The paper focuses on the experimental study and implementation of the forced convection indirect solar dryer based on the phase-change material (PCM). The dryer consists of an air solar collector combined with a PCM cavity and a drying chamber. The paper investigates thermal processes in the solar dryer affecting agricultural product drying. It is shown that the air solar collector integrated with paraffin wax, is a thermal energy storage, which provides the automatic control for temperature and humidity. Experiments with sliced bananas include the hot air supply provided by the thermal energy storage with or without the solar radiation. It is found that at least 7 hours after sundown, the dry air temperature is 2 to 7.5°C higher than the ambient air.
