CEO Ismael Mayanja came up with a simple, inexpensive device to process hand-harvested corn in Africa and efficiently remove waste chaff.  Their flagship product (SUNSULA) efficiently cleans maize in seconds and produces quality grain for safe and longer storage, easy processing into other foods, and healthy consumption.  The conventional method is to winnow the grain by hand, which leaves a lot of chaff in the product and lowers its value.  You can watch an animation of the product in action here.
