Technical Background and Industry Status

Shandong JinYouLiang Peel Milling Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory) has been focusing on the research and production of complete sets of grain processing equipment since its establishment in 1951. As one of the early enterprises in China to obtain ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System certifications, its products cover more than ten fields such as flour, beans, mixed grains, and corn, forming a matrix of over a hundred specifications of equipment. Currently, the company owns a number of patented technologies, with its products exported to Europe, Africa, Russia, South Korea, and other regions, becoming an important driver for technological upgrading in the grain processing industry.

Technical Architecture Analysis: The Leap from Traditional to Intelligent

The company's leading products are designed with a core concept of "energy-saving, environmental protection, and high efficiency," and have established a multi-level technical architecture.

1. Integrated Peel and Powder TechnologyBy optimizing the roller spacing (adjustable from 0.5-2mm) and the wind selection system parameters (wind speed 8-12m/s), the peeling rate of beans, corn, and other raw materials reaches ≥98%, while energy consumption is reduced by 15%. For example, the corn polishing and peeling equipment adopts a two-stage cyclone separation technology, which can simultaneously extract corn germ (purity ≥90%), meeting the dual needs of food processing and oil extraction.

2. Intelligent Control SystemIntegrated PLC automation modules and IoT sensors for real-time monitoring of equipment operation status (such as temperature and vibration frequency). Taking a complete set of flour processing equipment as an example, the system can automatically adjust the grinding pressure (0.2-0.5MPa) and sieve mesh count (60-120 mesh), ensuring the flour yield remains stable between 75%-82%.

3. Modular designThe main equipment adopts standardized components (such as motor power ranging from 5.5 to 37kW), supporting quick disassembly and functional expansion. For example, its grain processing equipment can complete the switching from buckwheat to sorghum processing mode within 2 hours by replacing the sieve and mill head.

Typical Application Case: Corn Cob Deep Processing Project Implementation

In a cooperative project with a large corn processing enterprise, Shandong Jinyouliang provided a complete set of deep processing equipment for corn cores, achieving the following technological breakthroughs:

1. Raw material adaptability optimizationFor fluctuating moisture content in corn cobs (10%-18%), the equipment is equipped with a humidity sensor and an automatic drying module to ensure processing stability.

2. Multi-stage separation technologyThrough three-stage cyclone separation and pulse dust removal system, the products after corn cob crushing are graded by particle size (0.1-2mm) for use in furfural extraction, biomass fuel preparation, and feed additive production.

3. Energy Efficiency ManagementAdopting variable frequency drive technology, the comprehensive energy consumption of the equipment is reduced to 0.08 kW·h/kg (the industry average is 0.12 kW·h/kg), with a daily throughput of 50 tons per line.

After one year of operation, the customer feedback indicates that the equipment failure rate is below 2%, the product pass rate has increased to 99.3%, and through the comprehensive utilization of by-products, the annual income has exceeded 2 million yuan.

Technical Layout and Future Direction

The company continuously invests in R&D resources, focusing on two major fields:

1. Green manufacturing technologyDevelop low-noise (≤75dB) and low-dust (emission concentration ≤10mg/m³) equipment, meeting the EU CE safety standards.

2. AI-powered processing optimizationCollaborate with universities to develop a machine learning-based raw material quality prediction model, which automatically generates the optimal processing technology plan by analyzing parameters such as raw material hardness and protein content.

Currently, Shandong Jinyouliang has formed a competitive advantage with "patented technology + customized services + global supply chain," and its equipment has been verified in the grain processing industries of over 30 countries, providing a replicable solution for the industry's technical upgrade.
