Abstract :

The objective of this paper is to design, develop and evaluate performance of an Indirect-Type Passive pop can solar dryer in a passive mode using thermal energy storage and without thermal energy storage for the drying of product. Drying is one of the oldest methods using solar energy where the product such as vegetables, fruits, fish, and meat to be dried exposed directly to the sun. This method has many disadvantages such as spoilt products due to rain, wind, dust, insect infestation, animal attack and fungi. Foods should be dried rapidly, but the speed of drying will cause the outside becomes hard before the moisture inside has a chance to evaporate and it will affect the quality of dried product due to over drying. Food products, especially fruits and vegetables require hot air in the temperature range of 45–75 °C for safe drying.. This design was employed and has compared with the performance testing through parameters such as temperature, moisture content. It was shown that the use of pop can solar dryer reduced the drying time significantly and essentially provides better product quality compared with conventional drying method. The effect of temperature to moisture contents against time and rate of drying are studied in this research.
