AbstractDiscusses the main objective of this research was to perform an experimental investigation into the heat pump drying performance of biomaterials in South African environmental and climatic conditions.Specific objectives to meet the main goal are: to design and construct a heat pump dryer (HPD) according to local conditions; to set up experimental tests and examine the effect of other vital operating conditions such as relative humidity, drying air velocity and ambient temperature; and to analyse the data in terms of the thermal performance of the heat pump and the drying performance of the dryer
