Basic concepts of spray dryer design Gauvin 1976

Abstract. The major parameters in the design of spray dryers are discussed. A Lagrangian approach, combining experimental data with theoretical concepts, is proposed to develop design methods. Vortex flow patterns, obtained experimentally in a laboratory size chamber, are correlated and presented. Based on this design methodology, computational ...

2.2 Counter-current flow dryer In this dryer design (Fig. 2.2.1), the spray and the air . are introduced at opposite ends of the dryer, with the atomizer positioned at the top and the air entering at . the bottom. A counter-current dryer offers more rapid evaporation and higher energy efficiency than a co- current design.

PDF Design and Operation of a Spray Dryer for the

Spray drying is the process of transforming a liquid into a dry, particulate solid by atomizing the liquid and bringing the liquid in contact with a hot gas. Such a process may be achieved in a spray drying chamber. Spray dryers are extensively used in many industries such as the food industry to dry the liquid feed when close control over the product size distribution is needed.

Spray Freeze Drying as a Solution to Continuous

Jun 19, 2020 2. Principles of Spray Freeze-Drying The concept of SFD dates back to the late 1940s, when Benson and Ellis [12] successfully applied the process to produce protein particles having different values of specific surface area. Their process concept included the spray freezing of solution into a liquid nitrogen bath, followed by vacuum freeze-drying.
