A desiccant is a class of substances that can remove water molecules from moist substances (solid, liquid, or gaseous), thereby reducing ambient humidity. Desiccant can maintain the environmental humidity at a low level, in a dry environment, can effectively inhibit the growth of mold and other bacteria, the product oxidation acid failure process slows down, prolongs the shelf life of food, improve economic efficiency.
Desiccant sits in two categories, chemical desiccant and physical desiccant according to its drying principle. Chemical desiccant is a substance that absorbs water and is often accompanied by a chemical reaction, and the physical desiccant simply absorbs the water and does not accompany the chemical reaction.
The principle of physical desiccant mainly relies on adsorption to remove water molecules from wet substances, that is, it is adsorbed on to the solid material surface by means of mutual attraction between the mass points of the solid surface and the water molecules in various gases, liquids, etc. Most desiccants have a lot of pores and have a large surface area.
At present, the most common application is silicone desiccant, belongs to the physical type of adsorption, silicone itself is a neutral substance, in addition to strong alkali, strong acid in a certain conditions, will not react with other substances. At the same time, silicone is also certified by the U.S. FDA, can be used in direct contact with food desiccant, very safe.
