Product Details

The 5XCM Series De-Awning Machine is a specialized pre-cleaning solution designed for rice and wheat processing facilities. Positioned upstream of precision cleaning and milling equipment, this machine removes awns (bristles) from rice ears and separates husks from wheat kernels, preventing screen clogging and significantly enhancing the efficiency of downstream cleaning operations. The 5XCM series operates on a proven friction-based de-awning principle: continuously rotating low-speed spiral beaters on the main shaft work in conjunction with stationary beaters mounted on the drum wall to create persistent agitation and friction.

This mechanical action effectively strips awns from rice grains and threshes wheat kernels from their ears while maintaining exceptional grain integrity. The machine delivers industry-leading performance metrics: ≥98% awn removal rate and ≤0.01% breakage rate, ensuring that valuable grain is preserved while contaminants are eliminated. Available in three models with capacities ranging from 5 to 15 tons per hour, the 5XCM series offers scalable solutions for operations from small-scale mills to large industrial processing facilities.

Key Features

Proven High-Efficiency De-Awning with Ultra-Low Breakage

The 5XCM de-awning machine delivers exceptional performance metrics validated through extensive field operation. The machine achieves ≥98% awn removal rate, effectively eliminating the bristles that cause screen blinding and reduce cleaning efficiency in downstream equipment. Equally important, the breakage rate is maintained at ≤0.01%—an industry-leading figure that ensures virtually no grain loss during the de-awning process. This combination of high removal efficiency and minimal grain damage is achieved through careful control of the friction mechanism: the low-speed spiral beaters create gentle but persistent agitation that separates awns without crushing or cracking kernels.

For rice processors, this means higher yields of whole grain for premium markets; for wheat millers, it means cleaner product entering the tempering and milling stages. The proven performance metrics provide measurable confidence in the de-awning process and support quality assurance documentation requirements.

Dual Beater System with Adjustable Spiral Beater Angle

At the heart of the 5XCM series is a dual beater system that combines rotating spiral beaters with stationary beaters mounted on the drum wall. The spiral beaters on the main shaft rotate continuously at low speed, while the stationary beaters provide fixed resistance, creating the friction necessary for awn removal. The beater angle is adjustable within 0° to 30°, allowing operators to fine-tune the aggressiveness of the de-awning action based on crop characteristics. For early-harvest rice with tightly attached awns, a more aggressive angle may be selected; for fully mature grain where awns release more easily, a gentler angle reduces unnecessary friction.

This adjustability ensures optimal results across different varieties, maturity levels, and growing conditions. The adjustment mechanism is designed for operator convenience, allowing changes to be made without specialized tools and minimal downtime during changeovers between crops.

External Adjustability for Drum Friction and Fill Level

In addition to beater angle adjustment, the 5XCM series offers externally adjustable drum friction and fill level controls that enable operators to optimize performance without interrupting production. The drum friction setting determines the intensity of contact between grain and working surfaces; lower friction is appropriate for delicate varieties or when minimizing breakage is paramount, while higher friction increases throughput for tough-to-thresh crops. The fill level control regulates the volume of grain present in the working zone at any given time, affecting both throughput and de-awning efficiency.

By adjusting these parameters in combination with beater angle, operators can fine-tune the machine to achieve superior de-awning performance across a wide range of crops and conditions. All adjustments can be made from outside the machine housing, reducing safety risks associated with internal access and minimizing downtime for changeovers.

Wear-Resistant Manganese Steel Construction for 10+ Year Service Life

De-awning is inherently abrasive, with awns and grain surfaces creating wear on machine components over time. The 5XCM series addresses this challenge through the use of high-quality wear-resistant manganese steel for all high-contact components, including spiral beaters and drum walls. Manganese steel exhibits exceptional hardness under impact and abrasion—properties that extend component life far beyond that of standard carbon steel. The result is a guaranteed service life of ≥10 years under normal operating conditions, significantly reducing replacement part costs and maintenance downtime over the equipment's lifespan.

When wear eventually occurs, the modular design allows for straightforward replacement of individual beaters or drum sections rather than complete component replacement. For facilities processing abrasive grains or operating multiple shifts, this durability translates directly to lower total cost of ownership and predictable maintenance scheduling.

Integrated Dust Control with Quick-Connect Extraction Ports

De-awning operations generate significant dust and fine particulate matter that can impact operator health, facility cleanliness, and downstream equipment performance. The 5XCM series addresses this with integrated dust extraction interfaces at both the inlet and outlet ports. These quick-connect ports allow for rapid attachment to facility dust collection systems using industry-standard connections, creating negative pressure within the machine that prevents particulate emissions to the surrounding environment.

The dust control system captures the fine material released during the de-awning process—including awn fragments, dust, and light chaff—before it can escape into the work area or accumulate on downstream equipment. For facilities operating under strict environmental regulations or those seeking to improve workplace conditions, this feature simplifies compliance and creates a cleaner, safer operating environment.

Versatile Crop Processing Capabilities Across Grains and Cereals

While optimized for rice and wheat processing, the 5XCM de-awning machine is engineered to handle a range of crops requiring awn removal or threshing. Primary applications include: rice processing for removing awns from paddy before husking; wheat processing for separating kernels from wheat ears prior to cleaning; barley processing for removing awns before malting or milling; oat processing for dehulling applications; and sorghum and millet processing where awn removal improves cleaning efficiency.

The adjustable parameters—beater angle, drum friction, and fill level—allow the same machine to be reconfigured for different crops as seasonal processing demands shift. This versatility makes the 5XCM series a valuable asset for facilities that process multiple grain types or that serve diverse markets with varying product specifications.

Low-Speed Drive System for Gentle Grain Handling

The 5XCM series is powered by a low-speed drive system specifically selected to balance effective de-awning with gentle grain handling. The main shaft rotates at a carefully calibrated speed that provides sufficient friction to remove awns without subjecting grain kernels to the high-impact forces associated with faster equipment. This low-speed operation delivers two key benefits: minimized grain breakage (≤0.01%) and reduced wear on components, extending service life.

The drive system is engineered for reliability, with sealed bearings that resist dust ingress and motors selected for continuous-duty operation in demanding grain processing environments. For facilities concerned about product quality and yield, the low-speed design provides confidence that grain entering downstream processes is intact and free from the micro-cracking that can affect milling performance.

Durable Construction with Optional Stainless Steel

The 5XCM series is built to withstand the demands of continuous grain processing. Standard construction features carbon steel components with a durable anti-corrosion coating, providing excellent resistance to rust and abrasion in typical indoor applications. The high-wear zones—including beaters and drum walls—utilize the premium manganese steel described above. For facilities with specific requirements, we offer stainless steel construction options for the main housing, providing enhanced corrosion resistance for operations processing acidic grains, those requiring frequent wash-down cleaning, or facilities operating in high-humidity environments.

All fasteners and access points are designed for easy service access, with inspection doors positioned to facilitate routine checks of beater condition and wear levels. This emphasis on durable, maintainable construction ensures that the 5XCM series delivers reliable performance year after year.
