Introduction to Sodium Hypophosphite Drying

Sodium hypophosphite (NaPO₂H₂) is a versatile inorganic compound widely used as a reducing agent in electroless nickel plating, pharmaceuticals, and polymer stabilization. Drying is a crucial step in its production process to ensure product purity, stability, and suitability for industrial applications. Effective drying removes residual moisture, prevents caking, and maintains the compound’s chemical integrity, which is sensitive to humidity and temperature.

Importance of Drying
Sodium hypophosphite is hygroscopic and prone to absorbing moisture from the environment, leading to clumping, reduced reactivity, or decomposition. Proper drying preserves its white crystalline form, enhances shelf life, and ensures consistent performance in critical processes like metal plating, where precise chemical activity is essential.

Common Drying Equipments:

Vacuum Drying: Preferred for its low-temperature operation, vacuum drying minimizes thermal degradation. Moisture is evaporated under reduced pressure, preserving the compound’s stability.

Fluidized Bed Drying: Combines efficient heat transfer and gentle agitation to achieve uniform drying, ideal for large-scale production.

Paddle dryer: Paddle dryer is a kind of horizontal stirring type continuous drying equipment which is mainly used for heat conduction. Because the stirring blade is shaped like an oar, it is called paddle dryer.
