How to Dry Pressed Plants?

I find that approximately 5 days in the press is sufficient 
for specimens to dry without a drier.  I have had few
problems with with classes of 15 students, making 30 
specimens each--perhaps not as large a group as yours.  

You can speed drying by placing presses near heat ducts so 
the air blows through the ventilators.  Also, you can put 
the presses in a dry room (some utility rooms are good).  
My gut reaction about the light bulbs is that they are a 
fire hazard.

I've heard stories of early- to mid-20th century botanists 
strapping presses to the tops of their cars while they drive
around on collecting trips.  I haven't used that one, but 
my students find the imagery amusing.
