Solar dryers are equipment and using solar energy for drying substances, especially food. There are two common types of solar dryers: Direct & indirect. This is a dryer type in which the product to be dried directly absorbs the solar radiation. It is also referred to as a natural convection cabinet dryer, because the solar radiation falls directly on the surface; the product quality is reduced. Heated air from the drying chamber is blown through. A solar dryer's basic function is to heat air with solar energy to a constant temperature, which enables the moisture extraction from crops within a drying chamber. The main objective of flat plate solar air dryer model based on without tray & with tray chamber in Creo parametric software & computational fluid dynamics in Ansys software. Generally, solar air dryer is heat loss is possible, so it’s reduced with help of insulation material (glass wool & polyurethane). To predict the temperature difference in various air flow with insulation material. Furthermore, choose the better insulation material & difference between with & without tray chamber.
