The invention belongs to the field of agricultural product processing machineries and relates to a pulsed gas jet impact drier. The pulsed gas jet impact drier consists of an air circulating system, a material drying system, a temperature and humidity control system and a case. A material frame of the drying system adopts a four-parallel rod mechanism; a material disc does horizontal rotary movement around a material frame shaft at a constant speed under the action of the four-parallel rod mechanism; and the bottom plane of the material disc is always vertical to the direction of the air flow jet by a jet plate. When the material disc is rotated to the top, the air flow impact applied to a material is maximum and then is gradually reduced; when the material disc is rotated to the bottom, the air flow impact applied to the material is minimum and then is gradually increased; and when the material disc is rotated to the top, the air flow impact applied to the material is maximum again and then the material is dried in a pulsing manner.
