This is how it all began, I have a 100% rye starter for about a year now.  I used a spoon that had some other dough on it, that dough was from a bag of flour that had mentioned at the bottom of the packaging, it had some leavening improvers.  Assuming that's commercial yeast? Either way, will this commercial yeast, should it be in my starter, wreak havoc on my natural wild starter? Will the wild strands kill it off? 
No, it won't work. You don't need to dry out your rice for making fried rice. Instead, you want the starch in your rice to undergo retrogradation. Starch retrogradationis a process which starts out with cooking the starch and continues over a few days after the actual cooking has finished - it is the same process that makes bread stale. And the quickest way to achieve retrogradation is at fridge temperatures. So, you are already making your fried rice by the quickest way possible, which involves an overnight stay in the fridge. If you were to dry your rice by some other means, be it an air fryer or something else, you might get it dry quicker, but it won't be the right texture for making fried rice.
