There are various types of desiccants:

Among them, food packaging desiccants include silica gel desiccants, quicklime desiccants, mineral desiccants, montmorillonite desiccants, etc. Industrial desiccants include calcium chloride desiccants, biochemical desiccants, molecular sieve desiccants, etc

1. Silica gel desiccant Silica gel itself is a neutral substance. Except for reacting with strong alkali and strong acid under certain conditions, it will not react with any other substance. Meanwhile, silica gel is the only desiccant that has passed the FDA certification in the United States and can be used in direct contact with medicines and food.

2. Montmorillonite desiccant: Montmorillonite desiccant is made from pure natural montmorillonite through drying and activation. It contains no additives or easily soluble substances and is a green and environmentally friendly product that is non-corrosive, non-toxic, and pollution-free, with excellent compatibility. It can be treated as general waste.

3. Lime desiccant The main component of lime desiccant is calcium oxide. Its water absorption capacity is achieved through chemical reactions, so the water absorption is irreversible. It gets hot when it comes into contact with water and is rather dangerous.

4. The mineral desiccant is refined from natural mineral raw materials and a small amount of additives, which is environmentally friendly, non-toxic and odorless. The product has good adsorption performance at room temperature and general humidity, and has the functions of adsorption activity, static dehumidification and odor removal.

5. Biochemical desiccant: The raw materials of biochemical desiccant are derived from natural synthetic substances. It has a strong moisture absorption capacity.

6. Calcium chloride desiccant: The main raw material of calcium chloride desiccant, calcium chloride, is made from high-quality calcium carbonate and hydrochloric acid as raw materials. It is refined through processes such as reaction synthesis, filtration, evaporation concentration, and drying.
