Inorganic products are generally easier to dry than organic products because heat can be used as a drying agent. However, many inorganic compounds absorb large quantities of water. This is not water of crystallization- that is, it does not enter the lattice structure of the compound but it is nonetheless tightly held by the compound. When water of crystallization is involved, even the use of heat can be impractical… or damaging. But for most inorganic products, dry air may enhance operational efficiency and product quality.
