[0022] In this embodiment, after the transported hot air enters the insulation sleeve 512, it can enter the sealing frame 52 through the air guide pipe 59, and then enter the rotating rod 52 and the stirring rod 54 in turn to heat the inside and outside of the material at the same time, thereby improving the heating effect of the material and reducing energy consumption. At the same time, after the hot air overflows, it can be guided through the air inlet pipe 511 and the exhaust pipe 57 to heat the water flow in the water tank 58, so as to facilitate the energy conversion of the hot air, making the vacuum furnace more energy-saving during use.
[0023] The interior of the rotating rod 53 is hollow, and an air inlet hole 511 is opened at the upper end of the rotating rod 53. The air inlet hole 511 is connected to the hollow part of the rotating rod 53, so that after the transported hot air enters the sealing frame 52, it can enter the rotating rod 53 in turn through the air inlet hole 511.

The interior of the stirring rod 54 is hollow, and the hollow part of the stirring rod 54 is connected to the hollow part of the rotating rod 53.
