We report the development of a prototype indirect solar dryer for plaster molds for the ceramic craft industry. The prototype was designedconsidering the reduction of the drying time against the traditional technique, working indoors and using minimal conventionalenergy. The indoor drying chamber has a capacity for 32 plaster molds with a total weight of 425 kg. The drying rate through day andnight, drying efficiency and drying constant were of 0.54 kg-H2O/h, 0.29±0.02% and 0.0094 h-1, respectively. The solar energy suppliedto heat the air of drying was 58% and the remaining 42% was provided by the ambient air. To meet the requirements of the moisturecontent of potters 5.5 days (132 hours) was needed, resulting in a reduction of two-thirds of the traditional drying time of plaster molds(21 days). The continuous rate of drying reveals the solar dryer ability to dry reasonably rapidly under indoor conditions.
