The production of fruits and similar products are important economic factors for the rural population in tropical development and emerging countries. Drying is a well-known and simple possibility for food conservation.

In Burkina Faso, most of the fruit harvesting season is during the rainy season. Therefore, a complete continuous drying process with direct sunlight can’t be assured. Because of this, drying processes often are conducted in gas-fired drying ovens.

The aim of this feasibility study is to develop a fruit dryer on a heat pump basis, which is adapted to local conditions and can be reproduced on the ground, respectively to show its functional demonstration. A first prototype of a low-cost condensation dryer is constructed and tested in Switzerland before it will be employed in Burkina Faso, then is tested and optimized on-site. Partners on-site shall be trained for the reproduction of their own model. A knowledge-transfer regarding applied technology, reproduction, use and service shall occur. An evaluation of energy sources on a renewable basis for electricity for the fruit dryer shall be made. At the same time, an evaluation on organizations and companies for building-up a multiplicative production shall be carried out.
