Shijiazhuang Xinlu Technology Co., Ltd. announces its Paddy Gravity Separator, designed to improve milling efficiency and rice quality by removing light impurities and immature paddy before hulling. By applying gravity separation technology, this machine helps mills reduce breakage rates and optimize milling yields.
Operating Principle
Raw paddy is fed onto an oscillating deck where it is stratified by density. Mature, heavy paddy moves toward the cleaner discharge, while lighter material—such as unfilled grains, chaff, and dust—is carried by an upward airflow into the reject channel. Adjustable deck slope and stroke amplitude allow customization for different rice varieties and moisture contents.
Key Features
High-Capacity Decks: Wide deck surfaces accommodate up to 20 t/h, depending on paddy condition.
Airflow Calibration: Variable-frequency drives control fan speed for precise separation under varying ambient conditions.
Robust Construction: Reinforced steel frame and wear-resistant decks stand up to abrasive paddy husks.
Feed Gate Adjustment: Stepped gates ensure even material distribution across the deck width.
Dust Control System: Enclosed airflow paths minimize dust emission and support cleaner working environments.
Applications and Benefits
Rice mills incorporating the Paddy Gravity Separator experience reduced head rice loss—often 5–7% lower—by ensuring only fully mature paddy enters the huller. The removal of inert material also reduces wear on hulling components and lowers energy consumption during milling. For seed-production operations, this separator enhances germination uniformity by eliminating shriveled or unfilled kernels.
Maintenance and Support
Regular checks of deck mats, fan bearings, and vibration mechanisms are recommended during scheduled downtime. Shijiazhuang Xinlu Technology Co., Ltd. offers turnkey installation, operator training, and preventative-maintenance packages, ensuring the separator remains a reliable component of any milling line.
