Despite many disadvantages of natural drying, almost 80 % of farmers are using open sun drying method for drying their crops. Open sun drying, in which the product is spread on ground in open, is the simplest and cheapest method of drying. But there are considerable losses associated with it. So, the advanced method of drying i.e. greenhouse drying can also be used for drying the products and improve the quality. In this paper, a comprehensive review of open sun drying and greenhouse drying of various products are presented.
