Paul Zaake was among the top 25 innovators in the East Africa Postharvest Technology Competition 2017.
Technology : Fruits Village Solar Dryer
The Fruits Village Solar Dryer uses the sun’s energy and wind to dry fruits, preparing them for further processing and packaging. The sliced fruits are spread in an even layer on drying racks inside the solar drier. The air below the semi-transparent collector is heated by the sun and spreads throughout the solar drier. The increased temperature decreases the relative humidity of the air, thereby allowing the air to more efficiently dry the crop. A fan to induce forced convection can be used when required.
Impact : Developed in January 2017, it has been tested for two and a half months. It reduces the time required to dry fruit products from 5 days to 1 day depending on the type of fruit and intensity and duration of solar energy. 5 youths have been employed so far on part-time. 23 fruits farmers have supplied us with fruits while 416 farmers have registered with us to supply us with fruits as soon as we upscale. Local fruits have reached Ugandan supermarkets and are soon headed to Kenya and Germany markets. Over 41 people have visited our site for training on solar drying. We have inspired one farmer in the village to start solar drying and packaging of egg plants.
