Beschreibung

Since harvest of mango, litchi and longan is seasonal, drying these fruits is a useful method to ensure their availability throughout the year. Furthermore, drying is a value-adding process because dried fruits fetch higher prices. The objective of subproject E1.2 is to optimize the drying process in terms of dryer capacity, energy consumption and end product quality. Based on modeling and simulation, the drying process in small-scale fruit processing industries of farm cooperatives will be optimized to enhance sustainability of mountainous agriculture.
