new to dehydrating, just got new excaliber dehydrator

I am confused if I can just dry food on the mesh sheets or if I need some sort of cover sheet. I have read of people mentioning something like a "tyflex" sheet or something. Could wax paper, alluminum foil or parchment work suffiicently?

could one exclusively use parchment then? Just wondering why Teflex would be used vs parchmt

So...I just recently purchased a dehydrator myself...I attempted to dehydrate green beans and they came out chewy, which was NOT the result I expected. I dehydrated them for about 12 hrs....maybe it wasn't long enough? I figure it's a trial and error thing, so I decided to dry and dehydrate daikon in an attempt to make daikon chips....well the "chips" ended up being the size of pennies, if not smaller! I'm getting a tad bit frustrated with the dehydrating....any advice?
