Vacuum Tray Dryer Working Principle

A vacuum dryers upper temperature limit typically about 600 F is lower than that of a directheat dryer The rate at which material temperature can be raised in a vacuum dryer is also limited This is because the indirectheat vacuum dryer is limited by the surface area available for heat transfer unlike a directheat dryer
