In this video I show how to model a drying process but quite differently. If you need to control the moisture content this is one way to model a drying process.
This is a video walkthrough of Chemical Engineering Process Modelling course material using Aspen Plus V9.
The method is loosely based on "Getting Started Modeling Processes with Solids" https://esupport.aspentech.com/S_Article?id=000064733
