Spray Drying of Diatomaceous earth
Spray Drying of Diatomaceous earth with the Mini Spray Dryer B-290
Diatomaceous earth is a naturally occurring sedimentary rock that is commonly used as a filtration aid, insecticide, and abrasive. Spray drying is a popular method used to produce dry powders of diatomaceous earth, which can improve its handling, storage, and processing.
During the spray drying process, a diatomaceous earth slurry is atomized into fine droplets and dried in a hot air stream to produce a dry powder. The resulting powder has good flowability, uniform particle size distribution, and high purity, making it ideal for various applications.
Areas of spray drying of diatomaceous earth include the selection of appropriate raw materials, formulation development, process optimization, and product characterization. The optimal processing conditions such as temperature, flow rate, and inlet/outlet conditions are determined to optimize the particle size, powder yield, and other physicochemical properties of the resulting powder.
Spray-dried diatomaceous earth powders are commonly used in various industrial applications, such as in filtration systems, insecticides, and abrasives. The use of spray drying technology ensures consistent quality and high production efficiency, making it a preferred method for producing diatomaceous earth-based dry powders.
