I. Technical Background and Industry Status

Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory, established in 1951) is a comprehensive enterprise specializing in the research and production of complete sets of grain processing equipment. It holds self-operated import and export rights and has certifications for ISO9001:2015, ISO14001:2015, ISO45001:2018 management systems and CE safety certification. Its leading products cover peeling and flouring complete sets, with more than ten series and over a hundred specifications, widely used in the fields of flour, beans, mixed grains, corn, rice milling, food, brewing, oil and fat, starch, chemicals, mining, and intelligent control. The products are exported to international markets including Europe, Africa, Russia, and South Korea.

II. Technical Principle and Core Advantages

1. Integrated skinning and powder making technology
The dedusting and powdering complete equipment developed by our company adopts the "dedusting first, then powdering" process. By combining multi-stage dedusting rollers with a wind selection system, it effectively removes the grain skin (such as corn hulls, legume seed coats) while retaining the germ and nutritional ingredients, and simultaneously reducing the impurity content in the powdering process. For example, the corn dedusting and germ extraction equipment can achieve a dedusting rate ≥98% and germ integrity rate ≥95%, significantly improving the quality of the powder.
2. Energy-saving and environmental protection design concept
The equipment utilizes low-energy consumption motors (power range 3-30kW) and variable-frequency control technology, saving 20%-30% more energy than traditional equipment; equipped with a pulse dust removal system, dust emission concentration ≤10mg/m³, in compliance with national environmental protection standards. Taking the bean peeling equipment as an example, its daily processing capacity per unit can reach 20 tons, with energy consumption of only 15kW·h/ton.
3. Intelligent Control System
Integrated PLC automatic control and sensor monitoring technology allows for real-time adjustment of parameters such as peeling gap and wind selection speed, ensuring processing stability. For example, corn cob deep-processing equipment uses an intelligent temperature control system to keep the drying temperature error within ±2℃, avoiding material scorching.

Chapter 3: Analysis of Typical Application Cases

1. Case 1: Corn Deep Processing Project
An African enterprise has introduced the complete set of corn polishing and peeling equipment (model JYL-TP50) from Shandong Jinyouliang, for the production of corn grits and corn germ oil. Project parameters are as follows:
Processing capacity: 50 tons/day
- Peel efficiency: 99.2%
- Germination extraction rate: 96.5%
Energy-saving effect: 35% more energy-efficient than local traditional equipment
After the project was implemented, the customer reported stable equipment operation, a 40% increase in product value-added, which helped them enter the high-end European market.

2. Case 2: Dehulling of Beans and Film Extraction Project
A domestic food company uses the JYL-DP30豆类脱皮 equipment (suitable for soybeans, peas, etc.), combined with the film extraction process, to produce high-protein soy skin feed. Technical specifications:
- Peel Time: ≤3 minutes/batch
- Protein retention rate: ≥92%
- Film thickness: adjustable from 0.5-2mm
After project implementation, customers save over 2 million yuan in raw material costs annually, and the products have passed the EU Organic Certification.

4. Technical Layout and Future Direction

Shandong Jinyouliang continues to invest in R&D, with the focus on technological upgrades in the past three years including:
- Develop specialized peeling equipment for niche grains (such as quinoa, chickpeas).
Optimize the intelligent control system, enabling remote monitoring and fault early warning.
- Explore the utilization of biomass energy, converting waste materials into clean fuel.
The company's technical director said: "We design with the principles of 'simplistic, efficient, energy-saving, and environmentally friendly,' meeting the diverse needs of global customers through technological innovation."

Fifth, FAQ Technical Questions

Q1: What range of grains is suitable for the peeling and flour-making equipment?
A: The equipment can process over 30 types of grains such as wheat, corn, soybeans, peas, sorghum, and buckwheat, and requires adjusting the roller spacing and air selection parameters according to the material characteristics.

Q2: How to select the equipment model?
A: Consider the daily processing capacity (5-200 tons/day available), energy consumption requirements (standard/energy-saving model), and automation level (semi-automatic/full automatic), as the company offers customized solutions.

Q3: What is the maintenance cycle for the equipment?
Suggested inspection of the descaling roller wear after every 500 hours of operation, oil change every 2000 hours, and filter core of the pulse dust collector should be cleaned or replaced annually.
