Seed cleaning is the foundation of high-quality crop production. A seed cleaner (or seed cleaning machine) is designed to remove impurities such as dust, husks, broken seeds, and foreign particles from harvested seeds. The result is pure, uniform, and high-germination planting material.
Modern seed cleaning machines have evolved from simple air-sieve designs to fully automated systems integrating air suction, vibration, gravity separation, and electronic sorting. In China, several leading manufacturers have become known globally for producing durable, efficient, and cost-effective equipment.
At the forefront of this industry is Shijiazhuang Xinlu Technology Co., Ltd., a professional supplier offering complete seed cleaning lines and turnkey plant solutions for a wide range of crops.

A seed cleaner operates on the principle of separation by size, weight, and aerodynamic properties. The process typically includes several stages:
Feeding: Seeds enter the machine through a controlled feeding hopper.
Air Suction: Light impurities such as dust and husks are removed by airflow.
Screening: Multi-layer vibrating screens separate seeds by size.
Gravity Separation: Heavy and healthy seeds are separated from lightweight or damaged ones.
Final Output: Cleaned seeds are collected or sent to coating and packaging sections.
Modern seed cleaners often feature digital control systems, adjustable fans, and interchangeable sieves for flexible operation across multiple seed types.
Xinlu provides complete seed cleaning lines, including layout design, installation, commissioning, and operator training. Clients receive an optimized, ready-to-use system.
The company continuously improves airflow balance, vibration control, and screen efficiency to achieve maximum seed purity.
