info@mission-mac.com
The 5XCM Series De-Awning Machine is a specialized pre-cleaning solution for rice and wheat facilities, removing awns from rice ears and husks from wheat kernels to prevent screen clogging and enhance downstream efficiency. It uses low-speed spiral beaters with stationary drum beaters to create friction, stripping awns while preserving grain integrity. Achieves ≥98% awn removal and ≤0.01% breakage.
Available in three models with capacities from 5 to 15 t/h, the 5XCM series scales from small mills to large industrial plants. Positioned upstream of precision cleaning and milling, this machine ensures high efficiency and low grain damage, making it ideal for rice and wheat processors seeking reliable pre-cleaning.
Key Features
High-Efficiency De-Awning With Ultra-Low Breakage
This De-Awning Machine achieves ≥98% awn removal and ≤0.01% breakage through gentle low-speed spiral beaters. High removal prevents screen clogging in downstream equipment; minimal breakage preserves whole grain yield for premium markets. Proven performance supports quality assurance and maximizes profitability for rice and wheat processors.
Dual Beater System With Adjustable Spiral Beater Angle
Rotating spiral beaters work with stationary drum beaters to create persistent friction. Beater angle adjusts 0°–30° externally to match crop maturity and variety—aggressive for tight awns, gentle for easy release. This awn remover optimizes results without tools, reducing downtime during changeovers between different grains.
External Adjustability for Drum Friction and Fill Level
Drum friction and fill level controls are adjustable from outside the housing, allowing real-time optimization without stopping production. Lower friction for delicate varieties, higher for tough crops; fill level regulates throughput. This pre-cleaning machine provides fine-tuning capability across diverse conditions, maximizing efficiency and grain integrity.
Wear-Resistant Manganese Steel for 10+ Year Service Life
All high-contact components (spiral beaters, drum walls) use manganese steel, offering exceptional hardness under abrasion. Guaranteed service life ≥10 years under normal operation, reducing replacement costs and downtime. Modular design allows easy replacement of individual parts. The De-Awning Machine delivers low total cost of ownership.
Integrated Dust Control With Quick-Connect Extraction Ports
Inlet and outlet ports feature quick-connect dust extraction interfaces for easy attachment to facility aspiration systems. Captures awn fragments, dust, and chaff, preventing emissions to the work area. Improves operator safety, simplifies regulatory compliance, and keeps downstream equipment cleaner—ideal for facilities with strict environmental standards.
Low-Speed Drive, Versatile Crop Handling, and Durable Build
Low-speed drive system (≤0.01% breakage) handles rice, wheat, barley, oats, sorghum, and millet. Three models offer 5–15 t/h capacities. Carbon steel with anti-corrosion coating; stainless steel optional. This de-awning equipment scales from small mills to large industrial plants, providing gentle, reliable pre-cleaning for multiple grain types.
Technical Specifications
Model | Overall Size | Awn removal rate | Crushing rate | Capacity | Power |
| 5XCM-5.0 | 1200*800*1250 | ≥98 | ≤0.01 | 5 | 5.5 |
| 5XCM-10.0 | 1550*1000*1570 | ≥98 | ≤0.01 | 10 | 11 |
| 5XCM-15.0 | 1750*1500*1800 | ≥98 | ≤0.01 | 15 | 15 |
Note: Capacities vary based on crop type, moisture content, and awn characteristics. Adjustable parameters enable optimization for specific processing requirements.
FAQ
What is a de-awning machine used for?
A de-awning machine removes awns (bristles) from rice and wheat grains before precision cleaning and milling. This prevents screen clogging, improves cleaning efficiency, and protects downstream equipment from contamination.
How does the 5XCM de-awning machine work?
It uses rotating low-speed spiral beaters on the main shaft and stationary beaters on the drum wall to create persistent friction. This action separates awns from rice ears and husks from wheat kernels without damaging the grain.
What de-awning efficiency can I expect?
The 5XCM series achieves ≥98% awn removal rate with ≤0.01% breakage—industry-leading performance that ensures high-quality pre-cleaning results.
How can I adjust the machine for different crops?
Adjust the beater angle (0-30° range), drum friction, and fill level to match crop characteristics and maturity. All adjustments can be made externally without interrupting production.
What is the expected lifespan of wear components?
Spiral beaters and drum walls are constructed from wear-resistant manganese steel with a guaranteed service life of ≥10 years under normal operating conditions.
Can this machine handle both rice and wheat?
Yes. The adjustable parameters allow the same machine to be configured for rice awn removal, wheat threshing, and processing of barley, oats, and sorghum.
How does the dust control system work?
Quick-connect dust extraction ports at inlet and outlet allow connection to facility dust collection systems, creating negative pressure that prevents particulate emissions.
