Henan Jiujie Machine Co., Ltd. is a highly recognized, professional supplier of complete processing equipment and comprehensive engineering services tailored for the international food production and grain processing industries. Our technical footprints span key agricultural sectors, delivering custom-engineered solutions for wheat flour milling plants, animal feed processing factories, and rice milling complexes globally.

By positioning engineering precision at the heart of our research and development, we have pioneered systems that solve modern crop handling vulnerabilities. Our versatile product portfolio covers essential conveying systems, cleaning and grading machines, high-efficiency flour milling machinery, and computerized grain weighing units. Over decades of consistent technical innovation, our products have gained strong market traction and a highly regarded reputation across domestic markets and international corridors alike.

Complete Processing Line Expertise: We manage everything from raw material intake and bulk grain storage to dry pre-cleaning, grading, conditioning, milling, and precision packaging.

Industrial Processing Chain Integration

Modern crop logistics demand rigorous grain flow tracing and accurate weight calculations. We supply holistic technical planning across the entire bulk material cycle:

  • Intake & Silo Loading: Heavy-duty intake weighing, high-capacity conveying, and initial pre-scalping.
  • Pre-Cleaning & Conditioning: Separation of heavy impurities using destoners and precision double-shaft dampening systems.
  • Milling & Sifting: Accurate flour extraction and multi-stage purification protocols.
  • Final Formulation & Bagging: Semi-automated and fully automated batch packing with weight verification systems.

Global Grain Processing & Weighing Solutions

Addressing macro-industry requirements with customized design, seamless process integration, and real-time operational transparency.

Macro Bulk Logistics

Whether navigating inland transshipment hubs or major maritime grain terminals, high-throughput inline scales are critical. Our solutions prevent processing bottlenecks, ensuring real-time custody transfer data is continuously updated.

Dynamic Process Control

Integrating weighing systems within mills requires deep automation knowledge. Our scales interface directly with central PLC architectures (Siemens, Allen-Bradley) via Profinet/Modbus, helping operators track raw flour extraction rates instantaneously.

Dust Mitigation & Safety

Grain storage environments are highly susceptible to dust explosions. We design our weighing apparatus with ATEX/IECEx certified load cells and dust-tight IP65 terminals, preventing electrical sparks and preserving facility safety.

Production Equipment & Manufacturing Capability

Inside our heavy-industry production facility: combining cutting-edge CAD design, CNC machinery, and advanced surface treatments to deliver durable agricultural equipment.

At Henan Jiujie Machine Co., Ltd., we place strong emphasis on technological innovation and the continuous improvement of our manufacturing capability and product quality. To maintain precision across our product line, we have introduced a series of advanced processing machines, including high-power CNC laser cutting machines, CNC bending machines, and high-precision CNC lathes.

In addition, our workshop is equipped with CNC machining centers, CNC boring machines, surface grinding machines, planers, and other high-precision manufacturing equipment. We have also established an electrostatic spraying production line to enhance the surface quality, corrosion resistance, and durability of our machines. Our processes include steel plate laser cutting, CNC bending, CO₂ arc welding, argon arc welding, robotic welding, and electrostatic surface treatment. These advanced production technologies ensure consistent product quality, structural integrity, and continuous engineering innovation.

Certifications & Quality Standards

CE & ISO9001:2015 Approved Industrial Systems

Our milling equipment and high-precision weighing terminals have obtained ISO9001 quality management system certification and CE certification. The environmental safety and emission profiles of our machinery strictly comply with the requirements of the EU directives.

Importantly, our cleaning processes operate without water usage, ensuring zero wastewater discharge. This waterless engineering methodology supports environmentally friendly production and minimizes operational overhead for mills located in water-scarce regions.

GLOBAL ENGINEERING SERVICES

Customer Service & Project Engineering Lifecycle

As a dedicated industrial solution provider, Henan Jiujie Machine Co., Ltd. delivers complete production setups designed to optimize the grain value chain. By combining AutoCAD-based engineering design with our advanced CNC machining centers, we supply highly precise, long-lasting machinery at competitive prices.

We offer comprehensive support through pre-sales consultations, technical planning, custom equipment customization, and after-sales service. Customer satisfaction is our central priority, and we welcome long-term partnerships with grain millers and industrial contractors worldwide.

Local Support, Compliance & Operational Integration

Adapting heavy grain processing machinery to meet local safety regulations, plant footprints, and challenging environments.

North American & EU Standards

We adapt our electrical assemblies to conform to local codes. This includes using UL-listed control panels for the United States and Canada, and guaranteeing full ATEX Directive 2014/34/EU compliance for dust-heavy zones in European milling plants.

Sanitary Design & Materials

All product-contact surfaces in our scales and sifting units are manufactured using food-grade SUS304 or SUS316L stainless steel. This prevents corrosion and crop contamination, meeting strict FDA and EHEDG guidelines.

Flexible Installation footprint

Our engineering teams use 3D modeling to integrate new weighing scales, pneumatic vacuum conveyors, and double-shaft dampeners into existing mills. This minimizes installation time and avoids costly structural modifications.

Industrial Technology Roadmap

Leading the next generation of smart milling, cloud data integration, and high-performance grain processing.

Continuous Engineering & Innovation Milestones

Stage 1: IoT Smart Terminals

Integrating IoT-enabled transmitters within our gravimetric scales. This allows operators to monitor batch metrics and run-rates remotely using web-based interfaces.

Stage 2: Self-Optimizing Dampeners

Developing dynamic feedback loops connecting dampeners with inline moisture sensors. This automatically adjusts dampening levels based on real-time wheat density.

Stage 3: Zero-Emission Processing

Optimizing dry destoning and gravity separation machinery to reduce air emission profiles and save power during continuous operations.

Frequently Asked Questions & Technical Reference

Common questions regarding grain weighing systems, milling plant layout design, and operational specifications.

Q1: What weighing accuracy can I expect from Henan Jiujie's grain weighing systems?
Our high-precision weighing systems use temperature-compensated load cells combined with advanced digital filtering algorithms. Under normal flow rates, our systems maintain a static weighing accuracy of ±0.2%, ensuring precise inventory control and accurate flour extraction calculations.
Q2: How do you handle dust safety and mitigate explosion hazards in dry milling plants?
Dust safety is a key priority. Our electrical enclosures are rated IP65/IP66, and we offer optional ATEX-certified load cells and intrinsically safe barrier isolators for plants operating in hazardous dust environments (Zone 20/21/22). Additionally, our conveying and cleaning systems feature dust extraction hoods to capture airborne particles at the source.
Q3: Can your machinery be integrated into existing third-party PLC control networks?
Yes, our electrical control systems support standard communication protocols, including Profinet, Profibus DP, Modbus TCP/IP, and EtherNet/IP. This allows our scales, dampeners, and feeders to communicate directly with your existing SCADA or PLC network.
Q4: What is the benefit of your waterless grain cleaning process?
Traditional wet cleaning systems consume large amounts of fresh water and generate wastewater that requires treatment. Our dry cleaning process uses gravity separation, destoners, and vibrating screens to remove impurities without water. This reduces environmental impact and lowers utility costs.
