Artisanal solar dryer adapted to the climate of the highlands of Madagascar

Abstract

Madagascar has vast cultivable land and great seasonal variation in agricultural production. At market levels, it encounters a period of overproduction which leads to a large drop in product prices. Thanks to the climatic conditions of this large island which has the advantage of sunshine throughout the year, we have studied and created in this article an Artisanal solar dryer adapted to the climate of the highlands of Madagascar. We are interested in studying a solar ginger dryer because this spice takes on important roles in terms of nutrients. Our dryer is made from locally available materials. According to our studies followed by experiments, we have observed the effectiveness of our homemade solar dryer. The maximum internal temperature of our dryer reaches a value of 50°C after 50 minutes of operation. The nutritional values of dried ginger are preserved, which proves the effectiveness of our dryer.
