Legume Gravity Separator Supplier

Legume Gravity Separator

Shijiazhuang Xinlu Technology Co., Ltd. is proud to introduce its Legume Gravity Separator, a precision separation solution designed specifically for beans, peas, lentils, and other legume crops. By leveraging controlled airflow and deck vibration, this machine distinguishes particles based on minute density differences, ensuring that only the highest-quality legumes proceed to packaging or further processing.

Working Principle
The Legume Gravity Separator operates on the density stratification principle. Material is evenly distributed across a gently oscillating deck while an adjustable air stream flows upward through the seed bed. Denser, healthy legumes sink into the deck grooves and advance toward the clean-product outlet, while lighter impurities—such as broken seed coats, immature grains, and small dust particles—rise and are carried away by the airflow. Precise control over the deck slope, stroke, and air volume allows operators to adapt separation settings to different legume sizes and densities.

Key Features

• Customizable Deck Geometry: Interchangeable deck mats with various groove depths accommodate a range of legume types, from large kidney beans to small chickpeas.

• Variable Airflow Control: A frequency-controlled fan modulates air velocity between 0.5 and 3 m³/min, matching the bulk density and moisture content of the legume feed.

• Adjustable Vibration Mechanism: Stroke amplitude (2–6 mm) and frequency (400–600 vpm) can be fine-tuned to optimize stratification without causing seed damage.

• Modular Construction: Easily accessible panels and quick-release clamps simplify maintenance and deck replacement, minimizing downtime.

• User-Friendly Interface: A central control panel displays real-time separation metrics—such as deck load and airflow rate—and stores up to ten preset recipes for rapid changeovers.

Operational Benefits
In practical use, the Legume Gravity Separator delivers consistent purity levels, reducing broken seed carries and improving downstream processing yields. Commercial growers and packers have reported up to a 20% decrease in rejects and waste when integrating this separator into their cleaning lines. The machine’s ability to handle variable feed qualities makes it particularly valuable during harvest peaks when field moisture and impurity content can fluctuate significantly.

Maintenance and Support
Routine maintenance tasks include cleaning air filters, inspecting deck mats for wear, and lubricating the oscillation bearings. Shijiazhuang Xinlu Technology Co., Ltd. provides comprehensive maintenance manuals, spare-parts kits, and on-site training to ensure long-term reliability. Our engineering team can also assist with initial setup and performance tuning to match specific legume varieties and regional seed standards.
