Air Screen Grain Cleaner China Factory

Air Screen Grain Cleaner China Factory

Shijiazhuang Xinlu Technology Co., Ltd. introduces its Air Screen Grain Cleaner designed and manufactured at our China factory to meet the diverse needs of grain processors around the world. This machine integrates screening and aspiration into a single system, allowing processors to remove both coarse debris and fine impurities from various cereal grains, oilseeds, and pulses in one pass.

Process Overview
The raw material is first fed into a vibratory feeder that spreads the grain evenly across multiple screen decks. Each deck is equipped with sieves of progressively finer opening sizes, removing large contaminants such as stones, sticks, and clods. Simultaneously, an adjustable airflow from a centrifugal fan draws out lightweight materials—dust, chaff, and broken hulls—through an aspiration channel. The combination of mechanical screening and pneumatic cleaning ensures that grain enters downstream processes with minimal impurity load.

Key Features

• Multi‑deck Screening: Configurable decks allow for tailored separation according to grain type and impurity profile.

• Adjustable Airflow: Operators can fine‑tune suction intensity to match material bulk density and moisture content.

• Closed‑loop Dust Collection: Integrated ducting and dust collector maintain a cleaner work environment and reduce airborne particulates.

• Heavy‑duty Construction: Fabricated from wear‑resistant steel with food‑grade contact surfaces for longevity and compliance.

• User‑friendly Controls: Centralized panel provides real‑time monitoring of feed rate, fan speed, and screen vibration.

Performance and Benefits
In field trials, the Air Screen Grain Cleaner achieved impurity removal rates exceeding 90% for common contaminants while maintaining throughput capacities up to 30 t/h, depending on grain type. Its compact footprint and modular design allow installation in both new and existing production lines, reducing material handling complexity.

By combining mechanical and pneumatic cleaning steps, processors benefit from a single‑machine solution that addresses a broad spectrum of impurities. The reduced carryover of foreign materials enhances the performance of downstream equipment—such as gravity tables and color sorters—and lowers overall maintenance requirements.

Maintenance and Support
Routine upkeep involves inspecting screen tension, lubricating bearings, and cleaning dust filters. Shijiazhuang Xinlu Technology Co., Ltd. provides detailed maintenance manuals, spare parts packages, and on‑site training to ensure sustained performance. Our China factory adheres to strict quality control processes, so every unit undergoes full factory acceptance testing before shipment.
