The Corn Sheller is a low-cost device for removing corn kernels from the cob that makes it possible to shell maize (corn) several times faster than manual shelling. Maize shellers can be made in many ways using a variety of materials. These instructions show how to make a maize sheller out of a single piece of sheet metal which is formed and then joined together using a simple jig, though corn shellers can also be made from many other materials.
Developed by: Marco Villagarcia, an engineer from Cusco, Peru, based on an injection molded plastic corn sheller from Malawi, documented by the D-lab. Copyright © Massachusetts Institute of Technology.
D-Lab is a program at MIT that fosters the development of appropriate technologies and sustainable solutions within the framework of international development. Included in their outreach programs are several class offerings at MIT, NGO partnerships, and information related to appropriate technology and sustainable development.
Some DIY technologies require specialized materials or special training. If your organization is interested in this technology, you are what we call a ‘technology seeker’, and funding for materials or training for this DIY technology may be available through Kopernik.
Technology seekers interested in becoming part of Kopernik can do so by filling out the registration and proposal form downloadable here. Once the registration form is submitted, Kopernik will review the application and conduct due diligence to determine whether the organization meets the requirements of Kopernik.
