The food dehydrator solves this problem and many local hardware stores 
have them.

Our beloved "standard" FD-50 is discontinued, but the FD-60/61 are 
compatible with the same trays and I do have a 61 which my wife found 
for me at the local Home Hardware when I needed a "mold baker" to keep 
out of the main production run.

The FD-1010 is needed for over 12.5" reels but will not hold 14-inch 
reels, but will hold the pancakes.

And for the trays

The beauty of these is the circulating air goes OUT and takes the 
moisture and who knows what else with it.

I would prefer NOT to use a radiant heat source with no air movement. 
Some people have luck with hair dryers, but the Nesco units have 
thermostats, but please do check your unit with a thermocouple placed 
inside as you first commission it. Many inexpensive Digital Thermometers 
come with a remote temperature probe. Typically marketed as 
Indoor/Outdoor. Also some digital multimeters used to come with a 
thermocouple and I have a few, but the Radio Shack thermometers seem 
more accurate. I would check the outdoor probe against a few liquid 
thermometers to be certain.

Cheers,

Richard
