FD was first utilized for manufacturing instant coffee in foreign countries and development of ingredients for instant noodles in Japan.FD is a drying technique utilized for various kinds of foods and for the field of medicine.

This method minimizes changes in color, taste, flavors and vitamins in the dried product and allows them to be stored with a low moisture content.
