Solar drying is a method of removing moisture from food or other materials using sunlight. This process involves placing items, such as fruits or vegetables, in a sunny location where the heat and light from the sun help evaporate the moisture. It is an energy-efficient and cost-effective way to preserve food, extending its shelf life without the need for electricity. The technique is simple and can be done using various setups, such as solar dryers or open-air drying racks. Solar drying is commonly used in agriculture and food preservation, making it a popular choice in many regions around the world.
