solar dehydrator plus diatomatious earth

Does coating your food product in food grade diatomatious earth before loading it onto a solar dehydrator's trays  have a noticeable effect on drying time?
I'd test this out myself but I lack a dehydrator currently.

Yours curiously,

I cannot prove it, as I have not tested it, but having dehydrated things for 30 years or more, I'd say
A) The powder would block airflow and impede drying
B) the residual grit would be rather concentrated, might make for more crunch than desired. I bought some dehydrated mushrooms once that had what was probably a minor bit of sand on them when they were dried, and I never used them without excess grit. I couldn't remove it. Might be a similar issue, not sure.
