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 by passing humid air through a chamber filled with desiccant. As the air flows through, the desiccant captures moisture, resulting in dry air being released. Once the desiccant becomes saturated, it can be regenerated by heating or using a vacuum, allowing it to be reused for moisture removal.
