Disclosed is a rotating intelligent microwave puffing drying mixing machine. The rotating intelligent microwave puffing drying mixing machine comprises a rotating metal shell. The metal shell is a pressure vessel and bears the internal pressure ranging from 1.5MPA to 2.5MPA. Rotating shafts of the metal shell are hollow shafts, the hollow shafts are fixedly connected to the left end and the right end of the rotating metal shell, and the metal shell is a completely symmetrical metal structural body by using the center lines of the rotating shafts as the axes. The hollow shafts are fixedly connected to a rigid metal base through bearings and bearing pedestals, a motor and a decelerator are fixedly arranged on the left bearing pedestal, and the metal shell is driven by a transmission mechanism to rotate. The intelligent microwave puffing drying mixing machine further comprises a microwave magnetron tube, wherein the microwave magnetron tube is fixedly connected to the left bearing pedestal and transmits microwave energy to the metal shell through a metal pipeline and the left hollow rotating shaft of the metal shell. The rotating intelligent microwave puffing drying mixing machine has the advantages of being uniform, rapid and free of pollution, and saving energy and reducing emission.
