Question

Answer 1

Answer:

solar dryer can most conveniently be classified as direct or indirect.

Direct Solar Dryer – The item to be dried is exposed directly to solar radiation through a transparent material that covers the structure. The heat generated from the solar energy is used to dry the crops or food items and also heats up the surroundings. The main disadvantage of using the direct mode is that the heat that will be absorbed by the item cannot be controlled. Available in many sizes, ranging from kilograms to metric tons, the simplicity of the product and its affordability are its USP.
