Abstract

Solar drying is an important technique for preserving food and agricultural products. This is a form of energy that has developed, as it is sustainable and low cost, however its intermittent nature is a limiting factor. Thus, the objective was to evaluate a solar dryer with integrated to a paraffin-based thermal energy storage system, as a phase change material (PCM), in the Brazilian cerrado region. Two dryers were built: one with PCM (Dryer 1) and the other without (Dryer 2). To carry out the experiment, the banana apple was dried in three experiments, corresponding to the days of exposure of the equipment to the sun. The dryers were evaluated for thermal efficiency and mass efficiency. The highest temperature measured was 71.7 °C for Dryers 1 to Experiments 1 and 2. The highest thermal yield observed was for dryer 2, with 45.82%. Dryer 1 showed higher mass efficiencies in the three drying days. Both dryers are suitable to produce dried bananas.
