Food steaming and refining machine with uniform heating function

The utility model relates to the technical field of food steaming and refining machines, and discloses a uniformly heated food steaming and refining machine, which comprises a base and a protective cover, the surface of the base is fixedly provided with a steaming and refining machine, an electric stirring rod is arranged in the steaming and refining machine, and the steaming and refining machine is internally provided with a feeding port. By arranging the control assembly, heat generated when the steaming and refining machine works enters a thermal expansion air bag from a heat conduction pipe, the thermal expansion air bag is heated to expand in a fixed frame, the thermal expansion air bag abuts against a movable disc to move under supporting of a spring in the expansion process, and a transverse rod fixed to the surface of the movable disc moves out of the fixed frame; the rack fixed to the surface of the transverse rod moves on the surface of the gear, the gear is stressed to drive the disc to rotate thro
