Since ancient times, conventional techniques of food drying, such as sun drying, have been used.  Currently, drying methods have been developed with the latest technology to reduce the damages caused by biochemical changes, which decrease nutritional value during the drying process. Some of the typical drying methods used for food products are sun drying, solar tunnel dryer, cabinet-type solar drying, etc. While this is going on, cutting-edge technology is being created to combine several drying techniques to produce the optimum outcomes. The most recent drying techniques used in food processing technology will be covered in this study.

Keywords: Food drying, techniques, damages, solar tunnel drying, cabinet type solar drying, combinations
