| Solar fruit drying is a technology that is successfully applied on both domestic and commercial scale among smallholder farmers in Uganda. However, existing solar drying technologies are marred with multiple deficiencies such as inefficient conversion of trapped solar radiation to meet required enthalpy, low throughput, long drying times, and inherent difficulty to achieve acceptable hygiene among others. This review examines existing solar drying technologies in Uganda, highlighting design constraints and plausible solutions for supporting the growing fruit drying industry. The common types of solar driers in Uganda are the static-bed box type solar dryer model, the PPI tunnel solar dryer model, the NRI Kawanda cabinet solar dryer, the hybrid tunnel solar... |
