In spray drying, droplets are sprayed or a liquid is atomized into a temperature-controlled room. The dried particles are collected at the end and can be further processed.
Before the liquid starting material is dried, it is first converted into droplet form during spray drying. This is done with the help of an atomizer, which distributes the atomized material evenly into the drying medium – usually tempered air in a spray tower. The liquid to be dried has a larger surface due to the drop shape, which can accelerate the drying process enormously.
