Hi folks, just wondering should there be any concerns dehydrating (at 40 deg or less) with a plastic container at all? In particular, this one: http://www.ikea.com/ie/en/catalog/products/60166733/

Just to dry out things like buckwheat, I have a TSM dehydrator and the trays are pretty big, but when I dry out buckwheat, even having folded the sides of bakers parchment paper, you still get little bits of buckwheat being blown around.

Any feedback appreciated or suggestions on tray type holders that will still give a good drying environment.
