Manual hand operated corn sheller

Types of manual hand operated corn shellers

Corn is a staple food in many parts of the world. Before it can be used, it has to be removed from the cob. This is where a corn sheller comes in. The machine is designed to remove the kernels from the cob, making it easier to cook and eat. Although the device is now often operated manually, there are still many different types of shellers used today.

• Hand crank corn sheller: This sheller is usually mounted on a wooden box or a metal container. The cobs are fed into the machine, and the handle is turned manually. As the handle is turned, the metal wheel pulls the corn through the machine. The kernels are separated from the cob and collected in the container. This type of corn sheller is quite efficient and can shell many cobs in a short time.

• Pedal-powered corn sheller: This machine is almost the same as the hand crank sheller. The only difference is that it is powered by pedaling, which makes it more efficient than the hand crank model. With the pedal-powered sheller, the operator can use their body weight to power the machine while their hands are free to feed the cobs into the sheller.

• Drum corn sheller: This model of corn sheller has a small drum that is turned by a hand crank. The cobs are fed into the machine, and the rotating drum rubs the kernels off the cob. The drum can be made from different materials, but cast iron is the most common. This machine is quite easy to operate and can be used to shell small to medium batches of corn.

• Pull-type corn sheller: This is a portable corn thresher that is usually pulled by a tractor. It is suitable for large-scale corn farming and commercial use. The machine has a large metal cylinder with spikes that rotate. The cobs are fed into the machine, and the rotating cylinder pulls the kernels off the cob. This type of corn sheller is very efficient and can process large amounts of corn in a short time.

• Box hand corn sheller: This is a hand operated maize sheller that is mounted on a wooden box. The sheller has a hand crank that is turned manually. The cobs are fed into the machine, and the kernels are separated and fall into the box. The wooden box collects the kernels and also serves as a base to stabilize the sheller during operation.
