How to Use Industrial Corn Duhusk Machine
What Is a Large Agricultural Corn Husking Machine?
A large agricultural corn husking machine is a heavy‑duty mechanical device designed to automatically remove husks and silk from corn ears at high throughput. It is widely used in dry field corn harvesting, fresh sweet corn processing, seed corn production, and corn storage centers.
Compared with small or manual huskers, large‑scale models feature:
● High working efficiency: typically 2–6 tons per hour, or 8,000–15,000 ears per hour
● Stable husking rate: usually above 96–99%
● Low grain damage rate: less than 0.5–1%
● Continuous, automatic operation: feeding, husking, husk discharge, and clean corn output
● Strong durability: thick steel frame, wear‑resistant rubber rollers, cast‑iron components
● Adaptability: works for fresh corn, mature field corn, seed corn, and various ear sizes

Modern large corn husking machines often integrate mechanical roller husking, air‑jet cleaning, and silk removal to deliver very clean finished corn ears.
Core Structure and Working Principle
Understanding the structure helps you operate and adjust the machine more accurately.
Ⅰ. Main Components
1. Feeding Hopper & Conveyor: Uniformly feeds corn ears into the husking chamber to prevent clogging.
2. Husking Roller Group: The core part. Most machines use paired rollers: one cast‑iron ribbed roller, one high‑friction rubber roller. They rotate inward to grip and pull husks downward.
3. Pressure Regulating System: Controls pressure between rollers to avoid breaking corn while ensuring complete husk removal.
4. Air‑Blowing System (on advanced models): Blows away loose husks and corn silk for cleaner output.
5. Husk Discharge Outlet: Separately collects husks for recycling or disposal.
6. Clean Corn Outlet: Outputs fully husked corn ears.
7. Power & Transmission System: Electric motor or diesel engine for stable power.
8. Frame & Safety Guards: Ensures stability and operator safety.
Ⅱ. Working Principle
● The entire process is continuous, automatic, and adjustable.
The equipment is controlled by a three-proof electric control box with panel-mounted buttons. The operation steps are as follows:
3. Twist out the emergency stop switch on the control box panel. At this time, the red power indicator light on the control box will stay on.
4. A professional electrician shall check the rotation direction of each power component one by one. If any rotation is reversed, stop the machine and cut off the power immediately to adjust the phase, ensuring all rotations are correct.
5. Equipment startup: After the power is on, turn on the spray water. Start the machine in the following sequence:
Husk Discharge ON → Husk Lifting ON → Receiving ON → Return ON → Peeling Swing ON → Vibration ON → Feeding Speed ON → Lifting ON.
6. Feeding speed regulation procedure:
Press the “Feeding Speed ON” button on the panel, then press the green “RUN” button on the inverter in the upper right corner.
After the inverter value stabilizes, turn the “- / +” knob clockwise to adjust the feeding speed as needed. The normal value is around 30.
7. The feeding machine is equipped with a simple steam wilting device. Operation procedure:
First, press the green “Lifting ON” button, fill the feeding hopper to more than 2/3 full, then turn on the steam for about 2 minutes.
Then start the equipment in the order described in item (5).
The feeding hopper must maintain more than 1/2 of the raw materials during steam wilting. Steam volume and time can be adjusted according to actual conditions.
Benefits of Using a Large Corn Husking Machine
For modern large‑scale agriculture, the corn husking machine is no longer optional equipment—it is a core productivity tool that determines harvest speed and product quality.
