The moisture content in the solid silica gel used in this project reaches 75%. The samples are glass-like and transparent, and are relatively hard, making it impossible to remove the water by squeezing. In collaboration with the client, our company has developed a novel spray dehydration method capable of instantly removing moisture from the three-dimensional molecular structure of solid silica gel, reducing it to less than 3%. This process also increases the product’s pore volume to some extent, thereby enhancing its performance. The system was designed and put into operation at a facility in Rizhao, Shandong, achieving a continuous, automated production capacity of 1,000 kg of water evaporation per hour.
