Pneumatic Paddy Husker

Pneumatic Paddy Husker

Shijiazhuang Xinlu Technology Co., Ltd. offers the Pneumatic Paddy Husker, a high-efficiency shelling machine that uses precisely controlled airflow and abrasion to remove husks from paddy rice without excessive kernel damage. Its pneumatic design reduces mechanical stress, maintaining high head-rice recovery rates.

Principle of Operation
In the Pneumatic Paddy Husker, raw paddy enters a chamber where a directed air jet lifts and separates the husks from the rice kernels. A series of internal baffles guide the mixture through controlled turbulent zones, facilitating gentle abrasion. The resulting mixture of husks and kernels is then passed through an air-screen separator, where lighter husk material is drawn off, and heavier kernels fall into the clean rice outlet.

Core Features

• Adjustable Airflow System: Variable-frequency fan delivers air volumes from 1 to 6 m³/min, tuned to paddy moisture and variety.

• Abrasion Control Rings: Removable rings with graded surface textures allow operators to balance husk removal efficiency against kernel breakage.

• Air-Screen Integration: On-board aspirator and screens separate air-borne husks from kernels in a single pass.

• Compact Footprint: The vertical design occupies minimal floor space, ideal for space-constrained facilities.

• User-friendly Controls: HMI panel displays inlet air pressure, chamber temperature, and throughput rate.

Benefits to Processors
By relying primarily on airflow rather than mechanical rollers, this husker minimizes kernel breakage—often achieving head-rice yields above 70% compared to 60–65% in conventional roller huskers. The reduced mechanical contact also lowers maintenance on parts such as rollers and bearings.

Installation and Configuration
The Pneumatic Paddy Husker mounts directly onto existing aspiration lines and can be installed on mezzanine platforms for gravity-fed integration. Inlet hoppers and discharge chutes are supplied with adjustable flanges to match customer piping and ducting.

Maintenance and Support
Periodic replacement of abrasion rings, cleaning of air filters, and inspection of internal baffles are the primary upkeep tasks. Shijiazhuang Xinlu Technology Co., Ltd. supplies wear-part kits and offers preventive-maintenance contracts, including remote diagnostics, to optimize machine longevity.
