Spray Drying of Sodium sulphite

Application Note Mini Spray Dryer B-290 Sodium sulphite
Spray Drying of Sodium sulphite

Spray drying is a commonly used technique to produce dry powders from liquid solutions, such as sodium sulphite, for improved handling, storage, and transport. Sodium sulphite is a chemical compound commonly used as a reducing agent, preservative, and oxygen scavenger in various applications, including food processing, paper and pulp production, and water treatment.

The spray drying process involves atomizing a solution of sodium sulphite in a solvent into a fine mist, which is then rapidly dried in a stream of hot air. The resulting dry powder consists of small, spherical particles with controlled size and shape. The process allows for the production of a large quantity of uniform particles with excellent flowability and dispersion properties.

The properties of the sodium sulphite powders produced by spray drying can be tailored by adjusting the process parameters, such as the inlet temperature, feed rate, and drying time. The use of different solvents or drying aids can also affect the properties of the final powder.

Overall, spray drying is an effective method for producing sodium sulphite powders with controlled properties, which can improve the performance and efficacy of the final product. The process allows for the production of a large quantity of uniform particles with excellent flowability and dispersion properties, which can enhance the reducing and preservative properties of the compound.
