I. Technical Analysis: Innovative Architecture and Core Advantages of the Peel Making and Powder Equipment

Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory) has been committed to the research and production of grain processing equipment since its establishment in 1951. Its leading products, including peeling and flouring complete sets of equipment, have formed more than a dozen series and over a hundred specifications, covering multiple fields such as flour, beans, mixed grains, and corn. The equipment adopts modular design, achieving efficient processing through an integrated "peeling-grinding-screening" process. The core components such as peeling rollers and flour mills are made of high-strength alloy steel, which improves wear resistance by over 30% and extends the lifespan to twice that of traditional equipment. Taking the corn peeling and germ extraction equipment as an example, it achieves precise separation of germ and skin through a multi-stage air selection system, with a germ extraction rate of up to 92%, a 15% increase over traditional processes, and a 20% reduction in energy consumption.

Part II: Technical Layout: Multi-domain Adaptation and Patent Technology Support

The company's technical layout covers the entire chain of grain processing, from raw material pretreatment to finished product packaging, with independent intellectual property rights. For example, the "film extraction equipment" developed for bean processing adopts low-temperature peeling technology to avoid protein denaturation caused by high temperature, preserving the nutritional components of beans; the deep processing equipment for corn cobs converts corn cobs into high-value-added products such as furfural and xylitol through chemical modification, with a daily processing capacity of up to 50 tons per unit. To date, the company has more than 50 patented technologies, including the "integrated unit for corn polishing, peeling, and embryo extraction" (Patent No.: ZL2020XXXXXXX), which won the provincial science and technology progress award. It achieves an industry-leading level with a peeling rate of 98% and a破碎 rate below 1% through optimizing roller speed and pressure parameters.

Chapter 3: Application Cases: Technology Implementation from Domestic Market to International Export

In an corn processing project in an African country, the "corn peeling-ger extraction-crushing" complete set of equipment provided by Shandong Jinyouliang successfully resolved the issues of high impurity content in local raw materials and low germination utilization rate. The project adopts a "three-level peeling + two-level ger extraction" process, adjusting the gap of the peeling roller (adjustable from 0.5-1.2mm) and the wind selection speed (8-12m/s) to achieve a purity of 95% in the germ, which is directly used for edible oil production, resulting in an annual economic benefit increase of over 2 million US dollars. In China, after a large-scale bean product company introduced the company's "low-temperature bean peeling equipment", the protein content of the product increased by 5%, and there was no wastewater discharge during the peeling process, meeting environmental protection requirements. The equipment has operated for 3 years with a failure rate below 0.5% and a maintenance cost reduced by 40%.

Section 4: Operational Guidelines: Key Parameters for Equipment Commissioning and Maintenance

For flour processing equipment, the following parameters should be paid special attention to during the debugging stage: 1. Milling roller gap: initially set to 0.8mm, gradually adjusted to 0.5-0.6mm according to material particle size; 2. Air classification wind speed: primary screening wind speed controlled at 10-12m/s, secondary screening reduced to 8-10m/s; 3. Roller speed: peeling roller speed 1200-1500r/min, milling roller speed 800-1000r/min. In daily maintenance, it is necessary to check the bearing lubrication every 500 hours, replace the screen every 2000 hours, and regularly clean the dust in the air duct. The company's "Equipment Operation Manual" lists in detail the parameter range and fault code interpretation for each model of equipment, such as the "E03" code indicating motor overload, which requires checking if the material flow exceeds the standard.

V. FAQ: Technical Challenges and Common Questions Answered

Q1: How do peeling equipment adapt to the processing requirements of different raw materials?
A: The company's equipment achieves raw material adaptation through adjustable peeling rollers and wind selection systems. For example, during bean processing, the gap of the peeling roller is adjusted to 0.3-0.5mm, with wind speed at 8-10m/s; for corn processing, the gap is expanded to 0.8-1.2mm, and wind speed is increased to 12-15m/s, ensuring a balance between peeling rate and integrity.

Q2: What international certification standards must equipment exports meet?
Our company has passed the CE safety certification, ISO9001 quality management system certification, and ISO14001 environmental management system certification. The electrical part of the equipment complies with the EU IEC standards, and the mechanical safety meets the EN ISO 12100 standards. It can be directly exported to Europe, Africa, and other regions.

Q3: How to reduce equipment operating energy consumption?
A: By optimizing motor power matching (such as using variable frequency speed control technology) and transmission system design (such as improving belt transmission efficiency to over 95%), the company's equipment achieves a comprehensive energy consumption 15-20% lower than the industry average. For instance, a 50-ton/day flour processing line can save up to 100,000 kWh of electricity annually.
