More on Vacuum Drying
 

Here is some information I've found that was useful to me. There seems to be
three methods of vacuum drying. 1. Cyclic temperature and vacuum (used by
commercial dryers) 2. Constant vacuum with fresh air intake using heated
shelves 3. Constant vacuum using ambient heat (as in the article below). All
methods seem to use 15-18mm Hg vacuum. Dan
