According to investigations around 15% of the world population today is undernourished. The increase in world population will strengthen the yet existing population–food imbalance. Besides increasing food supply and limiting population growth, drastically reducing the food losses which occur throughout food production, harvest, post-harvest, and marketing seems to be a viable option.The reduction of food losses is particularly a problem for small farmers in developing countries who produce more of the food.
Solar drying is in practice since time than 80% immemorial for preservation of food and agriculture crops. This was done particularly by open sun drying under the open sky. Since traditional sun drying is a relatively slow process, considerable losses can occur.In addition, a reduction in the product quality takes to insect infestation, enzymatic reactions, microorganism and mycotoxin development. This process has several disadvantages like spoilage of product due to adverse climatic condition like rain, wind, moist, and dust, loss of material due to birds and animals, deterioration of the material by decomposition, insect infestation and fungal growth. Also the process is highly labor place due growth, intensive, time consuming, and requires large area. With cultural and industrial development, artificial mechanical drying came into practice. This process is highly energy intensive and expensive, which ultimately increases product cost. Thus solar drying is the best alternative as a solution of all the drawbacks of natural drying and artificial mechanical drying
