Technical Accumulation: The Leap from Traditional Machinery to Intelligent Flour Milling

Shandong Jinyouliang Peeling and Flour Milling Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory) has been dedicated to the field of grain processing since its establishment in 1951. It has gradually transformed from a traditional flour machinery manufacturer to a comprehensive enterprise integrating the research and development of peeling, flour-making complete sets of equipment. Its technological layout covers more than ten fields such as flour, beans, mixed grains, corn, etc., forming a product matrix of over a hundred specifications to meet diverse needs from small-scale workshops to large-scale industrial production lines. For example, its corn polishing peeling and germ extracting equipment, through multi-level screening and air separation technology, can improve the processing accuracy of corn to over 98%, increase the flour yield by 15% compared to traditional technology, and reduce energy consumption by 20%.

Technical Principle: Fusion of Modular Design and Energy-saving and Environment-friendly Practices

The company's core equipment adopts a modular architectural design. Taking the peeling and flouring integrated machine as an example, its technical process is divided into four stages: pretreatment, peeling, grinding, and sieving. The pretreatment stage adjusts the roller spacing (0.5-3mm adjustable) through frequency conversion to accommodate different particle size raw materials; the peeling section uses a double-screw extrusion technology, achieving a peeling rate of 99.2% while preserving the integrity of the germ; the grinding system is equipped with a dynamic compensation device that can automatically adjust the grinding roller gap (0.02-0.1mm) according to the material humidity, ensuring uniformity of the flour output; the sieving module uses a multi-layer vibrating sieve (3-5 layers optional), with the fineness modulus precisely controlled within the range of 0.8-2.5. This design enables a single machine to process up to 50-200 tons per day, a 40% increase in efficiency compared to traditional equipment, and dust emission concentration lower than 10mg/m³, in compliance with the EU CE safety standards.

Application Cases: Technical Validation from Domestic Market to International Layout

In an African country's grain processing project, the corn deep-processing equipment provided by Shandong Jinyou Grain achieves full-process automation from raw material cleaning to starch extraction. The project utilizes its patented corn cob deep-processing module, converting corn cobs into xylitol raw materials through high-temperature and high-pressure hydrolysis technology. The annual production capacity of a single line reaches 3,000 tons, with product purity up to 99.5%, and the products are directly exported to the European market. Additionally, in the Siberian region of Russia, its bean peeling equipment maintains stable operation at -30℃ low temperature, with a peeling rate of 98.7% and a failure rate below 0.5%, earning the customer's "zero downtime" evaluation.

Technical Certification: Quality Assurance System under International Standards

The company has obtained the triple certification of ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System. All products are equipped with CE safety marking. In the testing phase, each equipment must undergo a 72-hour continuous operation test, including no-load, full-load, and overload (110% rated load) conditions. The vibration value is controlled at ≤2.5mm/s, noise ≤85dB(A), and bearing temperature ≤65°C. For example, the flour mill exported to South Korea has been tested on-site by the customer, showing that the electricity consumption per ton of flour is only 68kWh, 12% more energy-efficient than local similar products, and the ash content of the flour is below 0.55%, meeting the standard of high-end bread flour.

FAQ: Common Questions on Flour Mill Customization Technology

Q1: How to choose a suitable flour mill model for small-scale processing?
A: For small-scale processing (daily capacity ≤ 10 tons), it is recommended to choose single-machine integrated equipment, such as the FM-50 type peeling and flouring machine from Shandong Jinyouliang, which occupies only 15㎡ of space and is equipped with a 30kW motor. It can achieve integrated operations of wheat cleaning, peeling, and grinding, and the fineness of the flour can be flexibly adjusted by changing the screen (80-120 mesh).

Q2: What is the maintenance cycle and replacement standard for key components of the flour mill?
A: Daily maintenance requires cleaning the screen (to prevent clogging) every day, checking the belt tension (looseness ≤5mm) weekly, and lubricating the bearings monthly (using NLGI 2 lithium grease). Key components such as the grinding roller have a lifespan of about 5000 hours, and they need to be replaced when the particle size deviation is >10% or the surface wear depth is >0.5mm. The screen replacement cycle is 2000 hours, with the standard for determining the screen hole deformation rate being >5%.

Q3: How to achieve energy-saving optimization in flour processing?
A: Can be optimized from three dimensions: Firstly, using variable frequency drive technology (such as the Siemens variable frequency drive standardly equipped in Shandong Jinyouliang equipment), automatically adjust the grinding roller speed (adjustable from 500 to 1500 rpm) based on the moisture content of the raw materials; secondly, adopting a waste heat recovery system, using the heat generated by grinding for raw material preheating, reducing boiler energy consumption; thirdly, optimizing the air network design, controlling the air flow speed by adjusting the fan frequency (20-50 Hz), reducing the power consumption of the dust removal system by over 30%.
