Technical Background and Industry Position

Shandong Jinyouliang Peeling and Flouring 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 earliest enterprises in China to obtain independent import and export rights, its products cover more than ten fields such as flour, beans, mixed grains, corn, and have formed a matrix of over a hundred specifications of equipment. The company has passed the ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System certifications, and obtained CE safety certification, with technical standards aligned with international standards.

Core Technology Analysis: Energy-saving, Environmental Protection, and Intelligent Upgrade

The company adheres to the design philosophy of "sophistication, efficiency, energy-saving, and environmental protection," integrating multiple patented technologies in peeling and powder-making equipment. For instance, the developed bean peeling and film extraction equipment utilizes low-temperature physical peeling technology, raising the peeling efficiency to over 98% while preserving the nutritional components of the beans; the corn polishing and peeling equipment achieves precise separation of corn germ and bran powder through multi-stage screening and air separation technology, with a germ integrity rate of up to 95%, suitable for starch and oil extraction stages in the corn deep-processing industry chain. Additionally, the company's intelligent control system can monitor equipment operating parameters in real-time, automatically adjusting processing intensity based on raw material humidity and particle size, achieving energy savings of 20%-30% compared to traditional equipment.

Typical Application Scenarios and Technical Parameters

In the flour processing industry, Jin You Liang's complete flour-making equipment supports the full automation of wheat cleaning, conditioning, grinding, and sieving processes. Taking the FM-200 flour-making unit as an example, it has a processing capacity of 100-120 tons/day, equipped with 6 groups of millers and 8 sieving systems, achieving a flour yield of up to 75% and fineness in compliance with GB1355-2021 standards. The equipment is suitable for a voltage of 380V, with a power of 180kW, occupying an area of approximately 120㎡ and is suitable for the scaled production needs of medium-sized flour mills. In the processing of mixed grains, its multi-functional peeling machine can handle buckwheat, oat, sorghum, and other raw materials. By adjusting the roller spacing and speed (500-800r/min), it can achieve precise peeling of mixed grains of different particle sizes, with a stable peeling rate above 92%.

Technology Layout and Globalization Practice

The company continuously invests in R&D resources, travels to Europe to learn advanced manufacturing technologies, and optimizes equipment structure based on domestic market demands. For example, its corn cob deep-processing equipment, by introducing German airflow crushing technology, grinds corn cob to a fineness of 200-300 mesh, used in the production of xylitol, furfural, and other chemical raw materials, with an annual processing capacity of up to 50,000 tons. Abroad, Jinyouliang's equipment has been exported to over 30 countries including Europe, Africa, Russia, and South Korea. The mobile powder production units developed for the African market (processing capacity of 20-30 tons/day), driven by diesel engines, meet the needs of power-deficient areas and are widely used in rural cooperatives in countries like Nigeria and Kenya.

FAQ: Technical Challenges and Solutions

Q1: How to balance the peeling efficiency and raw material loss of grain processing equipment?
A: Jinyouang reduces frictional loss between raw materials and equipment by optimizing the material and surface treatment of the peeling roller (such as using high-chromium alloy spraying), and at the same time, sets up a multi-level air selection system within the peeling chamber to timely separate the peeled layers, preventing raw material breakage caused by repeated processing.

Q2: How does an intelligent control system enhance equipment stability?
A: The system's built-in sensor network can collect over 20 parameters in real-time, such as motor temperature, vibration frequency, and material flow, and analyze data anomalies through the edge computing module. When the bearing temperature of the mill exceeds 80℃, the system automatically reduces the speed and activates the cooling device to prevent equipment overheating and shutdown.

Q3: How do export equipment meet the standard requirements of different countries?
A: Jinyouliang targets the EU market by incorporating explosion-proof motors, safety interlock devices, and other configurations in equipment design, obtaining CE certification. For the African market, it simplifies the electrical control system, using a distribution box with IP65 waterproof and dustproof ratings to adapt to high temperature and humidity environments.
