In one step – Drying by fluid bed spray granulation (German article)
Thermal drying is an essential process in almost all industries to convert liquid or moist raw materials into solid dry products. In general, water or another solvent is removed from the raw material by evaporation or vaporization. A wide variety of processes and apparatus are available to carry out drying technology applications. The selection of suitable processes is usually complex and depends on the prevailing conditions. One possible basic principle for drying technology applications is fluidized bed technology. The fluidized bed is characterized by very intensive process control. (article in German language)
