Drying of coated film

Department of Chemical Engineering, Korea University, Seoul, Korea 

Here we address a subject of solvent removal, or drying, which is a part of sohdifica-tion processes. 

We are going to deal with some important features of drying a liquid coated film in the 

we will introduce theory for the drying and method of modeling of the drying proeess. A drying process of liquid coated film can be simulated by setting up heat and mass transfer equations and vapor liquid equilibrium equations with appropriate heat 

Secondly, we will try to give examples of drying rate measurements in laboratory experiments and in a pilot or produetion scale dryer. Traditionally, the rate of drying was obtained by measuring weight loss using a balanee under the eontrolled experimental eonditions of air veloeity and temperature. However, it is diffieult to obtain such data in
