Silica Gel has Highest Priority in Desiccants!!!

Among all the desiccants, silica gel is rated as the best one.  It is basically amorphous form of silicon dioxide. These are hard irregular beads which has high capacity surface area to not only absorb water molecules but also lock it inside them. It is available in three variants that is blue, white and orange.  Among them Blue and orange are the indicating types. It changes its color to indicate that they are fully contaminated and are now ready to be replaced with the fresh ones. Also these beads should never be used in direct contact with any food or pharmaceutical product. The best thing about the gel is that once it is fully contaminated it can be reused by heating it over 300oF. The heating process brings the silica gel beads to its original face.
