The invention relates to a multiple-effect drying technology which is characterized in that air serves as drying medium and directly contacts with material to be dried to take away moisture and provide heat; multiple stags of drying chambers connected with a heater and a heating device are connected in series to form a simulated moving bed operation mode; air lead out of the last stage is subjected to heat exchange by an air heat exchanger to heat dry medium of the last but one stage; air led out of the last but one stage is subjected to heat exchange by the air heat exchanger to heat the drying medium of the last but two stage; and the rest can be deduced by analogy. The multiple-effect drying technology has the advantages of energy saving and high efficiency, is efficient and quick and is simple to manufacture.
