Maize Seed Air Screen Cleaner

Maize Seed Air Screen Cleaner

Shijiazhuang Xinlu Technology Co., Ltd. offers the Maize Seed Air Screen Cleaner as a standalone solution for pre‑processing maize seed. Combining mechanical sieving and air aspiration, this unit efficiently removes oversized debris, lightweight impurities, and fine dust to prepare seed for further grading or treatment.

Working Principle
Maize seed enters the inlet hopper and is conveyed onto a robust vibratory screen deck. The deck’s perforations retain larger foreign bodies—broken cobs, stones, and stalk bits—while an aspirator mounted beneath the deck draws air upward. Dust, chaff, and small husk fragments are lifted and separated through a duct into a cyclone. Clean seed particles, free of both coarse and fine impurities, exit the deck to subsequent handling.

Key Components

• Heavy‑Duty Screen Deck: Available in multiple mesh sizes (3–6 mm) to suit different maize kernels.

• Adjustable Aspirator: Fan capacity from 0.5 to 3 m³/min, controlled via a simple speed dial or VFD.

• Vibration Drive: Counterbalanced motor delivering adjustable amplitude (3–7 mm) and frequency (400–600 vpm).

• Dust Collection Module: Removable cyclone or bag‑filter canister for captured fines.

• Control Interface: Onboard panel for vibration on/off and airflow adjustment.

Use Cases and Benefits

• Seed Preparation: Ensures that downstream grading machines and seed treaters are protected from grit and dust.

• Improved Seed Uniformity: Removes lightweight impurities that could skew seed density sorting.

• Operational Flexibility: Capable of 15–25 t/h throughput, depending on kernel moisture and impurity load.

• Ease of Installation: Standalone design fits into both new and existing seed lines without major modifications.

Maintenance and Customization
Screen blocks slide out for cleaning or replacement; the aspirator filter can be accessed via hinged panels. Optional upgrades include larger‑capacity fans, secondary dedusting modules, and customized hopper capacities. Shijiazhuang Xinlu Technology Co., Ltd. provides tailored spares kits and on‑site training to support continuous operation.
