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.
