Explore our top-tier industrial machinery engineered to optimize material sorting, purification, and pneumatic delivery across grain processing plants.
Bridging the gap between raw grain handling and food manufacturing through cutting-edge technology and high-precision milling plants.
Henan Jiujie Machine Co., Ltd. is a professional supplier of complete equipment and engineering services for the food production and grain processing industries. Our business covers a wide range of applications, including wheat flour milling plants, feed processing factories, and rice processing plants. Our product portfolio includes conveying equipment, cleaning equipment, flour milling equipment, and other related machinery. Over the years, our products have been widely recognized by customers both in domestic and international markets.
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.
We leverage AutoCAD-based engineering design systems and CNC-driven machining centers to transform initial specifications into high-performance machinery. In the globalized food economy, grain mill operators require modularity, precise particle sizing, and mechanical reliability. Henan Jiujie delivers these standards, helping processing facilities secure optimal yields and reduce downstream grain waste.
Understanding the economic and technical demands of the global durum wheat processing industry.
Semolina, obtained by grinding the endosperm of durum wheat (Triticum durum), is the foundation of pasta, couscous, and specialty flatbreads worldwide. Industrial mills must achieve maximum semolina yields while minimizing bran contamination. Modern food plants demand grinding equipment capable of high-throughput sizing while preserving gluten starch properties.
Unlike standard wheat flour milling, semolina grinding targets large, granular particles with minimal starch damage. This requires precise compression ratios, dedicated roll corrugations, and advanced air-purifier separations. Process control systems enable operators to fine-tune particle distributions to meet global food standards.
Modern milling machinery must comply with CE safety and hygiene parameters. From ATEX-compliant explosion proofing in dusty environments to food-contact-approved mechanical surfaces, Henan Jiujie integrates safety regulations directly into every machine's structural architecture.
Achieving maximum extraction rate and high-purity end products through structured mechanics.
Grain storage silos feed durum wheat into high-stroke de-stoners and cleaners. Gravity destoning systems separate impurities (stones, glass, heavy dirt) based on specific gravity differentials without using water, ensuring dry, wastewater-free preprocessing.
Integrated pneumatic vacuum conveyors and high-sealing side inlet rotary valves transfer grain safely without manual handling. The closed-loop pneumatic flow limits dust dispersion, ensuring clean factory floors and reduced combustion risks.
Our mills utilize specific roll corrugations and fine speed adjustments to peel the bran jacket without pulverizing it. The mix is sent to semolina purifiers, which use air currents and vibrating sieves to separate pure endosperm from clinging bran.
Milled semolina is processed through high-efficiency sifting machines to isolate target fractions. The final product is moved to automated VFFS flour packaging systems or bagging lines for sealed preservation, preventing moisture damage and shelf degradation.
Adapting to diverse climates, grain varieties, and regional manufacturing requirements.
Arid Conditions & Water Preservation: The MENA region is one of the largest consumers of semolina for couscous and traditional flatbreads. Our waterless dry cleaning technology eliminates the need for grain washing, saving water resources and preventing wastewater discharge in arid environments.
Regulatory Compliance & Cleanroom Processing: Modern pasta facilities in Europe and North America operate under strict environmental and noise control regulations. Henan Jiujie machines carry CE certifications, low noise outputs, and ATEX dust protection levels to fit seamlessly into modern industrial complexes.
Modular & Scalable Grain Lines: For agricultural operators in Latin America and Sub-Saharan Africa, capital investment security is paramount. Our compact, portable sifting systems and modular grinding machines allow mills to scale up their production capacities incrementally with low operational overheads.
