China Rice Seed Processing Line Factory

China Rice Seed Processing Line

Shijiazhuang Xinlu Technology Co., Ltd. offers the China Rice Seed Processing Line, a standalone system engineered for the delicate nature of rice seeds, from paddy to polished seed. With capacities from 4 t/h to 18 t/h, this line ensures efficient impurity removal and size grading without compromising seed viability.

Sequence of Operations

1. Paddy Pre‑Cleaner

• Dual‑deck screens remove straw, stones, and large foreign matter.

• Aspirator extracts fine dust and loose hull fragments.

2. Magnetic Separation

• High-intensity drum captures metallic particles.

3. Pre‑Dehusker (Optional Module)

• Gentle abrasion removes hulls for processes requiring brown rice seed.

4. Precision Sieving

• Multi‑deck fine screens (0.5–2 mm apertures) grade seeds by length and width.

5. Gravity Separator

• High‑accuracy deck stratifies seeds, removing immature or broken kernels.

6. Final Aspiration

• Low‑pressure air flow lifts away remaining husk fragments and dust before buffering.

Core Components

• Vibrating Feeders & Screens: Customizable amplitudes to accommodate moisture variations.

• Aspirator Blowers: Variable-speed fans with stage‑wise filter cleaning mechanisms.

• Sieving Units: Stainless‑steel circular screens driven by balanced eccentric shafts.

• Gravity Table: 1.8 m² deck, stroke adjustable from 2–5 mm, angle from 0–7°.

• Control Cabinet: PLC with recipe management for different rice varieties, including indica and japonica.

Use Cases and Benefits

• Seed Certification: Meets standards for purity and germination uniformity in certified seed programs.

• Commercial Seed Producers: Delivers uniform seed lots ready for coating or direct sale.

• Research Facilities: Flexible recipe storage aids rapid testing of new rice cultivars.

Customization Options

• Integrated Dehullers: Option to add paddy dehusking ahead of sieving for brown‑rice seed.

• Moisture Control: Inline grain conditioners to adjust moisture to target levels.

• Dust Management: Closed‑loop aspiration with cyclonic separators for environmental compliance.
