[0002] Pearl pigment is a decorative pigment widely used in cosmetics, coatings, plastics, and many other fields. Drying is a crucial step in the production of pearl pigment, as its drying effect directly affects the quality and performance of the pearl pigment.

[0003] The existing pearl powder dryer technology is mature. It involves feeding the damp pearl powder into the drying drum and then heating the inside of the drying drum (there are various heating methods, such as hot air, gas heating, electric heating, etc.). During the rotation of the drying drum, the pearl powder is dried evenly, so that the moisture in the pearl powder is forced to evaporate and be discharged. After drying is completed, the drying drum is opened and reversed to discharge the material.
