High-precision pre-cleaning, grading, and aspiration equipment calibrated for high relative humidity and bulk grain import terminals in Papua New Guinea.
As the economic epicenter and logistics gateway of Papua New Guinea, Port Moresby plays a critical role in national food security. The region relies heavily on ocean-shipped grain imports—primarily high-protein hard wheat from Australia and North America—arriving through Motukea Island Port. Long-distance maritime transit exposes bulk raw grains to ambient humidity, chaff breakdown, foreign particulate contamination, and fine dust accumulation.
For flour millers, commercial bakeries, and feed manufacturers operating across the National Capital District and Gulf Province, deploying industrial-grade wheat cleaning equipment is not merely an operational necessity—it is a vital financial safeguard. Uncleaned grain containing straw, chaff, stones, ergot, or metallic debris drastically reduces roller mill lifespan, degrades flour extraction rates, and increases maintenance downtime.
100% dry air aspiration and density separation eliminates water effluent, fully complying with PNG Conservation and Environment Protection Authority (CEPA) regulations.
Equipped with soft-start heavy-duty motors and variable frequency drives (VFDs) calibrated to handle local 415V/50Hz power fluctuations without thermal trips.
Multi-tier screening sieves remove light impurities, heavy stones, un-threshed heads, and broken kernels in a continuous automated process flow.
Electrostatic powder-coated steel panels and sealed bearing housing designed to resist salt-fog rust in coastal maritime industrial hubs.

Our business covers a wide range of applications, including wheat flour milling plants, feed processing factories, and rice processing plants worldwide.
Our comprehensive product portfolio includes conveying equipment, dry cleaning equipment, precision grading systems, flour milling equipment, and related industrial grain machinery. Over years of intensive R&D, our products have earned widespread acclaim across domestic and overseas agricultural processing markets.
Since our establishment, Henan Jiujie Machine Co., Ltd. has dedicated substantial resources to the research, trial, and optimization of modern grain processing technology. Leveraging deep technical expertise, we deliver fully integrated turn-key engineering solutions across the entire industrial chain—covering raw material intake, portside handling, cleaning, grading, sieving, destoning, grinding, conditioning, and high-speed packaging.
Our complete line of grain processing equipment holds formal ISO9001 Quality Management System Certification and CE Certification. Environmental sustainability is embedded directly into our engineering design: our equipment strictly complies with demanding international environmental standards.
Our dry wheat cleaning process operates entirely without water consumption. This eliminates hazardous industrial wastewater generation, dramatically reduces operating overhead, and ensures seamless compliance with municipal environmental codes in Port Moresby and regional Pacific hubs.
Built for durability and ease of operation, our machinery features low vibration, minimal maintenance requirements, and ultra-quiet motor drives, offering an optimal total cost of ownership (TCO) for local flour milling operators.
Henan Jiujie Machine Co., Ltd. places strong emphasis on continuous manufacturing innovation. Our state-of-the-art facility integrates CNC laser cutters, high-precision machining centers, robotic welding cells, and automated electrostatic spraying lines.
Our engineering workflow achieves optimum purity through physical density separation, screen size classification, and closed-loop pneumatic aspiration without adding excess moisture.
High-speed rotary scalpers strip away oversized foreign matter such as straw, sticks, strings, and large corn cobs before bulk wheat enters main processing silos.
Dual-deck reciprocating sieves sort grains by geometrical size, while upward vertical air channels lift out light dust, husk fragments, and empty glumes.
Fluidized bed gravity tables utilize density differentials to fluidize clean wheat while pushing heavier glass, silica, and mineral stones up the incline for separation.
Rare-earth neodymium magnetic separators trap metallic debris, while mechanical scouring blades polish the wheat kernel to scrape away surface micro-dust and fungal spores.
High-definition CCD sensors detect discolored, ergot-contaminated, or diseased wheat kernels, executing micro-air nozzle rejection at up to 10,000 grains per minute.
Integrated cyclone separators and bag filters trap airborne particulate matter, maintaining factory cleanliness and safeguarding worker respiratory health in tropical climates.
Explore our complete range of seed cleaning, grading, milling, and sorting equipment engineered for multi-grain processing operations.
From portside discharge to high-grade commercial flour milling, Jiujie machinery adapts to distinct processing lines.
High-throughput pre-cleaners installed directly adjacent to bulk vessel unloading cranes at Motukea Island Port, rapidly removing coarse straw and dockside debris before silo elevation.
Multi-pass cleaning sections configured upstream of roller mills in Port Moresby and Lae, ensuring absolute removal of mineral silica and metallic fragments to maintain white flour brilliance.
Versatile screens designed for fast interchangeability, enabling PNG millers to clean wheat, maize, sorghum, and Highland coffee beans on a single modular line.
As a leading international industrial solution provider, Henan Jiujie Machine Co., Ltd. delivers far more than equipment—we provide end-to-end operational security for your processing plant.
By utilizing AutoCAD-based engineering design systems and advanced CNC machining centers, we fabricate custom, high-precision grain cleaning machinery designed for decades of continuous operation. We are committed to providing complete pre-sales consultation, custom layout design, technical support, and responsive regional after-sales service.
Customer satisfaction remains our top priority. We warmly welcome partners, mill owners, and industrial agricultural importers from Port Moresby, Papua New Guinea, and around the globe to connect with us for long-term strategic success.
Henan Jiujie Machine Co., Ltd. continues to drive innovation in automated dry cleaning, smart sensors, and energy recovery.
Real-time vibration sensors detect sieve imbalances and bearing wear before mechanical failure occurs, ensuring zero unscheduled downtime during peak milling cycles.
Automated pressure sensors adjust aspiration fan speed in response to ambient relative humidity changes, reducing power draw by up to 22%.
Integration of UV and InGaAs infrared camera channels allows pinpoint isolation of hidden internal fungal toxins and microscopic grain flaws.
Answers to common engineering, shipping, voltage, and operational queries from Papua New Guinea millers and importers.
Traditional wet cleaning methods (washing machines) introduce excess moisture into grain kernels, which triggers rapid mold growth, mycotoxin development, and rot in hot, humid ambient environments like Port Moresby. Jiujie dry cleaning equipment uses high-velocity closed aspiration and density grading to clean grain thoroughly without water, preserving flour storage stability and eliminating expensive wastewater treatment overhead.
All structural steel components undergo CNC shot blasting followed by multi-coat electrostatic powder painting. Critical internal surfaces and exposed shafts are treated with C4/C5 marine anti-corrosion protective coatings to resist aggressive salt-air exposure at Motukea Island Port and surrounding coastal processing zones.
Yes. We supply heavy-duty industrial electric motors standard rated for 415V, 50Hz, 3-phase power with IP55 protection ratings and Class H insulation. Custom voltage configurations and tropicalized motor windings are integrated to withstand grid voltage fluctuations smoothly.
