Engineered for maximum extraction rate, high grain purity, and low operational cost
The global grain milling industry is undergoing a structural paradigm shift. Rapid urbanization, population growth in developing regions, and rising standards for food hygiene and shelf life have transformed grain processing from traditional mechanical grinding into a highly optimized, automated biochemical extraction process. Modern flour milling is no longer just about reducing particle size; it is about maximizing starch damage optimization, maintaining high gluten integrity, controlling ash content fractions, and ensuring minimal energy consumption per ton of throughput.
In regions such as Sub-Saharan Africa, Latin America, and Central Asia, the transition from basic milling to commercial-scale automated production lines is driven by the demand for high-quality staples like wheat flour, maize grits, and semolina. For grain processors, selecting the right manufacturing partner is a critical capital decision. Industrial milling machines must maintain steady mechanical output under variable local power conditions, adapt to different grain moisture profiles, and operate with low maintenance cycles. Henan Jiujie Machine Co., Ltd. serves this exact commercial landscape, engineering durable, high-yield milling technologies designed to optimize return on investment (ROI) for global agricultural enterprises.

Since its establishment, Henan Jiujie Machine Co., Ltd. has been dedicated to the research and development of grain processing technology and machinery. With extensive industry experience, we are able to provide integrated solutions across the entire grain and food processing industrial chain. Our solutions cover multiple stages, including raw material collection, storage, cleaning, grading, sieving, grinding, mixing, shaping, production, and packaging. This allows our clients to scale their production and meet international quality benchmarks reliably.
Adaptability across regions with distinct dietary profiles and industrial environments
Grain processing demands vary significantly by region. A machine configuration that is optimal for soft wheat processing in the Middle East might not be suitable for processing hard vitreous maize in Sub-Saharan Africa. Henan Jiujie customizes its flour milling plants to align with regional grain types, dietary standards, and local physical infrastructures.
In African countries, maize meal, semolina, and local maize grits form the core diet. Machinery must handle tough grain types, perform efficient degermination to remove oil-rich germ, and produce white corn flour with low fat content to maximize shelf-life under high ambient temperatures. Our 30tpd to 300tpd maize milling plants feature multi-pass peeling and precise degermination machinery to optimize yield and consistency.
The MENA region requires fine flour for traditional flatbreads and high-extraction semolina for couscous production. Our roller mills feature dynamic hydraulic roll adjustments and cooling air circulation. This layout controls roller surface temperature, preventing starch damage and ensuring optimal dough elasticity for local baking processes.
In these markets, raw grains often arrive with higher percentages of impurities, dust, and dynamic moisture variances. Our high-efficiency dry pre-cleaning systems separate heavy stones, light chaff, and metallic debris without water. This design ensures clean raw materials enter the rollers, protecting downstream machinery from early wear.
Precision industrial production and heavy equipment engineering
Henan Jiujie Machine Co., Ltd. places strong emphasis on technological innovation and continuous improvement of manufacturing capability and product quality. We have introduced a series of advanced processing equipment, including CNC laser cutting machines, CNC bending machines, and CNC lathes. This high degree of precision ensures that our machinery components meet tight dimensional tolerances, resulting in lower friction, minimal vibration, and extended service life.
In addition, we are 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 further enhance product surface quality and durability. The integration of these production methods allows us to control the manufacturing process from raw steel plates to the final assembled mill.
Our manufacturing 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 and continuous innovation. By utilizing robot-assisted welding, we achieve uniform structural weld strength, which is critical for equipment that operates under heavy dynamic loads.
Compliance with international regulatory standards and water-free cleaning technologies
Our flour milling equipment has obtained the ISO9001 quality management system certification and CE certification. The environmental protection standards of our equipment comply with relevant EU requirements. Quality control is maintained throughout every step of production. Raw materials undergo ultrasonic testing, and assembled roller mills complete 24-hour dynamic rotation balancing tests to verify alignment before shipping.
A key technical feature of our processing line is our dry cleaning technology. Traditionally, wheat cleaning required wet scouring, which generated high volumes of contaminated wastewater. Our grain cleaning process is designed to operate without water usage, ensuring no wastewater discharge and supporting environmentally friendly production. Using pneumatic separations, high-impact scoured dry de-stoners, and multi-stage dust aspiration, we achieve high grain purity without the environmental footprint of wet systems. This reduces water costs and minimizes moisture management issues in hot or humid climates.
Our products are characterized not only by stable performance but also by easy installation, convenient maintenance, and low operating costs. With advanced technology, reliable quality, and modern design, our equipment has earned high appreciation from clients worldwide. By optimizing spare parts interchangeability, we help processing plants lower their inventory costs and simplify maintenance procedures.
Pioneering smart milling, IoT monitoring, and energy conservation
The flour milling industry is transitioning toward digital operation. Henan Jiujie is updating its machinery portfolio to align with these trends, focusing on three core areas:
Our next-generation industrial roller mills feature integrated vibration, temperature, and wear sensors. These sensors connect directly to central SCADA systems, allowing operators to monitor roller bearing performance in real time. This approach identifies maintenance needs early, helping plants prevent unplanned downtime.
Dynamic grain moisture changes can affect milling extraction rates. Our upcoming automated dampening systems measure wheat moisture inline before milling. The system automatically adjusts water flow, maintaining uniform moisture levels across production runs to optimize extraction and flour quality.
Pneumatic conveying of milled products accounts for a large portion of a mill's energy consumption. We are redesigning our vacuum and positive-pressure pneumatic lines to reduce turbulence and pressure losses. Combined with IE4/IE5 motors, this update reduces power usage per ton by up to 12%.
