    Question

    In the context of renewable energy applications in

    agriculture, solar dryers are often preferred for drying horticultural produce. What is the principal advantage of using an indirect type solar dryer over a direct type, especially for light-sensitive agricultural products?
    A It dries produce faster due to direct solar radiation. Correct Answer Incorrect Answer
    B It allows for natural ventilation without any heat loss. Correct Answer Incorrect Answer
    C It prevents photodegradation by shielding the product from direct sunlight. Correct Answer Incorrect Answer
    D It uses electricity to supplement solar heat, increasing energy efficiency. Correct Answer Incorrect Answer
    E It uses water as a medium to transfer solar heat to the product. Correct Answer Incorrect Answer

    Solution

    Indirect type solar dryers use a separate solar collector to heat air, which is then passed over the product in a drying chamber. This setup protects the product from direct sunlight, preventing photodegradation and preserving quality in light-sensitive products like herbs, flowers, and some fruits.
