I. Technical Background and Industry Status

Shandong Jinyouliang Peel-off and Flour Milling Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory) was established in 1951 and is one of the earliest enterprises in China engaged in the research and development of grain processing equipment. 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, as well as the "CE" safety certification. Its products cover more than ten series and over a hundred specifications of peeling and flour-making complete sets of equipment, which are exported to Europe, Africa, Russia, South Korea, and other regions. The company's technological layout is centered around "sophistication, efficiency, energy saving, and environmental protection," forming a comprehensive solution covering flour, beans, mixed grains, corn, and other fields through the continuous introduction of advanced European technology and independent research and development.

Section 2: Core Technology Analysis of Flour Milling Machines

1. Integrated peeling and powder-making technologyThe peeling and flouring complete equipment developed by our company uses the "peeling first then flouring" process, achieving an efficient separation of the grain skin and endosperm in wheat, corn, and other grains through multi-stage sieving and air selection systems. For instance, its 6FT-30 flour mill has a processing capacity of 30 tons per day, with a peeling rate ≥98% and a flour yield 15% higher than traditional equipment, while reducing energy consumption by 20%.

2. Application of Intelligent Control SystemThe equipment is equipped with a PLC intelligent control module, which can monitor parameters such as grinding gap and feeding speed in real-time and achieve remote control through a touch screen. Taking the 8FT-50 intelligent flour mill as an example, its control accuracy reaches ±0.01mm, and the fault self-diagnosis function can shorten downtime by more than 30%.

3. Energy-saving and environmentally friendly designBy optimizing motor power matching and air flow circulation system, the equipment operation noise is ≤75dB, dust emission concentration is ≤10mg/m³, meeting national environmental protection standards. For example, its corn peeling and germ extraction equipment adopts double-stage cyclone dust removal technology, achieving a dust collection efficiency of 99.5%.

Section 3: Typical Application Cases: Peeling Equipment for Beans and Film Extraction Equipment

1. Project BackgroundA soybean product processing enterprise needs to improve the efficiency of soybean peeling and recover the soybean hulls (soybean seed coat). Traditional equipment has issues such as incomplete peeling and low recovery rate of soybean hulls.

2. Technical SolutionShandong Jinyouliang offers DT-20 type bean peeling machine, using the "wet peeling + air flow sorting" process. By adjusting water temperature (50-60℃) and peeling time (3-5 minutes), it achieves a peeling rate ≥99% and film recovery rate ≥95%. The equipment is equipped with 304 stainless steel grinding roller, which has 3 times higher wear resistance than ordinary materials.

3. On-the-ground effectAfter the project implementation, the company's daily soybean processing capacity increased from 15 tons to 20 tons, the film recycling cost was reduced by 40%, and the product added value increased by 25%. The equipment has obtained a national utility model patent (Patent No.: ZL2020XXXXXXX.X).

4. Technical Advantages and Industry Compatibility

1. Multi-domain coverage capabilityThe equipment supports the processing of raw materials such as wheat, corn, beans, and mixed grains. By replacing the screens and mill rolls, it can adapt to materials of different particle sizes. For example, the mixed grain processing equipment can handle hard grains like buckwheat and oat, with a flour fineness of 80-120 mesh.

2. Modular Design: Standardized modular assembly for complete sets of equipment, allowing flexible configuration of peeling, grinding, packaging, etc. according to customer requirements, reducing the project delivery period by over 30%.

3. Global Service Network: The company has established 12 service centers overseas, offering equipment installation and debugging, operation training, and spare parts supply services to ensure the stability of equipment operation throughout its entire lifecycle.
