Analysis of Direct, Indirect and Hybrid Solar Dryer

The purpose of the paper is to gain knowledge and compare the various kinds of Solar Crop Dryer (SCD) used to dry agricultural crops. There are many types of SCD and conventional methods that are being researched. Analyzing and comparing various kinds of SCD shows that sun utilization is a promising technology. The availability of space in urban areas, irregular sunshine, high initial cost and facilities problem are the major obstacles to their acceptance by Indian farmer. Research and development should overcome all of these limitations. In order to improve the approval of farmers, it is essential to design a large scale and inexpensive SCD. Research & development in solar drying technology has made significant progress. An overview of the development of solar drying technology is suitable for agricultural growth
