Shijiazhuang Xinlu Technology Co., Ltd. designs Rice Seed Combined Seed Cleaners to address the complex cleaning requirements of rice seeds, which often contain diverse impurities such as dust, chaff, blighted grains, and foreign materials. These systems integrate multiple cleaning technologies into a single streamlined process, ensuring high efficiency without compromising seed integrity.
The cleaning process begins with a de-awning mechanism to remove bristles and coarse impurities. Seeds are then transported via a bucket elevator to a horizontal air-screen system, where aspiration channels with adjustable airflow (8-12 m/s) separate lightweight contaminants like dust and chaff. Cyclone dust collectors settle these impurities for eco-friendly disposal. Subsequent gravity separation removes particles with lower bulk density, including sprouted, insect-damaged, or moldy grains, using vibrating tables with adjustable frequency controls.
The final stage involves multi-layer vibrating screens (typically 3-4 layers) with customizable apertures to eliminate oversized and undersized impurities. Sieves are constructed from durable stainless steel and feature rubber ball cleaning systems to prevent clogging. For rice seeds, perforations range from 1.5mm to 3mm to accommodate varying grain sizes. The machine’s processing capacity ranges from 3 to 50 tons per hour, depending on model configuration and seed condition.
Key technical features include:
Dual-fan gravity separators for uniform air distribution.
Non-destructive bucket elevators to minimize mechanical damage.
Cyclone dust removal systems reducing particulate emissions to <5mg/m³.
Electric control systems with frequency conversion for adjustable vibration amplitude and airflow.
These cleaners are suited for seed processing plants, agricultural cooperatives, and rice milling facilities. By combining pre-cleaning, precision sorting, and dust control, the system ensures seed purity exceeding 98.5% while maintaining germination rates above 95%.
