Abstract
Postharvest losses (PHLs) of biomaterials, such as vegetables and fruits, significantly
impact food security and economic stability in developing nations. In Tanzania, PHLs
are estimated to range between 30% and 40% for cereal crops and even higher for
perishable crops such as fruits and vegetables. Open-sun drying (OSD) is the most
extensively employed method because of its affordability and simplicity. However,
OSD has several drawbacks, including difficulties in managing drying parameters,
long drying times owing to adverse weather, and product contamination. The solar-
assisted heat pump dryer (SAHPD) is a technology designed as an alternative solution
