Experimental Investigation of Solar Dryer using Phase Change Material

The sun is the most important source of heat and light in the universe and also one of the major renewable sources. In many countries, they are utilizing solar energy in the agricultural area to preserve vegetables, fruits, other crops, and meat. Utilizing solar energy into useful work is our main project. Solar dryers are the devices that use solar energy to dry substances, especially food products. A similar investigation of a portion of the accessible solar dryers demonstrate that the solar dryer moderately decreases the drying time of item through the reasonable utilization of warmth stockpiling materials like rock bed, pebbles, sand, clay and so on. A phase change material (PCM) is a substance with a high heat of fusion which, is melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. The fundamental goal of the present exploratory examination is to build up a solar dryer as a method for nourishment drying, helped by the PCM, and to research the impact of PCM on warmth accessibility, heat use and drying energy of sustenance. Hence the experimental procedure was done to access the comparative study of natural convection solar dryer and the natural convection solar dryer using PCM, which is used to increase the drying rate of the product.
