Food desiccant refers to the substance that can remove the water in the moist material such as calcium sulfate and calcium chloride, etc., and dry by combining with water to generate hydrate. There are mainly quicklime, silica gel, calcium chloride, montmorillonite.

1, quicklime desiccant The main component of quicklime desiccant is calcium oxide, and its water-absorbing ability is realized through chemical reaction, so water absorption is irreversible.

2, silica gel desiccant this desiccant is permeable sachet packaging of different varieties of silica gel, the main raw material silica gel is a high microporous structure of the water-containing silicon dioxide, non-toxic, tasteless, non-smell, chemically stable, with strong hygroscopic properties.

3, calcium chloride desiccant main raw material is calcium chloride, is the use of high-quality calcium carbonate and hydrochloric acid as raw materials, through the reaction synthesis, filtration, evaporation and concentration, drying and other processes refined.

4, montmorillonite desiccant This desiccant is made of pure natural raw material bentonite, which is green, non-toxic, tasteless and harmless to human body.
