Henan Qiyi Machinery (QIE) specializes in the research, development, and manufacture of high-quality continuous annular extractors, designed specifically for large-scale oil and fat processing plants. These extractors are suitable for efficient vegetable oil extraction from a variety of oilseed crops, including soybeans, rapeseed, and peanuts. Crafted from high-strength, corrosion-resistant materials, these extractors support 24/7 continuous, stable operation, achieving the dual advantages of high recovery rates and low energy consumption. Certified to ISO 9001 for quality management and ISO 14001 for environmental management, they meet international export standards and are a trusted choice for customers worldwide. Equipped with automated control systems and intelligent monitoring capabilities, these extractors are easy to operate and maintain, significantly improving production efficiency and profitability. A one-year warranty and professional technical support guarantee long-term, stable returns for our customers.
1. Continuous operation mode offers high production capacity and low energy consumption, making it suitable for large-scale industrial production. 2. Fully automatic control and real-time data monitoring ensure stable and reliable operation. 3. Corrosion-resistant structural design adapts to various oil processing conditions. 4. High oil recovery rate improves raw material utilization. 5. Export-grade quality certification meets international market access requirements.
It is suitable for large-scale vegetable oil production enterprises, grain and oil processing groups, agricultural cooperatives and overseas oil processing projects, and is especially suitable for procurement and use by customers in emerging markets such as the Middle East, Southeast Asia and South America.
The material first enters the storage bin at the top of the extractor and, propelled by a scraper chain, slowly moves toward the spray leaching section (straight section), where it is sprayed with solvent multiple times. The material then passes through the curved section and enters the lower layer for further leaching. Finally, it is rinsed with fresh solvent. The wet meal continues in the draining section, where it naturally desolventizes before being discharged through the bottom outlet.
The core advantage of the annular extractor is that the material can be completely turned over when passing through the curved section, effectively improving the uniformity of extraction. At the same time, the shallow material layer (generally 700-900mm) is conducive to solvent penetration and mixed oil diffusion, shortening the extraction time, reducing the solubility of wet meal, and keeping the residual oil content stable below 1%.
The power system utilizes a cycloid reducer, hardened gear reducer, and chain drive structure to drive the drive shaft, driving the heavy-duty conveyor chain and chain frame in a closed-loop operation. Select models feature a tensioning device above the drive shaft to ensure smooth and reliable chain operation, enhancing overall machine stability and service life.
