JYL-TE300) uses vacuum wind selection technology, achieving a germ separation efficiency of 92%.
STEP 2: Process Adjustment
In the initial peeling stage, adjust the roller speed to 400 rpm to stabilize the peeling rate at 96%; in the embryo extraction stage, optimize the air selection speed to 12 m/s, increasing the purity of the germ to 98%, meeting the production standards for edible oil.
STEP 3: Energy Efficiency Optimization
During the flour-making process, a graded grinding technique is adopted, reducing the motor power of the mill from 30kW to 22kW. At the same time, the intelligent control system dynamically adjusts the roller spacing, lowering the electricity consumption per ton of flour to 55 degrees, achieving a 15% energy-saving compared to the traditional process.

Technical Adaptation: Differentiated Solutions for Various Industry Scenarios
Shandong Jinyouliang's equipment technology is not a "one-size-fits-all" approach but offers customized solutions tailored to different industry needs. For instance, in the field of bean processing, adjustable peeling machines have been developed to address the hardness and skin-removing difficulty of different beans such as soybeans, mung beans, and peas. By replacing different materials of the roller (rubber or stainless steel) and screen (nylon or metal), a balance between peeling rate and breakage rate is achieved. In the field of mixed grain processing, for small-sized grains like buckwheat and oats, the air selection parameters of the cleaner machine have been optimized (wind speed 8-10m/s), resulting in a 99% removal rate of impurities and an 8% increase in flour yield.
FAQ: Technical Challenges and Common Issues Solutions
Q1: How does the peeling equipment adapt to raw materials with different moisture contents?
A: The company's equipment is equipped with a moisture detection module, which can monitor the moisture content of raw materials in real-time (range 10%-20%) and automatically adjust the roller gap and peeling time through the PLC control system. For example, corn with 14% moisture requires adjusting the roller gap to 1.2mm and extending the peeling time to 3 minutes to ensure a stable peeling rate.
Q2: How is the data security of the intelligent control system ensured?
Equipment uses encrypted communication protocols (such as MQTT), with data transmission encrypted using AES-256, while also supporting local storage and cloud backup to ensure production data is not lost or leaked. Users can set access permissions for different levels of operators through the permission management feature, preventing data risks caused by accidental operations.
Summary: Industry Upgrade Path Driven by Technology
Shandong Jinyouliang's technical practice shows that the upgrade of grain processing equipment should be centered around "demand-oriented," achieving a leap from single equipment to an overall solution through patent technology breakthroughs, process optimization, and intelligent control. Its equipment's advantages in energy saving (reduction of 10%-15% in ton powder electricity consumption), environmental protection (dust emission ≤10mg/m³), and efficiency (12%-18% increase in production efficiency) have been verified in 30 provinces and cities across the country as well as in overseas markets such as Europe and Africa, providing a replicable technical paradigm for the high-quality development of the grain processing industry.
