The process of heating silica gel desiccants involves spreading them in a single layer on a tray and placing them in an oven preheated to 120-150°C. The heating process takes about 2-3 hours, during which the absorbed moisture evaporates, making the desiccant reusable. For industrial or large-scale applications, GlobeCore manufactures automated silica gel regeneration units. These units provide precise temperature control and consistent heating, ensuring that the silica gel is regenerated uniformly and efficiently.
