Explore our premium component line-up, engineered to seamlessly integrate into custom configurations and scale operations globally.
Delivering high-reliability, customized OEM and ODM grain milling systems designed to optimize extraction rates, preserve product quality, and secure continuous plant uptime.
In the highly competitive global food processing market, the choice of a grain milling plant machinery supplier represents a critical investment decision. Henan Jiujie Machine Co., Ltd. serves as a reliable engineering partner, providing customized, complete engineering solutions for the grain and food processing industries. Our technical capacity covers a broad spectrum of requirements, ranging from small-scale grain processing operations to large-scale wheat flour milling plants, feed processing facilities, and integrated rice mills.
Rather than simply supplying generic equipment, we deliver custom-designed systems optimized to align with regional grain properties and specific output targets. From raw material storage, pneumatic conveying, and intensive cleaning, to precise moisture conditioning, roller milling, plansifter grading, and modern packaging, we support the entire value chain. This ensures a consistent, high-yield final product that meets strict international safety and quality standards.
The global flour milling industry is undergoing a transition driven by rising operational costs, stricter food safety regulations, and a growing focus on sustainability. As a leading exporter, Henan Jiujie Machine Co., Ltd. continuously updates its manufacturing processes to align with these key industry trends:
Modern milling plants increasingly rely on real-time feedback loops. By integrating PLC-controlled automated systems and sensor networks, plants can dynamic-adjust roll gaps, monitor bearing temperatures, and regulate pneumatic conveying velocity, minimizing downtime and optimizing energy consumption.
Stricter environmental regulations make traditional, water-intensive grain washing processes less viable due to wastewater disposal costs. Our advanced dry-cleaning grain systems utilize high-efficiency vibratory separators and air-recycling aspirators to remove impurities without consuming water, minimizing environmental impact.
Preventing cross-contamination and dust accumulation is critical for regulatory compliance and safety. Using high-grade stainless steel contacts, self-cleaning rotary valves, and closed-loop pneumatic conveying systems reduces dust leakage, limiting explosion hazards and ensuring sanitary operations.
Industrial grain processing equipment is rarely a one-size-fits-all product. Different geographic regions present distinct grain characteristics (such as hard wheat, soft wheat, corn, or cassava) and varying local grid standards, emission codes, and building dimensions. We support global operators through comprehensive OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) integration:
A reliable flour production line requires balanced capacity matching across all process stages to prevent bottlenecks and ensure consistent throughput.
Our complete processing solutions are engineered to ensure smooth material flow, consistent moisture conditioning, and precise grinding action across every stage of production:
Raw grains are unloaded into reception hoppers and moved to silos via bucket elevators or pneumatic conveyors. For large-scale plants, our PLC-controlled screw or hydraulic jacking systems facilitate safe, efficient silo construction and raw material storage management.
Magnetic separators, vibratory screeners, and destoners remove metal fragments, stones, and organic chaff. Next, the wheat enters our intensive dampening machine, where automatic moisture controllers precisely regulate water addition to temper the bran, facilitating clean separation during milling.
Tempered grain is fed into roller mills. The bran, middlings, and semolina are systematically separated through break and reduction rolls. We utilize high-precision CNC-ground rollers to maintain accurate roll gaps, ensuring consistent particle size distribution.
Milled stock is transferred to high-capacity plansifters or vibratory flour sifters. Using multi-layered, food-grade screen meshes, the stream is graded by size, returning coarse particles to the reduction rolls and directing fine flour toward packaging.
To prevent material degradation and maintain sanitary standards, we utilize closed-loop, positive or negative pressure pneumatic conveying systems. These lines rely on our VCF Series Rotary Airlock Valves to maintain constant pressure differentials and prevent dust leakage.
The finished flour is transferred to bagging bins and packed using high-speed packaging machines. From 1kg consumer bags to 50kg bulk woven sacks, our automated filling systems use load-cell technology to ensure precise weight control.
Quality equipment starts with robust manufacturing. We invest in CNC machinery and modern fabrication processes to ensure long-term durability and performance.
At Henan Jiujie Machine Co., Ltd., we prioritize technological innovation and continuous improvement in our manufacturing capabilities. Our facility features advanced processing machinery, including CNC laser cutting systems, CNC bending machines, and high-precision CNC lathes. These systems allow us to work with close tolerances, ensuring perfect component alignment and minimizing vibration during operation.
Our manufacturing processes include laser cutting, CNC bending, CO₂ arc welding, argon arc welding, robotic welding, and electrostatic surface treatment. Combining automatic robotic welding with manual finishing helps prevent fatigue cracking in high-stress areas, such as plansifter frames and rotary valve housings. Finally, our electrostatic spraying production line applies a durable coating that resists abrasion, moisture, and corrosion.
Ensuring compliance with global quality and environmental standards for food processing equipment.
Building high-performance food processing equipment requires strict adherence to quality and safety standards. Our manufacturing plant operates under the ISO9001:2015 Quality Management System, verifying that every stage—from material sourcing to component assembly—follows documented quality procedures. Additionally, our key machinery series carry the CE Certification, confirming compliance with European safety, health, and environmental standards.
Environmental responsibility is integrated into our equipment designs. For example, our water-free cleaning systems help eliminate wastewater discharge, supporting eco-friendly production goals. Furthermore, we design dust control systems that meet modern emissions regulations, maintaining low airborne particulate levels to support a clean, safe working environment.
Standardized assembly procedures, material traceability, and thorough testing protocols ensure that each component conforms to specified design tolerances before shipment.
Equipment designs incorporate safety shielding, emergency stop systems, electrical isolation, and explosion-venting provisions on pneumatic conveying components.
By eliminating water-intensive washing steps and utilizing dry-cleaning aspiration methods, we help operations lower water consumption and avoid wastewater treatment requirements.
From pre-sales planning to commissioning and lifecycle support, we provide comprehensive technical services.
We work closely with clients throughout the project lifecycle to ensure equipment matches operational requirements:
