Discover our high-precision machinery designed for maximum extraction rates, strict sanitation, and heavy-duty industrial flour production operations.
Henan Jiujie Machine Co., Ltd. is an acclaimed, professional supplier of integrated turnkey equipment and engineering solutions tailored for the global food production and grain processing industries. Our business and technical capabilities span a wide range of agricultural and industrial applications, including high-capacity wheat flour milling plants, customized animal feed processing factories, and state-of-the-art rice processing installations.
Our expansive product portfolio incorporates advanced grain conveying systems, high-efficiency seed and grain cleaning machinery, precision flour milling roll equipment, and diverse sorting and grading systems. Over the decades, our technologies have achieved deep market penetration, earning robust recognition and praise from customers in both domestic industrial centers and demanding international export markets.
From initial design concepts using advanced computer-aided software to the final assembly of massive mill structures, Jiujie covers the entire workflow:
Our footprint in engineering precision, global compliance, and industrial capacity.
Analyzing mechanical stresses, metallurgical demands, and commercial trends shaping the modern milling landscape.
Modern roller mills operate under immense physical and thermal stress. High-grade double-pour centrifugal casting ensures that our rolls carry a highly compressed outer chilled layer (hardness of 68-78 Shore C) for maximum wear resistance, while maintaining a ductile core to absorb sudden mechanical shocks from foreign material in the grain stream.
Flour extraction efficiency depends heavily on the geometry of the roll fluting (corrugation). The number of flutes per inch, the helix angle, and the arrangement (Sharp-to-Sharp, Sharp-to-Dull, Dull-to-Dull) are strategically engineered to optimize bran shearing and endosperm release, yielding premium baking flours with minimal ash content.
Rising energy costs have forced global mill operators to seek premium-engineered mechanical components. Roller mill units that minimize friction, maximize throughput per kilowatt-hour, and operate without water-intensive grain conditioning cycles represent the vanguard of sustainable, modern food processing operations.
Henan, China stands as a global powerhouse in the manufacture of heavy machinery and grain processing plants. At Henan Jiujie Machine Co., Ltd., we combine this geographic and supply chain advantage with heavy investment in cutting-edge robotics and computer numerical control (CNC) systems. This synergy allows us to produce components that rival Western European alternatives in mechanical longevity while maintaining highly competitive global capital expenditure (CAPEX).
Our raw material procurement network ensures top-tier steel and alloy elements are sourced under strict quality assurance frameworks. With vertically integrated production—from casting and welding to CNC milling and electrostatic painting—we maintain absolute control over tolerances, delivering rollers that operate with micron-level gap accuracy.
| Mechanical Specification | Henan Jiujie Industry Standard | Typical Competitive Tier |
|---|---|---|
| Roll Hardness Depth | 15mm - 20mm Chilled Layer | 8mm - 12mm Standard Layer |
| Dynamic Balance Tolerance | G2.5 (High Precision) | G6.3 (Standard Precision) |
| Gap Adjustment Precision | 0.01 mm increments | 0.05 mm increments |
| Surface Treatment | Electrostatic Multi-layer Spraying | Basic Industrial Prime & Paint |
| Certification Profile | ISO9001, CE, EU Safety Compliant | Local Regional Certifications Only |
For modern B2B food safety audits, reliability and compliance are non-negotiable. Henan Jiujie Machine Co., Ltd. builds equipment in strict compliance with the ISO9001 quality management system. Our flour milling equipment has obtained both the ISO9001 and CE certifications, allowing hassle-free installation and validation in European Union member states and other strictly regulated jurisdictions.
Our environmental protection standards comply fully with relevant EU requirements. A prime example is our waterless grain cleaning process: by utilizing high-efficiency mechanical air separators, destoners, and dry scourers, we eliminate the need for heavy water usage. This avoids the generation of municipal wastewater and cuts down on utility bills while preserving the grain’s organic integrity.
Our facility features modern machine tools that ensure our engineering designs are translated into durable, high-performance milling equipment.
We operate high-precision CNC laser cutting machines, CNC bending machines, CNC lathes, and heavy machining centers. These tools process metal plate thicknesses with sub-millimeter accuracy, ensuring perfect fits for structural frames, feed gates, and bearing housings.
Our workshop features CNC boring machines, surface grinding units, and planetary planers. These tools are critical for achieving the precise flatness and concentricity required for high-speed roller rotation without vibration.
By employing robotic CO₂ arc welding, argon arc welding, and automated electrostatic spraying lines, we construct rust-resistant housings that withstand the humid, dusty interior environments of busy commercial flour mills.
From regional wheat types to coarse grain sorting, discover how our equipment adapts to local raw grain characteristics.
Hard wheats require high shear and robust breaking forces to separate the stubborn endosperm from the bran. In contrast, soft wheat milling relies on gentle compression to avoid starch damage. Jiujie’s customizable fluting configurations adapt precisely to local grain profiles in Europe, Central Asia, and North America.
Maize milling requires a distinct method due to its tough outer husk and oil-rich germ. Our rollers are calibrated for high-efficiency cracking and de-germing, allowing processors in East Africa and South America to obtain pure, low-fat maize meal and grits for local consumption and industrial starch production.
The rise of gluten-free and alternative flours (such as sorghum, millet, rye, chickpeas, and beans) calls for specialized roller surfaces. Jiujie engineers custom corrugations that prevent the clogging associated with oily or high-fiber alternative grains.
At Henan Jiujie Machine Co., Ltd., we deliver more than individual machines. We provide complete, integrated production solutions that enhance your facility's output and return on investment.
By utilizing AutoCAD-based engineering design systems and advanced machining centers, we supply high-precision, durable milling lines at highly competitive price points. We support our customers through every step of their project lifecycle:
