HOW DOES DESICCANT WORK ?
A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant. Commonly encountered pre-packaged desiccants are solids that absorb water. Desiccants for specialized purposes may be in forms other than solid, and may work through other principles, such as chemical bonding of water molecules. They are commonly encountered in foods to retain crispness. Industrially, desiccants are widely used to control the level of water in gas streams.
Desiccants protect products through a process called “ad”sorbtion. Unlike “ab”sorption where one substance is chemically integrated into another, during adsorption, moisture is held inside a desiccant by physical bonds; no chemical change takes place. Along with protecting products from external elements, a certain amount of moisture inherent in all hygroscopic (moisture absorbing) items can also be trapped within chambers. Desiccants adsorb this moisture quickly and thoroughly, preventing condensation during transport and storage.
