The machine used for removing seeds from maize cobs is called a sheller. A sheller is a device that is specifically designed to remove the kernels or seeds from the cob of maize. The machine works by mechanically separating the kernels from the cob using a rotating cylinder or a set of rollers with ridges or teeth that grip and remove the seeds as they pass through. Once the kernels are separated, they can be used for a variety of purposes, such as for human or animal consumption, or for further processing into products like cornmeal or corn syrup.
