A vacuum dryer is a type of drying equipment that removes moisture from materials by creating a low-pressure environment. This process lowers the boiling point of water, allowing it to evaporate at lower temperatures, which helps preserve the quality of heat-sensitive products. Vacuum dryers are commonly used in industries such as pharmaceuticals, food processing, and chemicals. These dryers typically consist of a sealed chamber where the material is placed, along with a vacuum pump that removes air. The reduced pressure inside the chamber enhances the drying efficiency and minimizes oxidation, making vacuum dryers ideal for sensitive materials that require gentle handling.
