Iketsetse Single Stroke Maize Sheller
Terry Ellard and Elliot Litsebe Tsiame
The Iketsetse single stroke maize sheller is a device used for fast separation of the kernels from the cob in maize.
The Iketsetse single stroke maize sheller is a device used to separate the kernels from the cob faster than traditional methods and other crank type shellers. It consists of a leveraged plunger that pushes the ear of maize through a ring of spring teeth arranged so as to remove all the kernels from the cob with one motion.
In shops in Lesotho the production cost of the Iketsetse Single Stroke Maize Sheller includes:
Costs of Materials: 19 USD, Labor costs: 12 USD, Consumables estimated: 4 USD, Overhead estimated: 6 USD. Therefore making total cost of unit production approximately 41 USD.
Adding a cost of sales of 15% and profit of 10 USD results in a sell price of 65 USD
Individually manufactured by skilled local metalworkers and adapted for production with available materials. Iketsetse Micro Enterprise Development Company has a workshop with the jigs and fixtures necessary to manufacture the shellers and conducts training.
Iketsetse Micro Enterprise Development Company sells shellers directly to end users.

Iketsetse Micro Enterprise Development Company provides training on local manufacturing of farm tools to ensure that users are able to maintain equipment independently.
The sheller is manufactured with locally available materials and repairs are possible via trained staff.
- Shells corn cobs at least 16 times faster than than traditional manual methods and 6 times faster than crank type shellers.
- The machine can yield 20 liters of shelled kernels in 18-20 minutes.
