In the 1960s, the United States would use the technology to produce freeze-dried food as astronauts' space food; In the 1970 s, with the speeding up of industrialization process, digestion, absorption, the FD for scientific and technological achievements in the United States, Japan, and carries on the thorough research, make the FD technology and the equipment in the field of food processing and application has achieved further development, from then on, FD products and equipment into the era of the industrialized production, mainly used in pharmaceutical, beverage, food, and the low temperature drying of agricultural and sideline products.
