High-efficiency cleaning solutions tailored to eliminate heavy impurities in rice, coffee, and milling production lines.
As the cornerstone of global food exports, Thailand's agricultural sector stands at a critical juncture. The modern food safety landscape requires unprecedented purity standards. Export markets, particularly in North America, Europe, and East Asia, mandate strict adherence to Sanitary and Phytosanitary (SPS) measures. For rice mills in Nakhon Sawan, coffee roasters in Chiang Mai, and feed manufacturers in Bangkok, mechanical sorting efficiency directly determines export compliance, profitability, and brand reputation.
Thailand remains one of the world's leading exporters of rice, particularly premium varieties like Hom Mali (Jasmine Rice). However, harvesting methods have shifted rapidly from manual labor to mechanical combine harvesters. While this transition has dramatically accelerated harvest cycles, it has introduced a higher volume of foreign matter—most notably stones, glass shards, metallic contaminants, and soil clods—into the raw harvest supply chain.
Moreover, the Northern region of Thailand has seen a boom in high-value specialty crops, specifically specialty Arabica and Robusta coffee beans. Preserving the integrity of these beans during processing requires specialized density separation that prevents damage to delicate organic structures. Conventional drum cleaning is no longer sufficient; gravity-based fluidization has become an absolute necessity to secure premium margins.
Globally, the grain processing equipment market is shifting toward smart, energy-efficient, and sustainable machinery. The "Waterless Processing Movement" has taken center stage. Wet destoning methods, which require washing grains to separate stones, have been largely phased out due to strict environmental policies prohibiting the discharge of industrial wastewater and the energy-intensive drying phases required afterward.
Modern gravity de-stoners operate under a negative-pressure environment (suction-type), creating a fluidized bed where components of different specific gravities are stratified. This dry separation ensures zero chemical waste, prevents fungal contamination (such as Aflatoxin in humid tropical climates like Thailand), and reduces overall energy footprints by up to 35% compared to traditional blowing-type separators.
Utilizes air suspension and reciprocating vibration to stratify material based on specific gravity differences.
Maintenance-free motor design ensuring uniform deck acceleration and zero mechanical dead zones.
Maintains a clean factory environment by containing micro-dust within closed industrial suction systems.
The tropical climate and humidity of Thailand demand unique structural configurations for industrial equipment. Henan Jiujie Machine Co., Ltd. has developed specialized alloy mesh structures and corrosion-resistant coatings specifically suited for high-humidity coastal and river-basin processing environments. Key local applications include:
A global pioneer in integrated grain processing machinery, engineering design, and industrial manufacturing excellence.
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.
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. Our grain cleaning process is designed to operate without water usage, ensuring no wastewater discharge and supporting environmentally friendly production.
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.
Modern gravity separation relies on a complex balance of fluid dynamics, mechanical oscillation, and multi-deck sieve designs. As a leading manufacturer serving the Southeast Asian market, Henan Jiujie focuses on three key development paths for the next generation of grain de-stoning:
Integrating digital sensors to monitor local atmospheric pressure and humidity variations within the milling hall, adjusting the exhaust fan power dynamically to maintain optimal grain fluidization.
Self-cleaning polyurethane screen balls that continuously clear screen perforations during operation, eliminating the downtime caused by sticky oilseeds or clay dust accumulation.
Specially engineered contact surfaces that comply with the strict sanitary rules of food-grade organic grain processing in Western import markets.
By implementing CNC machinery (such as advanced laser cutters and bending stations), Henan Jiujie ensures the structural stability of the main machine chassis. This minimizes vibrating frequency loss and preserves the uniform separation pattern across the sieve bed, avoiding early mechanical fatigue and maintaining consistent throughput for over 10-15 years of operational life.
Addressing the core technical questions asked by plant managers, design engineers, and procurement directors in Thailand and global regions.
