Comparative Study of Solar Drying of Vegetables and Spice Materials with Open Sun Drying (original) (raw)

Generally farmers of India dried food and spices for preserving them for a long time, earlier they used to dry the product in open sun drying by spread the product on the ground. They are during it for a long decade but this method is not good or hygienic and that result in significant loss in product, specially dist, dirt, insect, animal, and human interference affect the produce. For saving the products from these kinds of losses and problem many different technologies are developed like different kind of solar dryer. In this research we are comparing three different methods of drying these are direct radiation solar dryer, indirect radiation solar dryer and open sun drying of the product. This research was conducted in Centre of Excellence, Solar energy Research & Utilization Gyan Vihar University Jaipur (raj.). In this research mainly we dried the spices and comparing the drying rate and dryer efficiencies in all three kind of drying methods. This research was conducted in May-J...
