ABSTRACT

The book is laid out as follows: After the short introduction in Chapter 1, Chapter 2 presents the fundamentals of the single droplet drying, which provides an essential understanding and modelling approach. This is the key to understanding the whole process of spray drying. Chapter 3 involves information about spray drying configurations, including multistage drying with spray drying as the first stage. Chapter 4 covers the mass and energy balances, which cannot be avoided in any spray drying description. Here, stickiness, agglomeration, and CFD modelling are considered. Chapter 5 has uniquely addressed a special development in spray drying, i.e. spray drying of mono-disperse droplets, which has immensely helped fundamental research into spray drying and is usually influenced badly by the wide particle size distribution. Finally, variations of spray drying with hot gas-like air, such as superheated steam spray drying, crystallization during spray drying, and production of bio-actives, and antisolvent vapour precipitation spray drying, are described.
