Solids Drying Basics and Applications Chemical

Freezedrying is an extreme form of vacuum drying in which the water or other solvent is frozen and drying takes place by subliming the solid phase. Freezedrying is extensively used in two situations 1 when high rates of decomposition occur during normal drying and 2 with substances that can be dried at higher temperatures, and that are ...

Modelling batch drying of sand in a draft tube conical

Modelling batch drying of sand in a draft tube conical

The conical spouted bed is an interesting alternative since it is characterised by efficient heat and mass transfer resulting in higher drying rates and a compact and simple design. However, in other drying devices, such as rotatory dryers, the gassolid contact is poorer and hot air must be used to increase drying rates, which means higher ...
