Critical Review On Different Technologies Of Solar Dryers

The storage of agricultural products has long been a problem in developing countries. Because most countries' populations are growing at a quicker rate, food shortages are a possibility in such countries. Many ways of food preservation are utilized to prevent this problem, with solar drying being one of the most prominent. Because solar energy is inexpensive and readily available, it is advantageous to dry agricultural goods in the most efficient manner possible. Direct sunlight exposure to dry things has a negative impact on product quality. It is planned to review a solar dryer technology to achieve higher drying rates in different climates. The primary goal of this study is to review all active and passive solar dryer technologies. Finally, it is concluded that, the food dried in a solar dryer was higher than food dried in direct sunshine. Furthermore, the forced convection solar dryer dried faster than the natural convection solar dryer.
