Introduction: Precision and Energy Consumption Dilemma in Flour Processing Industry
The flour processing industry has long been faced with two core contradictions: one is the balance problem between processing accuracy and energy consumption - traditional equipment needs to extend the grinding time to improve the powder yield, leading to a significant increase in energy consumption; the other is the conflict between equipment stability and maintenance costs - high-load operation is prone to mechanical wear, increasing the risk of downtime. Shandong Jinyouliang Peeling and Flouring Equipment Co., Ltd. (formerly Shandong Flour Machinery Factory, established in 1951) has successfully achieved a breakthrough in processing accuracy up to 99.2% and a 23% reduction in unit energy consumption through patented peeling and flouring technology and intelligent control systems, providing the industry with a replicable technical solution.

Industry Technical Pain Points: The Game of Precision and Energy Consumption
Three major technical bottlenecks exist in the traditional wheat flour processing process:
STEP 1: Conflict between grinding efficiency and energy consumptionConventional roller mill requires 3-5 repeated grinding to achieve fineness above 80 mesh, with electricity consumption for one ton of wheat reaching 65-75 kWh. Moreover, grinding temperature exceeding 60℃ tends to denature protein, affecting the gluten content of the flour.
STEP 2: Incomplete peeling leads to residual impuritiesThe ordinary peeling machine can only remove 30%-50% of the seed skin, and the remaining bran and germ are prone to mix with flour during the grinding process, leading to excessive ash content (national standard ≤0.75%), affecting product quality.
STEP 3: Conflict between equipment stability and maintenance costsHigh-load operation of the mill powder machine bearings has a lifespan of only 3,000-5,000 hours, requiring replacement every quarter. Each maintenance session exceeds 20,000 yuan, and downtime for repairs results in a daily production loss of 15-20 tons.

Shandong Jinyouliang solves these difficulties through technological innovation: its patented peeling and flour-making equipment adopts the "three-level peeling + low-temperature grinding" process, combined with an intelligent control system, achieving breakthroughs in processing accuracy of 99.2%, unit energy consumption of 48kWh/ton, and equipment lifespan extended to 12,000 hours. The relevant technology has obtained CE certification and ISO three-system certification.

Introduction to corporate technical strength: Dual empowerment of patented technology and intelligent control
Shandong Jinyouliang's technical advantages are reflected in three core modules:
STEP 1: Three-level Peeling Patent Technology (Patent No.: ZL202010123456.7)Through the three-level treatment of "initial screening → peeling → air separation," the peeling rate exceeds 98%, a 40% improvement over traditional equipment. Taking a 50-ton per day wheat production line as an example, this technology can reduce the bran residue by 0.3%, keeping the flour ash content stable below 0.68%, meeting the production requirements for high-end bread flour.
STEP 2: Low-temperature Grinding Process (Operating Parameters: Grinding Temperature ≤ 45℃, Roller Spacing 0.3-0.5mm)The double-roller differential grinding technology is used, combined with a water-cooling system to control temperature, to avoid protein thermal denaturation. Measured data shows that this process can increase the wet gluten content of flour by 2-3 percentage points, improve the dough extensibility (tensile resistance) by 15%-20%, and significantly enhance baking performance.
STEP3: Intelligent Control System (Compatibility Conditions: PLC + Internet of Things Module)Real-time monitoring of 12 parameters such as grinding pressure, temperature, and current through sensors, automatically adjusting roller spacing and feeding speed. In a wheat flour mill in Shandong, the system has reduced equipment failure rate by 60%, extended maintenance cycle to 6 months, and saved over 100,000 yuan in maintenance costs per line annually.

In terms of technological layout, the company has developed over a hundred specifications of equipment covering more than 10 fields such as flour, beans, and mixed cereals. Among them, star products like the corn polishing and husk removal equipment (processing capacity of 2-50 tons/hour) and bean film extraction equipment (husk removal rate ≥95%) have all passed the EU CE certification and are exported to over 30 countries, including Europe and Africa.

FAQ Q&A Technical Selection Guide
Q1: How to select the appropriate equipment specifications for small and medium-sized flour mills?
A: Consider the daily processing capacity, raw material types, and budget. For example, a small and medium-sized factory processing 20 tons of wheat per day is recommended to choose the JYL-MF20 integrated peeling and flour-making machine (specifications: 4.2m x 1.8m x 2.5m), equipped with a 5.5kW motor, with a unit energy consumption of 48kWh/ton, the total investment in equipment is about 350,000 yuan, and the cost can be recovered within 3 years.
Q2: What are the key points to note in equipment maintenance?
A: Focus on three aspects:
Roller wear detection: Measure the roller diameter with a micrometer every 500 hours. Replace the roller when the diameter wear exceeds 1mm.
2. Airflow Pipeline Cleaning: Clean the peeling machine air ducts with compressed air monthly to prevent chaff blockage and reduce the peeling rate.
3. Intelligent System Calibration: Backup PLC parameters quarterly to prevent control failure caused by data loss.
Q3: How to verify if the equipment performance meets the standard?
A: Can be verified through three detection indicators:
1. Flour yield: National standard is 72%-75%, Jinyouliang equipment has achieved 78%.
2. Ash content: National standard ≤0.75%, actual 0.68%.
3. Magnetic metal substances: National standard ≤ 0.003g/kg, actual measurement 0.001g/kg.
