Desiccant dryers are devices used to remove moisture from the air or gases. They utilize a desiccant material, such as silica gel or activated alumina, which absorbs water vapor. This process is essential in various industries, including pharmaceuticals, food processing, and electronics, where controlling humidity is crucial for product quality and safety. These dryers operate in cycles, where the desiccant material is first used to absorb moisture and then regenerated by heating or applying a vacuum. This allows the desiccant to release the trapped moisture, making it ready for another drying cycle. Desiccant dryers are known for their efficiency and ability to achieve low humidity levels.
