[0011] Beneficial effects of the utility model:

[0012] 1. When drying the polyester masterbatch material, first open the sealing door, inject the material into the inside of the drum pot body, then close the sealing door, and then start the first drive motor, vacuum pump and electric heating rod. The first drive motor drives the drum pot body to rotate, and the material can be thrown onto the inner wall of the drum pot body through the centrifugal force, and the material will pass through the vacuum column and the multiple electric heating rods and stirring columns next to it. The stirring column can break up the passing material, and the electric heating rod will heat and dry the passing material, and cooperate with the multiple vacuum holes on the multiple vacuum columns to adsorb the air moisture passing around the material, and the water vapor next to the material is quickly discharged through the first drive motor and the ventilation part, gradually increasing the vacuum around the material, gradually reducing the boiling point of the water attached to the material, and also making the interaction force between gas molecules gradually smaller, the free movement ability of molecules enhanced, the thermal resistance in the heat transfer process reduced, and the heat transfer coefficient increased, thereby improving the heat transfer efficiency, so that the material can be dried quickly and effectively;

[0013] 2. During the drying process, the vacuum pump can be started at the same time, so that the second rotating component drives the ventilation column to rotate in the direction opposite to the rotation direction of the drum pot body. In this state, after the material particles are injected into the drum pot body, the centrifugal force causes the material particle disk to adhere to the inner wall of the drum pot body, and the rotation of the ventilation column drives the multiple exhaust columns connected to the annular ventilation pipe to rotate in the opposite direction of the drum pot body, so that the multiple stirring columns set on the exhaust column can be effectively broken up, thereby improving the dispersion of material particles. On the one hand, the electric heating rod can effectively generate heat for the material, and on the other hand, the air and water vapor between the gaps of multiple material particles can be better extracted, thereby further improving the drying efficiency of the material.

The stirring column 14 can break up the passing material, and the electric heating rod 12 will heat and dry the passing material, and cooperate with the multiple vacuum holes 101 on the multiple vacuum columns 10 to adsorb the air moisture passing around the material, and the water vapor next to the material is quickly discharged through the first drive motor 5 and the ventilation part, gradually increasing the vacuum around the material, gradually reducing the boiling point of the water attached to the material, and also making the interaction force between gas molecules gradually smaller, the free movement ability of molecules enhanced, the thermal resistance in the heat transfer process reduced, and the heat transfer coefficient increased, thereby improving the heat transfer efficiency, so that the material can be dried quickly and effectively;

[0028] During the drying process, the vacuum pump 2 can be started at the same time, so that the second rotating component drives the ventilation column 4 to rotate in the opposite direction to the rotation direction of the drum pot body 1. In this state, after the material particles are injected into the drum pot body 1, the material particle disk will be attached to the inner wall of the drum pot body 1 through the centrifugal force, and the multiple exhaust columns 10 connected to the annular ventilation pipe 9 are driven by the rotation of the ventilation column 4 to rotate in the opposite direction of the drum pot body 1, so that the multiple stirring columns 14 set on the exhaust column 10 can be effectively broken up to improve the dispersion of material particles.
