Abstract :

The sun is the source of all energy. The heat energy obtained from the sun is known as solar energy. It finds various applications. Applications of solar energy are commercially available and are used by millions of people in various parts of the world. One of the promising areas of the application of solar energy is solar air heater. Solar air heaters are used for drying and space heating. The use of drying has been demonstrated as an application of air heaters. Villagers are mainly involved in agriculture and drying is one of the important processes in it. There are many problems in direct drying. Solar air heater is one of the best methods of drying products in a hygienic manner. We have planned to design and construct a solar air heater with evacuated tubes, which increases the efficiency of the air heaters to a greater extent. Air is passed through the evacuated tubes and gets heated by the collector unit and circulated through the crop in the drying unit. Many agriculture products such as coffee, pepper, cereals, cardamom, potato slices and pappads were dried with it and its efficiencies were calculated
