desiccant dehumidifier

how can i build a desiccant dehumidifier and which comes first among its parts?
is it possible to build it’s fan facing upward?please help me,i need this for my feasibility study..thanks
It’s basically a lot of desiccant and a fan to blow air from the room over the desiccant and back to the room.
You can have the fan facing any way you want, as long as it circulates air over the desiccant and back to the room.
Remember that you have to replace the desiccant frequently. For that reason, they are not very popular.
