After months of planting, fertilizing, and tending your corn crop, the final step — shelling — determines how much of your harvest actually makes it to market. Hand-shelling corn is slow, labor-intensive, and leaves kernels damaged or left on the cob. A dedicated corn sheller can process 500–2,000 kg of corn per hour, reducing your post-harvest workload from days to hours.
Whether you're a smallholder growing one acre or a cooperative handling dozens, there's a corn sheller sized for your operation.
All corn shellers operate on the same basic principle:
- Feeding: Whole corn cobs are fed into the machine through a hopper or feed chute.
- Stripping: Inside, a rotating drum or disc with raised ridges or teeth rubs against the corn cobs, stripping kernels from the cob.
- Separation: Kernels fall through a screen or grate, while the stripped cobs are ejected separately through a discharge chute.
- Collection: Shelled kernels are collected in a bag or container below; empty cobs are discharged to the side or behind the machine.
The efficiency of this process depends on the sheller's design, the corn variety, and the moisture content of the harvested cobs.
Compact, lightweight units that clamp to a table or bench. The operator turns a hand crank to drive the shelling mechanism.
