Which machine is used to detach, separate, and clean corn kernels from cobs?

The machine specifically designed for detaching, separating, and cleaning corn kernels from cobs is the corn sheller. This agricultural device utilizes mechanical means to efficiently remove the kernels from the cob while ensuring that the kernels are intact and minimizing damage during the process.

Corn shellers come in various designs, but they generally feature mechanisms that grip the cob and pull off the kernels by either using sharp edges or rotating motion, allowing for a clean separation. This functionality is crucial in the processing of corn as it prepares the kernels for use in various food products, animal feed, or for further processing.

While the peg-tooth cylinder is a component often found in some harvesting systems and helps in the threshing process, it is not exclusively used for corn. An oscillating screen serves a different purpose in separating materials based on size rather than detaching kernels specifically. A seed cleaner, on the other hand, is primarily designed for cleaning seeds of different types but does not specialize specifically in the shelling of corn. Therefore, the corn sheller is the most appropriate choice for this task.
