ZPG Vacuum Paddle Dryer

I. Overview of Vacuum Paddle Dryer Equipment

The vacuum paddle dryer is primarily used for drying explosive, easily oxidizable, and paste-like materials. Under vacuum conditions, the boiling point of the solvent is lowered, while air is isolated, preventing oxidation and overheating degradation of the material during the drying process. Heating medium (hot water, thermal oil, steam) is introduced into the jacket, and a certain amount of wet material is added into the cylinder. The paddle shaft stirs the material to ensure uniform heating. Once the material meets the drying requirements, the discharge valve at the bottom of the cylinder is opened, allowing the material to move toward the center under the stirring of the paddle shaft for discharge.

II. Features of Vacuum Paddle Dryer Equipment

1. This machine adopts a large-area jacketed heating method, offering a large heat transfer area and high thermal efficiency.

2. High evaporation intensity, generally capable of evaporating 10~15 kg (water)/m².h.

3. Solvent vapor carrying materials is filtered through a bag filter, resulting in no environmental pollution and a high product recovery rate.

4. The machine is equipped with a stirring mechanism, enabling smooth drying of slurry, paste, and paste-like materials.
