Applications Involving Drying -- Using Kinetic Models

[Tung Jian Seng]

Hi, I am a mechanical student. I would like to ask are those drying kinetic equations for food drying applicable in drying a paperboard?

Thankyou :)

Probably, but you need to specify what "those" equations are.
Food drying, modeled as thin layers, may be significantly thinner than paperboard.
Depending on the model it may or may not hold for thicker sheets of material.
How thick is the paperboard ?
Can you provide a link to "those" kinetic drying equations ?

You can answer that for yourself by examining the assumptions in those equations. For instance, paperboard is dried by putting one side in firm contact with a surface heated by steam at about 300 deg F for a short time, then putting the opposite side in firm contact with a similar surface. That process is repeated until the paper is dry.

If the food drying process is similar, then similar equations could apply. Your job, as a student, is to look closely at the respective processes, and how the equations relate to the processes. Then your question will answer itself.
