this might not be the right place to ask :
the units have a
" 5 plastic trays with BPA free mesh screens "
then
" fruit puree for fruit roll-ups "
on the web site you can see them make the fruit roll up
do you do this on ' mesh ' ?
rather than a solid backing ?
thanks
P.S.:
you can put parchment paper on top of the mesh for the fruit roll ups.
Yikes.
