Wheat Seed Air Screen Cleaner

Wheat Seed Air Screen Cleaner

The Wheat Seed Air Screen Cleaner from Shijiazhuang Xinlu Technology Co., Ltd. is a dedicated standalone machine engineered to handle the specific challenges of wheat seed preparation. Its combination of screening and aspiration ensures that both large debris and fine particulates are efficiently removed, preserving seed integrity and improving downstream performance.

Working Principle
Wheat seed is fed into a vibratory inlet that gently spreads kernels across a two‑deck screening assembly. The upper deck, equipped with coarse screens, traps straw, stems, and oversized impurities, while the lower deck uses finer perforations to separate smaller debris. A calibrated upward airflow, generated by an aspirator fan positioned beneath the decks, lifts dust, chaff, and light de‑hulling fragments into a dust collection system. Cleaned seed exits through a bottom discharge.

Key Components

• Dual‑Deck Screens: Coarse (2–4 mm) and fine (0.8–2 mm) panels for staged impurity removal.

• Aspirator Fan: Delivers 1–3 m³/min airflow; speed is adjustable to match wheat moisture content.

• Vibration Drive: Counterbalanced motor offering stroke amplitudes of 3–6 mm at 400–600 vpm.

• Dust Collector: Cyclonic separator with slide‑out bin for captured fines.

• Operator Panel: Controls vibration on/off and aspirator speed; optional digital readout for airflow.

Applications and Benefits

• Seed Conditioning: Prepares wheat for gravity separation, color sorting, or seed coating by removing abrasive debris.

• Yield Protection: Reduces kernel breakage with low‑impact handling and precise airflow control.

• Throughput: Processes up to 20 t/h under typical conditions, depending on impurity load.

• Ease of Use: Rapid setup and minimal adjustment points reduce operator workload.

Maintenance and Customization
Routine servicing includes screen cleaning, filter replacement, and lubrication of bearings. Optional features include PLC integration for recipe storage, automated screen sweeping, and expanded dust‑collection capacity for high‑dust environments.
